I2C for PIC Microcontrollers
In this article, we will take a closer look at the I2C serial communication protocol. This is the second in a series of three articles covering serial communication; the others focus on USART and SPI. In this post we will explain what I2C is, how it functions, and how you ...
Using PWM in PIC16F877A
Digital signals (0 or 1) and analog signals (range of values) are both used in electronics. Analog inputs can be converted to digital through an ADC. To control analog devices with a microcontroller, DACs are used but they're costly and space-consuming. PWM (Pulse Width Modulation) is a cost-effective technique that ...
