MachiKania Phyllosoma
MachiKania Phyllosoma is a BASIC compiler for ARMv6-M, especially for Raspberry Pi Pico.
cmake and make. The pico-sdk (ver 1.4 is confirmed for building) with tinyusb submodule (ver 0.14.0 is confirmed for building) is required.
Copy "phyllosoma.uf2" to the RPI-RP2 drive of Raspberry Pi Pico. Immediately connect to COMx port (com number depends on environment) by serial console at 115200 baud rate, if needed. Alternatively, copy "phyllosoma_kb.uf2" to the RPI-RP2 drive of Raspberry Pi Pico for using USB keyboard directly connected to Raspberry Pi Pico.
Most of codes (written in C) are provided with LGPL 2.1 license, but some codes are provided with the other licenses. See the comment of each file.
Connect a Raspberry Pi Pico to an ILI9341-based LCD (SPI connection) and an MultiMediaCard (SPI connection) as follows.
Note that USB keyboard is connected to micro-USB B port of Raspberry Pi Pico board when required.

GP29 ADC3The phyllosoma_kb.uf2 firmware supports using USB keyboard. Connect the USB keyboard to micro B socket of Raspberry Pi pico through an USB-OTG cable, and supply 5V power to VBUS pin (#40).
Alternatevely, as before, the phyllosoma.uf2 firmware supports the USB serial connection between MachiKania and PC.
