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.

📕June 2024

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

🚀 Looking for a way to control your devices from a distance? Elecrow terminal is a microcontroller based on the ESP32 master. It adopts an Xtensa 32-bit LX7 dual-core processor with a main frequency of up to 240Mhz, supports 2.4GHz Wi-Fi and Bluetooth 5 (LE), and can easily handle common edge terminal device application scenarios, such as industrial control, agricultural production environment detection and processing, intelligent logistics monitoring, smart home scenarios and more. 👏🏻

🚩 Detailed tutorial (LVGL GUI development step-by-step guide) 👇

I recently bought a couple of Elecrow ESP32 display devices, and I'm having some issues uploading a firmware image onto them. I have both an ESP Terminal and an ESP32 with 5-inch display, and both seem to behave the same way.

To upload a firmware image to the board, the wiki says to:

This manually puts the board in "Firmware Download Mode", but it's very impractical to have to do this every single time I make a small change to my code. On the ESP Terminal the buttons are very close together in a recessed slot and having to do this for every small code change makes it much more difficult to use than other similar products (e.g. WT32-SC01 or WT32-SC01 Plus).

How can I use this hardware like almost all other ESP32 boards, where you can just press "Upload sketch" in Arduino IDE or "Upload and monitor" in PlatformIO or esptool.py write_flash, and it immediately uploads it?

From what I understand, for this to happen the board would need to have the DTR and RTS pins of the USB-to-serial converter to be connected to the ESP32's EN and GPIO0 pins respectively, but I don't see this on the schematic linked at the bottom of the product page. I see EN connected to the FT6236's reset pin, but not to DTR, and I don't see anything connected to RTS. This makes me wonder if it's even possible with this hardware…

I'd be very grateful if someone here knew of a way to achieve this. I contacted Elecrow's techsupport@… email about it but haven't heard anything back.

Modify the following code:
