Good afternoon, I have a question regarding the best strategy to follow on how to measure multiple channels with the ADC (triggered with timer) and map them to the DMA. I have followed the project called ADC_DMA_Transfer that can be found in the Pro...
Hello,I am using a STM32H733VGT on a custom design board. On a fresh project in CubeMX, I tried to activate data cache but the autogenerated code crashes at SCB_EnableDCache(); . (nothing has been activated on the CubeMX, just the external crystal a...
Hi There,I have setup TIMER4 on STM32G484 device for overflow event and enabled interrupt for events. Everything works fine and as expected with correct fire time if I RESET the CNT register in the ISR. However, if I do not, it seems to do some level...
Hi,When HAL_Uart_errorhandler is triggered, how can we check if the trigger is for reception or transmission?
Hi I am using STM32F407 DISCOVERY BOARD and I am able to make the board change to boot mode using a another controller.After boot mode change over I need to program the memory of STM32F407 DISCOVERY BOARD by UART communication.Here I am unable to get...
Hi, I'm trying to do an external loader according ST's MOOC and this forum https://community.st.com/t5/stm32-mcus-products/stm32h5-external-loader/td-p/601134.My code pass on all ST's tests of memory, but when I generate a stldr it does not read on c...
I am currently using stm32f407 with FreeRTOS as operating system in MDK IDE. Recently, When I added a new function ( The new function is ospf routing algorithm, and it is very complex and involves many files ) to my project, I began to encounter hard...
This is mostly a post to help people who try to google this later since I couldn't find anything. If you look at AN2606 table 197, it lists the minimum startup time for the bootloader on a bunch of different STM32 microcontrollers. For some reason, j...
Recently, I have been working on a project that intends to utilize the v9.x bootloader on an STM32L471VGT6 through the SPI 2 port. When utilizing the write memory command, I would find that the STM32L4 would occasionally have 0xFFFFFFFFFFFFFFFF writt...
Hello,I am currently working on sensorless PI control for a BLDC motor, and I am using the STM32F303ZE MCU for this project.In sensorless BLDC motor control, the motor must transition to the next commutation step 30 electrical degrees after the zero-...
