News 8051 Projects

Well this is one of the most interesting and long awaited project uploaded on any microcontroller website. Its an Inverter/UPS with inbuilt charging system based on 8051 (AT89C2051) with a rating of 3000VA. As you all know an inverter converts DC voltage to AC, This project uses 24V DC battery and convert it to 220v 50Hz AC. Here are some pictures of constructed hardware.
The inverter system is divided into six sections:
- Sensors and Indicators
- Automatic changeover
8051 controller plays its major role in "Sensors and Indicators" section. 8051 is used to monitor the voltages and indicate status through LEDs. You can also find UPS test design for Proteus VSM simulator, to stimulate the design in case of any doubt. It is the same controller circuit as given in pdf. At89c2051 uses an active low to perform its operation from lm393 voltage comparator that's why a push button is connected to ground to test the circuit.
You can find pictures, code and small documenation that explains the working and block diagram of this project. Incase you have any doubts, feel free to post on our forum at www.8051projects.net/forum.html
I would link to thank Victor (ugoo5000) for sharing his great project again with us. Also I want to apologize for delay in uploading this project I should have done it earlier. Thanks Victor for great contribution to this webiste.

hello! newbie here. i am kind of a guy who hates using ready - made existing libraries, so this helped a lot as i was trying to control and write to a character lcd display. however, i can't figure out how to set the cursor position. for example, i want to set it to the 5th column in the first row, so position 5. so according to the table, i am sending 10000101 on the 8 data lines of the lcd (register select pulled low). the cursor does not move there however. and i cant move the cursor left or right too. is it something wrong that i am doing? thank you.
