Greetings,
Does this circuit work well? Application : to control speed of ceiling Fan or to control brightness of a Light bulb.
Components : MOC3021 (optocoupler), BTA12 600 (TRIAC)
Thank you !
See, I already told you in my first post to use Licensed version of keil. The problem was with your unlicensed keil, it supports program code limit of 2KB only.
Good Luck :)
Greetings,
Unlicensed version of keil only allows you to program upto 2kB of code.. So buy licensed version of keil or use free IDE.
I think it should be your not you're (you are) :p
Good Luck
Greetings,
Do you want touch screen only or display+touchscreen??.. For the latter follow the link

Good Luck :)
Check all your microcontroller connections
1. check 5v and ground connections
2. check your crystal oscillator and ground it properly
3. check whether 31st pin of your microcontroller is connected to vcc 5V or not
4. Select right com port in flash magic
5. DB9 connector 5th pin must be grounded...
Greetings,
First find out which com port your usb to serial wire is using, go to the following link you will find step by step info on how to program p89v51.
Important step: In flash magic, Goto options -> advance options -> in hardware config tab uncheck use dtr to control rst
Follow this...
Greetings,
Do not worry, what you need is called Voltage regulated supply(5 volt).
Here is a Post link : https://www.edaboard.com/threads/221061/
Please read the whole thread as it might help you understand few more things. Comment #8 will give you correct circuit image.
You can also use 12v, 1A...
Greetings,
Sorry thannara for late reply but I am so busy with my project, here is a working 4 bit program but the read, write enable pins are at different ports. So you have to edit it according to your needs.
#include<reg52.h>
#define ldata P1 //16x2 lcd data pins to port p1
