bab6ec5fef Move buffer allocation to before enabling CPLD I/O, so as not to mess up I/Q synchronization. 2012-06-15 16:16:05 -07:00

9a53fd3a07 New CPLD .svf. 
Change Si5351C CLK2 to 10MHz.
Keep CLK3 at 20MHz, but not inverted.
Source SGPIO8 from P1_12 instead of P9_6. (See "SGPIO Clock Routing") modification at https://github.com/mossmann/hackrf/wiki/Future-Hardware-Modifications ).

f08fc3bb51 Pulled SSP1 configuration for MAX2837 into hackrf_core. Added SSP1 configuration for MAX5864. Added #defines for manipulating CS of both MAX parts. Changed a couple of #define names to be consistent with other names. Added explicit manipulation of MAX2837 CS via GPIO. 2012-06-14 13:06:10 -07:00

878936645d Corrected my correction of my misunderstanding of how SGPIO_CTRL_ENABLE works. Turns out I *can* immediately disable a slice using ENABLE. If I want to synchronously disable a slice, I do it via DISABLE. And if I want to screw up my code, I (unwittingly) set all slices to synchronously disable, then configure SGPIO and watch my slices run once and stop. :-( All better now. 2012-06-14 11:30:03 -07:00
