bf297e0e08 I might've been a bit hasty removing volatile from transceiver_mode. 2013-09-07 22:01:46 -07:00

4ad3680428 Break SGPIO interrupt handlers in two -- RX and TX. 
Assign an SGPIO interrupt handler function at runtime, based on RX or TX mode. NOTE: This is incompatible with placing the vector table in ROM, which is fine on a device with no internal flash).
Remove SGPIO interrupt-time dependency on volatile transceiver_mode variable. Side effect is that a few cycles are probably saved inside the SGPIO interrupt.

b89f43e97e Replace transceiver_mode dependent MAX2837 mode management with max2837_mode() -> max2837_set_mode() calls. 2013-09-06 22:50:04 -07:00

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

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

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.
