大家好,我有个问题想请教下大家。在NRF24L01无线通信这个实验中,原来的代码是用通道0做数据的接收和发送,我把原子哥的代码稍作修改了下,想改用通道2做数据的接收和发送,下面是我做修改的通道程序,和原来的程序对比的图片,同样的方法修改为通道一就没问题,改为通道2就是调不通,大家帮我看下具体问题在哪儿,thank you!这是原子哥原来的代码,
const u8 TX_ADDRESS[TX_ADR_WIDTH]={0x34,0x43,0x10,0x10,0x01}; const u8 RX_ADDRESS[RX_ADR_WIDTH]={0x34,0x43,0x10,0x10,0x01}; void NRF24L01_RX_Mode(void) { NRF24L01_CE=0; NRF24L01_Write_Buf(NRF_WRITE_REG+RX_ADDR_P0,(u8*)RX_ADDRESS,RX_ADR_WIDTH); NRF24L01_Write_Reg(NRF_WRITE_REG+EN_AA,0x01); NRF24L01_Write_Reg(NRF_WRITE_REG+EN_RXADDR,0x01); NRF24L01_Write_Reg(NRF_WRITE_REG+RF_CH,40); NRF24L01_Write_Reg(NRF_WRITE_REG+RX_PW_P0,RX_PLOAD_WIDTH); NRF24L01_Write_Reg(NRF_WRITE_REG+RF_SETUP,0x0f); NRF24L01_Write_Reg(NRF_WRITE_REG+CONFIG, 0x0f); NRF24L01_CE = 1; } void NRF24L01_TX_Mode(void) { NRF24L01_CE=0; NRF24L01_Write_Buf(NRF_WRITE_REG+TX_ADDR,(u8*)TX_ADDRESS,TX_ADR_WIDTH); NRF24L01_Write_Buf(NRF_WRITE_REG+RX_ADDR_P0,(u8*)RX_ADDRESS,RX_ADR_WIDTH); NRF24L01_Write_Reg(NRF_WRITE_REG+EN_AA,0x01); NRF24L01_Write_Reg(NRF_WRITE_REG+EN_RXADDR,0x01); NRF24L01_Write_Reg(NRF_WRITE_REG+SETUP_RETR,0x1a); NRF24L01_Write_Reg(NRF_WRITE_REG+RF_CH,40); NRF24L01_Write_Reg(NRF_WRITE_REG+RF_SETUP,0x0f); NRF24L01_Write_Reg(NRF_WRITE_REG+CONFIG,0x0e); NRF24L01_CE=1; } 下面是我修改后的代码,麻烦大家帮我看下那个地方出问题了,纠结了好长时间: const u8 TX_ADDRESS[TX_ADR_WIDTH]={0x43,0x10,0x10,0x03,0x02}; const u8 RX_ADDRESS_P0[RX_ADR_WIDTH]={0x43,0x10,0x10,0x03,0x00}; const u8 RX_ADDRESS_P1[RX_ADR_WIDTH]={0x43,0x10,0x10,0x03,0x01}; const u8 RX_ADDRESS_P2[RX_ADR_WIDTH]={0x43,0x10,0x10,0x03,0x02}; const u8 RX_ADDRESS_P3[RX_ADR_WIDTH]={0x43,0x10,0x10,0x03,0x03}; const u8 RX_ADDRESS_P4[RX_ADR_WIDTH]={0x43,0x10,0x10,0x03,0x04}; const u8 RX_ADDRESS_P5[RX_ADR_WIDTH]={0x43,0x10,0x10,0x03,0x05}; void NRF24L01_TX_Mode(void) { NRF24L01_CE=0; NRF24L01_Write_Buf(NRF_WRITE_REG+TX_ADDR,(u8*)TX_ADDRESS,TX_ADR_WIDTH); NRF24L01_Write_Buf(NRF_WRITE_REG+RX_ADDR_P0,(u8*)RX_ADDRESS_P2,RX_ADR_WIDTH); NRF24L01_Write_Reg(NRF_WRITE_REG+EN_AA,0x01); NRF24L01_Write_Reg(NRF_WRITE_REG+EN_RXADDR,0x01); NRF24L01_Write_Reg(NRF_WRITE_REG+SETUP_RETR,0x1a); NRF24L01_Write_Reg(NRF_WRITE_REG+RF_CH,40); NRF24L01_Write_Reg(NRF_WRITE_REG+RF_SETUP,0x0f); NRF24L01_Write_Reg(NRF_WRITE_REG+CONFIG,0x0e); NRF24L01_CE=1; } void NRF24L01_RX_Mode(void) { NRF24L01_CE=0; NRF24L01_Write_Buf(NRF_WRITE_REG+RX_ADDR_P2,(u8*)RX_ADDRESS_P2,RX_ADR_WIDTH); NRF24L01_Write_Reg(NRF_WRITE_REG+EN_AA,0x04); NRF24L01_Write_Reg(NRF_WRITE_REG+EN_RXADDR,0x04); NRF24L01_Write_Reg(NRF_WRITE_REG+RF_CH,40); NRF24L01_Write_Reg(NRF_WRITE_REG+RX_PW_P2,RX_PLOAD_WIDTH); NRF24L01_Write_Reg(NRF_WRITE_REG+RF_SETUP,0x0f); NRF24L01_Write_Reg(NRF_WRITE_REG+CONFIG, 0x0f); NRF24L01_CE = 1; } |

改为
const u8 RX_ADDRESS_P0[RX_ADR_WIDTH]={0x43,0x10,0x10,0x03,0x00}; const u8 RX_ADDRESS_P1[RX_ADR_WIDTH]={0x01,0x10,0x10,0x03,0x00}; const u8 RX_ADDRESS_P2[RX_ADR_WIDTH]={0x02,0x10,0x10,0x03,0x00}; const u8 RX_ADDRESS_P3[RX_ADR_WIDTH]={0x03,0x10,0x10,0x03,0x00}; const u8 RX_ADDRESS_P4[RX_ADR_WIDTH]={0x04,0x10,0x10,0x03,0x00}; const u8 RX_ADDRESS_P5[RX_ADR_WIDTH]={0x05,0x10,0x10,0x03,0x00}; |

您好,我刚才试了试,把你的这个复制到代码中,并把const u8 TX_ADDRESS[TX_ADR_WIDTH]={0x43,0x10,0x10,0x03,0x02}; 改为和const u8 RX_ADDRESS_P2[RX_ADR_WIDTH]={0x02,0x10,0x10,0x03,0x00};一样,想用通道2来接收,还是发送失败,
