Sensor Watch Lite Cortex M0+ board

[matheusmoreira]

Description

I would like to request support for the Sensor Watch Lite board. It is a replacement movement for Casio F-91W wristwatches which gives it numerous new features while maintaining low power requirements and the original watch's form factor.

Usage example

It will be used for open source firmware development.

Currently there is a relatively low accuracy simulator implemented in the browser. It has limitations, for exampel it freezes if when an attempt is made to test low power sleep modes. It also requires the firmware to be compiled with emscripten.

Better tools are required for efficient software development. A proper emulator for the board and its microcontroller would allow testing to be much more efficient. It will also run the exact firmware that will execute on real hardware.

Additional information

The board contains a SAM L22 family Cortex M0+ ARMv6-M chip, model ATSAML22J18A. It is open source and developed in KiCAD. Files here: OSO-SWAT-B1. It makes heavy use of the following peripherals:

• Real time clock
• Segmented LCD controller

It also uses the true random number generator and also contains a thermistor temperature sensor.

The SLCD is the same as the one in the Casio F-91W wristwatch.

Do you plan to address this issue and file a PR?

I don't think I have enough electronics knowledge to attempt this myself. I need support.
