MityDSP-L138F - External SPI access from "Industrial IO Development Kit"
Added by Mathew Jones almost 9 years ago
Hi
We're developing ARM software using ThreadX on the MityDSP-L138F (i.e. with FPGA), which resides on the "Industrial IO Development Kit".
We want to interface from the ARM to several off-board SPI devices but looking at the pin assignments on J700, J701 & J702 it initially looked like neither SPI0 nor SPI1 came out from any of these connectors, however I did notice that SPI1 is actually on J700 as it is shared with CAN, which we don't use.
- Pin 11 (CAN_CLK) for SPI1 Clock
- Pin 13 (CAN_SIMO) for SPI1 SOMI
- Pin 15 (CAN_SOMI) for SPI1 MOSI
- Pins 19-22
Regards
Mat

Hi Mat,
If you are using a board with a revision 1E or higher (see the Industrial IO Revision Information), then you can use the J700 pins for the SPI as you would like. We brought the SPI pins out to that connector after the initial design was released, and it appears that we did not catch the change in the datasheet. I am sorry for the confusion.

That's great. We're using the 80-000268RI-2B so should be able to use those SPI1 pins.
Thanks for clarifying that.

Hello Mike,
I am using 80-000268RI-3B. but there are no update in the following link regarding the update
https://support.criticallink.com/redmine/projects/indio/wiki/Industrial_IO_Revision_Information
Which revision I can refer to for my board?
thanks

Updated to contain info on 3B and 3C.
