Seeed Xiao Rp2040 and GC9A01 stop working after updates

[djairjr]

Hi Bodmer.
A few months ago, I´ve managed to run Animated Eyes example using the Seeed Xiao Rp2040 and two GC9A01 round displays.
https://www.pcbway.com/project/shareproject/Finally_Animated_Eyes_using_Seed_Xiao_RP2040_d7af7894.html

Now the same code does not work. I´ve made all upgrades in Erle core and the default Arduino for Rp2040 core. And use same UserSetup, but there is no image at all.

The Read_User_Setup example does not return the correct SPI Pinouts (used by Seeed Xiao Rp2040). Instead, return this:

[code]
TFT_eSPI ver = 2.4.72
Processor = RP2040
Transactions = Yes
Interface = SPI
Display driver = 9A01
Display width = 240
Display height = 240

MOSI = GPIO 3
SCK = GPIO 2
TFT_CS = GPIO 31
TFT_DC = GPIO 6
TFT_RST = GPIO 7

TFT_BL = GPIO -1
TFT_BACKLIGHT_ON = HIGH

Font GLCD loaded
Font 2 loaded
Font 4 loaded
Font 6 loaded
Font 7 loaded
Font 8 loaded
Smooth font enabled

Display SPI frequency = 27.00
[/code]

In my custom user setup, the pin definitions are as follows:

[code]
#define RP2040_PIO_SPI // Erle Core
#define GC9A01_DRIVER // Round TFT SPI Display

#define TFT_WIDTH 240 // ST7789 240 x 240 and 240 x 320
#define TFT_HEIGHT 240 // GC9A01 240 x 240

#define TFT_SCLK SCK // PIN D8 VERDE
#define TFT_MOSI MOSI // TX PIN D10 AZUL
#define TFT_CS SS // Chip select control PIN D7
// Second one is D6 Pin
#define TFT_DC D4 // Data Command control PIN D4
#define TFT_RST D5 // Reset pin

#define TFT_BL -1 // LED back-light control pin
#define TFT_BACKLIGHT_ON HIGH // Level to turn ON back-light (HIGH or LOW)

#define LOAD_GLCD // Font 1. Original Adafruit 8 pixel font needs ~1820 bytes in FLASH
#define LOAD_FONT2 // Font 2. Small 16 pixel high font, needs ~3534 bytes in FLASH, 96 characters
#define LOAD_FONT4 // Font 4. Medium 26 pixel high font, needs ~5848 bytes in FLASH, 96 characters
#define LOAD_FONT6 // Font 6. Large 48 pixel font, needs ~2666 bytes in FLASH, only characters 1234567890:-.apm
#define LOAD_FONT7 // Font 7. 7 segment 48 pixel font, needs ~2438 bytes in FLASH, only characters 1234567890:.
#define LOAD_FONT8 // Font 8. Large 75 pixel font needs ~3256 bytes in FLASH, only characters 1234567890:-.
#define LOAD_GFXFF // FreeFonts. Include access to the 48 Adafruit_GFX free fonts FF1 to FF48 and custom fonts

#define SMOOTH_FONT
// #define PIXEL_DOUBLE

//#define SPI_FREQUENCY 20000000
#define SPI_FREQUENCY 27000000
//#define SPI_FREQUENCY 40000000
//#define SPI_FREQUENCY 62500000
//#define SPI_FREQUENCY 80000000

// Optional reduced SPI frequency for reading TFT
#define SPI_READ_FREQUENCY 5000000
[/code]

Check the User_Setup_Select.h file is calling up the correct setup file. When this is correct then the Read_User_Setup sketch will report the defined pins set.

My User_Setup_Select.h file is correct and pointing to the correct setup file.

Try commenting out this line thus:

// #define RP2040_PIO_SPI

The built in SPI port will then be used.

[djairjr]

Commenting this line does not make any changes.

Bodmer, my first attempts to recover the operation of the system were precisely the ones you have recommended. I am repeating only for confirmation, intending to help solve the problem.
In addition to the ones you recommend, I've already disabled DMA in the AnimatedEyes script itself.
Commenting line
#define USE_DMA
I also tried several speed settings of the SPI Bus.
My next check will be regarding the boot sequence of the display itself.

Assuming you are trying to use the GPIO pins in #2000 then I tested my display with the following setup file and it is working fine:

#define RP2040_PIO_SPI

#define GC9A01_DRIVER

#define TFT_MOSI  10
#define TFT_MISO  9 // Not connected to display
#define TFT_SCLK  8
#define TFT_CS   7  // Chip select control pin
#define TFT_DC   4  // Data Command control pin
#define TFT_RST  5  // Reset pin (could connect to Arduino RESET pin)

#define LOAD_GLCD   // Font 1. Original Adafruit 8 pixel font needs ~1820 bytes in FLASH
#define LOAD_FONT2  // Font 2. Small 16 pixel high font, needs ~3534 bytes in FLASH, 96 characters
#define LOAD_FONT4  // Font 4. Medium 26 pixel high font, needs ~5848 bytes in FLASH, 96 characters
#define LOAD_FONT6  // Font 6. Large 48 pixel font, needs ~2666 bytes in FLASH, only characters 1234567890:-.apm
#define LOAD_FONT7  // Font 7. 7 segment 48 pixel font, needs ~2438 bytes in FLASH, only characters 1234567890:-.
#define LOAD_FONT8  // Font 8. Large 75 pixel font needs ~3256 bytes in FLASH, only characters 1234567890:-.
#define LOAD_GFXFF  // FreeFonts. Include access to the 48 Adafruit_GFX free fonts FF1 to FF48 and custom fonts

#define SMOOTH_FONT

#define SPI_FREQUENCY  33000000
#define SPI_READ_FREQUENCY  20000000
#define SPI_TOUCH_FREQUENCY  2500000

I am using Phil's latest board package v 2.5.2
Not sure what to suggest.
