Hi all, I want to build a dual time zone clock with PIC or avr. Need to see Brazil and Italy time in the same display at the same time, may be a two or four line(four is better to see) lcd. If possible using a precise external time base generator like DS1307 or similar ones. Regards, Fernando call sign PU2PLL
Hi, I am new in C programming language, but experienced in asm for 8051 and avr ... I'm trying to drive a segment lcd in Stm32L476 discovery board, i could do it well but i see a problem when using bitmap table, i use a table to assign true active segments for each number. i used a 3D array for this purpose: const uint32_t Table[

hello,i wanted to interface 2 atmega8 ic through SPI and i wrote theise code as Master and Slave but when i execute the code in circuit in proteus app it wrote "Testing" in lcd but then nothing and the transfer cant complete wnd the code freezing in the code line: while(! (SPSR &(1<
I am trying to read ADC in atmeg 32 .Displaying the data to lcd to a vlot /ammeter project . my problem whenever simulate it on proteus it will hangup on the checking of ADSC conversion /* * vmam.c * * Created: 14-Oct-15 6:44:15 PM * Author: Krishna */ #define F_CPU 16000000UL #include <avr/io.h> #include #include"l
hello all i wanna to connect sht11 with long cable to atmega32 when the length of cable is less than 30 cm the micro show the data on lcd and the data is correct when i try to connect sensor with a cable =1 meter to micro didnt show anythings on lcd!!! how can i increace the distance bitween sensor and micro? sht11 worked with i2c protocol
My lcd 4bit code is not working in hardware. Why ? I am using IAR EW avr 6.60.1 licensed Compiler, ATMega1284 @ 8 MHz external clock and mikroElektronika's Easyavr v7 development board. I am attaching my IAR avr project. lcd code is correct because I use that code in other compilers. I think the problem is (...)
hello to all ... I simulate a graphic lcd 64*128 in proteus and program the micro with codevision avr and atmega64 but just show some point! did you know whats the wrong? tnx from your good site the schematic and code is here 117920 #include #include lcd.h> #include void main(void)
Multiple I2C lcd with avr and mikroC PRO avr. I didn't post in my previous Multiple lcds thread because this is for avr. This is a Multiple I2C lcd library. You can have 8 I2C lcds on one I2C bus. I have used I2C lcds and modules from Banggood.
This is Multiple I2C lcd code. It is written using CCS C Compiler version 5.044. This si tested in Proteus and also EasyPIC v7 development board with 2 x 20x4 lcds. lcds should be HD44780 or compatible. I have used I2C lcds and I2C lcd modules from Banggood. I will soon post mikroC PRO PIC and (...)
STC8051+avr+atmega Professional Kit is a high-performance development board with rich board resources. The board has many peripherals such as dot matrix LED, color dot matrix lcd, SD slot, PS2 port, stepper motor driver, DC Motor, infrared sensor and temperature sensor. It reflects fully STC Microcontroller performance. Please see the details in t
hi in a project I'm working on 7 inch TFT lcd and ATXmega128A1, we need save font and icons on flash memory of avr, now the memory is full and need more space so we decide use SD card for save fonts and icons on it in FAT format, but I don't know how can I use Glcd function by external memory. for example we use (...)
3 bit = 2^3 = 8 values. Do you mean 3 digit ? like 0 to 999 ? You didn't answer whether you are using 7 Segment display or lcd. If 7 Segment display (SSD) then is it Common Cathode (CC) or Common Anode (CA) ? I will write code if you answer my questions.
My project is I2C lcd with ATMEGA1284. Project tested in Proteus and also mikroElektronika Easyavr v7 dev board. Code is written in mikroC PRO avr compiler and uses TWI library. mikroC PRO avr files and Proteus file are attached.
i write a code for jhd-16 * 2 lcd it is working on protious but not on hardware ? i give about 50 ms delay after each command even it is not working with such a big delay
Hello. I program Microchip and Freescale MCUs only, I tried to start with avr but where I live programmers and good MCUs are expensive. I made a C function to drive exactly the same IC, I used it to control a 16x2 lcd when I ran out of pins. Make sure it can supply every LED row current. By the way, you must add resistors to rows OR columns. I t
Thankx Susan for your reply but now simulation Works properly but not working in hardware i am sending 1-5 digits with the delay of 1000ms but when i check the receivd values on lcd but lcd countinously shows 255 and some time other garbeg values and i am not getting where is problem:roll:
I want to delete single character while entering if it entered wrong in lcd, suggest me in this code how to do it. void wrcommand(unsigned char command) { cbi(PORTD,PD3); PORTC=command; sbi(PORTD,PD4); _delay_ms(10); cbi(PORTD,PD4); } void wrdata(unsigned char data) { sbi(PORTD,PD3); PORTC=data; sbi(PORTD,PD4);
Hi, i am trying to interface 16x2 lcd with avr microcontroller. i am new to c language and avr as well. although i am familiar with PIC and C++.
