ESP-WROVER-KIT and a2dp_sink example

Postby 12pastnoon » Wed Aug 01, 2018 4:29 pm

This is a n00b question. On the ESP-WROVER-KIT is it possible to run the a2dp_sink example (from esp-idf/examples/bluetooth/a2dp_sink)?

I ask because README.md says it uses GPIO25 and GPIO26: On this board GPIO25 is connected to LCD screen and GPIO26 is connected to camera? There is no camera connected right now but will LCD screen be somehow damaged?

It should be fine if you make sure GPIO18 and 22 are low. This way, you keep the LCD deselected and reset, making sure it doesn't try to output anything on GPIO25. If you want to be 100% sure, you can remove the zero-ohm resistor R139 from the board, this disconnects the LCD from GPIO25 entirely.
