I love watching and playing cricket and football (soccer), and listening to music. I post to help solve electronics-related problems of engineers and engineering students from all over the world. I am a member of the forum where I am an "Advanced Member Level 5" (the highest level attainable) and also the forum, where I am a "Senior Member". I have completed my Bachelor's degree from Cornell University (Class of 2017) in Ithaca, New York, USA, majoring in Electrical and Computer Engineering (ECE). I've used PIC and AVR microcontrollers - PIC 10F, 12F, 16F, 18F, 24F, dsPIC 30F, 33F, PIC32, ATmega and ATtiny, integrating them with various SMPS and power electronics circuits. I learnt and worked mostly on SMPS, power electronics, microcontrollers and integration of microcontrollers with SMPS and power electronics. This 320 volts dc is fed into H-Bridge which converts it into AC supply of 220 volts by using SPWM technique. It includes dc to dc convert which converts 12 volts dc into 320 volts dc.

I am Syed Tahmid Mahbub, from Dhaka, Bangladesh, born on August 1, 1994.Įlectronics is my passion and from class V, I have been learning electronics. PIC based pure sine wave inverter complete design It is a complete design of single phase sine wave inverter. A red LED illuminates to confirm that a button has been pressed. To minimize leakage current through the input capacitor, I decided not to use an electrolytic capacitor. Instead, the remote relies on releasing the button and pressing it again. When a button is held down, the NEC command repeat sequence is not sent.
CREATING A SINE WAVE IN MPLAB XC8 SOFTWARE
Debouncing is achieved using simple software delays.

The interrupt wakes up the microcontroller when a button is pressed. After the IR command is sent, the microcontroller goes to sleep. So, in order to detect when a button is pressed, an interrupt is used. In order to power the remote off 2xAA batteries, it is necessary to use sleep mode - otherwise the battery will be drained extremely quickly. In order to connect all the keys, I connected them in matrix keypad form. I then proceeded to write an IR transmitter using the PIC16F684 (using the MPLAB X IDE and XC8 compiler), following the timing information from the extended NEC protocol. This left me with the following keys and commands: You can find this part of the project here: I decided to exclude some of the keys that were never used (eg play, pause, stop, fast forward, rewind). Using this, I found all the required commands for the different keys of the remote. I then proceeded to make a simple decoder with a PIC16F877A since I had a development board with an IR sensor mounted on it. 4: Extended NEC IR protocol pulse trainįrom the waveform, I found that the address was 0xBD02.
