简单粗暴的说: unit8_t,就是unsigned char, 数值范围是0-255, 占1个字节 unit16_t,就是unsigned int, 数值范围是0-65535, 占2个字节 unit32_t,就是unsigned long, 数值范围是0-4 294 967 295, 占4个字节编辑于 2022-05-09 20:48 Arduino ...
在Arduino编程中，理解和使用数据类型是关键步骤。其中，uint8_t、unit16_t和unit32_t分别代表不同长度和数值范围的无符号整型数据。首先，我们来了解一下uint8_t。它实际上就是unsigned char类型，用于表示一个无符号的8位整型数，其数值范围从0到255，占用一个字节的内存空间。紧随其后的是unit16_...
Introducing Seeed Studio’s very own line of sensor modules – the Grove system. It consists of a base unit and various modules with standardized connectors. The Base unit allows easy connection of any input or output from the Grove modules. And every Grove module typically addresses a single ...
An even more accurate solution could be to use a dedicated timer with an input capture unit, that can store the timestamp of a change on the DIO0 pin (the only one that is timing-critical) entirely in hardware. Experience shows that this is not normally required, so we leave this as ...
