hi st-community,as i'm newbie embd engr.,i have limited knowledge of using to select mcu or mpu in stelectronics or any.so please suggest me for custom hardware making using stm32..as i have basic understanding of st-world..from past 5 month.I have tested the STM32F769I-DISCO for 12-lead ECG data acquisition and printing using a thermal printer, with a GUI  TouchGFX as the basis. Now, I need to finalize the choice of chip for our multi-parameter patient monitor application.1. is there any way for developing custom HW like using project files for discovery board to import in altium and able to customize to our need ..thats all i needed to do..2.  I've selected the STM32MP15 (dual core -800mhz main) as my processor for better handling, especially for external RAM memory like LPDDR3. Considering future development, would starting with custom hardware based on the high-level STM32MP15 be the best option?3.where, my previous post, i didn't get replay..where they told f7 is suitabl

 Hi, I'm working on STM32F746G-DISCO. Kindly can someone tell me if it is normal that after making some project screens on TouchGFX and launching the SIMULATOR, everything is ok. I open the project with CubeIde and add some code from the IDE and transfer it to STM32F746G-DISCO it continues to work, if I try to simulate it with the TouchGFX SIMULATOR I can no longer make it work and it gives me errors right in the lines of code I have added. Thank you.

Dear Experts,I’m currently working on a project involving an STM32 board (B-U585I-IOT02A). I would like to use this board as a TCP Server . Therefore, from the STM32CUBEIDE application, I had observed that there is an example project in which it is possible to render this board as a TCP Server (Nx_TCP_Echo_Server). However, my problem was that it only returns the value returned by the TCP Client. So, I wanted to modify this program so as to be able to retrieve the temperature parameters. So, I created a program based on an example (https://wiki.st.com/stm32mcu/wiki/STM32StepByStep:Step4_Sensors_usage). I wanted to combine these two programs to retrieve the temperature data.To sum up, the diagram is as follows:After activating the I2C module in the hal_conf.h file, I had no errors during debugging and was able to retrieve the temperature when sending a request from Node-Red. Nevertheless, this program has a number of flaws. The number of requests is limited, as you can see in the image

Hello,We are in the process of integrating TouchGFX into our workflow and back-end build systems. We are using a STM32U599. Please see my question with respect to the tree belowWhat is the difference between TouchGFXNema and NemaGFX libraries?What does the wc16 suffix on the libraries mean? Middlewares/ST/touchgfx_components/ └── gpu2d ├── NemaGFX │ ├── include │ └── lib │ └── core │ └── cortex_m33 │ └── gcc │ ├── libnemagfx.a │ ├── libnemagfx-float-abi-hard.a │ ├── libnemagfx-float-abi-hard-wc16.a │ └── libnemagfx-wc16.a └── TouchGFXNema ├── include │ └── touchgfx_nema └── lib └── cortex_m33 └── gcc ├── libtouchgfxnema.a └── libtouchgfxnema-float-abi-hard.a  

I am testing the development board STM32U5A9J-DK with THIS and trying to run the GPIO Toggle example program. But during the build process I get the error fatal error: stm32u5xx.h: No such file or directory.I am using CubeIDE version 1.14.1.How to fix this problem? 

Hi All, I am facing problem with RTC in STM32.i have written function in my code where i am updating display function for time every 1 min. But whenever i am trying to  see the updated time in free running mode i am unable to see that. But it works fine in debugging mode or at power on or when i program microcontroller. Please suggest what can be done to resolve this issue? Thanking you in advance.

Enabling analog watchdog 1 for ADC3 on a STM32H723 in CubeMX with low threshold 0x8 and high threshold 0x80 generatesLL_ADC_SetAnalogWDThresholds(ADC3, LL_ADC_AWD1, 0x80, 0x8);but the doc comment for LL_ADC_SetAnalogWDThresholds() says regarding the third parameter * @param AWDThresholdsHighLow This parameter can be one of the following values: * @arg @ref LL_ADC_AWD_THRESHOLD_HIGH * @arg @ref LL_ADC_AWD_THRESHOLD_LOWindicating that the correct code to generate would be LL_ADC_SetAnalogWDThresholds(ADC3, LL_ADC_AWD1, LL_ADC_AWD_THRESHOLD_HIGH, 0x80); LL_ADC_SetAnalogWDThresholds(ADC3, LL_ADC_AWD1, LL_ADC_AWD_THRESHOLD_LOW, 0x8);However neither produces the desired result. The code generated by CubeMX sets the lower threshold to 8, whereas the code I assumed to be correct sets it to 0x88. The high threshold is left at the reset value of 0xFFF in both cases.Looking at LL_ADC_SetAnalogWDThresholds() the line MODIFY_REG(*preg, AWDThresholdsHighLow, AWDThresholdValue << ((AWDThr

The logic in functions HAL_SAI_Abort() and HAL_SAI_DMAStop() is flawed because the sequence of actions is wrong. A proper sequence is:Disable the SAI and wait for it to be actually disabled.Stop the DMA.Flush the SAI FIFO.In the current implementation the function SAI_Disable() is called after stopping the DMA. This causes a SAI underrun and a data glitch at the end of stream. The bug seems to be present for all series with SAI peripheral.Also the two functions do almost the same and the code is also almost the same, which is an example of a bad and bloated design.

