M5Paper 2020 V0.0.
Overview M5 Paper is a touchable ink screen controller device. This document will demonstrate how to use the device to test basic WIFI and Bluetooth functions. Development environment Arduino IDE Go to https://www.arduino.cc/en/main/software to download the Arduino IDE corresponding to your operating system and install it.
https://m5stack.oss-cnshenzhen.aliyuncs.com/resource/arduino/package_m5stack_index.json Search for "M5Stack" in the board management and download it.
After uploading the program to the development board, open the serial monitor to view the WiFi scan results
Bluetooth Demonstrate how to use classic Bluetooth to send messages through Bluetooth and transmit them to the serial port for printing. After uploading the program to the development board, use any Bluetooth serial debugging tool to pair and connect, and send messages.
After the debugging tool sends a message, the device will receive the message and print it to the serial port.
Overview M5 Paper is a touchable ink screen controller device, the controller adopts ESP32-D0WD. An electronic ink screen with a resolution of 540*960 @4.7" is embedded on the front, supporting 16-level grayscale display. With GT911 capacitive touch panel, it supports two-point touch and multiple gesture operations. Integrated dial wheel encoder, SD card slot, and physical buttons. An additional FM24C02 storage chip (256KB-EEPROM) is mounted for power-off storage of data.
Rich expansion interface Main Hardware ESP32-D0WD ESP32-D0WD is a System-in-Package (SiP) module that is based on ESP32, providing complete Wi-Fi and Bluetooth functionalities. The module integrates a 16MB SPI flash. ESP32-D0WD integrates all peripheral components seamlessly, including a crystal oscillator, flash, filter capacitors and RF matching links in one single package. 4.7” Ink screen model EPD-ED047TC1 Resolution 540 * 940 Display area 58.32 * 103.
