Solved

Hi there,I am using a Nucleo H723ZG and my ADC(s) behave weirdly.I need only one ADC, from the datasheet the ADC3 supports 5 MSPS.Since I needed the highest possible sampling rate, I've chosen this one.The data gets collected in one burst of 4096 12-bit samples into a DMA buffer of 16-bit words.On the input I attached a potentiometers wiper for testing, the other ports of the potentiometer are connected to AGND and AVDD on the Nucleo board.Since I've got weird output values, I dumped the first 200 words of the buffer into logs, the logs are attached to this post.The first burst of 4096 samples (adc_3_12_bit_buffer_1st_run.log) shows the expected value (4095) in each sample (except for the first 8), since the potentiometer was set to the full voltage of roughly 3.3V.But without changing anything, the second and following bursts (adc_3_12_bit_buffer_2nd_and_later_runs.log from the 2nd, but the others are similar) show completely different values, where all N samples the values are as exp

i am using one side microcontroller stm32103 which have can1 protocole does this work with othere microcontoller stm32g0b1re which have FDCAN protocol.?does both communicate with each other ?will read and write the data?

Hi,im trying to get this example to work, but it sont compile. The paths for all includes are set up with a link folder in the project.I double checked those, but cant get to the problem.The order is: "main.c -> main.h -> stm32f3xx_hal.h -> HAL_StatusTypeDef HAL_Init(void)" and the file is in "\Drivers\STM32F3xx_HAL_Driver\Inc\stm32f3xx_hal.h" as link in the project and set up as include path (see pictures).Something looks strange, as there are no files shown in "../Core/inc" in picture "strange.jpg".Its Cubde IDE Version: 1.12.0.

I am looking for a full datasheet for ST microcontroller 324BAAP 269-546 9911L V5 MYS 145. Do you know if I can find anywhere or is any way to ask ST to provide this? Thanks in advance for any help.Zygi

I need to fix an audio amplifier that uses a TDA7266M. Unfortunately, I can only find TDA7266 (stereo version) in stores in my city. I compared the pins and it seems that I can use one channel without any modifications. What should I do with a disconnected channel? Is it enough to connect the input via a capacitor to ground?

I have a design that uses and STM32L4 series MCU. The device will be hard to physically access, but has a serial connection to the 'outside' world on UART 4. The board also has a 4 Mbit flash connected to the MCU via (bit-banged) SPI.When I need to update the FW in the MCU I'd like be able to send the binary file down the serial connection, store it in the external SPI flash, verify the download is good, and then copy flash the MCU FLASH so that the next boot up will be with the new FW. Can someone please first verify if this is possible, and second point me to some resources on how to implement it?Thanks!

When reading from the sd card is completed, HAL_SD_RxCpltCallback is executed. But when I use the HAL_Delay() function within the callback, the rest of the code within the callback after that delay doesn't run.Any information about this issue is greatly appreciated.

I looked at the pages for both MCUs side-by-side:https://www.st.com/en/microcontrollers-microprocessors/stm32f407ze.html/https://www.st.com/en/microcontrollers-microprocessors/stm32f407ve.htmlI can detect no difference other than the Z vs. V in the name.What are actual differences?

I already spend many hours trying to figure out why flashing the nucleo does not work.What i found out so far:ST-LINK_gdbserver.exe is not started from IDE. Starting it with the copied commandline, it only works with a port other than the default one. When it is started, the LED of the nucleo starts flashing green/red (!).I can launch stlinkserver and gdb server, so that they are running, but still i got the problem. I already tried many options as openOCD, checking the ST-LINK S/N box and scan inserted a longer number. Also tried all resetbehaviours. Log to file did not create a file from gdb-server and shared ST-LINK did not change the outcome.Changing the frequency did not work either.The firmware of the stlink is V2.J42.M27.Also i updated the firmware to exclude mass storage.stlinkserver is started from the IDE with "-a -p7184".This error message is really lacking with some more details. Maybe there is a log for it somwhere?

