Re: [Paparazzi-devel] LIS302DL accelerometer on STM32F4_discovery board

[Michel GORRAZ]

Hi Felix,

And what about a driver for a PIC16F1828?

Price is less than 1$ and porting Paparazzi in assembly must not be such a big deal for you...

Hi Felix,
what do you think about a driver for the STM32F3?
There exists a solution for openpilot  (https://github.com/lilvinz/OpenPilot/wiki/How-to-build-the-discovery)  and pitxhawk
You need only a barometer and a GPS (currently < 14 Euro for the navilog ttl407) module  to make it.
A autopilot electronic below 50 Euro.
The new  pitxhawk use the STM MEMS sensors and the nuttx OS.

Regards

Heinrich

Hi,

I started writing a driver for the LIS302DL accel which is on the STM32F4_discovery board.

However I can't even seem to read back the device id from the WHO_AM_I register via SPI1 and now I've run out of time that I can spend on this.

The driver is basically done, but obviously there is still an error somewhere (either in the SPI mcu_periph for SPI1 on the F4, or the lis302dl_spi driver).

If someone wants to continue on this, it is in my lis302dl branch on github:

https://github.com/flixr/paparazzi/commits/lis302dl

I've added a test_lis302dl target to the stm32f4_discovery_test.xml airframe file.

Cheers, Felix
