Add initial support for CH559 (WIP/RFC) #29

Closed Tonymac32 closed 2 years ago

Tonymac32 commented 4 years ago

The CH559 is a USB microcontroller based on the MCS-51 architecture.

This chip requires a custom upload protocol, I have placed the framework for that in main.py, I am not clear on how to have platformIO grab the necessary python upload tool automagically from here: https://github.com/MarsTechHAN/ch552tool

This tool depends on libusb as well.

Once these details are figured out/solved I can follow with board definitions for the remainder of the CH55x family.

Great PR! This allowed be to create a blinky firmware and flash it on the device using https://github.com/LoveMHz/vnproch55x. (for me, ch55xtool.py has a bug (https://github.com/MarsTechHAN/ch552tool/issues/16) and can't find my device at all, while other tools can find it).

There is also a forked Arduino core based on SDuino (for STM8 devices) available at https://github.com/DeqingSun/ch55xduino, and it works greatly! They also use the vnproch55x flasher per above.

The nice thing with the core is is that once any ch55xduino firmware has been flashed, it exposes a USB serial port that supports the standard reset-to-bootloader mechanism via opening it at 1200 baud. That way one doesn't even have to manually reboot the device by holding a button and switching power on and off.

I'll see if I can get the Arduino core implementation to work and the other uploader based on your work! 👍

The tool has to uploaded into the PIO package repository via pio package publish, then you can reference the package in the platform.json and use a bit of code to tell PIO that you need the pacakge, then use functions like platform.get_package_dir() to get the path to the installed package.

Edit: I've just published the framework-arduinoch55x package and the Win, Linux and Mac versions of tool-vnproch55x and hope they'll be approved soon for usage.

@maxgerhardt nice! The upload tool did not fare so well against some of the newer bootloader revisions on the CH55x devices, I wound up making this PR because I designed a Pi 0 form factor dev board and was hopeful to provide some decent support. After a very extended silence I'd all but forgotten about it. 👀

I'll take a look at the arduino platform, it has been a while since I tried it out.

@Tonymac32 could make a board file name in uppercase? We keep TARGET DEVICES in their original form (typically upper case).

@maxgerhardt what do we need to merge this PR?

Tonymac32 commented 2 years ago

I can take another run at this starting next week, I'm unfortunately in the middle of moving and don't have access to my build system until I set it back up. Thanks for the review!

ivankravets commented 2 years ago

The PR has been merged, the latest version of tool-vnproch55x has been published to the registry. Please re-test with the latest dev-platform:

  1. Upgrade PIO Core to the latest dev version pio upgrade --dev
  2. Use the GIT version of dev-platform in platformio.ini => platform = https://github.com/platformio/platform-intel_mcs51.git
  3. Open the system terminal, change the directory to the project folder, and type pio pkg update.

Does it work now?

maxgerhardt commented 2 years ago

Ah but the upload tool used in this PR is https://github.com/MarsTechHAN/ch552tool, not https://github.com/LoveMHz/vnproch55x (which I was using on the command line), which package you've uploaded.

Also a note on the original issue with ch552tool, this was related to the libusb backend file missing or being a buggy version (I think v1.0.25). Maybe it was fixed with the fresh new release put out a few hours ago, but it was buggy for a really long time. For the Python tool to use libusb devices one needs to have the libusb-1.0.dll in the Python interpreter folder or the program folder. Or use WinUSB drivers with Zadig, I have not tested that.

I have the chip and can test later in the evening.

ivankravets commented 2 years ago

I used these tools (they were recently updated) https://github.com/DeqingSun/ch55xduino/tree/ch55xduino/ch55xduino/tools

Checked on mac OS, and it works. Are they broken?

maxgerhardt commented 2 years ago

Yes ch55xduino uses vnproch55x.exe but this PR calls into ch55xtool.py. I think the binary releases of vnproch55.exe worked fine for me and this is where I had the binaries from.

ivankravets commented 2 years ago

Sorry, I removed your package to avoid duplicates. Let's summarize - should we make any changes regarding this PR?

I found some time for the OSS dev-platforms, I'm not sure that I can back to this repo in the next months. I would be great to merge all PRs and re-test them. Thanks!

maxgerhardt commented 2 years ago

Ah, I see you have already done the second point in https://github.com/platformio/platform-intel_mcs51/commit/6402cc747528692b663cd64535e1493209618b5e, so it should actually be working.

Did this every go through? Sorry to bump an old thread but I'm trying to get PIO working with the CH552! If ch55xduino got in there i should be good to target that slightly different board?

ch55xduino is "not there" This is how I got my board working just recently: https://github.com/danielkucera/ch552-hid/

Wow.. i am amazed at how exactly similar my current project looks to that.. i even have the commented out link_medium.py

Thank you haha! if i learn anything more ill lyk

What version of SDCC are you using?
