Dear experts, A question in relation to OB behavior discussed this thread: https://community.st.com/t5/stm32-mcus-embedded-software/stm32-is-getting-stuck-frozen-and-enables-read-out-protection-at/td-p/615228Is there documentation or App note that ex...
Hi , Is there an automatic calibration routine for the STM32L471RGT6 ADC? If there isn't can someone point me to example code on how to read the internal reference (or some other approach) so I can write code to perform calibration. Thank you very mu...
I read the messages in here about wrong temperature values including code examples, but still getting wrong values:I need to measure the internal CPU temperature sensor from the STM32H743XIH6. I activated the ADC3 using STM32CUBEMX (V. 6.9.2) and sel...
Hi people,I am looking for a help pleaseI am working on a boosting up a voltage and works in a closed control if it exceeds the Max_UC_volt the duty cycle should vary..void run_ucboost(void) { uint16_t mainsfail=1; uint16_t uctimer = 0; uint16_t ...
Good afternoon, Please provide the ECCN number, or Export Classification Number for STM32F207IGT6 Thank you,Ron Simpson
Hi,I am trying to setup GPDMA with ADC with multiple channels on the Nucleo-H563ZI. The DMA should fill a buffer of the length of number of channels in a circular fashion, such that one entry in the buffer array always contains data of the same ADC c...
xTaskGetTickCount() erroneously skips ahead after every 65536 ticks. So when calculating timing using values returned by xTaskGetTickCount(), there are problems! vTaskDelay() has no problems. The problem is with xTaskGetTickCount()... For example:Cod...
Hello everyone,I'm seeking guidance on creating a custom dual-core boot using only an external flash.Previously, I managed to accomplish this for a single-core microcontroller, with the bootloader residing in the internal flash while other code (main...
Hi there,I’m trying to compile a project using the STM32H743ZI2 Nucleo board with STM32CUBE Framework with FreeRTOS with PlatformIO.The project can be found here:Zafeer_FreeRTOSFromGroundUp/PlatformIO/17_WorkingWithQueueSets at main · ZafeerAbbasi/Za...
Using a Nucleo-H745ZI, board revision D-01.According to rev. 5 of UM2408 "User Manual STM32H7 Nucleo-144 boards (MB1363)"USART3 is available via ST_Link. Table 12 lists the config for the virtual com port as the default configHowever, my board had SB...
