Re: [Paparazzi-devel] spi related errors during compile time

[Felix Ruess]

Ok, thx.
Then I will still add a meaningful error message to our HAL, if you want to use spi0 with that...
If someone wants to implement spi0 to work with our HAL, this can be removed again.

Cheers, Felix

Hi Felix,

just saying SPI0 is usable and used. No interrupts, no HAL

Hi Martin,

how/where is the spi0 ISR, etc. then defined in this logger firmware?
Does it use our mcu_periph/spi HAL?
If not, I would still add a more informative error message if you try to
use spi0 with mcu_periph/spi on the LPC.

Cheers, Felix
