How to Transmit Raw Decimal Values (0-255) using UART? Hi I would like to ask if there is any possible alternative to how I'm transmitting values from my STM32F407 Discovery to my PC which receives and buffers the data using a Python program. These are the functions I'm using to transmit my values: void Serial_logi(int val) {
char buffer[10];
itoa(val, buffer, 10);
Serial_log(&buffer[0]);
}
void Serial_log(char *s) {
while (*s) {
while (USART_GetFlagStatus(USART2, USART_FLAG_TXE) == RESET)
; // Wait for Empty
USART_SendData(USART2, *s++); // Send Char
}
} The current implementation converts the decimal value which I wish to transmit, val (0-255) into a string of characters, and then transmits the string character by character. The problem with this implementation is that when I use my Python program to receive the data it does not store it as I want. For example, when I transmit the value 255, instead of storing the first byte as 255, it stores 50 as the first byte because the ASCII value of 2 is 50, a
