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

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
