freescale ect 捕获中断程序，程序已经经过调试，成功。-freescale ect capture interrupt program, the program had already been debugging and successfully.

本程序简单的示范了如何使用ATMEGA16的定时器 AVR定时器的要点介绍 T0工作于CTC模式，输出1KHz/2KHz 50％占空比的方波 T1工作于快速PWM模式兼输入捕捉 T2工作于相位修正PWM模式，输出490Hz的8bit PWM波-This procedure simple demonstration how to use the ATmega16 timers AVR timer T0 introduce the main points of work in CTC mode, the output 1KHz/2KHz 50 duty cycle square wave T1 work in fast PWM mode Input Capture and work on phase-corrected T2 PWM mode, the output of 8bit PWM wave 490Hz

The objective is to set up SPI communication between VTI Technologies digital pressure sensor component and an MCU of an application device ATMEGA16L. In this code example: ?The MCU is configured ?SCP1000-D01 is initialized and configured ?The high resolution measurement mode is activated ?Temperature and pressure information is read always when the DRDY pin is in high state Please refer to the document "SCP1000 Product Family Specification 8260800" for further information on SCP1000 register addressing and SPI communication.

这一项目中 C.pwm 有示例您可以用 LED，直流电动机的界面 PWM。 控制器： PIC18f44k22 时钟： 4 兆赫。 信： 5V

SAM9261 BasicMMU Example code with ADS1.2 (163 kB) The goal of this project is to show how to use a PC100 SDRAM and the MMU to perform a rating with a 100MHz Bus Clock. The rating is based on Dhrystone 2.1. It shows the rate when I+D Caches are disabled or enabled, with or without MMU and I Cache is disable or enabled, with or without MMU. -SAM9261 BasicMMU Example code with ADS1.2 (163 kB) The goal of this project is to show how to use a PC100 SDRAM and the MMU to perform a rating w praxiology a 100MHz Bus Clock.
