c8t6用SPI1连接nrf24l01出现问题

gonglei111 · 发表于 2020-8-30 19:15:23

程序是用的原子哥的无线通信改的端口

#define NRF24L01_CE PGout(8)
#define NRF24L01_CSN  PGout(7)
#define NRF24L01_IRQ  PGin(6)

SPI2改成了SPI1

第一关检测就过不了
检测不到nrf24l01的存在
测了一下电平，在同样执行完初始化之后，战舰V3（能正常使用nrf24l01）的八个引脚电平跟我自己画的c8t6板子的引脚电平,MOSI引脚的电平是不一样的，原子哥的是高电平，我的是低电平。
我觉得有可能是我在根据原子哥的程序改成SPI1的时候哪里出现了纰漏，但是花了两天时间也没找出什么错误的地方，希望各位大佬百忙之中帮忙看一眼，十分感谢

这是我改了之后24l01的c文件

#include "24l01.h"
