b78769a2ca This is a major architectural change. It's based on STM32CubeMX building a Makefile project with a lot of the configuration already done automatically. The reasoning being that they'll get right on the first try what I have to torturously fiddle with. And the result? With minimal effort, I already have a build that is more portable to develop on, uses the latest drivers, includes FreeRTOS, and I've already got DMA video working pretty much perfectly (though not 100% optimized and tested). This is also giving me a convenient opportunity to massively clean up my code and just a few tricks I've learned since writing the old code. So far so good!! BUT! It can't do any radio like things yet, none of that is implemented at al, no interface, no audio, etc. 2019-05-24 15:28:07 -06:00

14d70c8afd Semi working DMA code for the display driver! So excited! Now to work out the bugs :) 2017-06-24 23:42:12 -06:00

b3ee5db2b4 Saving current progress. Still some weird issues. Having trouble with I2C (again! It was such a pain to get working on the F4) and also something with the ADC I think.... I suppose it could be assembly issues of the F7 board too.... Hmmm. 2016-04-30 20:55:01 -06:00

7c84c19d01 Okay! I've got it compiling and largely running on the F7! Still not everything is right, but a lot of it is. I think I am almost there! Maybe I'll get to include the F7 after all :D 2016-04-26 00:21:16 -06:00

a24a6c6b8c I don't know if I am closer or further away. This stuff is hugely frustrating sometimes..... 2016-04-24 00:54:47 -06:00

86a5916626 Progress, I think. The thing compiles and builds something, but it's only 1K and won't run. Trying to figure out what I am doing wrong. :/ 2016-04-24 00:17:37 -06:00

57f3365484 Progress on copying stuff over for the F7. I am making quite a mess, I think I sure hope I can reverse this all if I need to!!! 2016-04-23 21:53:10 -06:00

4385f07394 Trying to get the PSDR code to run on the F7 chip. I'd like to use that one if I can. 2016-04-23 21:23:43 -06:00

a211a0b9dd A heroic effort to push things forward. Now working includes the I2C interface and the code to talk to and start up the frequency synth. Flip flops are on, frequencies are being divided. No luck on actually getting a signal all the way through though. I currently suspect the transformers or the mixers..... how high can a quadrature sampling detector go again? :/ 2016-04-21 00:57:58 -06:00

1890b25a4f PSDR 2.5 prototypes are assembled. This commit includes notes for things I want to change or improve (in the notes section of the schematic) as well as preliminary code changes to make it work on this hardware. Display comes on, lots of the parts are working, but no frequency synth yet, so it's hard to know how well the design is working. 2016-04-18 22:11:10 -06:00

0d13c419cc Got trace statements though the debugger! Cool! And it was so minor. Also, fixed a weird issue with missing linker files (at least on this computer......) 2015-12-29 15:21:24 -07:00

43500cbef3 Honestly, it's been a while since I did any coding, with getting the kickstarter ready, so I don't actually remember what the state of the code is right now. I think I was working on getting the UART up so we can use the GPS. I'm commiting this as more of a backup than anything. 2015-03-06 22:54:22 -07:00

46c832e409 Pretty big improvements to bitmap drawing code, and waterfall display code. Also a hack to deal with the red-things-stay-red bug (it's not ideal, it just blocks the encoder tick() if the display is drawing, doesn't seem to effect the feel of the interface in a bad way. Beginning to include GPS support. Working on some other display speedups (DMA and 16bit transfers, both are currently disabled) 2014-10-15 09:31:08 -06:00

817dcff56e Enclosure 3D files, Assembly Diagrams and Assembly Guide. Also so work on getting the firmware compatible with the PSDR2 hardware. Probably some junk as well. Lots of files. 2014-09-28 20:40:01 -06:00

71b87a38d7 Added a crude Automatic Gain Control (AGC) that's happening on the audio output side. I want to add one for the RF side as well, but I'll need to change the hardware to do it. 
Also fixed some weirdness with the filter menu items.
Verified that the recent changes to applyCoefficients() function are good and necessary to the proper operation of the filter.

7b1da77c21 Haven't committed in a while :o . Currently waterfall is disabled while I work on audio processing. I am capturing, FFT, filter, IFFT, and output. It seems to be working partly. I don't think I am doing things right yet. 
Also, starting to implement the menu system. Oh, and fixed some indentation, so it looks like there was more changed to main() than there really was....

8c308e12c0 Got a timer up and going, and it's firing interrupts! Next up is to change the audio capture to use the interrupt and some buffers. Basically separate the display loop stuff. 2014-06-23 00:00:31 -06:00

ffcb904b66 Initial commit to GitHub. 
Includes the Source (as an Eclipse project) and the Hardware files (including schematic, layout, gerbers, and bill of materials.)

The firmware is extremely incomplete. At this point the DDS chips work (with controlled phase relationship), the LCD (with fast-ish SPI, scrolling, and GFX, modified from Adafruit's library), the encoder knob, and LED work.

The ADC is capturing, but not in a usable way, but it's enough to feed the DSP code and see a nice pretty waterfall. Timers, interrupts, and DACs are not working yet.
