模仿稚晖君MonoUI风格的超丝滑菜单,使用EC11旋转编码器控制。
文档中这一行有提到过使用旋钮质量不好的话会有问题
我在参考Arduino
关于attachInterrupt
函数的文档时看到有这样一段描述:
Inside the attached function, delay() won’t work and ... ... . You should declare as volatile any variables that you modify within the attached function. See the section on ISRs below for more information.
以及:
Since delay() requires interrupts to work, it will not work if called inside an ISR.
请问一下是否意味着btn_scan()
函数中delay()
没有生效导致部分旋钮会出现问题,以及btn
的struct
声明是否应该使用volatile
关键字修饰以保证变量修改操作的原子性,即如下代码:
struct
{
uint8_t id;
// other fields
} volatile btn;
或者:
volatile struct
{
uint8_t id;
// other fields
} btn;
