Actullay I have got STK502 starter kit (extension for lcd avr ) . I don't have STK500 board . The kit has a atmega 169 microcontroller . Can I programm it with this kit .
plz send header file 16 x 2 monochrome lcd in atmega 16 (code vision avr)
Dear Forum, I need your suggestion and solution. I have problem with my semester project, I make data acquisition using avr atmega 8535 and Delphi 5. This data acquisition use for measure voltage (ADC 10 bits) and the result will be display at lcd Graphic and Delphi Chart. I use four channel ADC from atmega and I use (...)
Sorry I worked with C. Many sample codes available for lcd for avr in assembly.
The main goal was to increase the frequency range but maintaining the cheapest cost. Large and inexpensive color display has been used. Drzasiek wanted build a mobile device, so he was looking for small elements.
What is the response given by your modem for the command "AT+CMGR=1\r\n"? #include <avr/io.h> #include <lcd.h> #include <avr/interrupt.h> #include #include "uart.h" #include #define UART_BAUD_RATE 9600 /* 9600 baud */ #define xtalCpu 7372800 unsigned char CtrlZ=0x1A; unsigned char msg
It depends on what language you use. - avr assembler is quite simple and well structured so you can write your program with ease. Anyway I didn't use I2C/TWI interface before, but the datasheet is comprehensive so you need to read it carefully. - If you want to finish the project rapidly and with full features you can program it in C, using
i have made a small web server using wiznet NM7010A. i can syccessfully run the demo web server program given by wiznet. i can send data to my lcd and turn on and off some LED as per the web page. i want to control port0, PORT1 AND port3 using web server. when i try to expand the html code the web server dose not responds. i have individually te
I want to interface a USB based Keyboard to a 8051 microcontroller. Data from the Keyboard (thru the USB) must be sent to the microcontroller (whenever user presses keys) and will get displayed on lcd. Can anyone please let me know how to start with this?
I am new on this forum and say "Hello everyone!" I want to measure and read in real time the speed in mm/sec. I use a linear transducer (it work between 0-10 V dc.), atmega 8, lcd 16x4 and to compile i use Bascom-avr. I tried several times to write the code , but without results. Can you help me with code in (...)
Hi, I wana creat a up down scroll menu using atmega 128 on a Graphic lcd. Can some body help me and guide to some code or tutorial for it. Thanks to all!
Hello friendz!!!my project on DAS.M using avr for that.the output is displayed on Glcd320*240.I have a problem in interfacin that lcd with atmega16.Please guide me to interface glcd with atmega16.....please i need your help!!!!!
I have the same problem. But I am using the atmega16. The porta is connected to the lcd1602 dataport and it works fine. When I connect the dataport to PORTC, the lcd display nothing. I've already set PORTC = 0x00; DDRC = 0xff; but nothing change.... I hope someone can help us!!!! p.s. I am using the Codevision (...)
i want to program 2*16 lcd on assembly language for my project electronic voting machine. Controller used is avr at-mega16. there are 5 candidates and a total of 20 votes possible. every candidate is assigned a register and the value increments if the candidate gets a vote. i want to display the end values of these registers on lcd. at first (...)
I am using atmega32 to display something in a 16x2 lcd screen. The problem is, I have used PORT C for lcd connection and is not working. Later I erased the micro-controller and wrote a very basic program to alternatively make PORT C high and low with some delay (1 second) in between. Now, only 4 bits of PORT C is working as I expected. (...)
hi all,i need c programming using atmega 128 avr to display lcd,to display spwm,and analog to digital converter,who can help me please?.see you
Firstly, I havent worked on Glcd's yet so I dont really know how are they operated. Secondly, take things slow and step by step when you get stuck. I suggest you disconnect the lcd for now and place LED's at some port. Such that, the number you press gets output at that LED port. In this way you ll break down a much complicated problem in to a simp
If you ignore the lcd display part, which is for informational purposes only, you'll see, that the code is mainly reacting on the level changes of the DTMF outputs. The coding style isn't applying for a brilliancy prize, but understandable though. You need to get familiar with common methods of masking port bits and similar stuff.
Recently I bought a USB ISP for ATMEL avr serires controller. (somewhat Similar to picture attached). I attached the programmer with atmega128A chip with crystal & other basic components, the chip is being written & read, now I want to know for running the hardware which will include a 16x2 lcd I need to detach the ISP & then provide the (...)
Guys, I want some opinions from you guys picking right Atmel/atmega controller for my project purpose which following specifications: 1. UART connections 2. lcd display 3. Keypad 4x4 4. SD card write/read data Regards Linspire
Always use an endless loop at the end of main, you shouldn't allow execution to exit the main. #include<avr/io.h> #include #include<avr/eeprom.h> #include #include #include"lcd.h" #define read_eeprom_byte(address) eeprom_read_byte ((const uint8_t*)address) #define write_eeprom_byte(address,va
Are you making calculator with lcd and atmega16 ?
I have seen many on the internet using some mp3 decoder ICs. Can the decoding be done on software (16Mhz atmega) aside with controlling a graphical lcd and keypad or pushbuttons (is the processing speed sufficient)? I would tend to agree with sky_123 that the atmega would most likely not provide the required MIPS or
just wanna share this. i got it working but the problem is that its not *that* precise, but its okay for a start, i guess.. the code #define F_CPU 8000000UL #include <avr/interrupt.h> #define USART_BAUDRATE 9600 #define BAUD_PRESCALE (((F_CPU / (USART_BAUDRATE * 16UL))) - 1) #include #include<avr/io.h> #include

i have interface ad7796 chip to atmega 16 using SPI. The input is taken from two strain gauges and connected to the ad7796 chip and the output is viewing through lcd. But i am getting zero value as output. i am attaching the code. I need help. The code is given below. #include <avr/io.h> (...)
Couple of simple observations -- 1) your ADC isr is way too long in terms of execution time. You have float operations as well as lcd outputs going on inside which take a long time. 2) the line -- tenBitValue = ADCH<<2 | theLow>>6; is incorrect. It should be :: tenBitValue = ADCH<<2 | theLow ;

Hi, Is there any way to connect multiple SHT11/SHT7x to a single Mega8 or Mega32?? They are using the SCLK and Data pin. So for 3 sensors, do i need three datapins, or one only?? Also i need the same SCLK and DATA pins for lcd display. So any ideas????
