[c-logic]

only testet on LilyGo S3 Dongle

[russhughes]

Sorry I've been busy and have not had time to look at this.

[c-logic]

no hurry. I'll test it with a parallel TFT this week. "WT32 SC01 Plus"

[c-logic]

Not yet usable with with i80. the use with i80 runs in a error+reset.

[russhughes]

Found the i80 error. The clock source must be set.

E (66580) lcd_panel.io.i80: lcd_i80_select_periph_clock(504): unsupported clock source: 0
E (66580) lcd_panel.io.i80: esp_lcd_new_i80_bus(154): select periph clock 0 failed

Here is the fix:

Please give a hint how to get the error message.

[c-logic]

the current micropython version does not use the SPIRAM and so the memory is not enough for the frame buffer. (SC01 PLUS)

Error Messages

The error messages are printed to the serial console. This is a problem if you use the native ESP32-S3 USB serial port since the USB is reset whenever there is an error, making it impossible to see the error messages. I use a 3.3-volt USB serial adapter connected to the ESP32-S3's serial TXD0 & RXD0 pins. These pins are available on the WT32-SC01 Plus' Debug Interface connector.

SPIRAM

SPIRAM should be supported but may require using a BOARD_VARIANT like this:

make BOARD=ESP32_GENERIC_S3 BOARD_VARIANT=SPIRAM_SX

I have yet to test this. I will later tonight.

This worked for my WT32-SC01 Plus.

Hope to support micropython 1.21.
