ATMEGA32 SPI

Other Hardware 3rd Party Boards

Hello friends,

I am doing a project here i am reading a number of analog voltages.so i planned to use MCP 3208 to for ADC.but the problem is i am using and Ethernet module with the same micro controller atmega32 , both communication is through SPI...I use the Ethernet module enc28j60 continuously for communication between my computer and controller board...so
can i use this MCP 3208 here.. ?
can i use two type SPI module same time in a controller atmega32.. ?
i have I2C pin is free in my controller so is there is any DIP i2c adc available?
i am waiting for the suggestions of my friends.. thank you very much...

SPI is a bus. Many devices can connect to the same SPI pins. Wire all the SCK pins together, same with MOSI pins and MISO pins. Each device needs a separate chip select pin so that only one device at a time can talk with the controller.

i have I2C pin is free in my controller so is there is any DIP i2c adc available? if i am using more than 1 same adc ic interface by I2C how can i select a chip at a time , because in I2C chip is selected with i2c address if i use more than one same ic then all have same I2C address so i think there will be a clash between I2C address...how can i over come this problem
i am waiting for the suggestions of my friends.. thank you very much...

Google "DIP I2C ADC" and you get lots of hits. You just need to decide on resolution, number of channels, speed, etc.
