Getting OV2640 and ST7735S working.
Posted: Mon Jan 13, 2020 5:51 pm
Hi!
I'm currently working on my digital camera project. I got SD card reader actually working but I need a little help with other peripherals.
Using:
ESP32 WiPy 3.0
ESP-IDF
ArduCAM mini 2MP OV2640 with SPI and I2C
Waveshare LCD TFT 1.8" 160x128 ST7735S
Common SD card reader.
I've tried Loboris ESP32_TFT_library but it don't work. Only backlit is working and showing white color, or on other pins it freezes at
I'm not sure but there may be a difference in "B" and "S" revision in controller.
In spirit_master example it says:
I've tried many pin combinations, but error still occurs.
Do you have any working libraries for my controller? Maybe I should write my own (I don't have much time
).
Same with the OV2640. Do you have any working libs? Or maybe SPI lib that can fasten up work?
