Integrating Touch Sensing Software (TSS 3.0.1) on Kinetis L Using GPIO Method
نویسنده
چکیده
The Touch Sensing Software (TSS) solution transforms a standard Freescale microcontroller into a proximity capacitive touch sensor controller. In TSS 3.0 and higher versions, the touch sense library enables capacitive sensing not only for the entire Freescale S08, ColdFire V1 family and ARM®CortexTM-M4 Kinetis, but also ARM Cortex-M0+ Kinetis L family of microcontrollers. In the TSS 3.0.1 Library, a demo called FRDMKL25Z_DEMO is offered using TSI method based on FRDM-KL25Z board. The FRDM-KL25Z is an ultra-low-cost development platform enabled by Kinetis L Series KL1 and KL2 MCU families built on ARM Cortex-M0+ processor. In this application note, the demo FRDMKL25Z_DEMO is mostly reused and and finally shows touch sensing with GPIO method, not TSI method. This is a good example of integrating TSS for those MCUs that have no TSI module such as S08 or KL02.
