LilyGo MicroPython

Index

Install Prerequisites

To compile with lilygo-micropython you need to get the following packages. The command to run depends on which distribution of Linux you are using:

  • Ubuntu and Debian:
sudo apt-get install git make python3 python3-pip cmake quilt libusb-1.0-0-dev libusb-dev libudev-dev

Supported Boards

  • LILYGO T-SIM7000G
  • LILYGO T5-4.7
  • LILYGO T-T-CALL SIM800
  • LILYGO T-PicoC3
  • LILYGO T5-4.7 Plus (esp32s3)
  • LILYGO T-Echo
  • LILYGO T-Display
  • LILYGO T-DisplayS3
  • LILYGO T-RGB
  • LILYGO T7-S3
  • LILYGO T-DisplayS3-AMOLED

Build

T-SIM7000G

$ cp config_T-SIM7000G config
$ make

T5-4.7

$ cp config_T5-4.7 config
$ make

T-CALL SIM800

$ cp config_T-CALL config
$ make

T-PicoC3

$ cp config_T-PicoC3 config
$ sudo apt install gcc-arm-none-eabi libnewlib-arm-none-eabi build-essential
$ make

T5-4.7 Plus

$ cp config_T5-4.7-Plus config
$ make

T-Echo

$ cp config_T-Echo config

Use circuitpython by default

To use micropython, you need to modify the config file:

--- config_T-Echo       2022-07-13 17:11:04.374660308 +0800
+++ config      2022-07-13 17:11:00.694565940 +0800

Issue

1. Compilation error caused by ninja

Compilation gives the following error:

```
ninja: build stopped: subcommand failed.
ninja failed with exit code 1
make[1]: *** [Makefile:42: all] Error 2
make[1]: Leaving directory '/home/scruss/c/lilygo-micropython/build_dir/esp32s3/micropython/ports/esp32'
make: *** [Makefile:36: all] Error 2
```

Please uninstall ninja and try to compile again

```shell
sudo apt remove ninja-build
rm build_dir -rf
```

Future plans

  • Support menuconfig
  • More boards
  • Complete development documentation
