So this is a TV tuner (for UHF/VHF, which one might note are no longer broadcast in much of the developed world), with I2C control to choose the channel?
You're using an 8-bit address, while the Espruino uses the 7-bit address and handles the last bit for you. You need to shift that address one bit to the right, ie, 0x61.
Also, there are 3 other addresses it could use - try em all if that one doesn't work.
I'm trying to do this
is arduino code
I have as follows
The function "tuner" does the major work but it does not seem to work since the tuner does not alter his tencion.
This one is a project that I would like to complete. If someone can check my code he would be grateful for it very much
