Pinguino with ART2003

Pinguino with ART2003
Hello guys,

At this moment it's only possible to write your bootloader with LVP dissabled. This means you need an extra power source if you want to write the bootloader to your board with an ART2003.

Now if you have an etched ART2003 like me then you would need to redesign your board for an 11V power supply.

If you just pull the PGM pin low then everything works even with LVP enabled. Ok you would loose pin5 of the pinguino program but you still have 16 other pins to work with :p

The problems that I had when I didn't pull PGM low where mostly USB related so if you don't have an interface and just want to work with a simple led program this isn't required.

So when just powered at 5V the device would work perfectly but when connected to USB+ and USB- it would constantly reset and never (ok once if you're lucky but not for long) enter user mode.

After connecting PGM (pin 26) with a 10k resistor to the ground the USB was stable again.

Be aware that this issue is only if you flash your board with LVP enabled (wich is required if you take a simple ART2003!!!!)

I still encounter difficulties with the USB classes in pinguino but I think they're driver related (windows 7 64 bit). I'm going to change my program so it would use CDC. But that is another issue.

I hope by sharing this info more people are able to participate in this great project

Regards

RE: Pinguino with ART2003
Hi @Xumpino
Looks like u know about how to burn a bootloader with ART2003, I just built one using 8 diodes, 1 220R resister and DB25 connector. I cannot get the pic18f4550 recognized by winpic800 V3.59 programmer. It says pic not found so I couldn't burn the bootloader.

Could you please guide me step-by step how to do it ....PLEASE
Also which burning software is the best for burring bootlaoder and which bootloader should I use to get my basic pinguino (18f4550) started with.
Thanx
Mabbo

It is easier to complain than it is to do, but it is better to do than it is to complain.

RE: Pinguino with ART2003
Thanx @regis for the info... its bootloaderV2.12_PIC18Fx550.hex.
Just wanted to know, I just saw that another bootloader of v3 (bootloaderV3.00_PIC18Fx550.hex) is also out there, which one is the latest?

RE: Pinguino with ART2003
Sorry, I have no experience with the 4550. According to the datasheet they should be the same.

Follow this guide: http://products.foxdelta.com/art2003.htm

I've etched a board like he has done. It works perfectly. If you click identify board (or something like that) in winpic800 it must tell you the name off the board.

It's not much but I hope you succeed Wink
