ADC of Zilog Microcontroller

[akoangsimula]

guys can u help me with this one?thanks in advance!!

how to configure your microcontroller to accept eight (8) analog inputs. The analog inputs are all derived from eight potentiometers.

A user selects the analog input to be sampled by using the keypad. Keys 1 – 8 are used to determine which analog input will be sampled. Keys 0 and 9 are disabled. Key “*” commands the microcontroller to start sampling the analog input and display the results in the 7-segments while “#” terminates the command and awaits from the user for another analog input to be sampled.

Dear you can use ATmega128 controller it has build in ADC. you can interface Keyboard easily with any port.
Rest of the thing will be done in programming.

thanks for the response but we are instructed to use z8f6421,,

here i have attached the Z8 series user manual and ADC coding....
Take a look at it and do it...

hope its useful for u.....

thanks...y does it have a printf?..we used a 4x3 keypad for the output display, for example:
Key “*” commands the microcontroller to start sampling the analog input and display the results in the 7-segments while “#” terminates the command and awaits from the user for another analog input to be sampled..

how it would be in the code...thank you...

Hi akoangsimula,

For your hardware problem, I think IRC Slimboard can help you. IRC SlimBoard

Just investigate on it. Your hardware problem is already addressed by that product. That is available here locally.

Hope this helps.
