The latest version of the 3.5-inch screen is version 2.2. The touch drive IC is different.

Version 2.0

TFT_MISO is pin 12;

Touch_CS is pin 33.

Version 2.2:

TFT_MISO is pin 33;

Touch_CS is pin 12.

Therefore, the corresponding pin numbers need to be modified in the code, and the TFT_eSPI library also needs to be modified accordingly.

The latest version of the 5-inch and 7-inch screens is version 3.0, which adds the chip PCA9557 to increase timing control. Therefore, you need to add the PCA9557 library to make the touch work properly.

Code: https://github.com/Elecrow-RD/CrowPanel-ESP32-Display-Course-File/tree/main/CrowPanel_ESP32_Tutorial/Code

①Add the PCA9557 library:

#include <PCA9557.h>

②Define the PCA9557 object:

PCA9557 Out;

③Control with RESET and EN to meet the timing requirements:

Wire.begin(19, 20);
Out.reset();
Out.setMode(IO_OUTPUT); //Set to output mode
Out.setState(IO0, IO_LOW);
Out.setState(IO1, IO_LOW);
delay(20);
Out.setState(IO0, IO_HIGH);
delay(100);
Out.setMode(IO1, IO_INPUT);

Because "SmartView" has been registered by others, we now officially name the HMI series CrowPanel

📙February 2024

1.Product Name change to SmartView Display

2.Hardware changes:

• Silkscreen: 1. From "Wizee ESP32" to "ESP32 Display-xinch"; 2.From "WZxxx" to "DISxxx"
• All sizes of screens have added battery charging circuits. Connect the battery to the BAT interface and you can charge the battery through the USB-C interface.
• There is no need to manually press the boot button to enter the burning mode for all screen sizes. After you click download in the compiler, the board will automatically enter the burn-in mode.
• After the program download is completed, the program can be automatically run.
• For 3.5-inch display, the chip is changed from ESP32-WROOM-32-N4 to ESP32-WROVER-B, PSRAM is changes to 8MB
• For 5.0, 7.0-inch display, there's I2C port added

Attempting tutorial 4 in the Elecrow Tutorial series. Code compiles and uploads just fine but the screen stays blank and I get the following error on the serial monitor on repeat.

Some googling suggests this is a conflict between a GPIO and the flash (not sure if that's actually the cause of the issue or not), but I'm using the gfx_conf.h from the tutorial files. I've tried different USB ports and have it plugged into a powered USB hub. Not sure what other troubleshooting steps to take at this point.

Files attached for convenience.
I am completely new to this. Please let me know if I can provide any additional information that might prove helpful.

What i realized is that while all these use the Wire.h library, when using LovyanGFX a different i2c library is internally used to drive the GT911 capacitive touch driver ic breaking the Wire.h functionality.

Is there a way to either use Wire.h for LovyanGFX or disable the touch functionality for a "brief" time freeing up the i2c bus or do I have to rewrite every module library to use the same library LovyanGFX uses?
Thanks in advance.

Now I have to try CrowPanel Advanced 7inch ESP32-P4 HMI AI Display 1024x600
But unfortunately I found examples only for IDF - it’s not suitable for me, I don't plan to learn new framework )

Is it possible to get PlatformIO code examples for CrowPanel Advanced 7inch ESP32-P4 like for CrowPanel-5.0-HMI-ESP32?
