Hi,
I am about to create connection between an ADS8344 and a ATmega16, using the SPI interface. Is there someone that can give me any tip?? Should I have separate ground planes?? And if so, which of the pins on the A/D-converter should be connected to the analog GND (AGND) and which should be connected to just GND?? And the GND-pins on the mega16, they are all digital, arn't they?? For the AVR mega16 I'll use a chrystal on about
6MHz. The A/D-converter have 8 analog signals of about 1V on the input and the maintask for the AVR is just to convert the SPI-signal to UART-signal, whick will be send further. Will the mega16 need any decoupling capacitors?? In the datasheet of the ADC, there are some pictures of the basic operation, including the decpupling capacitances and so on, but I can't find anything about the mega16.As you can see, I am new in the area and I am geatful for any information I can get!
