+The STMPE811 driver comes with two different #defines to perfectly fit +your application: + + +STMPE811_NO_GPIO_IRQPIN +This Macro is meant to be set in your board file. When you set this macro to +TRUE, the GINPUT module will not use the IRQ lane which might be connected +to a GPIO pin to recognize interrupts by the STMPE811 controller. This +costs a few more I2C calls. +When the interrupt IRQ pin is connected to a GPIO of your MCU, set this +macro to FALSE. + + +STMP811_SLOW_CPU +If you have a slow CPU and you need to take care of your resources, you can +set this macro TRUE. This will save some IRQs and therefore a few I2C calls. +The disadvantage is a little higher response time. +If you don't want to draw continious lines on your display, it's recommended +to set this to TRUE anyways. + |