Hello!I'm getting the error: INTERNAL ERROR: list index out of range when uploading an onnx model to STM32Cube.AI and run analysis. I would appreciate if anyone could help to figure out what could be the problem? I attach my model below in case someone can help me. Thanks in advance. Regards!

I want to replace STM32L083RZH6 with STM32L083RZH3 and I suppose it's safe, but I cannot find information about the difference in the Datasheet.

I know that "CFG_TASK_SW1_BUTTON_PUSHED_ID" was set in the header file (/app_conf.h), but just set, no morein the Datasheet the button for Nucleo board SW1 connected to a PC4 pin, but in CubeMX for project "p2p_server" I didn't find any mentions about the button SW1 so, How I can in the custom project to set the variable - "CFG_TASK_SW1_BUTTON_PUSHED_ID" for input PC4 or PC5for example, see the code here https://github.com/DavidStdio/STM32WB55_MEMS/blob/3036daab25fe711a5f2f7b37b1537f762bb832ea/Src/p2p_server_app.c

I design a custom board including a stm32wb15ccu where I want to use the I2C bus. I have for SDA and SCL 10k pull up resistors. However when launching i2c the signal of SDA and SCL remain at 3.3V, no bus signal. Hence I could not communicate between the MCU and its slaves. ​pin 5 is SCL and pin 6 is SDA. ​What I did so far to get the cause:Connected an external nucleo to the i2c pin headers , this worked perfectly fine. Resoldered the MCU chip multiple timesDesoldered the pull up resistors, if somewhere 3V3 is shorted to the i2c. What I found interesting when desoldered the pull up resistors the voltage of the ​i2c is still at 0.2V instead of zero.​What I suppose a possible cause:Partly damage of the MCUDesign error, wrong pin selected for I2C on the WB​TThanks in advance for any help

I'm trying to configure the DCMI pheriferal of the STM32F746-Discovery and in AN5020 PDF i find that exist some examples implemented in STM32CubeMx. Where i can find it? I don't find the examples in the STM32Cube examples.Foto of the AN5020 examples:

I am using STM32H503.I want to receive only incoming ids as 0x222 using masking .If set like the code below, IDs other than 0x222 are also entered into the rx callback function. Is there something wrong with the masking process?FDCAN_FilterTypeDef sFilterConfig;   sFilterConfig.IdType = FDCAN_STANDARD_ID; sFilterConfig.FilterIndex = 0; sFilterConfig.FilterType = FDCAN_FILTER_MASK; sFilterConfig.FilterConfig = FDCAN_FILTER_TO_RXFIFO0; sFilterConfig.FilterID1 = 0x222; sFilterConfig.FilterID2 = 0x7FF;   if(HAL_FDCAN_ConfigFilter(&hfdcan1, &sFilterConfig) != HAL_OK) { Error_Handler(); }

Dear, FDCAN does not work.Please advise if there is any problem in the entire code below.The set clock of FDCAN is 48Mhz and each setting is as follows.When the code is executed, Tx is transmitted once every 4 seconds in the while loop.However, if Tx is entered about 4 times, it always falls into Error_Handler.Error returns Error at the bottom of HAL_FDCAN_AddMessageToTxFifoQ function.HAL_StatusTypeDef HAL_FDCAN_AddMessageToTxFifoQ(FDCAN_HandleTypeDef *hfdcan, const FDCAN_TxHeaderTypeDef *pTxHeader,   const uint8_t *pTxData)   {   ///////////////////////////////////////////// Skip   if (hfdcan->State == HAL_FDCAN_STATE_BUSY)   {   /* Check that the Tx FIFO/Queue is not full */   if ((hfdcan->Instance->TXFQS & FDCAN_TXFQS_TFQF) != 0U)   {   /* Update error code */   hfdcan->ErrorCode |= HAL_FDCAN_ERROR_FIFO_FULL;       return HAL_ERROR;   }   ////////////////////////////////////////

I'm wondering whether there is a DMA channel to transfer a received message from the CAN fifo to a memory location. Is it possible at all to get DMA working with the CAN controller?Kind regards,Stefan
