I'm pondering 15-bit (5 bits per channel) colour for my display logic instead of the current 12-bit.

I prefer 15 to 16-bit for true greys. 24-bit seems overkill and requires twice the storage.

A minor downside is the absence of the human-parseable hex values you get with 12-bit (0xFFC). 🎨

Just pushed some updates. I have posted the serial link code. This involved getting a set of scripts for simulation set up.

If anybody is interested in helping on this project, I'd love to have somebody try to follow the readme.md to install the prerequisites and run the ./run_sim script.

The goal would be to take notes and flesh out what things aren't in the prerequisite list and how to install them.

I'd be happy to do the same for somebody else's project.

I am happy to announce the release of a longwave software defined radio which I designed at work for experiments with #DSP algorithms, running on the #ULX3S #FPGA board. The user interface is based on #Mecrisp #Forth running on the #FemtoRV, and the signal chain contains a pipelined FFT designed by Dan Gisselquist. Many thanks to Ulixxe for their USB-CDC implementation!

Screenshot of the SDR in action, receiving maritime weather service NAVTEX on 147.3 kHz. On top of the image, there is a spectral waterfall display, on the bottom, the IQ components of the signal itself and their Fourier transform are visible.Hardware setup for the SDR in 1-bit conversion mode. Two USB cables are connected to the ULX3S board, along with a HDMI monitor cable and jumper wires to a small breadboard on which a few passive components for oversampling 1-bit analog-digital conversion using the LVDS comparator of a differential pair. The variable resistor is for setting the DC offset. Two jumper wires leave the image, the orange one carrying signal from the antenna preamp and blue for ground. One could also connect these two wires directly to the FPGA board, using the on-board 12 bit MAX11125 ADC converter.

I was just reading about #frugalComputing and found myself thinking of #Precursor

It feels to me like it would be a good fit for something like #deltaChat

Dear :
I'm trying to move an simulation from Rivera-PRO to Tachyon cvc64 in
I have a design with four "top levels" and cvc seems to chose the first one in the compile order. I would like to specify one explicitly.

I'm using the open version of the tool, so don't have paid support.

Documentation for this tool is... hard to find?

Can someone recommend a better tool? Or just show me where I missed in the documentation how to set the top?
