4cc865de54 Swapped constant names for HackRF VID and PID. Fortunately, I also had them backward in my call to libusb... Now the names are right! 2012-10-15 15:55:44 -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.

c0cb64f316 Add support for TX mode. 
Add getopt control of RX or TX mode.

fb9ce63f7f Add (manual) switch for TX and RX mode. 
Add code for configuring TX mode.
TODO: Consolidate lots of repetitive code.

693e61b31c Removed block of assembly in favor of C code. TODO: Look at assembly and compiler -O options to avoid assembly. 2012-10-10 16:17:02 -07:00
Jared Boone
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

09b768631e Tragic, but simple and effective libusb test program for reading data from the HackRF bulk IN endpoint, and dumping it to a file. 2012-10-10 15:22:41 -07:00
Jared Boone
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).
