GPDMA with ADC with multiple channels
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...
Resolved! FreeRTOS xTaskGetTickCount() erroneously skips ahead
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...
Boot in dualcore micro
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...
Resolved! Nucleo-H745ZI - USART via ST-LINK
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...
Resolved! STM32G0x Series Filter downcounter on External Clock Source for Advanced Control Timer 1 (TIM1)
Hi, I am using an event as an external clock input into the Advanced Control Timer (TIM1) on a STM32G0x series MCU. For my application it will be nice to low pass filter the signal using the internal "Filter Downcounter" in the chip. I don't unders...
How to perform continuous sending and reading with DMA ?
Hello,I looked at an example of DMA on CubeMX and I got this code : /* Infinite loop */ while (1) { /* USER CODE END WHILE */ /* USER CODE BEGIN 3 */ if (transferErrorDetected == 1) { /* Toggle LED4 with a period of 200 m...
Timer in one pulse mode
HiI have a trigger ( the pink trace) who triggers one delay of 200µs with the help of the timer 3 ( a channel toggles each event, the red trace) . A IT is also generated . Another channel of this timer 3 is used to trigger a one pulse mode pwm with a...
Resolved! Nucleo STM32L432KC ADC + DMA circular buffer, slower than expected?
I want to take readings from one ADC channel continually and use DMA to store them in a circular buffer. I do have working code which does this, see link below. However, the sampling happens more slowly than I expected.My question is about the rate a...
