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...
Query: STM32F4 programming with USB
I can program my bespoke board using a repurposed USB port. It would normally be used by a mouse.I was under the impression that if I powered up the board with BOOT0 pin held high the MCU would be in a state to connect to USB and do it's enumeration....
