7920490f1e Change USB bulk endpoint for baseband data to have only one queue item. Since there are only two baseband buffers, and one is transferring with the codec and the other with USB, enqueueing more than one buffer at a time would result in transferring an incomplete buffer. 2013-12-31 20:34:01 -08:00

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

fc5ec03353 Adjust tuning API to use a single 64-bit integer for frequency in Hz, since the Cortex-M4F has good support for uint64_t. 2013-12-31 20:12:47 -08:00

7f35ceaff2 Set Si5351C CLK7 output to drive LPC GP_CLKIN at 40MHz, so that activity (e.g. audio) on the LPC can be synchronized with the baseband sample rate. 2013-12-31 20:09:44 -08:00

5b59f9cb0a Change GPDMA channel clli member to uint32_t, casting to/from gpdma_lli_t and dealing with the multiple fields was driving me crazy. 2013-12-08 18:16:58 -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
