Hi all, I have an old TFT Touch Screen shield from SeeedStudio, that works well on Uno or Mega. I use the SeedStudio library TFTv2, the display drive is IL9341.
Recently I bought an UNO like card with ESP-32. Stupid me thought, that it was pin-compatible with UNO, why else should anyone build a card like UNO?
So here I am with a card with almost every pin different from UNO. But I like the ESP-32 for it's speed. I have built a few projects with it even using it's dual core.
The card doesn't have the 6pin SPI connector, but luckily there are jumpers on the TFT card, connecting the SPI (MOSI, MISO, SCK) to pins 11, 12, 13 on UNO.
Is there anyone, who solved this problem or has enough knowledge to help me do it? The reason for this could be, that SeeedStudio sells this card for $10, while Adafruit has 2.8" TFT for $35.
Questions are: 1. do I have to involve level shifters up from 3.3V to 5V ? (kind of awkward, since there are level shifters down on the TFT card) 2. which library do I use? Or at least to start with and adapt to my HW. (there are a few alternatives - SeeedStudios TFTv2, Adafruit_ILI9341_AS, Bodmer's TFT_eSPI,...)
Any hint to solve this will be appreciated. Thank you.
By the way, is there anyone who knows how do I contact Bodmer?
