px4dev	82f72b96de	Move DMA start for tx/rx into the gap where SCL is still stretched so that there is no risk of receiving the first byte before DMA starts.	2013-01-25 21:35:32 -08:00
px4dev	b34311915a	Safeguard against back-to-back transactions while setting up to handle a register read request.	2013-01-23 18:56:58 -08:00
px4dev	f3a587dfce	Wire the I2C device code into the register handler.	2013-01-15 00:40:41 -08:00
px4dev	4e38615595	Major workover of the PX4IO firmware for I2C operation.	2013-01-13 19:05:01 -08:00
px4dev	1cecba2a86	Turn off i2c slave debug output for real.	2013-01-13 19:05:01 -08:00
px4dev	97136375e3	Turn off the I2C register dump at startup.	2013-01-13 19:05:00 -08:00
px4dev	4f285f7c80	Configure the DMA channels in circular mode so that we don't have to deal with the case where DMA stops but the master is still talking. ... Use AF as well as STOPF to decide when transfer has ended. We don't seem to get STOPF when we are transmitting.	2013-01-13 19:05:00 -08:00
px4dev	3cea0959b7	Implement a simple byte loopback server on I2C for more testing.	2013-01-13 19:05:00 -08:00
px4dev	2fb820fabd	I2C slave RX DMA works.	2013-01-13 19:05:00 -08:00
px4dev	0dab53ae26	Implement I2C slave DMA. Not working yet.	2013-01-13 19:05:00 -08:00
px4dev	7c2445f74d	Don't waste time printing when we have errors - that causes the master to time out	2013-01-13 19:04:59 -08:00
px4dev	811790a14f	Checkpoint I2C slave work on IO	2013-01-13 19:04:59 -08:00
