526a8e9e7a Add typed request return value that indicates request is OK or requires endpoint STALL. 
Changed vendor request to a lookup table, instead of an ever-growing switch statement.

e8b30f3489 Oops. Request handlers called from setup handler could access the IN side of the endpoint, which does not get a copy of the SETUP bytes. 
TODO: Make a single copy of the SETUP bytes, and provide a clean way to access those bytes regardless of whether you're holding the IN or OUT endpoint. (This was a problem in the IN complete handler, and probably other places, too.)

fc9632f19d Add code to control MAX2837 B1 through B7 from Jellybean. Another feeble attempt to control DC bias. 2012-10-17 22:28:10 -07:00
Jared Boone
143d845b05 Add code to control RXHP pin on MAX2837 (Jellybean only). I was hoping this would control the baseband DC offset problem, but no, it doesn't seem to help at all. 2012-10-17 21:48:41 -07:00

549c943979 Add USB control of LPF baseband filter. 
Add max2837_set_lpf_bandwidth() function to choose available LPF filter bandwidth based on bandwidth in Hz.
Change configuration of MAX2837 to set LPF_EN and FT at max2837_setup(), not in max2837_rx() or max2837_tx() (which was overriding prior filter configuration).

9c4a0e94b0 Factor out sample_rate_set() from cpu_clock_init(). 
Implement switching between several supported sampling rates for Jellybean and Jawbreaker.
Commit bits of the Si5351C USB request support that I apparently missed in a prior commit.

d4da08a3d7 Oops! Forgot to change MAX2837 mode from RX to TX when transceiver mode is changed. 
Initialize MAX5864 earlier, in "transceiver" mode (where both ADC and DAC are active), and then shift SSP1 into MAX2837 mode and leave it there, for faster tuning and RX/TX switching.

7fdfde9314 Make use of i2c0_init() argument to control duty cycle, when APB1 clock shifts from IRC (~12MHz) to PLL1 (204MHz). 2012-10-17 11:48:35 -07:00

57866227bf Remove weird LDSCRIPT that isn't necessary now. 
Change .bin generation to include only ROM-able sections.
TODO: Is there a better way to do the objcopy? It'd be great to put everything in the "rom" region into the .bin, instead of having to list out -j section for each of the sections that go to ROM.

168c92a3d0 Now that RxVGA gain control is working correctly, gain needs to be backed WAAAY off to get a usable capture in a fairly noisy 2.4GHz environment. 2012-10-13 11:07:17 -07:00

f4b6f08500 Fixed incorrect field with for MAX2837 VGAgain_SPI_EN field. For boards that have no B7:B1 connections, this could prove extra problematic...and for boards that do, but aren't driving those pins from the LPC. 2012-10-13 11:06:39 -07:00

8d14de21ce Fixed prior commit, where I lost the switch between endpoints based on RX or TX mode. 2012-10-12 09:46:49 -07:00

9824a723b7 Moved invariant in sgpio_configure() loop out of loop. Originally, so I could use the value to calculate another invariant. 2012-10-12 09:45:18 -07:00
Jared Boone
a1af4356b6 Reworked sgpio.c to make use of #defines for fields, instead of hard-coding shifts. Proper. 2012-10-11 20:46:21 -07:00

1b5574d2b9 RX and TX sample buffer loops turned out to be the same, so they're consolidated. 2012-10-11 15:19:01 -07:00

1bad2d8536 Consolidated two "deep" SGPIO configuration functions into one, qualified by transceiver mode (RX or TX). 95-ish % of the code was common. 2012-10-11 15:18:16 -07:00
Jared Boone
6f0fda0bee Moved transceiver_mode_t to hackrf_core.h. 
Changed transceiver_mode to volatile, since it's liable to be accessed at interrupt time.

fb9ce63f7f Add (manual) switch for TX and RX mode. 
Add code for configuring TX mode.

0253642b2e Added extern for usb_set_configuration() to eliminate compiler warning. TODO: Eventually, this should be just a callback, not the complete SET_CONFIGURATION implementation. 2012-10-10 16:15:12 -07:00

092c5b7b0f Removed removing of .usbram section from .bin file output. Because there's no more .usbram section! 2012-10-10 15:42:30 -07:00

155d81da4e Reworked USB code to pump SGPIO with an interrupt. 
Relocated USB buffers to be split across two AHB memory regions, so that USB endpoint priming doesn't choke SGPIO transfers.
Added code to configure 2.4GHz front-end.
Changed USB and SGPIO priority levels (probably unnecessary because sample corruption was due to USB priming bursts).

165997d09b Changed USB queue head and transfer descriptor attributes to be explicitly aligned, instead of targeting a section. 
Added miscellaneous internal USB functions.
Improved disabling of endpoints -- now clearing pending interrupts and flushing as well.
