PIC: Serial Communition in PIC Microcontroller- 1

Post Thumbnail of PIC: Serial Communition in PIC Microcontroller- 1

An introductory post on how to use serial communication in PIC Micrcontrollers to send data to PC. What comes first in your mind when you listen serial communication ? Yes, how to send data in series. All this time you have been working single bits, turning on and off. Well serial communication is nothing more than on and off, but the only difference is that it has certain rules and timings which make it the reliable and accurate communication protocol among all.

Circuit: Transistor based 3.3V-5V Level Translator

Post Thumbnail of Circuit: Transistor based 3.3V-5V Level Translator

Nowadays most of the devices are running on 3.3 volts, and likewise their communication levels also work on 3.3 volts. For example XBee runs on 3.3 volts and to interface it with microcontrollers running on 5V, one needs to translated voltages levels so that they both communicate. This post gives a schematic of transistor based level translation with Proetus simulation. Continue reading
