24L01部分调试-TX模式下返回MAX怎么解决？

问答对人有帮助，内容完整，我也想知道答案 0 最近在研究OV7670+24L01的图像传输，搞了好多天了，现在分模块一步步来现在单独调24l01发现数据发不出去，返回max 大神们帮看看代码板子是 mini32 v3.0 备注的请跳过是OV7670的，已经屏蔽掉他们了但24L01还是不正常~ [C] 纯文本查看复制代码 #include "sys.h"#include "usart.h"#include "delay.h"#include "led.h" #include "lcd.h" #include "ov7670.h" #include "exti.h" #include "timer.h" #include "24l01.h" #include "spi.h"//ALIENTEK Mini STM32??·?°??©?????é9//?????·???é//?????§????www.openedv.com//?????????í??×????????????? extern u8 ov_sta;//??exit.c?????¨??extern u8 ov_frame;//??timer.c?????¨?? //?ü??LCD????void camera_refresh(void){u16 j , i; u16 color; u8 h_txbuf[31],l_txbuf[31]; u8 color_l,color_h; if(ov_sta==2){LCD_Scan_Dir(U2D_L2R);//????????,??×ó????
