Interrupts are a relatively advanced topic in microprocessor programming. Arduino code for TTP229 Touch 16 button Arduino Code for TTP229 16 Key Touch button I could not find the arduino library code for TTP229 keys and hoping this will help others who have bought this item from ebay to be able to use the keyboard. A small program is developed which reads the status of a LaunchPad push button. This board is capable of running all the uLisp examples. The MSP432 is an ARM Cortex M4F, low power, and planned for production later this year. Click the "Preview" button in the top-right corner. Save this image, as we will need it all time while programming our MSP430 through Energia. When I run it I change the voltage on.
