I try to use Xlcd library with default pin setup, It compiled successfuly. But when I simulate it gives this error. Attempted to read after writing a single nibble When I only use OpenXlcd command, It again gives same arror. OpenXlcd(FOUR_BIT & LINES_5X7); Here is my code, #defin
Hi I was working on my old lcd TV ccfl power supply. Incidentally the TV was repaired by a non authorized TV repaier technician and now was problem associted with CCFL gate driver, I traced the circuit diagram for isolated gate driver for the MOSFET to be similar to the image attached. however I am unable to read the components value from the
Please let know any website for Non Chinese lcd for Microcontrollers i.e Arduino, PIC, STM32 etc.
Hello, i need to design a driver to the lcd described on the following image. 156281 I'm using a frequency generator with a 5Vpp TTL signal to activate one segment or word of the lcd and commuting the corresponding COMM's but i have many interference, so... - I don't know if i'm using this correctly. - How i can

Hi i have a problem i hope you could help me. :) im interfacing a 4x4 keypad with lcd display using pic16f877a my pic16f877a pic have a infinite loop while waiting for an input causing my i/o port's output voltage to be only 0.7V can u tell me how to solve the output voltage problem, its at PORTD PS: keypad_data returns 00H when what_button
Hey all, I want to build a power bank that's compatible with Qualcomm Quick Charge 3.0. There are many options available in the market but I want to do it myself so I could learn something. The power bank should have two USB A ports to charge the devices connected to it and one USB B(Micro USB) port to charge itself. What would be the majo
I have a tdk lamda power supply CUT35-522, which is 230V input, 5V,+/-12V output. I am using +12V output to power my arduino board with lcd. It works fine. The power supply claimed immunity to surge and EFT. To my surprise, when the supply was subjected to 2kV surge, residual voltage of +/-25V appeared at +12V output. This lead to resetting of ar
hellow guys i have a JHD-TFT1.8-16A lcd with st7735 driver in it. i want to run emwin on this lcd using a lpc1788 board. my board has a 32mb external ram and i am sure the ram config is ok. i write the below code to run emwin. but nothing happend when i use gui_setbackcolor function. please if some one knows whats wrong help me. i know this l
hellow guys i have a JHD-TFT1.8 inch lcd with st7735 driver in it. and also i have a stm32f103ve microcntroller. i want to run emwin on my lcd and i dont want use external ram. i use keil and range of internal ram in keil is started at 0x20000000 and the size of ram is 0x10000. first of all i wanna know is is possible to run emwin without extern

Hi, I am trying to control an lcd using a shift register. I am using the very successful arduino LiquidCrystal library which is tried and tested but am trying to modify the only function which differs. Instead of writing bytes directly to pins (like in the original function below) I am trying to output using a shift register (also as below). Its go
hello freinds . can you lead me to a way to try to convert transfer a hex file to nextion lcd . i can see many have done it but i coul not find a way to figure it out ,any ints tips thanks . the hex is public for a transmittar fm that work with push buttom i need to transfer it to touch screen .i see someone has done it before i have only a pict
Hello all my post readers, I am very new to FPGA, a weak ago started playing with a spartan 6. (Papilio pro). Now connected a 320x240 lcd to it and planning to do something with that as a hello world. I have a decent experience on electronics hardware, digital circuits and embedded firmware development. But first time with FPGA. Learning VHDL no
Hi Friends, I am designing a PCB board which consists of controller, Motor driver and lcd panel. Here the lcd panel input is feeding from the PCB board using FFC connector. Now i am thinking to modify the way of connection. Instead of FFC connector, I would like to integrate my lcd panel with PCB board using BURG STRIP through hole (...)
hi dear, i am new to pic and ccs compiler. i write a code for lcd interfacing and simulating on the proteus. lcd showes nothing. guide me please what and where is the error? the code is as following; #include "C:\Program Files\PICC\lcd1.h" #define lcd_RS_PIN PIN_C0 #define lcd_RW_PIN PIN_C1 #define (...)
