MSP430把nRF905的“TRX_CE”引脚置为高电平,“TX_CE引脚拉为低电平后就刻蚀结社数据,本设计中CPU在设定的35s内一直判断Nrf9051“dr”引脚是否便变高个,若为高则证明接收到了有效数据,可以退出接收模式,弱一致没有接受2到,待时间到时也退出接接受是模块,退出后在待机模块,CPU通过SPI总线把NRF905内部的接收数据寄存器中数据读出,即接收道德有效数据。 便携接受部分程序时,有一点应该注意,很多资料中都没有提到,就是CPU在MOSI信号线上发出读命令字节后“MISO”信号线上nRF905会自动返回一字节数据,本本身的状态寄存器信息,后续的接收数据并不会自动跟着输出,只有CPU在MOSI上输出一个字节(可以是随意值),nRF905才会在“MISO”上返回一个字节,CPU再发,nRF905再满会,直到读完为止。

TOOL (Tiny Object Oriented Language) is an easily-embedded, object-oriented, C++-like-language interpreter. The language, and indeed a significant part of the core of the TOOL engine, is based on the BOB project, a work that was originally developed by David Betz covered in previously published issues of dr. Dobb s Journal.

This example describes how to use the ADC and DMA to transfer continuously converted data from ADC to a data buffer. The ADC is configured to converts continuously ADC channel14. Each time an end of conversion occurs the DMA transfers, in circular mode, the converted data from ADC1 dr register to the ADC_ConvertedValue variable. The ADC1 clock is set to 14 MHz.
