In our project 329, we need to use SPI. And we need to do it at 33MHz.
The plan is for Efika to be master and in 2-wire mode (MOSI, SCK)
After digging around this forum, and cross referencing with the MPC5200B User Manual. It looks bleak.
The IRDA pinout on Efika board are as follow:
pin 1 - VCC-3.3V
pin 2 - No Connection
pin 3 - Ir Rx - PSC6_0
pin 4 - Gnd
pin 5 - Ir Tx - PSC6_2
(Ref Efika User Manual - http://www.pegasosppc.com/manuals/Genes ... nglish.pdf
PSC6_0 also multiplex as Codec_Rx - or MISO
PSC6_2 also multiplex as Codec_Tx - or MOSI
PSC6_3 is missing which contains Codec Clk - or SCK
(Ref MPC5200B rev 1.3 UM pg2-78)
I figured the other alternative is to use PSC2 since http://www.powerdeveloper.org/platforms ... ifications
did not mention any specific usage on it. But where is it on the board?
On PSC2, we need the following:
PSC2_0 - MOSI
PSC2_3 - SCK.
(Ref MPC5200B rev 1.3 UM pg 2-41)
Most of the information was peeled from : http://www.powerdeveloper.org/forums/vi ... php?t=1268
If PSC2 is not available readily, how impossible is it to "hack" the board to pull the pinout from MPC5200B solder pads?
We are desperate. Only SPI have enough bandwidth to feed our microcontrollers with raw data.
