Touch

[ionciubotaru]

Please write some details about the communication between touch and ESP.
Is it I2C or SPI ?
Any information and some examples for arduino IDE lovers will be welcome :)

Some source code (or at least any info you have about the interaction between the touch IC and the ESP8285 would be very helpful indeed.)

Thanks in advance!

Thank you for source code.

Please confirm if is correct:
relay pin - GPIO 12 - output
led pin - GPIO 13 - output
touch pin - GPIO 0 - input pullup

Did I understand correctly ?
GPIO 0 is used for communication between touch IC and ESP, active low ?
Is it possible to put ESP in programming mode using the touch ?

This is fantastic - I now have my own Sonoff-touch code working. Thank you!

GPIO0 is indeed active low but you can't get it into programming mode via the touch (at least, I can't). I think the touch IC is too slow to boot and pull GPIO0 low before the ESP8265 has already booted.

My code is on:

(Also OTA update is possible :D)
