Common request here in this forum have to do with ADC. In addition to complex devices to be addressed by parallel or serial (SPI or I2C) protocols, there is the low cost variation of PWM. Voltage controlled oscillators (VCO) are a special kind of PWM generators, easy to read and terribly low cost: Some CMOS ICs have a VERY…
