- Wed May 27, 2015 8:24 pm #18681 Good day,

I need the ESP (Mod 01) for a very small application.
The first GPIO gets one pulse per second, while the second GPIO gezs a signal, once a button is being pushed.
Additionally the 'time' between the pps - signal has to be interpolated / calculated. On button-press, the current timestamp / time has to be send out via WIFI.

Shall I do this via a custom ESP-firmware, that LUA-firmware or use an aditional CPU? Any suggestions?

My 2 cents... Cheers,
John

Ack.
And if your missing piece in lua makes a good c function, just implement in c and call it from lua.
Either as a new module or just hijackking some existing module like "node" and adding a function to start with.

In this discurs I was involved in "wifi" got a "dump" function for debugging a lua/c issue. Code is not included
but straight forward.
