[Paparazzi-devel] Value of I2C_TRANSACTION_QUEUE_LEN

[Thomas Wuensche]

Hi all,

In sw/airborne/mcu_periph/i2c.h I2C_TRANSACTION_QUEUE_LEN is set
to 8. With my octorotor I find that the last motor is not driven
with this setting, but works if I increase it to 10.

Based on the code I think that value has to be at least one slot
bigger than the number of simultaneously scheduled I2C commands.

Should we have that value configurable in the airframe definition?
Should we have some plausibility checks against number of motors?

Regards, Thomas
