Hey,I would like to implement a digital voltmeter with PIC16F877A and an 16*2 lcdbut the conversion is not succeeding,the voltmeter has to measure 0-30VDC but I am not getting good values. Could you please help see the codes here below:#include <16f877A.h> //Header declaration for pic used #DEVICE ADC=10 //definition of ADC bits for conv
I'm trying to interface a 16*2 lcd display and 4*4 keypad with lpc 1343 board. I have successfully finished interfacing the lcd. but can't find the keypad.h header file to interface the keypad. I'm using lpcxpresso v7 IDE. i'm comfortable using keil uvision5 too. help with the keypad interfacing code would be most appreciated.
This is a simple example of using the Keypad Library. It supports keypads with 1..4 rows and 1..4 columns. The code being returned by Keypad_Key_Click() function is in range from 1..16. In this example, the code returned is transformed into ASCII codes and displayed on lcd. In addition, a small single-byte counter displays in the second
I bought a 16x2 display off ebay six years ago and I am finally getting around to building something with it. As far as I can tell, its a HD44780U display and it appears to have ROM code A00 (reduced character set). When I first got the display, I tested it quickly an
probably the simplest way is to keep a copy of the strings you have written to the lcd (as char arrays with 16 characters) and as keys are pressed update the string and then write the 16 characters to the lcd otherwise note the column you have last written to on the lcd and when you get a backspace move one column back and write space (...)
hi , i am using the microblaze to calculate some thing and after that i want to show it on the lcd i have on my board . i ddidnt know exactly how to do it , so i searched and now i want to use this code to run the lcd for now : #include #include #include XGpio e,rs,rw,lcd_data; char reverse(char data) {
Hi guys I am trying to connect a 16x2 3.3V lcd with PIC32MX250F128D. Spent lot of time with no positive result. Please help me. The following code will explain my connections. // lcd module connections sbit lcd_RS at LATA10_bit; sbit lcd_EN at LATA7_bit; // sbit lcd_D4 at LATC6_bit; sbit (...)
I agree with the analog method. I got this 16 X 2 lcd Keypad Shield for Arduino V2. It does a nice job with 5 buttons on one analog input (A0). Any combination of the 5 buttons lead to 32 different key values.
Prolonged exposure to direct sunlight can certainly permanently degraded several components of the lcd, including the polarizing filter and clouding of some layers. lcds are also very susceptible to changes in temperature, especially to prolonged exposure to high temperatures found in direct sunlight. Such prolonged exposures to high temperat

I've got a test project for a PIC32MZ chip (PIC32MZ2048ECH100, microchip's PIM) that compiles just fine. The code works up to a certain point. My code is just meant to test an lcd module by filling the screen with a 16-bit color variable and incrementing the value of this variable (by 0xFF) on each pass of the main loop so what I get is a scre
If I remember correctly, Bharat Electronics (BE) makes them, even jumbo size single seven segment lcd plates. may not be display modules. Coming to things like 16*2 20*4 etc modules, Hyderabad based LAMPEX used to make them. perhaps their registered office might have shifted to Mumbai. ps: here is their link
I just solved my display problem( i wasnt getting anything on display ) and now i seems to have ended with another problem. I have set the contrast pin as specified that is connected it to 10k Pot. but you know whats happening is, the contrast looks really good when i turn it on, but after about 10 seconds it starts fading and then it reac
Your circuit is fine. I will check the code and update. I think this is causing the problem. I guess it should loop from i = 0 to i < 16. The lcdbuf1 and lcdbuf2 doesn't contain anything and hence 1st coloum of lcd will be always blank but the 16th column will be filled. If you have Proteus file then Zip and post it here. [syntax

Hello, i'm beginner in Microcontroller and i have the explorer16 (pic24fga010) board ans i would like to connect LM35 to my board and display the value of tempertaure in the lcd. can someone help me please ? thanks in advance
hello, if you are using a 16*2 jhd162a lcd then you canuse one more method that send 0x80 as instruction to the lcd that is the start address of the first line and after that you can send 40 bytes to the lcd as data and the second line starting address is 0xc0...
Hi, On your lcd it shows a value of more than 150.000. How can this be? The max for a 16 bit value is 65.535. Or are you working with more than 16 bits resolution? Klaus

worth checking for a poor connection (press on the display and try a soldering iron on the connections) I have had lcds fail on Microchip's explorer 16 development boards - changing the display usually fixed the problem
How long are those delays? You seem to be using typical values in mS but the delay is actually just a decrementing loop, with a 16MHz clock each pass of the loop will only be microseconds. Also check the initial start-up delay (line 23), on some lcds it can be as much as 100mS before they accept commands. Brian.

Are you using standard ISP/SPI programming or high voltage programming (HVP)? Typically, ISP/SPI programming will not damage an lcd/Glcd. Can you post a schematic of your design? Have you attempted to program to AVR with know working firmware, to verify the JHD162A is indeed damaged. Double check the connections and any solder joints. If it is
