Upload with MiniPro?

Development Platforms
1

I have a handful of AT89S52 chips here, and a TL866 II-Plus programmer. Is there a way to create a custom “board” that is just the microcontroller itself and set MiniPro as the upload protocol?

I don’t see that chip being supported in PlatformIO Registry directly. If it’s a generic Intel 8051 variant you might have luck basing a new board off https://github.com/platformio/platform-intel_mcs51/blob/develop/boards/stc89c52rc.json as base, using sdcc as the compiler (docs). You would however also need to teach the platform the new upload program (idk what you use for uploading) via a custom upload protocol, as there’s only stcgal support (docs) .

So the good news is, I am about 40% of the way there. Not knowing what I am doing is a slight hinderance, but hacking up some MiniPro support will probably be quite advantageous. I will attempt tp submit what I create when I am done.

Hello, I’ve created a simple github action that builds the minipro tool for windows here. Download the zip file for your platform and uncompress it on the %HOMEPATH%\.platformio\packages\tool-minipro. (create the directory if it doesn’t exist)
On Linux, just checkout the sources from here, build it (just make), and copy minipro, infoic.xml and logicic.xml to ~/.platformio/packages/tool-minipro. (create the directory if it doesn’t exist)

I then added the following on my platformio.ini:

upload_protocol = custom
upload_flags =
    -p
    AT29C512
    --infoic
    ${platformio.packages_dir}/tool-minipro/infoic.xml
    --logicic
    ${platformio.packages_dir}/tool-minipro/logicic.xml
upload_command = ${platformio.packages_dir}/tool-minipro/minipro.exe $UPLOAD_FLAGS -w $SOURCE

Note that I’m using a AT29C512 flash for my particular project, edit it appropriately for your project! If you’re on Linux, don’t use minipro.exe but rather just minipro on the upload_command.

I know this post is old, but it might be useful for someone :slight_smile:
