Rules for this thread...

1. This thread is currently intended for P2 Drivers and/or Tools that can be used in the development of P2 Programs on the DE0 & DE2 P2 emulations prior to the release of the P2.
   • What will happen after release of the P2 is not known at this time.
2. Only 1 post per Driver or Tool which may/should include:
   • Description of the Driver or Tool.
   • Link to the thread(s) where discussion about this driver/tool is taking place
   • MUST INCLUDE: "Please use this link to the appropriate thread for any questions or discussions about this Driver/Tool."
   • Attached Driver or Tool and any demonstration code or instructions (optional but preferred)

Thanks for your co-operation.

DRIVER:

SerialDebugger

DESCRIPTION:

1. LMM execution loop for LMM code
2. Hub based LMM code for SerialDebugger
3. This debugger currently has the following call options:
   • TX - send a long as character(s), lower byte first. ($00 from the top byte down are ignored)
   • ASCII - send TX character(s) where control/invisible characters $00..$1F and $7F..$FF will be output as "<xx>" where xx=hex.
   • HEX - send a long as HEX with using the number of digits specified (8..1). Optional modifiers are:
     • REVERSED - the long is sent lower byte first
     • SPACE - a space is added between hex character pairs
   • STRING - sends a string of TX characters and is terminated by a $00 (nul)
   • DUMP - sends 4 longs as a string of spaced hex characters followed by ASCII characters where control/invisible are sent as "."
     • Modifiers are COG and HUB where HUB is the default.
     • Lower byte is sent first (HEX REVERSED) as would be normal when dumping memory using byte mode.
   • RX - waits to receive a character. Half duplex is used, so any characters received when not waiting in this loop are ignored.
4. Does all this from your program's cog:
   • Uses the same cog as the users program. The user calls the debugger to send/receive and at the end, the debugger returns to the users program.
   • Uses a small cog footprint
   • Uses minimal P2 resources
   • Uses hub to store the LMM debug code
   • Excellent for debugging P2 programs using the single cog DE0 emulator
   • LMM mode is a method where each instruction is copied from hub to cog to be executed in an LMM execution loop (devised by Bill Henning for the P1).
