Description
ST Microelectronics STMPE Driver unit
The ST Microelectronics STMPE devices are a range of multi function chips that include GPIO, ADC, 4 wire touchscreen controller and PWM outputs in varying combinations. Many of the functions overlap so a pin can be used for example as a GPIO or a PWM but not both at once. The Touchscreen controller also consumes many of the GPIO pins in the models that support it. This driver supports the GPIO and Touchscreen functions of the following chips:
STMPE610 - 6 GPIO / 4-wire Touch / I2C / SPI
STMPE801 - 8 GPIO / I2C
STMPE811 - 8 GPIO / 4-wire Touch / I2C / SPI
STMPE1601 - 16 GPIO / 4 PWM / I2C
STMPE1801 - 18 GPIO / I2C
STMPE2401 - 24 GPIO / 3 PWM / I2C
STMPE2403 - 24 GPIO / 3 PWM / I2C
Note: A number of variations also support Keypad, Temperature and other features which are not currently handled by this driver.
