I'm using Dynamicgrapgh widget in TouchGFX to represent the sensor values graphically, i want to display the X and Y axis labels. I'm unable to get the labels on display UI even though i have enables Horizontal and vertical axis labels. Also how to write a function to update the sensor values on graph. Suggest me a solution

Hi I am trying to implement a custom ISO/IEC 15693 command called "Fast Read Unlimited Blocks" command for the Fujitsu Tag MB89R118C (attached the datasheet). This command allows reading all 256 memory block or 2048 bytes on the Tag's memory in one transaction. I have created a function `rfalMb89r118cPollerFastReadMultipleBlocksUnlimited` to implement the Fast Read Unlimited Block Command using the rfal library and the `rfalNfcvPollerTransceiveReq` function call. The implementation and use of `rfalMb89r118cPollerFastReadMultipleBlocksUnlimited` is as follows:Implementation of `rfalMb89r118cPollerFastReadMultipleBlocksUnlimited`:// Fast read multiple blocks unlimitedReturnCode rfalMb89r118cPollerFastReadMultipleBlocksUnlimited(    uint8_t flags, const uint8_t* uid, uint8_t firstBlockNum,    uint8_t numOfBlocks, uint8_t* rxBuf, uint16_t rxBufLen, uint16_t*&nbs

Posted on June 12, 2018 at 10:21I am trying to interface with the ST25R3911B-DISCO board via UART. Basically I want to send commands to the reader and then receive the response via the provided UART. I am planning on connecting the ST25R3911B-DISCO board to an external MCU and thus want to use UART as the interfacing standard between the two.I am struggling to find documentation on on how this is possible via the boards UART. Where can one find out what baud rate to use? And Is there a specific mode in which the ST25R3911B-DISCO board must be in for communication via UART to work? Also what commands are available and what type of responses can be expected from the boards UART.Any documentation, assistance or pointers to help would be greatly appreciated.The tag I have is the stock standard ST25TA64K that came with the ST25R3911B-DISCO kit.#st25r3911b-disco #i2c-and-uart #ndef-st25ta64k

Hello. I have a circuit containing notably: (i) MCU pin PA2 connected to both a ULN2003 transistor-array input and a 10k pulldown resistor and (ii) the corresponding output of the ULN2003 is connected to a small beeper GND. In theory, this circuit is supposed to maintain the transistor input at logical zero when the MCU pin is floating, hence preventing the beeper from ever turning on unless it is desired. I noticed the following:When powering on a board with a MCU that was never flashed, my beeper always turns on. When I check the MCU pin PA2, I read 3.3V. This 3.3V appears despite the 10K pulldown resistor on it, so we can be sure that the pin PA2 at this point must be configured as output, with logical 1 set.If I flash a program that does nothing (simple infinite "for" loop just after the main entry point), then doing a power cycle, the beeper no longer turns on, and the MCU pin now reads 0.If I erase the whole MCU and do a power cycle again, then the beeper turns on.The datasheet f

I have bought the SPC582B-DIS EVB from Mouser. (SPC582B-DIS STMicroelectronics | Mouser Korea, Republic of)However, this product doesn't work normally. I think there is a problem with FDTI Dirver chip as below.So, I asked Mouser for a refund. However, they asked me to confirm from ST that there was a problem with the product. Please, help me for a refund. Thank you.

Hello,I have the RTC set for a 1 Hz interrupt. I have buttons, that when pressed, trigger a rising edge interrupt. The interrupts work fine except that when I call my button handling routine the RTC interrupts are blocked. They remain block until the button is released. I wouldn't thinkit would behave this way for an edge triggered interrupt. Here is the gpio interrupt handler in stm32l0xx_it.c: * @brief This function handles EXTI line 4 to 15 interrupts. */ void EXTI4_15_IRQHandler(void) { /* USER CODE BEGIN EXTI4_15_IRQn 0 */   /* USER CODE END EXTI4_15_IRQn 0 */ HAL_GPIO_EXTI_IRQHandler(GPIO_PIN_9); HAL_GPIO_EXTI_IRQHandler(GPIO_PIN_10); HAL_GPIO_EXTI_IRQHandler(GPIO_PIN_11); HAL_GPIO_EXTI_IRQHandler(GPIO_PIN_12); /* USER CODE BEGIN EXTI4_15_IRQn 1 */   /* USER CODE END EXTI4_15_IRQn 1 */ }These call this handler in stm32l0xxhal_gpio.c * @brief This function handles EXTI interrupt request. * @param GPIO_Pin Specifies the pins connected to the EXTI line. * @retva

