waveshare pico eval board setup file #1928

Closed klspstck closed 2 years ago

klspstck commented 2 years ago

Good morning,

I want to use the above mentioned board to play around with. Waveshare provides a Micropython graphics example which works. Their "C" example doesn't. I don't see any activity on the TFT_CS pin)

The board uses that serial-parallel conversion with 4040,4094 and 7404

Because I used your library successfully with an ESP32 I wanted to try your library with pico and the display.

I am familiar with your concept of "user_setup.h" files.

I am able to compile your colour test and upload it, but the display stays dark.

Obviously something is missing.

I used the following settings in my file:

define USER_SETUP_ID 0xFFFFFFFF

define RP2040_PIO_SPI

define ILI9488_DRIVER

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_FONT8N // Font 8. Alternative to Font 8 above, slightly narrower, so 3 digits fit a 160 pixel TFT

define LOAD_GFXFF // FreeFonts. Include access to the 48 Adafruit_GFX free fonts FF1 to FF48 and custom fonts

// Comment out the #define below to stop the SPIFFS filing system and smooth font code being loaded // this will save ~20kbytes of FLASH

define SMOOTH_FONT

define TFT_SPI_PORT 1

define TFT_MISO 12

define TFT_MOSI 11

define TFT_SCLK 10

define TFT_CS 9 // Chip select control pin

define TFT_DC 8 // Data Command control pin

define TFT_RST 15 // Reset pin (could connect to Arduino RESET pin)

// the pico_eval_board has backlight control

define TFT_BL 13 // LED back-light control pin

define TFT_BACKLIGHT_ON HIGH // Level to turn ON back-light (HIGH or LOW)

define SPI_FREQUENCY 20000000

define SPI_READ_FREQUENCY 20000000

define SPI_TOUCH_FREQUENCY 2500000

I do see activity on the important pins TFT_CS, TFT_DC, TFT_SCLK and TFT_MOSI. Commands are 8 bit and data is 16 bit according to my scope.

Any ideas what I may have forgotten?

Do you need more information or logs?

Kind regards Klaus P. Stock

Comment out or delete the line:

define RP2040_PIO_SPI

Bodmer commented 2 years ago

For that interface type you also need to add this line to the setup:

define RPI_DISPLAY_TYPE

klspstck commented 2 years ago

Good morning Mr. Bodmer,

I applied both modifications and now I do see the colour demo. :-))

Thank you for your immediate help. This saved my weekend.

I am attaching my config file, which you may use as an additional config file in your library.

ON to the next problem now ;-))

Kind regards Klaus P. Stock

Good morning,

one more thing: I also had to turn on inverse colours.

But now everything works as expected.

Kind regards Klaus P. Stock
