e7c6408473 Add comment describing SWITCHCTRL pins vs. RF path configurations. 2013-09-07 20:21:43 -07:00

d65314db37 Clean up switchctrl code a bit -- redundant #ifdefs and complex if conditions. 2013-09-07 20:20:48 -07:00

bafe97e302 Extract knowledge of RF path configurations from the RFFC5071 driver. 
Change initial RF path mode to SWITCHCTRL_SAFE. (Previously started at SWITCHCTRL_SAFE and then immediately switched to SWITCHCTRL_AMP_BYPASS.)

518c46a111 Oops, missed a spot where I should've called a MAX2837 mode function. 2013-09-06 23:09:29 -07:00
Jared Boone
b89f43e97e Replace transceiver_mode dependent MAX2837 mode management with max2837_mode() -> max2837_set_mode() calls. 2013-09-06 22:50:04 -07:00

a367f84d15 Add MAX2837 mode set/get functions. 2013-09-06 22:29:57 -07:00
Jared Boone
a5c0b5deeb Add MAX2837 functions to control operating mode. 
Replace direct manipulation of GPIOs controlling MAX2837 with operating mode functions.

7c5db57f02 Hide the MAX2837 intermediate frequency behind a function. It also prevents leakage of the freq_*_cache variables. 2013-09-06 16:46:03 -07:00

266003f3af Added two CGU debugging tools: 
- check_clock.py to decode the frequency monitor result.
- dump_cgu.py to display selected CGU registers in a legible format.

6c0d803647 Cleaned up management of SGPIO and transceiver mode state vs. USB configuration state. This should help with power management. It may also be necessary when operating at low speed (48MHz), to keep the SGPIO interrupts from chewing up ALL available CPU cycles. 2013-09-04 16:27:43 -07:00

1f5b979fd9 Added usb_set_configuration_changed_cb() call that bgamari fixed in his as-yet-unmerged USB branch. 2013-09-04 16:24:19 -07:00

d76d72665e Adjusted cpu_clock_pll1_low_speed() to operate at 48MHz, as per several comments with the code. The actual MSEL value was previously selecting 84MHz. 2013-09-04 16:23:32 -07:00
Jared Boone
237bf6ecdb Pulled redundant PLL1 initialization code from cpu_clock_init(). Called cpu_clock_pll1_low_speed() instead. 2013-09-04 16:22:41 -07:00

24ed48d93a Fix for "issues/62 fix PLL1 overclock bug" see hackrf_core.c -> cpu_clock_init() 
Fix for "issues/78 startup current too high" see hackrf_core.c -> New functions cpu_clock_pll1_low_speed()/cpu_clock_pll1_max_speed() & hackrf_usb.c to switch low_speed/max_speed.

9f2dca3e4e usb_standard_request: Always call configuration_changed_cb 
For reasons I don't entirely understand, bulk requests are suddenly
ignored after a SET_CONFIGURATION request (even if the configuration did
not change) unless the endpoints are reinitialized. This is done by
configuration_changed_cb, therefore we call it for every request.

5a70772295 usb_queue: Enable transfer chaining 
Unfortunately this seems to be slightly broken. While hackrf_transfer
streams fine, things fall apart when disabling streaming. Not sure why
yet.
