Regarding this section of code, There is no manual which describes this firmware... However this is what it does
This RD_POT value comes from the PC. When the PC software wants to get the A/D result, it will send out CMD RD_POT to USB device, the USB device will do the A/D convert and send the result back to PC.Code:case RD_POT: // Comes from PC Software ReadPOT(); dataPacket._byte[1] = ADRESL; dataPacket._byte[2] = ADRESH; counter=0x03; break;
The .GO Member and .NOT_DONE member is defined in the header file "C:\mcc18\h\p18F4550.h"
which i have included in the code below ( I have highlighted the where ADRESL and ADRESH occur )
But i am not sure how this helps me? What do i need to look for?Code:/*------------------------------------------------------------------------- * $Id: p18f4550.h,v 1.7.12.1 2005/10/11 01:56:23 curtiss Exp $ * MPLAB-Cxx PIC18F4550 processor header * * (c) Copyright 1999-2005 Microchip Technology, All rights reserved *-------------------------------------------------------------------------*/ #ifndef __18F4550_H #define __18F4550_H extern volatile near unsigned char SPPDATA;
