Microbit上Micropython命令time_pulse_us是用于测量脉冲宽度的函数。它可以返回一个引脚上脉冲的宽度,单位为微秒。 该命令的语法如下: 代码语言:txt 复制 time_pulse_us(pin, pulse_level, timeout_us) 参数说明: pin:要测量脉冲的引脚号。 pulse_level:脉冲的电平,可以是0(低电平)或1(

I have altered how the RGBBus driver works. Due to low framerates from LVGL needing to render the whole screen each time a small change is made and LVGL also having to keep the 2 frame buffers in sync I have decided to try and bring a little bit of my coding ability to the show ...