Hello,if try to reproduce the STM32H743-EVAL board, is it possible to program its NOR FLASH (MT25TL01GHBB8ESF) if i use the existing external loader? I think the answer is yes. However, i can put in my board just the STM32H743II MCU instead of the STM32H743XI present in the original board.Before i try to do this, will the programmer returns error if i try to program my custom board?

Hello, guys.I need to improve one old project. There is no free pins on MCU left, except PC13-PC15 and I need three external interrupts. Code with initialization for making PC13-PC15 as inputs lower. I do not use LSE or RTC anyway.For PC13 all works fine, interrupt works as desired. In IRQ routine flags are cleared as expected. But after first change of pin state for PC14 or PC15 interrupt keeps fire, as if corresponding pending bits are not cleared in IRQ handler. In project I used StdPeriphLib v.3.5.0. I checked, there is no mistakes on low level acces to registers in functiones and definings of corresponding setting bits. Also there is no external noise on PC14 and PC15. To be sure about this, I've tryde different external "strong pullups", also oscilloscope shows no noises on this pins. VBAT pin externally connected to VDD with a 100nF capacitor, as said in reference manual. Also external impulses are coming with clear fronts, there are no parasitic capacitance or connections on th

How to change background color of the elements that I have selected but later removed that selection in dark theme? If I select CDC_Receive_FS, for example, and it is green in dark theme, after I continue to do anything the background of all instances of CDC_Receive_FS are becoming freaking acid. I can't even read this.Here is a screenshot

I create a project on stm32f429zi nucleo, add LTDC, Touch GFX, CRC. I configure everything, add a BOX and a button. There are 3 errors when compiling. I tried it on different versions of CubeIDE and TouchGFX and different controllers. The only thing is that the errors change. On older versions, there are errors with the stack.make -j8 all Error: Cannot find the specified linker script.

I can successfully program a STM32L082 over USB when using STM32_Programmer_CLI.exe but not using the GUI. I can see the device under USB but I get "Error: Data read failed" followed by "Warning: Connection to device 0x447 is lost" when clicking the connect button. I have previously had no problems using this method on the same board (possibly with an earlier version of STM32 Programmer).

I'm looking for any potential vendors where I could host a cloud VM for doing automated STM32 builds coupled with some infrastructure for managing releases? Any recommendations?

Hello community, I am trying to debug my STM32f103C8T6 bluepill board (probably using fake chip) on STM32CubeIDE but there is something goes wrong about both GDB and Local Server. In debug configuration, When I set debug probe to "ST-Link GDB Server", I got "Failed to start GDB server Error in initializing ST-LINK device."When I set debug probe to "ST-LINK (Open OCD)", I got "localhost:3333: The system tried to join a drive to a directory on a joined drive." I programmed my board on Keilu5 without any problem. Actually I have to press reset button after flashing even I select "reset and run". this is maybe an important issue. Also, debugging on Keilu5 working bugy on my board. I hope this information bring a solution to your mind. System;Windows 10,8 GB RAMIntel i7 6700HQGTX 950m   Regards. Baki ALMACIHacettepe University Electrical and Electronics Engineering.

the noise intensity level print on serially on monitor . from this the threshold has to be set to detect pleasant noise or harmful noises for further coding and analysis.I am stuck at a point in PCM audio data out conversion to dB i.e noise level .Below is a image attached on how I am getting the PCM values in buffer. And I am not sure how to validate whether this is correct or wrong.? and after this if any voice or variations in the mic should be showing alterations in the noise level intensity printing serially.I am a beginner with audio mems mic and audio processing.Please help .this project is on urgent requirement.Thanks in advance.

