Plug An Arm i/f

[ddlawrence]

Hi. I am thinking of getting an Plug An Arm for general learning.
Will it fit on an Plug A Pod interface board? It looks like it will to me.

Yes, so far all the Pluga's follow the same pattern as close as we can. I didn't layout the ARMs so there is some variance. Some signals are not available in the same places, thinking of the PWM in particular with this statement. But many are, like the SPI we try always to have on the same pins.

The ARMs aren't as well supported now. We lost our ARM expert and have been unable to replace him due to the economic conditions. Other than that, they are very popular and have many wonderful features.

For what it's worth, I've been playing a LOT with my Pluga2138. I set up a small Excel spreadsheet for Pluga2138 and Tini2138 pins to help me follow what goes where and what the alternate functions are on the pins.

I have used it by sorting by Physical-pin, J-pin and Px.x port pins. Then I decide which pins I can use for which function. I attached a copy of it in case you would like it as a reference.

I've gotten Timer0, Timer1, UART0, UART1, PWM 4,5,6, AD1 working.
I have code for SPI and I2C, but no applications for them yet.
AD0 code didn't work, but I ported the AD0 code to AD1 and that worked. Hmph.

I didn't get EINT2,3 working, but the code is there. I used a pair of GPIOs checking every 10milliSec for changes from 0->1 to increment a counter and that works, so I may not bother trying to get EINTx working.
