Iffy Signals Nov 29, 2019 - Minelab Vanquish 540 Depth & Recovery Test with 8" Coil

😞

There should be a slot for 8" floppy  somewhere. Or punch cards 🙂

8051 was my first true love 🙂 It had the whole 128 bytes of RAM

Rendered in real time..... you missed the vital part of it. A 16mhz 8bit processor can do it, not a 200+mhz 32bit Anyway, I'm not going to argue... really last time I'm speaking in this thread.

Look, you completely missed what i was saying before.

I worked a bit with ultrasound like signals, and all that signal processing stuff is quite similar to what is used in cases like Xterra and Equinox. Same dds-demod-multirate filter etc. So in our case one channel (I or Q) with DDS, demodulator and post demod mutltirate filter was consuming around 50 operations per sample with 32 bit integers. Actually some accumulators were wider than 32 bits, but not that important. Assuming that equinox processing is similar, works with four frequencies, has sampling frequency of 100kHz for simplicity, we are getting 80 millions of these calculations per second. It is already a significant portion of what M7 core can do at 200MHz.

You keeps assuming that all it does is scans buttons and lights up segments on display, which is completely wrong.

RTOS and rendering on a fly are not the same thing again.

Things are a little bit different when you need to do it in a real time. And for some reason you switched from amount of calculation to a file size. It's not the same thing.

Lots of other detectors process signals differently. Equinox, and I'm guessing Vanquish, is similar to Xterra. It performs quadrature demodulation and post demod filtering in a digital form. Xterra demodulates and postfilters only one pair of I and Q for receiver and one pair for transmitter, where equinox has to do at least as much for each frequency it processas. On top of that Xterra has a samplig frequency somewhere above 40kHz, where equinox needs to have it at least twice higher (remember highest frequency of 40kHz), which immideatly at least doubles amount of calculations done in processing for each frequency.

In terms of detector performance I'd say very likely no, I'm sure that's already overkill and the software will be written based on that CPU, I'd imagine they use it more for the fact it's easy to integrate Bluetooth and USB with it, it's designed to easily integrate both chipsets

It's not exactly clear if Vanquish uses the same CPU or not, but if it does, than I strongly disagree with this statement. No one would use a highly redundant part in a low-ish cost, high volume product.

stm32f745vgh6 I think

St32F745

It's actually F7. F745 or something like that.

Looks like it is available for shipping...

So... did you get the detector,  or just the t-shirt?  🙂

First of April ?

It's some kind of a gore vent. Just don't touch it and you will be fine.
