I am building an CAN system which includes sensor modules and actuator modules. There is 1 center MCU which control/communicate with all modules via can bus. I also want to update firmware for each module from that center MCU through CAN bus. Which h...
I used related functions of HAL in Keil to program option bytes. I cannot connect to MCU again after I write option bytes. I think MCU is locked , and I've tried two MCUs , both is locked, How can I unlock this MCU? It's external boot pin seems usele...
Hello, I would like to ask you, if there is any way to calculate the value of sense capacity? I am using TSC peripheral on STM32L083 and I am trying to interpret the output value from TSC. I've read every application note for TSC, and I didn't find ...
Hello,I have written UART+DMA receiving code under CubeIDE. After few days, receive process stops receiving characters from UART. I can confirm with the oscilloscope that the GSM module is responding properly to At queries, but nothing is received in...
Hi , I am trying to develop the external loader for W25Q128JV flash interfaced with STM32h750vb through QSPI. I have tested each function for its operation in STM32CUBE_IDE.But i am not able to get the External loader to work it cannot read write or ...
Hi,I have my design using STM32H750 (which does not matter in fact it is general question) and I uses Yamaichi microSD connector hat does not have card detect pin. In single data mode, I use one of the SD-Card pins to detect card bit obviously I cann...

Posted on April 19, 2018 at 20:16Hi,Where is the STM32H7 DMA request mapping table documented ? we want to use DMA on USART1 RX and TX.In STm32Cube for STM32H7, example UART_HyperTerminal_DMA , the DMA mappings are:/* Definition for USARTx's DMA */&...
Hello,I'm using stm32f070c6. When pulling up 'BOOT0' with 10kΩ to VCC(3.3V) , I'm able to run my code on my custom designed board using STM32CUBEIDE.When I press RST or power cycle board, nothing runs. This is expected right? Since I'm in Bootloader ...
Hi,I am using STM32L07xxxI want to use USART4 and USART 5 So i generated code using STM32CUBEMXBelow is generated code for interruptvoid USART4_5_IRQHandler(void) { /* USER CODE BEGIN USART4_5_IRQn 0 */ /* USER CODE END USART4_5_IRQn 0 */ HAL...