I mean, I setup TIM1 CH1 as output PWM, One pulse mode, but I need to trigger it by my codesfor example which register should be set to high or low to generate a pulse on TIM1 CH1

Hello! I'm writing data to flash and ran into an odd anomaly where the data is erasing itself on reboot. I have one program writing data to flash and another reading and it keeps reading back nothing. I ended up writing the data using one program and then reading the data using the STM32CubeProgrammer. First read shows my data. When I disconnect and reconnect, it's all gone again. My current code is fairly simple. I have a flash location with 10 pages set aside:/* Memories definition */ MEMORY { RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 40K FLASH (rx) : ORIGIN = 0x8000000, LENGTH = 106k FLAG_VAR (rx) : ORIGIN = 0x8015800, LENGTH = 2k LOC_VAR (rx) : ORIGIN = 0x8016000, LENGTH = 20k }I am currently only using 1 page for testing purposes though. I am effectively erasing the flash and then counting up in the byteArray by 1, then writing 2048 bytes (one page). It seems to be working ok (as I mentioned, it's writing correctly, it's just erasing it a second time). Unfortunately, I'm

Hi,The STM32H753 datasheet is missing the R_ADC value.On the caption of Figure 92 (p. 284) it says that R_ADC value can be found in table 183, but the value is not there.Does anybody have this value? Did the value change between Rev.Y and Rev.V?Thanks,Yan

Hi together, I’m trying to start a new project using STM32G031. The final decision of the MCU isn’t made yet and therefore I’m currently testing the possibilities with the Nucleo STM32G031K8 board. I’m using the onboards USB debug interface. I start a new Keil uVision project and everything work as expected until I add WFI() at the end of my main loop. After adding it, I start a debug session and everything is fine. But after leaving this first debug session and trying to start it second one again, I got the error message “Invalid ROM table�?.From that point it’s not possible to debug or even flash the MCU using uVision. I have to copy a hex file (strange that it’s the same source) using the storage bootloader and after that it’s possible to start a new debug session. Unfortunately with the same result, that after leaving it and trying to debug again, I got this error message. I’m checked all ideas and tips I found here, check different “Connect and Reset Options�? because this lo

I have the latest version of the ST BLE Sensor on Android 9. I changed the firmware to test out the Cube samples. I can't go back to the Pro mode now!!

How can I set in Keil MDK, used to stored some parameters such as soft version,manufacture date and so on at a block of（such as a page） STM32G4‘s Flash memory， thanks.

I'm using stm32h745. CubeMX Clock Configuration shows APB1 and APB2 clocks are 120MHz, and APB1 and APB2 Timer Clocks are 240MHz (2 x 120). When i call HAL_RCC_GetPCLK2Freq(), HAL_RCC_GetPCLK1Freq(), they indeed return 120MHz. I use general purpose timer to generate PWM based on timer clock freq of 240MHz. PWM signal freq is way off. For example i use timer clock of 240MHz to compute a 53KHz PWM; scope shows 16.95KHz PWM instead. This is the same code used to calculate PWM freq, from timer clk freq, used on other projects so i know it works correctly. It seems the timer clk is not 240MHz but something else. If someone has knowledge of stm32h7 timer clock freq, please let me know.

Hello,I need your help to recognize my issue correctly, please help me,background:I am having trouble using the stm32l053RB NUCLEO development board for USB protocol parsing.issue：When​ using timer to generate PWM, once the USB receive data is configured, the PWM waveform frequency will be greatly reduced.Also when using the timer to generate a timed interrupt, once the USB work is configured, the CNT data will be stuck, and the timer will stop unless the USB is reset.I have tried all the timers of this chip and will have the same problem.Why is this happening, does USB work affect the clock of TIMER?​ if you can help to solve issue or give any advice, I am very thankful for your kindness in advance.Thanks.​my email is jysong@mindpointeye.com
