ed1f3aec61 Fixed build of SAMV71-XULT/nsh. With the changes from 26f7b8c the build process of the default configuration did not succeed anymore. This is fixed by this commit. 2016-06-28 08:23:41 -06:00

26f7b8c9e5 TWIHS Driver improved and GPIO-Driver fixed for Open-Drain Pins 
- sam_gpioread: Now the actual line level from the pin is read back.  This is extremely important for Open-Drain Pins, which can be used bidirectionally
 - Re-Implemented twi_reset-function and enhanced it so it can be called from inside the driver (see next point)
 - Glitch-Filter: Added a configuration option to enable the twi-built-in glitch filter
 - Added a "Single Master Mode": In EMC Testing the TWI-Bus got stuck because the TWI-Master detected a Multi-Master access (but there is no second master). With the option "Single Master" we detect these events and automatically trigger a twi_reset. We also do an automatic recovery if a slave got stuck (SDA stays low).

With the above changes I²C-Bus reliability in harsh environments (eg. EMC) is greatly improved.

The small change in the GPIO-Driver was necessary because otherwise you cannot read back the correct line status of Open-Drain Outputs and this is needed by the twi_reset function.

fca329945b This patch ensures that the TWIHS (i2c) hw get's its clock set when the sequence of 
sam_i2cbus_initialize
sam_i2cbus_uninitialize
sam_i2cbus_initialize

Or twi_reset is called.

I found this a while back in the stm32 family, so there may be more arch-es with this sort of bug. I suppose any driver that has the notion of "do not set the freq if it is already set" could be suspect.
