I built the this schematic https://raw.github.com/adafruit/TV-B-Go ... ne3sch.png in a protoboard
The only modifications is:
I am using Dispark ATtiny85:
I am using a 8MHZ crystal with 2 capacitors of 18pF
I could do the Upload of the tvbgone.hex and could see (with a cam) the IR leds blinking. But I couldn't turn off any TV.
So I checked the fuses: E:FE, H:DD, L:E1
I modified the fuses using: avrdude -b 19200 -P /dev/ttyACM0 -c avrisp -p t85 -U lfuse:w:0xfd:m -U hfuse:w:0xde:m
The avr did the modifications, and I could read the values of fuses.
But....
When I plugged the Digispark again in the circuit, the leds, didn't blink anymore.
I tried read the fuses values again (I am using Arduino Uno as a Programmer) and now It was not possible:
avrdude: Device signature = 0x000000
avrdude: Yikes! Invalid device signature.
Double check connections and try again, or use -F to override
this check.
What is wrong? Is my board dead?
Pleas help. I would like to use these project to arduino day next 12th
