ESP32 Display Update History
Here we record the changes to the esp32 displays
📕March 2024
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
3.Demo code changes
For 5-inch HMI:
- Display Drive Library: LovyanGFX
