The work you have done with reprogramming the xilinx device via the pic is fantastic. Have you tried to reprogram any Altera based devices? I have a pet project where I am trying to reprogram a max II cpld using a pic24f. If you could point me in the direction of any kind of info it would be really appreciated.
Thanks!

Being able to do MPS430 programming with the JTAG would be very nice.

hello,I live in Brazil
I have practiced with these devices
I need to reset the DS2431, it goes to a printer, to check the print cartridge
it is giving 0% of fluid inside the cartridge,
how can I do this?
thanks

Can anyone tell me if I could use a bus pirate to sniff out the data on a (on board modem) chipset? Say I wanted to sniff all of the data being sent to an old dial-up modem?

@neil h.

What firmware did you use? v0g is the newest.

Just built one and am testing it. I am seeing something odd.

Has anyone tried the Aux pin support @/a/A commands? It seems as if the chip never pulls the output high in the A command (it goes from 0.0 to 0.25 V) it’s as if the internal pullups on that port pin are not being enabled.

Just wondering if anyone else has seen this? I have checked for pin shorts etc… The serial interface comes up perfectly etc…

Great project, am looking forward to putting it to use. Thanks

–Neil.

Everything I know is from the Xilinx documentation linked in this post.

Hi ,

I need to do convert SVF file into XSVF file with out Impact or any software, need to make it. Can you please refer me some document which tells about the SVF and XSVF instruction so that I can write one converter for that.

Thanks,
Appu

The Sanguino (64kb flash, 4k RAM 20MHz) would be a better fit for this project. I don’t see anything in the circuit that couldn’t be done with the standard Sanguino board. But then again, I’m not an expert… Some isolation circuitry would be nice, but as mentioned, the bi-directional interface will make that more difficult. Where can we find the source code?

About your “//disable some default nonsense” comment inside main.c… All analog capable ports are configured as analog input at startup to consume less power: if left as digital input and disconnected, the input floats and can change its state randomly, and every time the state changes the input transistor consumes current. microchip says that for low power consumption the progammer should have every unused pin configured:
- as an analog input
- as an input, but tied to vcc or gnd
- as an output, unconnected

Since mchp doesn’t know your hardware beforehand, it places the chip in the safest state.
Remember, nothing is nonsense, everything is carefully studied!

@njansen: Yes please create a project on SF. I am in for the arduino port. I have a couple of arduino nanos handy: 16Mhz avr168 (1k sram, 16k flash). Some features will have to go due to lack of space. We can turn them into compile time options so people can enable what they need (or use a higher spec’ed AVR). Let us know when the SF project is up!

Also a nice PC gui interface would be very nice. Something portable, I recomend writing it in python.

I second the requests for PIC and AVR ICSP programming and ODB-II

Adding these features should be fairly easy, source code is provided too:
http://mondo-technology.com/super.html

Also, with the increasing number of features, a GUI should be nice.. maybe java or python for portability, I don’t know, I’m a windows guy (I can help develop it in c# .net if needed).
An USB version with a 24fj256gb108 will be nice (I’m working with this pic at the moment and it is very cool!).
Most important, a bootloader, so we don’t have to move our ICD2 around to update the firmware. I’m using the very good AN1157 (http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1824&appnote=en533906) for my project.

@ Daryl linux serial ports are usually in /dev/tty/s0 and usually work by default.

Excellent improvement to an already good tool. Good idea on the jtag compatability. Any chance of getting an AVR version together anytime soon?
