Re: [Paparazzi-devel] SPI transaction queue driver for Lisa/M and other STM32F10x based autopilots

[Gautier Hattenberger]

Hello Andre,

This is very interesting, could you at least push your work to a public 
repository and send us the link ? You can also make a pull request (into 
4.0_beta seems a good idea) but it will probably need more work before 
actually merging it as we also need the lpc21 support for this need driver.
