EPICS High Resolution Timer and Alarm Clock Library.
An EPICS high resolution timer and alarm clock library for Linux and RTEMS.
EPICS is the Experimental Physics Industrial Control System framework.
This library supports Linux by utilizing POSIX functions.
For RTEMS VME-Bus systems it supports the CPU cards mvme2100, mvme5500 and mvme6500 ("beatnik" board support).
This is the Linux kernel driver for the stmpe2401 and stmpe2402 GPIO expanders from ST Microelectronics. These i2c chips support up to 24 extra GPIO lines, have 3 programmable PWM outputs, an integrated keypad input, and rotator input controllers.
