STM32 USART variable strings - best solution
Показать описание
Three examples for receiving variable length and structure strings, using the USART of a Cortex M4 microcontroller with interrupts are shown. A TTL-USART converter (CH340 or FTDI232) is connected between the microcontroller and a PC. Terminator characters are used to separate the strings and sub-strings. Numeric strings are automatically converted to integers, and general sub-strings are separated. We illustrate for 115200,n,8,1. No handshaking or another constraint is needed. A large range of applications may use this technique.
