Using ChibiOS's I2C driver standalone

Actually it seems that I spoke too soon. I am using the following spinlock to wait for the hardware to do its job, but the loop simply goes on forever. Any ideas on why this might be?

Code: Select all

while (TWCR & 1 << TWIE)
        ;

Yeah, trying to use the driver before enabling interrupts is really going to help. I can't believe how long it took to find that bug.
