rt-thread / w601_iot_board Goto Github PK

rtt的ds18b20/dht11等基于单总线协议的package, 均使用rt_hw_us_delay进行us级延时

当前没有w60x官方实现的rt_hw_us_delay, 所以会回落到RT_WEAK默认实现, 也就是基于stm32的实现, 编译时必然报错.

希望能提供rt_hw_us_delay的官方实现

原因: 由于例程包比较大, github速度不太稳定, 建议提供基于 gitee 的镜像远端

这个nor flash可以干掉吗？我们做实际产品的，不会有外置flash

使用的是星通智联的TW-03模组，运行16_iot_wifi_manager例程时不停重启，已经更改过rtconfig.h里面的宏为#define SOC_W600_A8xx

先使用自带的AT固件，可以扫描到ap信息并连接，AT 固件log如下所示：

AT+CWLAP

+CWLAP:(4,"浜旀ゼ鏃犵嚎缃戠粶",-89,"24:69:68:ed:43:38",1)
+CWLAP:(4,"www.ghtech.cn",-51,"c8:3a:35:74:51:20",2)
+CWLAP:(4,"CMCC-QeZM",-59,"f8:48:fd:b1:c8:a8",2)
+CWLAP:(3,"PDCN",-52,"74:7d:24:ea:45:be",6)
+CWLAP:(0,"TP-LINK_F55C",-85,"50:bd:5f:73:f5:5c",6)
+CWLAP:(4,"yitai123",-93,"c8:3a:35:6d:6b:28",10)

OK

AT+CWJAP="www.ghtech.cn","123wu123"

WIFI CONNECTED
WIFI GOT IP

OK

然后下载此sdk的16_iot_wifi_manager例程，rtconfig.h中的宏已更改为w600 使用wifi scan命令 只扫描到一个ap, log如下：

扫描到的这两个ap 信道都是1 而且有时候能扫到 有时候又没有
