Hello! Greetings from Brazil! Can you recommend an ATMEGA with 2 UARTS? The reason that we will use UART is simple, its more reliable than software serial. I don't know if everybody agree with that. Thanks! Cleber ------------------------------------

I have an Atmega 128 and read the manual. On page 180 the information given does not include whether the transmission signal sent out of the TXD pin (3) is inverted or non_inverted. I know the default transmission settings are 8N1 9600 baud, but I need to verify if it is inverted or non_inverted. Also, If I use the chip for only transmission, do I need to ground the receive RXD pin (2) or do...

I am trying to develop DAC circuitry for Atmega 16 since Atmega16 doesn't have in-built feature of DAC. The circuitry design will be 4X DAC design using AD7528 DAC Chips To my understanding, PortC0-1 (SDA/SCL) of Atmega 16 will be used to drive the DAC circuit which will output variable voltage 0DVc - 10DVc at fix current 25mA using Op Amp. I am not trying to ask anyone to do homework ...

Hello all, I have a Robostix and when I go to their Wiki page it has the all of the C code and headers except the 'lcd.h' header file. Does anybody know where I can get this file or at least a working package. I'm trying to learn how interface sensors to this thing and I can't tell if I'm getting good data. I also have an Olimex ATMega128 board that I think works. I just need to p...

I'm on a school project and the aim is to aquire data, so i'm supose to connect a MCU to the CPU so i'm using a RS232, MAX 232 and a cport lib i found however no matter how simple the code is on the Atmega8535 the computer will not recieve and i dont no why, i even used a serial loop back test on the computer and it worked and all mu atmel is doing is "U

Hi all, my question is related to the use of an external RAM (32kx8) controlled by an ATMega162. Current situation: My old application with an at90s8515 works fine with an external RAM. Now I switched to the new 162er. I shifted all cseg commands as well as the SRAM locations and the stack-pointer in my existing code. Everything works fi

hello guys I am using two atmega 16 avr boards and I want to intercommunicate between these two boards with the help of a transceiver. So can any body tell me any cheap transceiver which can be easily interfaced with the avr microcontroller and is easily available too. Thank you ------------------------------------

I am struggling (newbie) with code that will do the following, say on an ATmega running at 8MHz: 1. PWM for six motors (not servos) running in one direction. 6-8 bit duty cycle resolution is fine. 2. Sample a few sensors. 3. Receive motor speed commands via serial. 4. Send sensor readings via serial. 5. Kill all motors if no commands a

Hi guys, Finally I have written up a code to generate PWM, and by changing the output compare I am able to vary the brightness of my LED. I also went ahead to use interrupts so that everytime there is a match, the Interrupt Service routine could increment the output compare value, so that the LED can increase in brightness gradually. I had written t

Hi all. I am working with ATMEGA169 microcontroller. I am using a battery to provide supply to the board.I am uisng ISL6292 battery charger. A TEMP pin of the charger monitors the battery temperature to ensure a safe charging temperature range. This TEMP pin is connected to ATMEGA. Some voltage is appearing on this pin from this voltage how to calculate the temperature. ---------------------...
