Antonio Quevedo / TSIHW

This is a VERY low-level library for controlling the TSI hardware module in a KL25 microcontroller. The programmer creates the TSI object passing basic parameters, and selects the active channels. Then, a scan on a given channel can be started, and the raw result can be read.
