Ask questions, find answers, and share insights on STM32 products and their technical features.
I would like to share a bug I encountered and how to fix it:I am using an STM32L151, the goal is to set it into SLEEP mode and wake it up using a UART receive interrupt while debugging. All configurations to pins, registers and interrupts are made co...
Hi,I know the question has been asked before, and there is some information (to some extent) on the internet, though I cannot seem to make it happen. My question is:How can I use print() for debugging purpose? I have an UART peripheral up and running...
Using STM32U599 Hex SPI connect with PSRAM(256MBits， 32 MBytes), configure Hex SPI as QSPI, command/address is 4 Lines and 32 Bits. Only use IO0/1/2/3 and CS/CLK and IO15(used to make PSRAM enter OSPI or QSPI mode)Now, we could read/write PSRAM Mode ...
Hello there!I am trying to use some STM32F103RB Nucleoboards and some MCP2551 chips to make a CAN-bus. I got this problem where I can make it work in loop-back mode, but I cannot send from one board, to another one. I know the Circuit is stable and c...
Hello everyone,I successfully used USART1 and USART3 in my application. However, when trying to use USART4, Rx is working but not Tx. The idle signal stays at 0V all the time. Here is what I already check:UART initstatic void MX_USART4_UART_Init(void...
Hi... Greetings... We're planning to use STM32H503 MCU in our application. To brief about our application, we've a parallel RTC IC which has gone EOL. This RTC receives commands from the motherboard MCU. So, we're mimicking the RTC's functionality u...
Hello, I want to communicate with a PC using FDCAN with the Nucleo-H743ZI2 development board. According to the information I found,the STM32 board requires a transceiver for CAN communication,and since the PC does not have a CAN port, a CAN to USB in...
Dear all,i have a custom pcb with a STM32H753XIHx.I want to use CAN1 Interface to receive PDO and SDOs (Baudrate: 125k, CANopen).My receive routine looks like this: // CAN 1 receive interrupt callback void HAL_FDCAN_RxFifo0Callback(FDCAN_HandleTypeDe...
I am using ADC channel with DMA to get linear hall sensor data ,its giving bur after some time adc pin not working. but same code working with another board, what can be problem.
Hello,I have an STM32F107 microcontroller that uses DMA and USART to receive 250 bytes every 10 ms. The RTOS tick is 1 kHz, so osDelay(1) results in a delay of about 1 ms.The sender transmits 200 bytes every 5 ms, and during this phase, it is not cri...
