Re: 【求助】关于CBU的IO中断方式支持问题

CBU的中断不能支持双边沿触发中断,只能上升沿或者下降沿

Re: T2-U board ordering - shipping cost

The sample graffiti will be responsible for the freight, but the graffiti will not be responsible for the customs clearance costs, and the import declaration costs need to be borne by you

可以找下和你对接的客户经理,然后对接一下负责生产工具的开发同学。

Re: Readings not updating in Tuya app

The dp_update_all() function is only used to report all dp data after the device is powered on again. To report other data, call the my_device.mcu_dp_update() function at the required location.

Re: BK7231N 延时问题

我现在是用GPIO控制电机,同时定时器中断里进行超时计数,电机运动过程中一直检测目标霍尔信号,定时器计数超时或者检测到目标霍尔位置时电机停止。我这个需要达到毫秒级定时,电机动作优先级最高,联网只是附带功能,用于远程控制和读取设备状态。我贴出来的程序就是希望电机在运动过程中不要切换到其他任务,很明显这个还是有4ms左右误差

wifi类soc芯片由于首要工作是完成底层wifi相关的工作,所以底层WiFi硬件相关的中断优先级是最高的,上层的中断会被下层的中断打断导致时间不准。
