The number of ADC channels in the spec sheet for STM32H753VIH6 is 36 ADC but I realized that in the STM32cubeMX I only can set 16 pins for ADC. How can I use 36 ADC all for individual channel measurement?
After setting up the environment regarding the description (st.com/resource/en/application_note/dm00354244-stm32-microcontroller-debug-toolbox-stmicroelectronics.pdf) it is still not working. Build is OK.Download OK.OCD starts.The getchar() function ...
I am using STM32F103(Bluepill). Since I am not able to load program to the controller through ST-LINK V2 programmer, so not able debug the code. I am loading the program through UART(USB-TTL)I want to know if there is a way to debug the code using U...
I'm trying to figure out if an A-B memory schema on a microcontroller is feasible. Right now I have a bootloader and an application. I basically want to duplicate the application onto two sections of memory: A and B. This way I can receive a firmware...
I'm using STM32H753 eval board and trying to implement memory tests like data, address pins short, memory cell corrupted etc. on this eval baord there is MT28EW128ABA1LPC-0SIT.for testing address pins short detection I've shorted A4 and A5 pins but H...
I'm having trouble reliably sending CAN messages using the HAL functions (STM32CubeIde) in the way I found in some examples. In those, a message is sent by calling HAL_CAN_AddTxMessage(), but for me that causes nothing to be sent unless I manually cl...
I'm requesting the microcontroller to send data to the PC for every 1.1~1.3 ms through BLE using ACI_GATT_UPDATE_CHAR,However, I'm not sure it is fine because the BLE connection event happens every 7.5 ms.What happens microcontroller and PC In this c...
Hello.There is a board with 2 stm32 MCU, one of them is stm32l452. I need to upload a firmware to stm32l452 using system boot. When it starts in system boot mode, second MCU sends 0x7F waiting acknowlenge byte (0x79) but there isn't a responce. After...
Will a voltage divider and a Zener diode pretty much suffice or will galvanic separation be necessary? Does anyone know/have an out-of-the-box solution?Thanks,Mike
