JC8048W550 ST7262 no display with V1.4.6

[hape65]

hi thx for your work to get all the displays work. But unfortunately the described board above can be compiled with the PDQgraphicstest.ino but there is no picture on the screen. Could i do a check on something else? The board has a screen programmed so it works. this are the pins: Serial Number Pin Notes Connect
1 IO8 U1RXD DB1(B) b0
2 IO3 DB2(B) b1
3 IO46 DB3(B) b2
4 IO9 DB4(B) b3
5 IO1 DB5(B) b4
6 IO39 HSYNC x
7 IO41 VSYNC x
8 IO40 DE x
9 IO5 DB6(G) g0
10 IO7 DB8(G) g2
11 IO15 DB9(G) g3
12 IO16 DB10(G) g4
13 IO4 DB11(G) g5
14 IO45 DB13(R) r0
15 IO48 DB14(R) r1
16 IO47 DB15(R) r2
17 IO21 DB16(R) r3
18 IO43 U0TXD TX
19 IO44 U0RXD RX
20 IO0 BOOT I2S-BCLK/L3
21 IO18 I2S-LRCLK/L2
22 IO10 SPICS0 TF(CS)
23 IO11 SPID TF(MISO)
24 IO17 U1TXD IS2-DIN/L1
25 IO38 TP_CS
26 IO21 BL_C
27 IO37
28 IO36
29 IO35
30 IO14 DB17(R) r4
31 IO20 USB_D+ TP_SCL
32 IO12 SPICLK TF(SCK)/TP_CLK
33 IO13 SPIQ TF(MOSI)
34 IO42 PCLK x
35 IO6 DB7(G) g1
36 IO19 USB_D- TP_SDA

so this same with this definition

Do you have any idea what i can test anymore?

regards hape

BL?

[hape65]

GFX_BL is set to 2 or what do you mean?

[moononournation]

is it the back light pin should be 21?

[hape65]

i found an error if i uncomment the line

define ESP32_4827S043

and do nothing else on PDQgraphicstest i get C:\Users\hape\Documents\Arduino\libraries\GFX_Library_for_Arduino\examples\PDQgraphicstest\Arduino_GFX_dev_device.h:119:1: error: 'Arduino_ESP32RGBPanel' does not name a type; did you mean 'Arduino_ESP32S2PAR8Q'?

[moononournation]

use arduino-esp32 v2

[hape65]

ok one step ahead now the sketch comes up at runtime with this:

Arduino_GFX PDQgraphicstest example!

please follow your ESP32 version set the flash size, speed and PSRAM type

so finally it works thx a lot to you - is https://paypal.me/moononournation your paypal?
