A great new target arrived onto the scene: KittenBot Bridge

1920×1080

Ref: https://pixelfed.social/p/gbraad/91803319722446848

just received this last Friday and so far haven’t had a lot of time to ‘play’ with this, but I do notice that some essentials are still missing. For instance, since there the pin mapping is not known, I haven’t been able to attach a simple TFT yet to the board and try running it with Arcade (target SAM D51). All so far I have been able to do was make the LED blink and use Maker.

It does have a test target at http://maker.kittenbot.cn/ but it does not allow the use of adding extensions. They all fail … Hope more information will arrive, but so far my issues on GitHub and by email have done unanswered.

Note: you might notice there the SD-Wireless inserted to the right. This device allows to communicate with the Micro:bit, but the library https://github.com/KittenBot/pxt-sdwireless did not work for me with this board, and impossible to add to their Maker target. It does work with the Meowbit.

Thanks @mmoskal for suggesting the CF2 patcher . Had seen it before, but now it clicks :wink:

Also got hold of part of the device configuration as used with Maker: https://github.com/gbraad/pxt-maker-kittenbot-bridge

I think a mistake was made here. The Chip Select of the display is not wired to an outside pin.It references PB12, but that pin is referenced as:

PIN_D6 = PB15
PIN_D6 = PB12
PIN_D6 = PA02

which seems odd.

#4

Found the configuration on the Chinese repos: https://gitee.com/Kittenbot/uf2-samdx1/blob/kitten-bridge/boards/kittenbot-bridge/board_config.h

#5

These displays will work with cs just tied to gnd. Maybe this is what they do.

The runtime will take first occurrence of config entry but the patcher will probably take last. Need to fix that mismatch. In any event it looks like a mistake.

#6

From next month KittenBot will be selling the Arcade shield for this device. Production has already started … and here is a small teaser from what was shown at the Maker Faire ShenZhen :wink:
