Re: [Paparazzi-devel] STM32 I2C watchdog

[Sergey Krukowski]

Hi, Heinrich!

Well I'm not really familiar with LPCs I2C architecture, but so far the  
current watchdog STM32 I2C recovery procedure is a mostly software  
solution, I think it could be applied to LPC architecture without big  
changes.

Best Regards,
Sergey
