RE: [avr-gcc-list] SPI troubles on atmega8

[Waldner, Ed]

Although your comment next to the SS_BIT pin states correctly that when in 
master mode (which seems like what you are trying to do) it should be 
configured as output, your DDRB assignment configures it as an input. It may 
not be the root cause of your problem, but it certainly contributes to a sickly 
behaving SPI interface.

Subject: [avr-gcc-list] SPI troubles on atmega8


Hi,

I am trying to get the SPI on my atmega8 chip to send 1 byte over the MOSI
line.
After doing the send I wait for the transmit complete flag in the SPI status
register
to be set.  For some reason the flag is not being set and I don't think that
any data is
being transmitted either.

I put the code I am using here:
http://www.rocketresearch.org/new/midi-light.c

It locks up right before the line:
       PRINT("byte sent");


cheers,
Jamie
