Using 2B93's PWM for DC output, the experiment found that when the duty cycle is 100%, the DC voltage should theoretically be 3.3V, but in reality the DC output voltage is 0V, and the PWM waveform at ...
Question: If we define: #define FLAG 0x01, does it occupy memory? How much memory does it occupy? Another thing is that 430 itself defines a BTI0. If we define: #define FLAG BIT0, is it better? Does i...
