標題[問題] 新手發問-如何接收H36F信號
時間Sun May 10 21:52:10 2020
Hi, 各位先進
我想要讓我的Arduino可以接收H36F的訊號，讓我可以操作我的Arduino遙控車
經過一連串的爬文和研究，發現H36F的protocol是和E010一樣的(#1)
這顆遙控器是2.4G頻段，也有不少自製tx的範例，唯獨rx的研究相對稀少
我手邊有Arduino和一個nrf24l01，但我依照預定的地址嘗試讀取資料卻沒有獲得內容
想請問我在設定上發生甚麼問題嗎？
原始碼：
#include <SPI.h>
#include "nRF24L01.h"
#include "RF24.h"
#include "printf.h"
RF24 radio(9, 10);
#define MJX_PACKET_SIZE 16
#define MJX_RF_NUM_CHANNELS 4
#define MJX_ADDRESS_LENGTH 5
#define MJX_BIND_COUNT 150
#define MJX_PACKET_PERIOD 4000 // Timeout for callback in uSec
static const struct
{
u8 e010_txid[2];
u8 rfchan[MJX_RF_NUM_CHANNELS];
} e010_tx_rf_map[] = {{{0x4F, 0x1C}, {0x3A, 0x35, 0x4A, 0x45}},
{{0x90, 0x1C}, {0x2E, 0x36, 0x3E, 0x46}},

memcpy(rx_tx_addr, "\x6d\x6a\x77\x77\x77", sizeof(rx_tx_addr));
memcpy(mjx_rf_channels, "\x36\x3e\x46\x2e", sizeof(mjx_rf_channels));
printf_begin();
radio.begin();
while (!radio.isChipConnected())
delay(100);

void loop(void)

memset(buf, 0, 16);
radio.read(buf, 16);
int sum = 0;
for (int i = 0; i < 16; i++)
{
printf("%02x", buf[i]);
sum += buf[i];
radio.stopListening();
radio.setChannel(mjx_rf_channels[mjx_rf_chan++ / 2]);
mjx_rf_chan %= 2 * sizeof(mjx_rf_channels);
radio.startListening();
}
printf("\r");
if(sum)
printf("\n");
}
