Hi , I want to use the 16F877 for a project. Programming it with the DIY96 and P16Pro seems to work (having modified the device.ini), but my CCS Compiler doesn't support the 16F877. Actually it doesn't even support the 16C77 which seems the closest match. I thought of compiling programs for the 16C74 and try to use this ones. When I load my .hex to the P16Pro , the programmer changes the PIC TYPE to the one, used in the C-Code. If I Change the Device type for being able to program, the memory is being cleared. Can anybody tell me what would be the best(cheapest) way to solve this. Can I add the 16F877 manually to my CCS Compiler?
