Hello,

I've got a Pharos GPS-500 USB dongle on hand and I was wondering if it would be possible to hook this up to a PIC of some kind. When I plug it into my PC it is detected as a serial port by windows and the data just streams over as ASCII test.

Anyone have a direction they can point me in? I've been looking at Microchip's website, but most of the stuff is on peripheral side devices. On the high end line I see some USB-Host stuff but it seems to be pointed at USB Flash drives. Overall, its all still clear as mud to me. A USB-Host DIY-PIC primer would be really cool...

Thanks!

Take a look at the PIC18F2550/4550 series. They have everything required
for USB except the connector. Microchip has some sample code for serial.
The data sheet is kind of confusing, tho. That USB interface is incredibly
smart, and as a result, kinda hard to understand. But if you can rip off
some Microchip code you might just make it work,

A somewhat clumsier approach is to use a the 18F as a USB to serial
converter, essentially what Microship does on their Explorer 16, 28 pin
starter board, and probably others. That way you don't have to mess with
the USB code, just burn it into the 18F.

Okay, I've figured out a way around it... The Pharos iGPS-500 GPS receiver is a TTL serial device and if you don't mind soldering wires to the edge connector its also easy to get the signals out of the device. Here is a web-page describing it. http://ubermodder.com/budget-usb-enabled-gps/

Good afternoon

I bought a PICKit 3 which came with a PIC 18F45k20 on an experimental printed circuit board, having some LEDs, resistors, a potentiometer, a jumper, and some other things.

When I connected the board to the PICKit 3 programmer, I noticed that the board was powered by the programmer, and the LEDs began to blink. The board had a program inside.

I would like to know please, where may I find the manual of the experimental printed circuit board.

Greetings
Dimitri

If its like the PicKit 2 it will be in "C:\Pk3 Lessons" ...

Good evening, Dave.

Thank you for your kind answer. I went there, but... the only thing I found, was a schematics.

It is even worse. A careful inspection of the schematics is that some of the schematics components are there (like the LEDs and the resistors that limit their current), but some of them are not (like some capacitors and a clock quartz oscillator).

A further search on Internet revealed that there is no manual on the board. I am very disappointed. I paid a lot of money for the board and the PICKit 3, I think, a manual would be the least of things...

Greetings and thanks.
Dimitri
