Re: [Paparazzi-devel] aspirin 2 and LPC

[Prof. Dr.-Ing. Heinrich Warmers]

Hi all,
i made just  an  implementation of  the MPU6000 in the LPC2148 based HB-MINI.
Currently i have only connected the SPI bus. But it seems to be a problem to use the magnet sensor on the second local i2c bus of the MPU6000 chip.
It is currently not possible to config the  magnet sensor. Therefore we have to implement a software i2c for the pins of the spi interface. First  using the software i2c. Them config the magnet sensor by closing  the i2c bridge  in the MPU6000  and then switch to the spi mode. Currently i have also resistor switch to connect the magnet sensor to the main i2c of the lpc2148 chip. But it is then  not possible the use the inside CPU of the MPU6000 chip.

Cheers Heinrich

If I understand correctly, it is possible to use the aspirin2 module with the aspirin_i2c subsystem, but for fixed wing only…Am I right ?

we already flew it: https://github.com/tudelft/paparazzi/tree/master/sw/airborne/modules/sensors

 

it used an aspirin2 module on i2c

Hi Cedric,

I don't think there are any problems in principle that prevent you
from using Aspirin2 on the LPC (via SPI).
But the architecture dependent part hasn't been written for the LPC21
so far... When libopencm3 integration is ready (with the improved spi
driver https://github.com/paparazzi/paparazzi/issues/147) there should
actually be no need for arch parts in these drivers anymore.

Cheers, Felix
