Re: Help Needed
Depends on the serial ports, if you get a usb to serial converter you can add upto 255 ports and more, but if you stick with the standard serial ports you would need to use a custom hardware board to provide additional ports past the 1-2 provided by the out of the box computer

This is a lot easier if you use the free visual studio express edition then you can use this code example

Sure its not C but since you do not...

Hi All,
I am attempting to learn VHDL using a digilent board and example and have a very basic question.
The code is ...

I am not sure what your question is the attached code appears to be pretty complete did you compile and run it? What problems are you running into?
Re: full obd prpject..
looks like the OBD portion only implements ISO9141 protocol and not any other so most likely will not work unless the vehicle supports ISO9141
A pic has a pretty simploe architecture so you might be better off just designing your own board, I would lay out all the peripherals and then start out by populating only the xtal circuitry and maybe a led that you can blink using an ICSP.
Most of the microchip datasheet show the minimal...
Do you know who sells these? Prolific's website does not have any info and mentions speaking with their FAE, I would like to explore this option since the FT232RL solution is a bit more expensive.
This looks OK, the bootloader will look for the first 4 bytes GOTO START and place them in the right location, this code looks like it will work correctly do yo have a way to test it without the bootloader? The start vector is correct, and will be relocated appropriately.
Hi Post your actual program looking at the bootloader source looks like your actal program needs to start with a GOTO PROGSTART instruction.
The bootloader will look for this and patch your program accordingly.
