Title: Pendant/control panel with PIC 18f4221.
Post by: PerE on August 05, 2007, 06:57:17 AM

Hello all.
I want to build my own pendant/control panel for my router and i am going to use a PIC 18f4221 microcontroller. I want to learn to program this unit and use it for controll Mach3. Has anybody done this and what are the hints ? What do i have to think about when i am doing this ? Be gentle to me because it´s hard to learn an old dog (46year) to sit.  ;)

You might want to start out with one of these as it will give you easy ModBus interface and a few people here on the forum can give you some tips,  I'm still learning this CubLoc thing.   It is very easy to use even for me:)

Thank you but i already have my processor (PIC 18F4221) and i want to program that one for my application.
I want to learn ASM (assembler) and i want to build my own pendant/control panel.

If you have never programmed before, youre up for a steep climb. I use PICS for many years, from 8 bit to 16 bit dsPICS. I would suggest you purchase a demo board (PICDEM2 PLUS) and an ICD2 from Microchip, but if the cash is low, there is another way. I implement the modbus on the dsPIC30F6014A and the dsPIC33 range which gives 40MIPS. The modbus is advanced programming, you need to implement CRC (Cyclic redundancy Check).

Thanks for the replies. I have purchased a WISP628 and i have already started to program the unit.  ;)
