what is the difference between parallel mode or serial mode in lcd ST7565R??? Then what is the purpose for serial mode??
I am quite sure the lcd you use will adopt standard 3-wire spi and 1 select or enable, in the event this lcd shares the same spi bus with other spi devices. 4-line spi Clock that used in lcd, are this 4-line spi Clock is 4-wire spi?? can (...)
Hi, Has anyone tried to interface to the Nokia 6100 lcd (Epson S1D15G00 Controller), using a MicroBlaze microcontroller via spi ? I'm using a Spartan 3E fpga (60MHz). Can anyone give me any pointers on how to communicate with the controller over spi. What are the steps involved ? how slow/fast was the communication (...)
I have many example on PIC16F877A. It's is C Code using Hi-Tech compiler. I use Hi-Tech because it's already integrate with the MPLab software. My Lesson. The sample include LED, 7 segment, switch, keypad, lcd, comparator, ADC, PWM, Timer, Interrupt, EEPROM, UART, spi, I2C, RFID reader, GSM (AT Command)
Quite nice. How fast is spi bus in this project. Image loading is visible. Can it be improved? Will you share the source code? Is it just an evaluation board or a part of some bigger project? PCF8833 will not respond at higher spi rates. I am using software spi. its a home made PCB. I made that to familiarize USB h
Hi Sharath411, Kindly check this up... spi Graphic lcd Library (mP PRO for 8051) - Support Center -- this is by Mikroelectronica, provides builtin routines for graphic lcds and more tools for interfacing them.
it is probably simpler to use an lcd with serial interface, e.g. spi, I2C, etc. if you do an internet search on "lcd spi"
Hello, I am interfacing 4*4 keypad and lcd with AT89S52. I need help in C programming. I want to store the key pressed as Float value. eg. keypad 1 2 3 <-(Backspace) 4 5 6 ->(Enter) 7 8 9 .(point) * 0 # I want to take 1.2 as input from keypad, display it on lcd and when I press ->, it sh
lcds with HD44780 controllers are nice, but you can also reuse lcds from old mobile phones. The best place to start is Nokia 3310 lcd which you connect to your micro with only 3-4 wires I think (spi or IIC is there). The only issue is that you have to run your MCU with 3.3V or use voltage dividers with resistors. (...)
hello everyone! i am using P24F16KA102 i have interface lcd with it now i want to run digital trim pot AD8400 through it i can use spi for this but i dont know how to configure spi in this case. this is the code through which i have interfaced AD8400 with P24FJ16GA002 void main() { AD1PCFG = 0xFFFF; TRISB = (...)
hi friends i am new to this embedded world. for my project i am going to use the following applications 1) eeprom interfacing 2)inbuilt RTC 3) 5 analog sensors 4)2 i2c,2 spi(totally 4 communication protocol) 5)lcd interfacing(may be graphical or touch screen) 6)one RS232 interfacing please suggest me i have to star
Hi, There are a few lcds with spi interface, but these are expensive. For simple cheap solution, you'll have to have a master transferring data over spi to a slave which will then drive the lcd in parallel mode, ie in a regular lcd displaying method. Hope this helps. Tahmid.

MY lcd DRIVE IC IS ST7920: AND HERE ST7920'S DATASHEET MY CODE AS BELOW: DISPLAY NOTHING ON lcd #include #include<spi.h> _FWDT(FWDTEN_OFF)//7.37MHZ //lcd2232F Serial interface(ST7920) #define uint unsigned int #define uchar unsigned char void delay_100us(uint
I am glad it works, This lcd that you mentioned uses spi, if you search for it you will get many examples. some other graphic lcd's also use it. the best advise is to check the datasheet for this lcd
I need detailed explanation about functions of each pins and command set of 128X64 spi lcd. read the datasheet then. i need VL1001 datasheet tons of it here:
Hello, I have had DOGXL160 graphic display from Electronic Assembly with spi port. I unable to run internal charge pump. Vlcd is still 0V. I was trying all modes extept I2C but without any success. Is here somebody experienced who can hepl me, please? On the same spi I have connected a serial data flash which works well I have (...)
Hello, I need to add a spi eeprom to a board that has a lcd with no other free pins. The lcd is in 4bit mode. I am thinking about some glue logic in RS/EN/RW/D7, D7 being the real eeprom CS, but only allowed to go low for certain RS/EN/RW. D6,D5,D4 are SDO/SDI/CLK. What do you think? Thank you.
You can connect with LED, lcd or some o/p devices with some internal protocols like I2C & spi communication. Regards Chanchal
Hi, Many of the modern glcds use single controllers have a serial / spi interface so its usually very simple to physically connect to a micro. The problems for the diy user is that most run on 3v to 3v3 so an interface may be needed, and that they are on either very small pins 0.05" / 1.27mm spacing, that require very fine pcb tracks and so
