Hi,
Was just trying to do some reverse engineering on this hwd with same intention to use it with ESPhome this week end…
For the display connection I came-up with the following pins connection:
|1| GND
|2| GP0 → D/C
|3| GND → CS ? tied to GND
|4| GP14 → SCK
|5| GP13 → MOSI
|6| GP2 - > reset ?
|7| VCC
|8| GND
|9| GP5 → Back-light Anode through P MOSFet
|10| GND → Back-light Cathode
I’ll have a try tomorrow in esphome with something like:
esphome:
name: small-tv
friendly_name: small-tv
