- Use your phone to Wi-Fi scan an AP name start with 'm5stack-' and click to connect this AP.
- Open up web browser on your phone and visit 192.168.4.1
- Then here comes the picture. Video is about 5-6 frames per seconds. not super fast.
EasyLoader
1.EasyLoader is a simple and fast program burner. Every product page in EasyLoader provides a product-related case program. It can be burned to the master through simple steps, and a series of function verification can be performed. .
- 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, click "Burn" to start burning. (For M5StickC burning, please Set the baud rate to 750000 or 115200)

FAQ
HARDWARE RELATED
Q1: How do I remove the speaker floor noise when the M5Core is on or running?
Execute the following statement in Setup() of the Arduino program
Q2: How does M5Core2 stack modules?
When M5Core2 is stacked with other M5 modules, you need to remove the battery base of Core2, which does not support module stacking.
Q3: A timeout error is displayed when uploading the program to the device
Reason and solution: The power supply current of the port is insufficient, which can cause the device to not enter the download mode normally. You can try to connect a capacitor (>0.1uF) between the RST pin and the GND pin, or when uploading the program, set the G0 Short-circuit to GND, so that G0 can be set to a low level state normally
Q4: How to solve the phenomenon of automatic signal triggering of M5Core button A
Add the header file #include <driver/adc.h> and the function adc_power_acquire(); in the Arduino program
Q5: M5 device battery life
The battery life of the controller is affected by various factors such as battery capacity, operating status, and load, so there is no fixed value. Reducing the load and adopting a sleep strategy can effectively increase the battery life.
Q6: Can multiple modules with batteries be stacked at the same time?
Support multiple stacks, the total capacity of the batteries in parallel increases, and the voltage remains unchanged. However, since the discharge of each battery is not balanced during use, there is a voltage difference between the batteries, which may cause the battery to charge backwards. .(will lose part of the battery capacity)
Q7: M5 master supports WiFi connection to 5G frequency band
ESP32 module currently does not support WiFi in 5G band, only 2.4G.
Q8: The RS485 device cannot communicate normally/data is garbled. Packet loss, etc.
Confirm whether the TX/RX pin on the TTL side of the pin is correct, try to add two 120Ω terminal resistors at the beginning and end of the device line to reduce signal reflection interference

Q10: M5 camera image blur, how to adjust the focal length
Rotate the lens to adjust the focal length within a certain range

Q1: How to read the programmed firmware?
Use esptool to read the flash content of esp32 and export the bin file. Refer to the detailed operation
Q2: Several solutions for esp32 board download failure in Arduino IDE board management
Restart the Arduino IDE, the computer uses the mobile AP mobile network to download.
Q3: Arduino SPIFFS file upload operation
Refer to the Github link below, use arduino-esp32fs-plugin for file upload
Q4: When M5Burner burns firmware, an error pop-up window or exception occurs
Check if the COM of the corresponding device is selected and if the M5Burner is the latest version
Q5: Does the M5 master device support multi-language display (Chinese, English, Japanese, Russian, etc.)?
UIFlow users can switch the Label font to Unicode, Arduino users can use the Chinese font library provided in the M5GFX driver library
Q6: The program cannot load the SD card normally
Confirm whether the SD card format is FAT32, and no partitions exist.
Q7: How to use Bluetooth, HTTP, SD, WebServer, FreeRTOS and other features in Arduino IDE
You can refer to the following link for other ESP32 users to share the case program
Q8: How to download programs for STAMP C3U
STAMP C3U enters program download mode operation: 1. Long press the center button (G9) of STAMP C3U when the power is off. 2. Connect to the computer, after the port is successfully identified, program burning.
Q9: How STAMP C3U defines UART0 output mode
By default, USB CDC is not enabled, the serial port output started by C3U will be output through the default pins (G20, G21) of UART0. If you want to output through USB, please use the IDE to output Its USB CDC option is enabled. (Arduino users can enable it through Tools->USB CDC on Boot-Enabled. For IDF users, please refer to the ESP IDF official documentation.)
Q10: Unable to connect to UIFlow Desktop IDE
Refer to the UIFlow documentation of the corresponding device to check whether the device has entered the USB programming mode.
