The first one to guess how many IOs exist on FEZ Cobra gets a free one. You need to tell us exactly how many IOs and how did you know how many!
This is very easy one and we expect a guess very shortly.
Update: we also need to know how many analog pins are there, how many interrupt pins and how many PWM pins!!
Matt and Chris, sorry you can’t participate. You guys already have won
6 taken by SD card Interface and if you used the same scheme as as the emx dev mofule none are interrupt pins
So that leaves 70 to start with
7 Analog
6 PWM All digital
6 interrupts that are also analog
33 interupts that are digital
63 would be the suspected digital available at this time.
1 Com/usb Ports 2 interrupt 2 regular digital each
Which take the above numbers down to
31 interrupt pins and
61 digital pins
maybe another 1 Com/usb Ports 2 interrupt 2 regular digital each
Which take the above numbers down to
29 interrupt pins and
59 digital pins
Then if we take out maybe can loader stuff or bootloader and what not that is 2 more digital pins and 2 more interrupt pins.
So 57 Digital pins or 59 if only using 1 com port.
and 27 interrupt pins or 29 if only using 1 com port.
Next if you still have the LCD driver stuff included and consider that separate that is 20 more digital pins gone and 10 more interrupt pins by the EMX dev design.
Which could mean
47 Digital PIns
7 interupts.
After that.
So it could be any of those stages Depending on how far you want someone to break it down and how much you put into said device. Since all we know it base chip set and nothing more it is not as easy as you would think depending on how the firmware is configured and you have segmented out the board.
So there is my pulling it out of my butt guess :> i am done staring as spec sheets and design files for the day thank you. :>
Yeah I was on the same page as you before i edited my post i noticed the analog out a few lines above the IO0…
Good luck either way. Not like i wont own it like the other 10-12 micro controllers laying around the house I have. From propellers to arduino to pure avr butterflys and pics, 3-4 versions of stamps plenty to play with a choose from depending on the situation.
So the analog can both be used as digital and analog and the other things i listed from the spec.
Total I/O removing buttons and led analog + digital = 48
Total I/O including buttons and led analog + digital = 52
9 P0.25 IO6* ADC2/COM4 ADC2 (10Bit Analog to Digital Input) or Serial port (UART) TXD transmit signal (Out) for COM4.
10 P0.26 IO7* ADC3/ DAC/COM4ADC3 (10Bit Analog to Digital Input) or DAC (Digital to Analog
31 P0.12 IO45* ADC6 ADC6 (10Bit Analog to Digital Input).
32 P0.13 IO46* ADC7 ADC7 (10Bit Analog to Digital Input).
33 P1.31 IO47 ADC5 ADC5 (10Bit Analog to Digital Input).
very very very close! You are right about AOUT being shared with an AIN on the same pin. This was missing before but there is one last thing that no one noticed just yet.
It maybe very difficult to find but we want to see if someone would find it.
I guess, If I ask. How many InputPort objects I can make without getting an exception then what would the answer be? The LED wouldn’t make sense on Input Port but let us pretend it is okay.
