General Information :
All zip files are build with the same principle :
- the schematic in PDF format
- a zip file with CADCAM text in the name, this file can be send as it is to a PCB manufactuer.
	some suggestions without and personnal interest in any mentioned company :
		PCBWAY
		JLC PCB
	price is around 5$ for 5 pcb 100x100mm (minimum order) + freight charges.
- all software files, in C code. The compilers used are CC5X or CC8E, MPLAB version 8.92.
  Some soft compile with the demo compiler, but most of them need a licence version.
- a doc repertory contains all sort of other files they can include :
	an excel file often including menus structure
	some stl files to build the case with 3d printer.
	pdf file for front panel marqing
		I paint (spray) a metallic color (the chrome is nice) on the front panel
		I print the file on a transparent film sticker, stick it on front panel and cut the 
		openings
	any other file that was usefull
	a bootloader hex file is also often included.
- a bootloader zip file is also availble for bootloader utilities. 
	This code must be programmed once in the pic device using a dedicated programmer (e.g. pickit), 
	later on the op firmware can be uploaded using usb or serial protocol the reset button must be pressed with dedicated button.
	Release reset first.
	For the serial protocol a special hard and soft is available separately.
	The pc aps for usb uploaders use one of following Microchip soft :
		for MPHPUSB.hex you must use PDFSUSB  
		otherwise the HID bootloader.
A return message in case you plan or have completed one of these projects is appeciated.

Sorry for having a lot of french and english mixed, will try to improve from time to time.
