difficult to say without having more details provided. VGA is an analog IF with RGB +Hsync +Vsync. lcd panels work on a digital base with TCON ICs. They have digital IF, eg RGB888, RSDS, oLDI etc. So somewhere in betrween there has to be a adc converter unit involved, which does the sampling & convertion (...)
the lcd screen was showing texts and keypad touch successfully when adding adc_read(0) ntg is shown the lcd Understand a question posed like that is a real puzzle; anyway, concerning to the code in question, I would recommend review the adc_Init() command to know exactly what it is supposed to do. For instance, we d
Hi For my new project i have to display signed analog values on lcd. ie both positive and negative values i have to display on lcd. The adc i am using is AD7714 and the MCU is ATmega8. I configured the adc inputs in the differential input form and i set a constant voltage(+1V) at one of the adc inputs as (...)
Hi For my data acquisition project i need to interface the external adc AD7714 with my micro controller ATMEGA8A which is running in 16MHz. The adc is running in 2.4576MHz. These two are interfaced by SPI protocol. i configured all the registers and when i am trying to read the data from the adc and displays in (...)
Hi, I am going to use CS5460 with AT89S52 . I have successfully able to read/write from/to CS5460 adc. Read some default register and shown result on lcd. Means my SPI routine are working fine. OK .. I have to measure 220V 15A 50HZ . CS5460 has large number of registers. I am following "AN220 from Microchip " ( www.t-es-
I am having trouble displaying the values of a changing register on my lcd. I tried using sprintf() to show the values of my ADRESH and ADRESL but this showed up to be higher than expected. This is my code for accomplishing that. This is the program I have up to now. The variable value from adc is shown on the lcd however there is a problem (...)
- - - Updated - - - this is my project: clock of adc is 1MHZ and my controller use external osc with 8Mhz frequency.i want to write one code like it . i wanted to chek it with some signal in input. when u give it a signal with constant frequency it code
You need to use a conversion function like sprintf(...) to convert the float value to an ascii characterstring in a buffer. You can then write the contents of the buffer to the lcd.
i am working on xmega128a1 with an external adc that has more than 1mhz speed. i want to read from adc and show data on lcd. but during to show it lose adc data. also i use dma and save data and then show them.but for save data with this speed need to big memory and idont want to use (...)
Now both variable are declared as float and I apply your code the answer is strange am attaching the image that what i get after applying the code. my expactation was 2.500 but the lcd displayed 159.843
I wrote a code for reading adc value from POT and displaying it in lcd but proteus showing it as Simulation not running in real time due to excessive cpu load code is // lcd module connections sbit lcd_RS at RB4_bit; sbit lcd_EN at RB5_bit; sbit lcd_D4 at RB0_bit; sbit (...)
coding for sending the data from adc to the lcd for displaying. m using 2 sensors interfaced with the adc like ldr and lm35 and want to send the data to lcd :roll: Hi, It's better if you can show us some of the code that you may have done. Thanks
can anybody plzz give the code and schematic diagram for following. i want to do display lcd using adc pins in atmega16. so i m in thought to do it for temperature display using LM35. so plzzzzz send me the code and schematic diagram and i want to execute it in proteus and then do hardware.......plz do help me........awaiting for reply.......
Now you have to make it work with interruptions only... look for examples of adc interrupts on the web, each time the adc completes, you have to do a quick calculation for each Form1 and Form2 values... then make a timer interrupt (maybe TMR0) and every time it interrupts, you check Form1 if it's higher than 9.8 and fix your duty1 according (...)
hello everyone, consider the following condition. we are going to share a adc pin for measuring analog signal as well using it as digital output to lcd data pin. for adc i/p to mc: will the lcd data pin act as load or will it be in high impedance state? for lcd i/p from mc: will the analog input (...)
Can any one help me on this. I am working on voltmeter using the adc of pic6f877a with lcd , my code works perfect on proteus but when i implement it, it won't respond fine. At times it display, at times it don't. Pls i need help.
I think a Waveshare AD Keypad will be better. It needs one adc pin to interface 4X4 keypad for RTC setting and lcd navigation. A MCP9808 will all do.
I am facing too much problem while working with DSPIC30F4013. When i am sensing a dc voltage of 15mV from a circuit adc value gives zero. At 23 mV dc adc value only 2 or 3. I am giving my program here. please give me a solution. // lcd module connections sbit lcd_RS at LATD0_bit; sbit (...)
Hi all, I get my first exact work for my PSoC Project. I Need help for this. I want value of adc_DelSig with Resolution bits 16 & input range Vssa to 1.024V (0.0 to Vref). This value i want to Display on lcd. I write some code for this from the reference of Example code "Ex2_adc_to_lcd". But it Display (...)
which microcontroller are u using? The selectable 12 position switch will have perticular voltage output for each selection. This voltage can be given to adc and corresponding msg can be read from ROM and sent to lcd_print function. is lcd alphanumeric or graphic? If its alphanumeric there are plenty of example codes online. Can u share the (...)
