Pic18F4520 (by Frank McAlinden)
Hi Guys , im currently working on a project which uses the pic16F877. I think i may run out of program memory and noticed that the PIC18F4520 can be used ,so bought a few and when i went to compile it asks me to use the HiTech C compile option.Im not a C Programmer and was wondering do i have any simple options to use this chip...

There is no other method than using the Hitec C compiler for the PIC18F4520.

Hi Frank

You just need to install the compiler so that ldmicro can use it
to build your hex file ; no need to program in C.

Download last ldmicro32 files (zip version 5.5, not 6.0) on my github:


Download HTC (Hitech) C compiler on the same page and then read HowTo-PIC18 file in zip archive to install.

Post here if you need more help.
