EasyLoader
What is EasyLoader?
-
EasyLoader is a simple and fast program burner. The EasyLoader on each product page provides a product-related case program, which can be burned to the main control through simple steps, and a series of functional verifications can be carried out.
- After downloading the software, double-click to run the application, connect the M5 device to the computer through the data cable, select the port parameters, and click "Burn" to start burning. (When burning for M5StickC, please Set the baud rate to 750,000 or 115200)
-
At present, EasyLoader is only applicable to Windows operating system, compatible with M5 system, and uses ESP32 as the control core host. You need to install the CP210X driver before burning for M5Core (if you use M5StickC as the controller, you don’t need to install it) [click here to view Driver installation tutorial](/en/uiflow/uiflow_web#Install the serial port driver)
