Ch55xduino, Arduino development package for ch55x

[ds_user]

Ch55xduino is an Arduino-like programming API for the CH55X, a family of low-cost MCS51 USB MCU. The project tries to remove the difficulty of setting up a compiling environment. Users can simply write code in Arduino IDE and hit one button to flash the chip to get code running. No configuration or guesswork needed.

CH551/2/4 may be the lowest part count system that works with Arduino. The minimal system only requires one chip, 2 decoupling capacitors, and one optional pull-up resistor. These features made it ideal for DIY projects.

At this moment the project is still working-in-progress. Support most Arduino functions (Except pulse, shift, tone). Refer to examples in this repo for more info.

Hi

Any plans to include the 554 - 559 range of C51 Processors in the Arduino ide.

I am developing a USB mass storage interface to read a U-disk - Pendrive and looking to use Arduino.

regards

It is planned to support CH554 but not finished yet. However, you can choose CH552 and your own USB stack to make it work. Also the example above is the basic code to jump into boot loader. You can use serial to upload sketch when your USB port is occupied.

Are there any english datasheets available for the CH55x series?
