An all-in-one debugger of 8-bit microcontroller with high transfer speed
An all-in-one debugger for 8-bit microcontrollers is developed, which supports three important modes, namely, boundary scan mode, programming mode, and debugging mode. Its transfer speed is higher than some other protocols. Its interface is based on IEEE Std 1149.1-2001 [1] to simplify hardware connection. The system is implemented and tested successfully on a Field Programmable Gate Array (FPGA).
