How to compile uLisp

uLisp for PicoCalc uses Arduino IDE for development

All the operations in this document are performed in a Linux environment. A basic understanding of Linux, as well as familiarity with Git and Arduino development, is required.

Install arduino-pico

Open up the Arduino IDE and go to File->Preferences.

In the dialog that pops up, enter the following URL in the "Additional Boards Manager URLs" field:

https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json

Hit OK to close the dialog.

Go to Tools->Boards->Board Manager in the IDE

Type "pico" in the search box and select "Add":

Patch code

git clone https://github.com/technoblogy/ulisp-arm.git

cd uLisp-arm

git reset --hard 97e61151dfb236311089abd3e89029e367613f70  #Switch to the required version

git clone  https://github.com/clockworkpi/PicoCalc.git #get patch code

git apply  PicoCalc/Code/uLisp/uLisp.patch

Install TFT_eSPI 2.5.34 in arduino ide and patch it

cp patches/Setup60_RP2040_ILI9488.h ~/Arduino/libraries/TFT_eSPI/User_Setups/Setup60_RP2040_ILI9488.h

Add a new include

#include <User_Setups/Setup60_RP2040_ILI9488.h> 

and comment out

#include <User_Setup.h>

in ~/Arduino/libraries/TFT_eSPI/User_Setup_Select.h

Install arduino_picocalc_kbd for interacting with picocalc's keyboard via i2c.

cd ~/Arduino/libraries
git clone https://github.com/cuu/arduino_picocalc_kbd.git

Compile and upload

In arduino ide ,config board and other arguments

Put pico in BOOTSEL mode by pressing BOOTSEL key and power on it

Hit the upload button in arduino ide

Here is the screenshot for reference:

It should be noted that uLisp's default serial port speed is 9600
