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

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

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

d04d7845cf Initial transmit support. Internal microphone working. Capacitive touch sensors working. Currently touch TOUCH1 to transmit, waterfall changes color and shows the filtered output that should be transmitted (except that it's MUCH noisier than it looks, due, I think to DSP issues.) 2014-10-06 11:03:34 -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

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.
