All the changes and additions to Lua in my GitHub repository are mine.
Seed studio’s Lua implementation is very limited (more or less just enough to prove that it can work).
I’m working hard on making the Rephone Lua more complete. Many improvements and additions are made from the last GitHub commit, they will be committed soon.
os and debug modules and coroutines are supported, many improvements to gpio (support for all rephone gpio’s), tcp, https (full support for post method, including file transfer), sensor module (DS1820, DHT11/22,…), memory and heap management improvements, watchdog, shell on USB or UART, scheduled shut down/wake up, NTP support, struct module added, json module … and many more.
When ready, I’ll post the information and the complete documentation for added functions/functionality on this forum.
