About
S1debug is a debug console running on the host (PC), much more then s1giveio. But instead using the USB to controll the device, this one uses a self-build Debug interface attached to the mp3 players I²C bus. To drive this interface on the client side, a s1Debug API is needed to be present in memory.
The debug console provides following features:
- display debug output (putch, puts, ...)
- single command tracing/stepping
- reading/writing registers/ports/memory
- support for breakpoints
- upload/execute code
- disassembler

Run it
Before you could use the software part you'll need to build a Debug interface and connect it between your pc's parallel port and the s1mp3 player. If you wish you can buy a ready-mounted pcb board from Wire at his site: (buy now). If the hardware works (red light on) then upload the client part to your mp3 player. For this reason you could use s1giveio and upload the \s1debug\client\test.bin file from the client folder of the archive. Finally run the \s1debug\host\s1debug\release\s1debug.exe (win32 only) or compile and run the code inside the host folder for any target system you want.
