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 ...
In our project I use STM32H573VIT6 LDO uC. We have a problem with the PB14 pin. We use 3 pins for LED control (PB10, PB13 and PB14, see photo). The problem with the PB14 is that the LED lights up dimly without code initialization. If PB14 is initiali...
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...
I'm using the stm23F103C8 and I would use the RTC internal cloak/calendar. The program is working fine and I have used the LSE osc (32KHz..) as clock source. I have connected a 3V battery to the VBAT pin. My problem is that the switching off the main...
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.
