Receiving incorrect responses from STM32G071RB with 9600 baudrate
Hello!I am very new to STM32 boards and MCU-s overall. I am using a Nucleo-G071RB and I implemeted this Modbus library: /ceremcem/modbus_lib. For testing I use Comtest Pro. The code was working without issues on a Nucleo-F446RE. On Nucleo-F030R8 I am...
ADC DMA data order sometimes is wrong STM32F303RBT6
I may have seen other posts discussing this topic, but neither of them helped with this. Does the ADC in the buffer we send to the DMA put the data in order? or is some bug in the code? I'm reading for 3 analog values and sometimes, it works correspo...
Hot to get the time a input is high
Hi all,i am new to the STM32-stuff and i have little project. Actually i need a tool to test camera shutters from 30s to 1/8000s. I have desiged a kind of sensor board in Kicad. I link to use two sensor for horizontal traveling shutter and two for ve...
Can ST please match signals names used in RM and DS?
I even looked into the .xml whith CubeMX uses, and cannot see ADC1_INNx/INPx for 'L4 either.JW
Resolved! Alter CAN Message Data, Array to Int
Hello,This is a mixture of a C question and a CAN communication question, as I want to find the simplest solution for what I'm trying to do. I have an 8 byte CAN message that I successfully receive and store in an array (uint8_t RXData[8]). I am send...
Resolved! HAL_UART_Transmit() with HAL_UART_Receive_IT() fails if RX when TX not completed.
I used to send AT command to a module with HAL_UART_Transmit():void send_uart(char * buffer) { uint16_t buffer_size = strlen(buffer); uint8_t CRLFbuff[] = "\r\n"; HAL_UART_Transmit(&hlpuart1, CRLFbuff, 2, 0xFF); // ok HAL_UART_Transmit(&hlpuart1...
STM32F405/407/415/417 DBGMCU_IDCODE.REV_ID
Can please anybody who has any of the above mcu, post here content of DBGMCU_IDCODE.REV_ID together with the revision number/letter marked on the package?I suspect that table in RM0090 is not entirely correct. Rev.Y is historically older than Rev.2 a...
