For the first example, suppose you need to monitor a DC bus voltage using a microcontroller’s ADC input. During normal operation, the bus voltage is fixed at 24 VDC. For this example, the ADC will ...
The solution was this circuit from Bob Pease’s excellent Troubleshooting Analog Circuits. This gem reduces the rise and fall times of the 4N25 I had on-hand by a factor of at least 25, from a ...
The baseline PIC microcontroller, which includes the PIC10F, PIC12C508/509/510, or PIC16F505/506 series, uses its internal timer, Timer 0, to count the number of instruction cycles that execute in one ...
