MSP430把nRF905的“TRX_CE”引腳置為高電平,“TX_CE引腳拉為低電平后就刻蝕結社數(shù)據(jù),本設計中CPU在設定的35s內一直判斷Nrf9051“DR”引腳是否便變高個,若為高則證明接收到了有效數(shù)據(jù),可以退出接收模式,弱一致沒有接受2到,待時間到時也退出接接受是模塊,退出后在待機模塊,CPU通過SPI總線把NRF905內部的接收數(shù)據(jù)寄存器中數(shù)據(jù)讀出,即接收道德有效數(shù)據(jù)。 便攜接受部分程序時,有一點應該注意,很多資料中都沒有提到,就是CPU在MOSI信號線上發(fā)出讀命令字節(jié)后“MISO”信號線上nRF905會自動返回一字節(jié)數(shù)據(jù),本本身的狀態(tài)寄存器信息,后續(xù)的接收數(shù)據(jù)并不會自動跟著輸出,只有CPU在MOSI上輸出一個字節(jié)(可以是隨意值),nRF905才會在“MISO”上返回一個字節(jié),CPU再發(fā),nRF905再滿會,直到讀完為止。

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.
