AppBuilder is a free tool specific to Silicon Labs’ Precision32 MCUs which enables developers to quickly and graphically choose the peripheral mix, select peripheral properties, set up clocking modes, and customize pin-out; all without reading the data sheet. AppBuilder can even generate source code. This allows developers to get their MCU up and running quickly without having to spend days slogging through the data sheet and register settings. AppBuilder can be downloaded free of charge at: https://www.silabs.com/products/mcu/32-bit.
