EEVblog #411 - MiniPro TL866 Universal Programmer Review

<< < (413/413)

Spongey:
I've written another experimental little utility program for the T48. This one is called "mprom" and an experimental version called "mprom-bb". It is here.

What it does is allow parallel ROMs to be read fairly painlessly using a T48. It has some similarities to the prom.c code in minipro (which isn't currently compatible with T48) but it's more flexible. Adding a new ROM is just a case of adding pin definitions to an XML file (see roms.xml in the utility).

The "mprom-bb" version can theoretically be extended to use the ISP pins for chips needing more than 40 pins in an adapter. That needs some additional configuration with adapter pin maps which I currently don't have. Anyone wanting to help out with that please send me a message.

Although this has been tested with a T48 it should also work with a TL866II+. It will not work with TL866A/CS.

I don't think it will currently work with a T56 either but feel free to try it out.

Any reports welcomed especially if you don't mind experimenting a bit to get some things working.

I have had the exact same problem with my TSOP48/SOP44 adapter attached to TL866CS since day one (never changed ATTINY, it recognizes as 'V3').. Did you ever figure it out?

Spongey:
Yet another minipro experimental utility I've written. This might be of wider interest...

It's a python GUI that allows you to explore logic (and other) chips. You can set pins to appropriate logic levels and read back the results.

I'm working on getting it into a usable state: demo video here.

It has been developed using a T48 and should work fine on a TL866II+. Untested T56 support is also present. I don't think it's practical to get it going on the older TL866A/CS: I don't have acess to one and it would be a lot of work and it is missing some features of later models.

Currently at an early stage of development and it's a bit of a learning curve for me with python: which I hadn't used much before.

Update: very preliminary version is here.

Comments welcome (private message, gitlab or on this thread).
