48 ways to use a charge time measurement unit

The Charge Time Measurement Unit (CTMU) found on some PIC microcontrollers is a peripheral to interface with capacitive touch sensors. It can also be used in other functions, and the app note linked above provides a few ideas: In a nutshell, the CTMU is an on-chip constant-current source, surrounded by digital circuitry to precisely control […]

App Note: Versatility of CTMU

This Microchip application note explores the many uses for the Charge Time Measurement Unit (CTMU). CTMU is a flexible analog module that provides accurate differential time measurement between pulse sources, as well as asynchronous pulse generation. Together with other on-chip analog modules, the CTMU can be used to precisely measure time, measure capacitance, measure relative […]
