The Small C compiler translates a subset of the C language into assembly language. It runs under PC/MS-DOS 2.1 and later. Small C is compatible with the Microsoft and Small Mac assemblers. Small C takes full advantage of the ability of these assemblers to generate relocatable object code, to maintain libraries of relocatable modules, and to link separately compiled program modules. It supports a small memory model with one code and one data/stack segment.

This directory contains the memtest 8051 firmware for the Anchor Chips EZ-USB chip. The purpose of this software is to test the different memory segments in the Ez-Usb chip. This example will output the string "good" on the 7 segment LED if the mem test passes, or it will output the first address where the memtest fails.

VDSP++打开。This directory contains an example ADSP-BF537 RTC project that does a basic blink routine and then puts the part in deep sleep mode to be woken up from a RTC Stopwatch Event. Once woken up, the RTC is reconfigured to toggle the EZ KIT LEDs using RTC second, minute, hour, and day interrupts.
