CHSC6540 - Touch screen controller
The CHSC6540 is the touch screen controllers of the M5Stack Tough.
Documentation
- More information on the touch controller, unfortunately, the datasheet isn't available from the manufacturer. Only an incomplete shadow copy from a content provider here.
Usage
Important: make sure you properly setup the I2C pins especially for ESP32 before creating the I2cDevice
, make sure you install the nanoFramework.Hardware.ESP32 nuget
:
//////////////////////////////////////////////////////////////////////
// when connecting to an ESP32 device, need to configure the I2C GPIOs
// used for the bus
Configuration.SetPinFunction(21, DeviceFunction.I2C1_DATA);
Configuration.SetPinFunction(22, DeviceFunction.I2C1_CLOCK);
For other devices like STM32, please make sure you're using the preset pins for the I2C bus you want to use.
Note: this sample requires a M5Stack Tough. If you want to use another device, just remove all the related NuGet packages.
