Thanks!

It definitely is a bad design. I mean, MSP430 has an option 3 or 4 wire
mode. Hence saving the pin if the MCU is always a master. I guess Philips
ppl don't really care about SPI, since they are all about I2C. 

We'll see how it goes.. hopefully I'll find a neat workaround.

Cheers,

m.

Milos,

The SSEL pin must be pulled high from what I make of docs/posts. I put
external pullup on it to get working and am using GPIO lines for my CSs. I
was hoping to know like you if could use SSEL to CS (instead of GPIO) my
first SPI device to save a pin but work on higher-pri projects came up ...

Hi,
I was able to get it to work once I put the SSEL to High. is there a
possibility to get the SPI to work without having the SSEL signal. The
amount of pins is limited and wasting one of the pins like that is just not
an option.
Thanks a million,
m.

Hi everyone,
I'm trying to get the SPI module to work. The description seems very
straight forward, but for some reason I'm not getting any activity on the
SCK pin nor on the MOSI. 
Do I have to have SSEL also "selected" through the PINSEL block? The chip
will always be a master, hence I never need to change modes. But I have to
say that the doc is a bit fishy about that.
I was wondering if anyone has simple example of the SPI code just to compare
it with whatever I have.
Thanks in advance,
m.
