Features

• MCU: RP2040, 133MHz Dual core.
• 5 keys for user-defined functions.
• 17 keys for number pad.
• TFT display for calculator if no HID attached.
• 2 macro control keys, RECORD and PLAY.

Plans for future features

• A flash memory to store user configurations? (currently, they're stored at SRAM of MCU only, so, volatile)
• I2C or SPI extension port?
• A little game that runs on the TFT display?
• Anything else...

Firmware

Current planed features are implemented. Now, calculator mode will be implemented soon.

Don't use 0.15.0 distribution that included on pico-sdk. Update its branch to above version, then it works perfectly.
