1bec883f80 Add baseband sampling frequencies useful for 48kHz audio output. 2013-12-31 20:05:26 -08:00
Jared Boone
9f2260237b Add GPDMA LLI functions to create a loop or one-shot chain of LLIs. 2013-12-08 18:18:22 -08:00
Jared Boone
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
Jared Boone
6185b67008 Add GPDMA LLI function to enable interrupt after LLI operation is complete. 2013-12-08 17:49:50 -08:00

Jared Boone
d2fd5e74c5 Change SGPIO DMA configuration API from dividing up a buffer's length into M parts to creating a chain of M transfers of size N. 2013-12-08 13:05:30 -08:00

Jared Boone
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
Jared Boone
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
Jared Boone

3e7ff530d7 Add GPDMA API. Should go in libopencm3 when it's more fleshed-out. 2013-12-07 15:28:59 -08:00
Jared Boone
5468a01a9b Forgot to include rf_path.h now that its pin setup is called from hackrf_core. 2013-11-21 10:23:53 -08:00

Jared Boone
9db166427f Remove I2S pin definitions, since they're too specific for generic/shared HackRF code. 2013-11-20 15:46:53 -08:00
Jared Boone
f453e4c377 Bump libopencm3. 2013-11-20 15:44:15 -08:00

986e4dec93 Massive rework of Makefile_inc.mk, to support building of heterogeneous (M4+M0) binaries, and easy switching between RAM and SPIFI-bootable builds. Constructive criticism welcome -- I'm sure there's better ways to do this. 2013-11-20 15:28:28 -08:00
Jared Boone
02ba23bf68 Fix broken sgpio-rx project, broken due to massive changes to how RF path and tuning is done. 2013-11-20 15:24:50 -08:00
Jared Boone
893c20e41f Fix naming problem with SGPIO test project. This is due to my use of VPATH in Makefile_inc.mk, which I'm starting to regret a little bit... 2013-11-20 15:24:14 -08:00
Jared Boone
552dbe4a6d Add sgpio.c to C files, now required for pin initialization. 2013-11-20 15:23:26 -08:00

6a03f157ff With Makefile RAM/SPIFI option, remove/rework redundant "rom_to_ram" projects. 2013-11-20 15:21:40 -08:00
Jared Boone
c365d0a37e Add memory regions for M0 code to live. In the "rom_to_ram" (SPIFI) version, put M0 binary in ROM. In the RAM version, put M0 code in the destination RAM region. 2013-11-20 15:14:13 -08:00
Jared Boone
31a55d0e9b Assembly file that includes M0 binary into a .o to be linked into the M4 binary. There's certainly a more elegant way, but for now... 2013-11-20 15:13:18 -08:00
Jared Boone
e29ec6b084 Add default M0 code that just loops forever, if a project doesn't specify any SRC_M0_[CS] files. 2013-11-20 15:11:54 -08:00
