The LCD controller can then DMA it out of there using EDMA. Edit: For reference, GSPI octal SPI is perfectly supported, as Deouss shows below. What I mean is that there's not direct connection between the octal SPI PSRAM and any external LCD logic. You're still perfectly able to use ...
The input impedance at A0 is 330Kohm (probably true for all such boards), so if you want to increase the max voltage further, you can add a resistor in series with A0 R = Vmax * 100-330 K. As I said previously if you want to decrease the Vmax with a little soldering* skill you...
For those with the same issue, these repositories have a solution: Solution Summary: use a bitbang implementation for the touch sensor instead of a hardware spi bus https://github.com/AllanOricil/esp32-lvgl-lcd-touch-sd-card obs: main branch uses lvgl 7 obs: lvgl-8 branch used lvgl 8 ...

I2S interfaces with DMA UART 10-bit ADC Best Pins to Use – ESP8266 One important thing to notice about ESP8266 is that the GPIO number doesn’t match the label on the board silkscreen. For example, D0 corresponds to GPIO16 and D1 corresponds to GPIO5. ...
