'''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:

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.
