AT91SAM9263的Keil下的CAN总线的例程文件(AT91SAM9263 under the CAN bus of the Keil routine document)

Foreword The use of reprogrammable memory technology in vehicle electronic control units (ECUs) has increased in recent years, and is expected to continue in the future. Use of this technology has increased the flexibility of being able to use a single ECU hardware part to be used in many different vehicle configurations, with the only difference being the software and calibrations programmed into the unit. Reprogramming of those ECUs in the service environment also allows for ease of field modification of system operation and calibrations. Variations in reprogramming capability and the multiple tools necessary to reprogram vehicles are a burden on aftermarket repair facilities that service different makes of vehicles.

此程序用于430单片机，通过单片机采样波形，再对此波形进行快速傅里叶变换，并将变换的结果用12864显示出来(This program is used 430 microcontroller, through the microcontroller sampled waveform, then this waveform fast Fourier transform, and the result of the transformation is displayed with 12864)