In LwIP examples for NUCLEO-H723ZG, in the linker, I think that there is an incorrect range of RAM_D2 memory.For example here: MEMORY { ITCMRAM (xrw) : ORIGIN = 0x00000000, LENGTH = 64K RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 128K ROM (rx) : ORIGIN = 0x08000000, LENGTH = 1024K RAM_D2 (xrw) : ORIGIN = 0x30000000, LENGTH = 288K }SRAM available from 0x30000000 has 32 kB availablefrom  the reference manual:Or am I missing something? I am writing here before creating an issue on GitHub as I am not sure I am not misreading something. I think they took it from the STM32H74x/H75x devices as those have this amount of memory.The example works correctly as the addresses used are hard-coded in the application, but the size should be correct either way. 

I'd like to use an STM32C011F4P6 as a transceiver between USARTs 1 and 2.As a first approach, I've set both USARTs to 9600bd, and I want anything that's incoming on one of them to be directly sent to the other. In both directions at the same time.In the USART1 and USART2 configuration I enabled NVIC interrupts for both of them.I then created a HAL_UART_RxCpltCallback() in section 4 in my main.c: void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart) { /* Prevent unused argument(s) compilation warning */ //UNUSED(huart); if (huart->Instance == USART1) { HAL_UART_Transmit_IT(&huart2, huart1.pRxBuffPtr, 1); HAL_UART_Receive_IT(&huart1, huart1.pRxBuffPtr, 1); } else if (huart->Instance == USART2) { HAL_UART_Transmit_IT(&huart1, huart2.pRxBuffPtr, 1); HAL_UART_Receive_IT(&huart2, huart2.pRxBuffPtr, 1); } /* NOTE : This function should not be modified, when the callback is needed, the HAL_UART_RxCpltCallback can be implemented in the user file. */

using STMCubeMx 6.1.2 on a STM32H723The code generator does not generate this line in hal_msp.c / HAL_SPDIFRX_MspInit()GPIO_InitStruct.Alternate = GPIO_AF9_SPDIF;The consequence is that the pin behaves like an output forced to 0 instead of behaving like an input, which obviously prevents SPDIFRX from working.The problem occurs at least for the 2 first SPDIFRX input lines.

Hi every ones. Where I can found L7915CV negative voltage regulator spice model? Or other equivalent spice model of other negative regulator. I saw that it is obsoleted.

I am looking for a alternative chip to replace an obsolete part.The part is a ST UAA4003DP This a 16 pin chip used in a DC motor drive to control the motor speed.I can't find any information on this other than the fact that it is obsolete.. I did find a data sheet for a UAA4000 chip, but it is for a remote control transmitter. 

Hi, I have a STM32F407 Discovery Board and I'have made full cihp erase. But I have no idea what I can do after doing this. In the communtiy I have read that I have to install the original firmware. How can I do that? Can you help me? Thanks from now.

Hi there,I am receiving a hardfault when erasing pages of flash, seemingly randomly. I can recreate the issue somewhat consistently if I rapidly erase flash pages. I have followed the example project from the STM32WB firmware package (erase flash example). This is my function for erasing flash. flash_status_t user_flash_erase_page(uint8_t page_number, uint8_t number_of_pages) { // static FLASH_EraseInitTypeDef EraseInitStruct = {0}; static FLASH_EraseInitTypeDef EraseInitStruct = {0}; if(HAL_FLASH_Unlock()!= HAL_OK) { return FLASH_ERROR; } /* Clear OPTVERR bit set on virgin samples */ __HAL_FLASH_CLEAR_FLAG(FLASH_FLAG_OPTVERR); EraseInitStruct.TypeErase = FLASH_TYPEERASE_PAGES; EraseInitStruct.Page = page_number; EraseInitStruct.NbPages = number_of_pages; uint32_t page_error = 0; if (HAL_FLASHEx_Erase(&EraseInitStruct, &page_error) != HAL_OK) { HAL_FLASH_Lock(); return FLASH_ERROR; } else { HAL_FLASH_Lock(); return FLASH_OK; } return FLASH_

