a65186f83c Merge pull request #11 from jboone/master
Lots of stuff related to getting TX data through the CPLD and DAC, intact.

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 ).

d68036f79d Eliminate ill-conceived HOST_CLK from CPLD.
Rearrange clocks to not use AC-coupled CLK1 from Si5351C.
Move CODEC_CLK to GCLK1, CODEC_X2_CLK (now HOST_CLK, too) to GCLK2.
Add trace on Jellybean PCB to connect GCLK2 to LPC4330 pin 56 (P1_12) -- a different SGPIO8.

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
