pushPixels Results in Blank Screen #38

Closed d42ohpaz closed 3 years ago

d42ohpaz commented 3 years ago

Arduino board: HiLetgo ESP-WROOM-32 ESP32 + Adafruit RA8875 (1590) + Adafruit 7" TFT w/Touchscreen (2354)
Arduino IDE version (found in Arduino -> About Arduino menu): CLion 2021.3
List the steps to reproduce the problem below (if possible attach a sketch or copy the sketch code in too):

https://github.com/9ae8sdf76/dbuddy/blob/master/src/esp32dev.cpp#L58 - rename drawPixels to pushPixels.

I reached out on the forums, but have been overlooked/ignored. I also attempted to get y'alls attention via email, but was ignored there too. So, as a last-ditch effort, I'm reaching out here. I could really use some assistance. Thank you.

hi we cant see the code you're referring to

d42ohpaz commented 3 years ago

@ladyada I have updated the link. My apologies.

ladyada commented 3 years ago

well one sets up addressing and one doesnt. they're not direct replacements.

d42ohpaz commented 3 years ago

Do you have any examples of using pushPixels that I might be able to look over? That may be a naive question, but I am new and trying to learn as I go. :)

ladyada commented 3 years ago

all examples we have are in the library

d42ohpaz commented 3 years ago

What options are there then? When I use drawPixels() the screen draws slowly. I have no point of reference for using pushPixels() - which touts being hardware accelerated. Am I just stuck with a slow display?

ladyada commented 3 years ago

you could try adjusting the code but i dont see how you could get it any faster. the display just isnt that fast since its going thru a mediated board. thers' some shape acceleration on thea ra8875 as this isnt a bug report, closing
