Crowpanel 5Zoll Advance black screen after flashing example
I used the following example : platfromIO_70_50_43
After uploading it to my CrowPanel 5Zoll Advaned V1.1 i get only a black screen.
Terminal output:
I2C devices detected (0x30, 0x5D)
command 0xFF Sent successfully
Any idea what i have to consider? Same pgm runs on 4.3 Zoll

example is from your google drive
Hi jst,
It's possible that the hardware version is incompatible. Your device's hardware version is v1.1. Please try the tutorials and sample programs in the link below:

Warm regards,
I used the example from Elecrow for PlatformIo and the CrowPanel 5" andvanced Version 1.1. The directory there is "..\4.3V1.1__5.0V1.2__7.0V1.3\platfromIO_70_50_43".
But now I found the problem by myself. Your code is wrong! There on Line 105/106:
// Start sending command 0 to address 0x30
sendI2CCommand(0); // 0 is the brightest backlight. / 245 backlight off (0-245)
But this doesn't work! As I found in another place: x10 is the brightest backlight. This way it works.
You should adjust the code for V1.1
P.S The Code described in the above Link is not the same but also wrong.
