关于CC1101的sleep模式下,电流是nA级,但是我现在调用函数Sleep后,电流在15微安左右。下面是进入sleep模式的函数。主程序在对CC1101进行初始化后,就一直执行while(1);语句。
/* 进入 sleep模式 */ void CC1101_SLEEP(void) [ halSpiStrobe(CCxxx0_SIDLE); halSpiStrobe(CCxxx0_SXOFF); halSpiStrobe(CCxxx0_SPWD); Delayms(1); CSN = 1; ] 下面的是我寄存器配置的值 载波频率是433MHz 波特率是100Khz typedef struct S_RF_SETtiNGS [ INT8U FSCTRL2; //自已加的 INT8U FSCTRL1; // Frequency synthesizer control.
