Interface the LCD with 8051 microcontroller at89s52. But whenever I power up the microcontroller, LCD is lit but only black boxes are showing. I have tried many different codes and many things, but display is same. onle black boxes. But i have simulated this circuit in proteus. here, that LCD is giving correct output. Plz help in determining the problem.
Click here to download the full size of the above Circuit.
Here are the attached code and circuit diagram. Here is the C Code. Thanx. Now the c code is compiled successfully. But I cant run this program in Proteus simulator. It dows not give any output. I can not find pin 6 of that LCD module. So i have to change circuit a bit. Plz modify it if necessary. . . I have used lm032l and this time result is positive. though a small error much like warning is displayed in proteus. I am attaching modified. /files with code. Sir, as today our burner didnt work, so we cant test that circuit. will test again tomorrow. mean while I need help also for completing our main project : digital room thermometer as our mentor are out of touch of these microcontroller and these things and it is too much to handle of our own. So, plz help. I am attaching circuit diagram here. At first, tell me the important things to test in order to start that project finally. We have tested 2) tested ADC 0808 in free running mode and it is giving correct output. We kept reference voltage 1. 28 volt so that the step size is in accordance with lm35 step size. next thing to test is ADC with microcontroller. coz You will test your LCD so there will be a display to print your test results. You guys are going on the right track give us some ideas for how to test adc with microcontroller what things we have to include in the c code then i can write it now and post here to verify. will u plz rep. sooner we have a deadline...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
