Information Command	Decription
MM.INFO(BATTERY)	PICOCALC ONLY Returns the current battery level percentage (0-100).
MM.INFO(CHARGING)	PICOCALC ONLY Returns 1 if battery is charging on external power, 0 if battery is not charging.

Option Command	Decription

INSTALL PICO SDK

sudo apt update && sudo apt install -y cmake gcc-arm-none-eabi libnewlib-arm-none-eabi build-essential git

mkdir -p ~/pico && cd ~/pico
git clone https://github.com/raspberrypi/pico-sdk.git
cd pico-sdk
git checkout tags/2.1.1 -b sdk2.1.1
git submodule update --init

echo 'export PICO_SDK_PATH=~/pico/pico-sdk' >> ~/.bashrc
source ~/.bashrc

SETUP PICOCALC FIRMWARE

mkdir -p ~/picocalc && cd ~/picocalc
git clone https://github.com/madcock/PicoMiteAllVersions.git

EDIT ~/picocalc/PicoMiteAllVersions/CMakeLists.txt TO CHOOSE TARGET

set(PICOCALC true)

# Compile for PICO 1 Board
#set(COMPILE PICO)

# Compile for PICO 2 Board
#set(COMPILE PICORP2350)
set(COMPILE WEBRP2350)

BUILD PICOCALC FIRMWARE

cd ~/picocalc/PicoMiteAllVersions
mkdir build
cd build
cmake ..
make

(original readme follows...)

PicoMiteRP2350

This contains files to build MMbasic V6.00.02 to run on both RP2040 and RP2350
Compile with GCC 13.3.1 arm-none-eabi

Build with sdk V2.1.1 but replace gpio.c, gpio.h, float_sci_m33_vfp.S, and flash.c with the ones included here

Change CMakeLists.txt line 4 to determine which variant to build

RP2040
set(COMPILE PICO)
set(COMPILE VGA)
set(COMPILE PICOUSB)
set(COMPILE VGAUSB)
set(COMPILE WEB)

RP2350
set(COMPILE PICORP2350)
set(COMPILE VGARP2350)
set(COMPILE PICOUSBRP2350)
set(COMPILE VGAUSBRP2350)
set(COMPILE HDMI)
set(COMPILE HDMIUSB)
set(COMPILE WEBRP2350)

Any of the RP2350 variants or the RP2040 variants can be built by simply changing the set(COMPILE aaaa)
However, to swap between a rp2040 build and a rp2350 build (or visa versa) needs a different build directory. The process for doing this is as follows:
Close VSCode
Rename the current build directory - e.g. build -> buildrp2040
Rename the inactive build directory - e.g. buildrp2350 -> build
edit CMakeLists.txt to choose a setting for the other chip and save it - e.g. set(COMPILE PICO) -> set(COMPILE PICORP2350)
Restart VSCode
