Compile Lua for pico
- Cross compile for pico
- Ensure that all unneeded libs are removed
- I think all we really need is
math
Example Lua code
#include <stdio.h>
#include "pico/stdlib.h"
#include "lua.h"
#include "lauxlib.h"
#include "lualib.h"
void run_lua_script() {
lua_State *L = luaL_newstate(); // Create a new Lua state
luaL_openlibs(L); // Open Lua standard libraries
// Lua script as a string
const char *lua_script = "print('Hello from Lua on Pico!')";
// Execute the Lua script
if (luaL_dostring(L, lua_script)) {
printf("Error: %s\n", lua_tostring(L, -1));
}
lua_close(L); // Close the Lua state
}
int main() {
stdio_init_all();
printf("Starting Lua on Raspberry Pi Pico...\n");
run_lua_script();
while (true) {
// Keep the program running
sleep_ms(1000);
}
return 0;
}
