ATMEL AVR ATMEGA8535 Micro controller Trainer

[engineerpervez1]

I am preparing a AVR ATMEGA8535 Trainer it has following
specification.
LCD Display with back light with contrast adjustment.
4 digit 7-segment Multiplexed disply
2 Nos analog inputs (one LDR and other analog voltage by Potentiometer
4 Nos of digital inputs isolated with opto coupler (Like PLCs Inputs)
8 bits digital output capable handling 500 mili Amp 24 volts
5 Volt regulator on board.
One real time clock chip
2 nos of Relay outputs
Infra red communication.

it is 80 % complete if any body interested in it, I will send more detail

Hi,
Haven't you placed any LEDs or a buzzer? I think there should at least be 8 LEDs and one buzzer with provision to connect them directly at the output of the ATMEGA8535.
You could also have at least one switch (momentary or latched) that pulls a pin low when pressed. Just a suggestion....
Could you let us know some more details?

Hope this helps.
Tahmid.

yes 8 LED indication I forget to write.
yes one pizeo buzzer.
and RS232 communication.
Four opticaly isolated inputs
one input out of 4 inputs is on interrupt.
and 2 analog outputs.(these are PWM outputs).
No latched input sorry.

Hi,
It sounds nice. Can we see the design?

 

[engineerpervez1]

yes, my camera has some battery charging problem, let me solved it, I will post the complete
design with the schematic diagram.
