lcd

问题 I have the following CodePen: Test LCD with CSS Variables, in which upon clicking labels with specific digits, results in the appropriate LCD segments to be "lit" based on algebraic equations I've determined to mimic a BCD to 7-Segment Display Decoder, in order to simulate an LCD display... I currently have the first segment's equation mentioned in the CSS. Clicking on a digit in the CSS should theoretically result in the appropriate four --input variables to be populated with a pulse (0 or 1

问题 Good morning guys. I bought a LCD embedded display with a resistive touch screen integrated. The TS is interfaceable via USB. I have connected it to a device running Android 4.0.3 and the touch is correctly recognized as externale HID. PROBLEM: the tapping (pressing) is not recognized as selection/confirmation...the only thing that happens, when I tap the screen, is to move the pointer(arrow) in corrispondance of the coordinated of my finger..like I moved a mouse HID without left left

问题 I wrote LCD interface program for Atmega328 (Though there are libraries available, I wanted to write from scratch). But have two problems. 1. Sometimes LCD does not display correctly. Only few strips are seen. I end up in resetting once or twice. 2. I am unable to display hexadecimal values usingdisplayOneByteHexValue(). However ASCII coversion was correct and I could see that in Atmel Simulator. Below is the code. I am using Atmel Studio 6.2 /* * EmbeddedProgram1.c * * Created: 16-05-2015 08

问题 I have a problem with an activation/deactivation system for Arduino. I can get the code to activate or deactivate once I upload a fresh copy of the code, but once I activate it after upload and try to deactivate the security system, it only takes in 2 numbers and then prompts me to Wrong password. #include "Keypad.h" #include "LiquidCrystal.h" #include "Password.h" LiquidCrystal lcd(0,1,10,11,12,13); char newPasswordString; //hold the new password char newPassword[4]; //character string of

问题 I want to write a function to print characters on an LCD in a similar way that printf/sprintf does using formatting strings. 回答1: You may use sprintf function to format the strings and print to LCD. char buffer[50]; int a = 10, b = 20, c; c = a + b; sprintf(buffer, "Sum of %d and %d is %d", a, b, c); Now the buffer will have the formatted strings 回答2: You could write a variadic function and pass the parameters on to vsnprintf() : #include <stdarg.h> #include <stdio.h> #include <stdlib.h> void

问题 Has anybody ported Chipsee 7 inch LCD on Linux kernel 3.14 or later ? Is there any patch available for the same ? If no patches any suggestion porting Chipsee LCD support from Linux kernel 3.8 to Linux kernel 3.14 ?

问题 I need some help to resolve a "section type conflict" in an arduino program I am writing. I have a short example code that produces the error: #include <glcd.h> #include "M2tk.h" #include "utility/m2ghglcd.h" #include "bitmaps/allBitmaps.h" // Definitions of Main Menu M2_LABEL(el_label_MainMenu,NULL,"Main Menu"); // Construct Main Menu List M2_LIST(list_main_menu) = {&el_label_MainMenu}; M2_VLIST(el_list_main_menu,NULL,list_main_menu); M2_ALIGN(el_main_menu, "W64H64", &el_list_main_menu);

问题 We have a character LCD (www.cloverlcd.com/pdf/S6A0069.pdf) that we got to work in 8 bit mode. However, now we are trying to get it to work in 4 bit mode but it doesn't seem to be displaying anything. I think the function set instruction isn't been written. Can somebody please check if I am approaching this the right way? I'll post my 8 bit code (which is working) and my 4 bit code (which I'm trying to get to work) //8 bit working COMPortC(0x3C); //function set Delay1KTCYx(10); COMPortC(0x0F)

问题 I am following this tutorial, but I am doing a very basic version where I just want to print something out. All the pins and hardware specification are followed as per that tutorial. Below is my app.js code: var five = require('johnny-five'); var board = new five.Board(); var lcd; board.on('ready', function() { lcd = new five.LCD({ // LCD pin name RS EN DB4 DB5 DB6 DB7 // Arduino pin # 12, 11, 5, 4, 3, 2 pins: [12, 11, 5, 4, 3, 2], rows: 2, cols: 16 }); lcd.clear().print("Hello NJ"); this

问题 I have a waveshare 3.5 inch touch LCD display and I m trying to get it working with the latest version of Raspbian A.K.A Raspbian Jessie. I followed futurice.com 's tutorial on getting it to work (tutorial is titled I'd like some LCD on my pi) and it worked on Raspbian Wheezy just fine. All I get now is a blank white screen. All help is greatly appreciated! (I must use the official Raspbian Jessie image without NOOBS from the Raspberry pi website.) I have a Raspberry Pi 2 Mobel B +. 回答1: From
