35ca538c18 Merge remote-tracking branch 'mossmann/master' into rad1o 
Just a very rough merge to get off the ground. Major parts are not yet
implemented. The mixer intergration is in a messed up state. Part which
need work have been marked with XXX

60b3ef3112 fix(sgpio): Fix rad1o HW bug which inverts RX Q 
As it is only inverted in the RX path (in respect to the HackRF) we need
to distinguish between RX/TX and inverted and not inverted.

5363ec3672 Use new GPIO API to abstract GPIO in various drivers. 
Had to do it all at once due to name conflicts with API exposed in libopencm3.
Quite invasive patch! Also precipitated an LED API...

422173a5f7 SGPIO: Add CPLD RX Q channel inversion, API to control. 2014-08-11 13:02:02 -07:00

0ab6a92ae6 Change SGPIO CPLD decimation API interface to be one-based (decimation of 1 to 8). 2014-08-11 13:01:50 -07:00

c6b1ec2979 Adjust SGPIO GPDMA trigger slice data to a single clock width pulse. Previously, it was 3 clocks long with a 4 clock period, which *seemed* to address GPDMA data drop-outs at maximum baseband speed (20Msps complex). 2013-12-31 20:27:14 -08:00

2fab6c40cd Extract SGPIO multi_slice configuration argument into an init-time function, so it doesn't need to be passed each time the SGPIO interface direction is changed. 2013-12-08 12:21:41 -08:00

50ec268794 Bracket SGPIO GPDMA slice configuration with multislice==false test. It only makes sense in single slice mode (until I have a clever idea for doing GPDMA with multiple slices). 2013-12-08 12:14:00 -08:00

e3f9e204c1 Relocate SGPIO pin configuration -- it only needs to be done once. 2013-11-20 13:22:19 -08:00

3bf6573dc6 Add skip-every-N function to CPLD, where N is controlled by three input pins from the microcontroller. 
Updated SGPIO CPLD testbench, as it had fallen a bit out of date.
Add SGPIO API initialization and control of CPLD decimation feature.

52dda32a18 Adjust logic in sgpio_configure() to treat transceiver modes outside TX and RX as RX. "OFF", for example... 2013-09-17 15:32:11 -07:00

cc5f1c61c7 Fix clock edge for TX mode. TX data was completely crapped up due to skew on my Jellybean/Lemondrop board. Hopefully, this also applies to Jawbreaker. I'll recheck once I have hardware in-hand. 2012-11-02 22:34:43 -07:00

9824a723b7 Moved invariant in sgpio_configure() loop out of loop. Originally, so I could use the value to calculate another invariant. 2012-10-12 09:45:18 -07:00

a1af4356b6 Reworked sgpio.c to make use of #defines for fields, instead of hard-coding shifts. Proper. 2012-10-11 20:46:21 -07:00

1bad2d8536 Consolidated two "deep" SGPIO configuration functions into one, qualified by transceiver mode (RX or TX). 95-ish % of the code was common. 2012-10-11 15:18:16 -07:00

8291d7fac0 Add SGPIO configuration function for "deep" (8-slice) TX mode. 2012-10-11 13:04:30 -07:00

5989465eb9 Add SGPIO configuration API and code, extracted from existing SGPIO projects. 2012-10-10 14:30:28 -07:00
