I am trying to create a Client that communicates via Ethernet on the PHY LAN8720 chip. The program has an error that does not run automatically when the board is powered on or the chip is reset. If I use debug, I have to press RUN several times to be...
Hi,I have connected a MAX-M10M module to an STM32H7 MCU ( it's custom board) by UART port. I am able to send data to GPS module and also receive config data of it but not able to receive NMEA packets. I only receive the first byte and then the HAL_...
Hi, I have some code running on an STM32G431 that does a loop in which it reads on a pin on port GPIOB, shifts the value and writes the result on GPIOC. I have trouble really understanding the timing I see on the oscilloscope. The code is: ldr ...
Hello community! What are the simplest ST uC with CAN feature? Yours suggestions will be welcome! Many thanks and Regards!
Hello, I currently have an IAR Embedded Workbench 8.22 dongle license, but this version does not support STM32G4 since the MCU series was introduced later. Upgrading to a newer IAR version is not an option due to budget constraints, but functional sa...
I searched about STM32H563 maximum current consumption of AD converter when run mode on datasheet and reference manual.I could't find AD converter's maximum current consumpsion on datasheet and reference manual.I want to consider external LDO for VDD...
I am trying to implement authenticate a device from flashing new code from unauthorized user using ST-SAFEA1. only a valid user can flash new code in DFU mode using USB peripheral.Issue is I am can't be able to authenticate the device and generate pu...
Hello, trying to send array below. The '0x00' part is not received in terminal, see image below. char binary_data[] = {0x01, 0x02, 0xAB, 0x00, 0xCD}; HAL_UART_Transmit(&huart5, binary_data, sizeof(binary_data), HAL_MAX_DELAY); How can I get this t...
Hello guys, recently I designed a PCB board using STM32H743IIT6 and I encounter a problem when I try to run code in sdram. The details are described as below.question: I have a demand jumping to run a user program(function) in the sdram. B...
Hi, I have developed a circuit using STM32h755zi, i am sending some serial data from a custom board to PC using USB CDC class. It works fine when i use a Type C to Type A cable but when i try to run the board using a Type C to Type C cable it only ru...
