RP2040 1.28 WAVESHARE TOUCH LCD

[tonluc123]

Hello,
I'm using this library successfully for almost a year now. I used GC9A01 & GC9A01 with touch and it is great. Lately I purchased a RP2040 1.28 WAVESHARE TOUCH LCD which I thought it would be easy to manage as it uses the same hardware , but ... no luck.
I tried the clock example and used the Dev-Device-Declaration#waveshare-rp2040-lcd-128 but nothing comes on the screen.
Does anybody had any experience with this module? Any help would be appreciated.

To be more accurate , this is the code
`

#include <Arduino_GFX_Library.h>
#define GFX_BL 25
Arduino_DataBus *bus = new Arduino_RPiPicoSPI(8 /* DC */, 9 /* CS */, 10 /* SCK */, 11 /* MOSI */, 12 /* MISO */, spi1 /* spi */);
Arduino_GFX *gfx = new Arduino_GC9A01(bus, 12 /* RST */, 0 /* rotation */, true /* IPS */);

void setup() {
 Serial.begin(115200);
  gfx->begin();
  gfx->fillScreen(BLUE);
}

void loop() {
  // put your main code here, to run repeatedly:

}

wild guess just not yet turn on backlight LED

Hello,
Thanks for your response. I included BL, but no change, see code bellow (maybe I did not implement it correct)
`#include <Arduino_GFX_Library.h>
#define GFX_BL 25
Arduino_DataBus bus = new Arduino_RPiPicoSPI(8 / DC /, 9 / CS /, 10 / SCK /, 11 / MOSI /, 12 / MISO /, spi1 / spi */);
Arduino_GFX gfx = new Arduino_GC9A01(bus, 12 / RST /, 0 / rotation /, true / IPS */);

void setup() {
pinMode(GFX_BL, OUTPUT);
digitalWrite(GFX_BL, HIGH);
Serial.begin(115200);
gfx->begin();
gfx->fillScreen(BLUE);
}

void loop() {
// put your main code here, to run repeatedly:

}`

I can see visually that bl is on
