Project is to write a sketch for the arduino IDE to interface an ATMega328 with a DAC (MCP4822 12 Bit) and Phillips PCD8544 LCD (Nokia 5510 LCD) over SPI DAC Requirements Rotory Encoder will be used as an input to send data to DAC Pushbutton(1) will switch between the 2 Outputs Pushbutton(2) will Step Up output by 10% increments then when 100% is reached will step back down Pushbutton(3) will ramp from 0 - 100% in 30s then stop, button is pressed again will ramp back down Rotory encoder will override Pushbuttons 2+3 when rotated LCD Requirements To show which channel is selected on the dac Channel 1 will display Voltage Then underneath show a reading from one off the analog pins which will scale a reading from 0-2.048v to 0- 10v Chanell 2 will display Current Then underneath show a reading from one off the analog pins which will scale a reading from 0-5v to display 4-20ma Code shall be written in the most effective and efficient manner must include Code Notes

Hello, I have a long experience in Hardware and Software product development. I am also have done several Arduino projects (some of them on freelancer.com). I have an Arduino board and I can use it to compile and test some of the functions like voltage measurements etc before delivering. I have also included the price (and time to buy) of a PCD8544 that I can buy and test the software for delivery. Please let me know.. Thanks Vinod

I am not familiar with Atmel chips as I didnt like to use anyway. I am a microchip fan so all my 8 bit coding is limited to PIC micros. It seems some kind of power supply related design. Rotary needs velocity control so that when you rotate the encoder faster then it will increase the values faster. MCP4822 is a nice DAC which I use mostly when 12 bit is required. Its just a formal bid because I cant work with arduino even if its too simple to code. So in case if you have plan to use microchip PIC device then please do get in touch. I used such kind of setup in one of my power supply project which had USB connectivity and MCU was PIC18F4550 and true USB2.0 port. Thank you very much for your time. Regards.
