CH55x serial debugging adapter
The WCH CH55x series of MCUs are 8bit 89C51 core microcontrollers well equipped with peripherals such as UART modules, PWM modules, general purpose timers, touch modules and SPI modules . Those MCUs lack debug unit, such as JTAG or SWD, thus debugging is only possible with printf style serial debugging.
deBug is a open source software and open source hardware serial debugging solution for the low cost WCH CH55x MCUs. The deBug project provides software and hardware that enable serial, printf style debugging for CH551, CH552 and CH554 MCUs.
