tmr.alarm() in callback = reboot loop?
Posted: Sun Mar 29, 2015 3:51 amHi everyone,
I'm new to nodemcu, but I got to say developing for a µC with an interpreted language is a breeze. I'm using "NodeMCU 0.9.5 build 20150213 powered by Lua 5.1.4" (0x00000.bin, 0x10000.bin from https://github.com/nodemcu/nodemcu-flasher/tree/master/Resources/Binaries).
I have downloaded two file onto the esp8266 filesystem: init.lua and webap_toggle_pin.lua. The last one is basically the net.createServer(net.TCP) from the nodemcu-firmware repo. But instead of gpio.write(...) I call illuminate(...), which is implemented in time.lua.
init.lua:
time.lua:
As long as tmr.alarm(...) is commented out, I can download time.lua and everything is fine. But as soon as I download the uncommented version and reset the node, it is in a reset loop. What's going on?
Am I not supposed to call tmr.alarm() in a callback function? Am I missing something?
