waveshare pico eval board setup file

[klspstck]

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]

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

[klspstck]

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

Dear Sir,

I can use Pi Pico on the eval board. But no luck with ESP32.
Could you please help to advise how to make it works? Appreciate!

Yours,

PJ.

Good morning, one more thing: I also had to turn on inverse colours. But now everything works as expected. Kind regards Klaus P. Stock

Dear Sirs,

Thanks for your efforts.
I can use Pi Pico on Eval board with the settings above.
However, I still can not make it work with Banana Pi-PicoW-S3: https://wiki.banana-pi.org/BPI-PicoW-S3
It's an ESP32 S3 chip with Pi Pico pinout. It works on SD_MMC, I2S, I2C, and UART but not the LCD on Eval board....
Please advise if there is any direction I can try. Appreciate!

Best regards,

PJ

[Bodmer]

The library assumes that the Arduino library default pins are used, so only the following pin options for the SPI interface will work:
TFT_MOSI 11 or 35
TFT_SCLK 12 or 36
TFT_MISO 13 or 37

You may be able to use different pins when the SPI class instance is created (here in code) but that is not something I will be investigating.

Dear Sir,

Thanks for the reply. Understood your point.
BTW, there is another Waveshare 1.3" IPS TFT LCD HAT for Pi Pico. It uses the same pins as the Eval board.
Both Pi Pcio and ESP32 PicoW S3 are working fine on the 1.3" HAT. Therefore, the code for ESP32 S3 is good to use those pins.
However, there is serial to parallel on Eval board, therefore, only Pi Pico is working fine with RPI type setting. But no luck for ESP32 S3.
Thanks again,

PJ.

Oh, one mor thing.
The STM32 2.4.0 package supports the H7 mcu now.
I just got a new H7 board : https://www.aliexpress.com/item/1005001475058305.html?spm=a2g0o.order_list.order_list_main.24.d2f91802BLy0Wz
Checked the Processors/TFT_eSPI_STM32.c, seems that only F1,2,4,7 are supported right now.
Looking forward to the support of H7 mcu.

Best regards,
PJ.