  As mentioned above, I encountered a similar issue before when using the L0 series, and at that time, I chose to abandon hardware I2C in favor of software emulation. Now, with the STM32G431, when I use LL_I2C_HandleTransfer to configure continuous reading of multiple data along with LL_I2C_MODE_AUTOEND, after the first read operation completes the specified number of bytes, it automatically triggers a STOP condition, which is as expected. However, upon the second invocation of this code segment, I noticed that after reading the last byte, the SCL remains pulled low. This behavior seems equivalent to the I2C peripheral being stuck. The STM32, as the master, should not keep the SCL pulled low without performing any operation at any point.On the first read operation, a STOP condition was automatically triggered after reading 6 bytes of data, which is normal.When I call the same function for the second time to read data, after the last byte is read, the SCL remains pulled low, which

I have an issue with adding files to a project I have using the STM32 VSCode extension. I have been working on this project for some time without issue. However, today I needed to add a new source file, I opened STM32CubeIDE and added the source file and entered a small stub function. The project compiled in CubeIDe, so, I switched back to VSCode, my preferred IDE. When I opened the new file I saw a very short red "squiggle" at the very first character position. When hovering the cursor over this I get the message "command line error: language modes specified are incompatible. C/C++(1027)".The project builds within VSCode just fine; however, IntelliSense is inoperable withing the file. This makes editing much harder and I would like to know how to resolve this issue.I have tried deleting the additions and redoing them, the result is always the same.

Hi,I am currently using the M3_CryptoFW_RngHW_2_0_6.lib for MDK-ARM. However, I must adhere to this specific library version, and I now need it for IAR, meaning that the required library is M3_CryptoFW_RngHW_2_0_6.a. How can I obtain this version for IAR?Thank you,Ari

I want to set up error handling for my CAN messages, and I wanted to start with errors from sending messages to IDs not on the CAN bus net. However, every message I send is acknowledged. There is only stm32 chip set up on the net and the rest are currently TMC Pandrive motors. I am sending messages to individual motors with different IDs without issue - they're received and the motors react accordingly. So I am not sure how or why these messages to other CAN IDs are acknowledged. Below is the code I use in my CAN interface file.  #include <CANInterface.h> CAN_RxHeaderTypeDef rxHeader; CAN_TxHeaderTypeDef txHeader; std::vector<uint8_t> canRX(7, 0); CAN_FilterTypeDef canfil; uint32_t canMailbox; void HAL_CAN_RxFifo0MsgPendingCallback(CAN_HandleTypeDef *hcan1) { std::vector<char> sendBuf(60, 0); uint8_t bufLen = sprintf(sendBuf.data(), "response triggered\r\n"); HAL_UART_Transmit(&huart5, (uint8_t *)sendBuf.data(), bufLen, 200); HAL_CAN

"Hi,I am trying to read an ADC value from the feedback of a PWM signal generated via TIM3 PWM.TIM1 generates a PWM signal with 4 channels, including complementary channels. The CCR value updates from the Sine table using DMA.The ADC is being read when the TIM1 update event occurs. The ADC data is saved to the buffer via DMA.However, when I try to read the ADC, the data is only saved alternately.Why is this happening?"  

Dear all!I'm working with a custom board. I would like to make a simple application (without Lora). Just sending packets that the device receives from Uart over the air to another device. 1st approch will be only in one direction to keep it simple.Some entries unter middleware are selected and grayed out. Middleware-SubGHZPHY: It is selected, grayed out. I can't configure anything and there is no 'middleware' folder/code in the generated code. Do I have to add the code manually?Middleware-Freertos: It is selected, grayed out.  I can't configure anything and the code doesn't look like rtos (no threads and so on.FYI: I have activated SUBGHZ.Does anybody know a simple example/tutorial, how to start with an simple application, that sends packets from one device to the other device? Thanks!best regards

HelloSTM8S microcontroller. Cosmic compiler. How can I find out how much memory my C program is using and for what purposes?

Hello, STM32 community,I am currently working on a project using the STM32H755ZI-Q Nucleo board, and I've encountered a perplexing issue with the M4 core during debugging. I have written a basic code to toggle two onboard LEDs, and while the code seems to work as expected, the M4 core gets stuck at "Waiting for Debugger Connection" during debugging. Strangely, I can still add breakpoints in the M4 code and pause the LED toggling successfully. The project files are attached. Please can someone help me with resolving the debugging issue for M4? If you find this post irrelevant feel free to delete it.Solutions I tried: https://community.st.com/t5/stm32cubeide-mcus/stm32h755-dual-core-debugging-problem/m-p/608795#M22058https://community.st.com/t5/stm32cubeide-mcus/how-can-i-remove-error-like-waiting-for-debugger-connection/td-p/250559/page/2 Snaps from my Cube IDE:
