# Testing platforio and esp
|
|
|
|
|
|
|
|
|
|
## Rationale
|
|
|
|
|
|
|
|
|
|
I notices that i have to start smaller, make test.
|
|
|
|
|
|
|
|
|
|
Also, while python was great, the library handling was (really) _bad_ .
|
|
|
|
|
|
|
|
|
|
Since PlatformIO finally allows to add code to git and share it i chose that
|
|
|
|
|
over plain Arduino.
|
|
|
|
|
|
|
|
|
|
And the Basic is such an unbeatable package of esp, power supply, relay and case.
|
|
|
|
|
Even with ce mark. So here we go...
|
|
|
|
|
|
|
|
|
|
## File structure
|
|
|
|
|
|
|
|
|
|
This whole directory is a PlatformIO project. Testing . . .
|
|
|
|
|
|
|
|
|
|
I am not sure what parts are machine specific and thus have to be left out.
|
|
|
|
|
|
|
|
|
|
## Esp
|
|
|
|
|
|
|
|
|
|
Or to be precise a SonOff Basic v1.3 is the target.
|
|
|
|
|
|
|
|
|
|
I have this wired with an UNO as a programmer according to https://www.youtube.com/watch?v=qOztsbEfg1g
|
|
|
|
|
This just bridges the uno and uses its usb chip to pass the programm on.
|
|
|
|
|
The net says a usb to TTL programmer is the "normal" way, just have not bought one.
|
|
|
|
|
|
|
|
|
|
## Code
|
|
|
|
|
|
|
|
|
|
The actual code i am trying to write will use the Basic to switch a Fan.
|
|
|
|
|
|
|
|
|
|
I will add 2 DHT22 in a case like this https://www.thingiverse.com/thing:4852992
|
|
|
|
|
|
|
|
|
|
The sketch will simply compare temeratures and switch the relay on/off

### Development
|
|
|
|
|
|
|
|
|
|
Turns out the Sonoff Basic has very very little free pins. Maybe just one.
|
|
|
|
|
|
|
|
|
|
So to use it we will have to use rx/tx for the sensors, which does make Development
|
|
|
|
|
difficult (no Serial). So i will develop on a D1 Mini that is also a 8266.
|
|
|
|
|
|
|
|
|
|
OTA is already working and so once debugging is done it "should" just be upload.
|
|
|
|
|
But i'll make a backdoor to dump serial links to the web interface that i am planning anyway.
