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

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

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Updated SGPIO CPLD testbench, as it had fallen a bit out of date.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.

967e699815 Another little fix for the two's complement change -- initialize SGPIO data registers to DAC zero values. 2013-11-17 22:23:08 -08:00
Jared Boone
d006ec769c Updated CPLD bitstream with two's complement I/O and sample ordering fix. 2013-11-16 13:41:54 -08:00

06da7fd83a Reduce drive strength from clock generator (Si5351C) to first mixer (RFFC5072). This reduces every-50MHz spurs in RX by 10 to 15dB. 2013-09-22 11:54:37 -07:00
Jared Boone
314b3cdc7b Don't put MAX2837 into shutdown mode -- powering up takes a bit too long (500us for PLL to stabilize). Will need to revisit, because the MAX2837 chews up significant current (35 to 45mA) when not in shutdown. 
Remove excess calls to max2837_start() and max2837_stop().
 2013-09-22 11:52:45 -07:00

b4f883595f Remove MAX2837_FREQ_NOMINAL_MHZ #define -- it must be updated now that IF is adjustable. So I pushed the calculation directly into the two places it was used. 2013-09-21 20:27:27 -07:00
Jared Boone
2ed5c9d057 Consolidate hackrf_usb and hackrf_usb_rom_to_ram projects -- with generation of SPIFI binary by default. 2013-09-20 20:16:49 -07:00
Jared Boone

82ce660932 Broke some application-specific USB code into separate files within hackrf_usb/. Hoping I can use them as necessary in other projects, or push them into a library eventually. 2013-09-19 19:51:32 -07:00

04e70483a2 Move RF path configuration to early in the tuning process -- before the MAX2837 is tuned. 2013-09-17 21:59:01 -07:00
Jared Boone
1ec9f560b4 Move more RF path stuff (initialization and MAX5864 state management) into rf_path.c. 
Changed initial RF path mode to lowest power (OFF).
Remove initial MAX2837 IF setting -- it's a waste of effort when the first (and necessary) tuning operation will reset it anyway (perhaps to a different value).
 2013-09-17 17:25:00 -07:00
Jared Boone
b92e916b21 Forgot an #include in rf_path.c, from moving MAX2837 code. 2013-09-17 15:36:59 -07:00
Jared Boone
53415a620d Allow set_transceiver_mode(OFF) to fall through the rest of the function, now that sgpio_configure() is expecting OFF as a value. 2013-09-17 15:33:07 -07:00
Jared Boone
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
Jared Boone
0e8e3c8d53 Push MAX2837 state management into rf_path_set_direction(). 2013-09-17 15:27:16 -07:00
