Re: Measuring relative timing/phase of fast analog signals
Hi,
I'm a little lost on how to install the patch so I can use read_timed_multi() on pyboard v 1.1. I clicked the link to the guide and couldn't find it. Could you please point me in the right direction?
Thanks,
Kip

Re: Butterworth filters
Hi Peter, I'm new to digital filters and I was wondering if you could give me some guidance. I want a 10KHz bandpass filter and my ADC is sampling at 64KHz. I'm doing this with the read_timed() function capturing the data in a bytearray. Here's my problem, most of the digital filters for python impl...

PyBoard HC05 Android
It's a bit hacky, but I noticed some people looking for an example communicating with an android device via Bluetooth using an HC05 adapter and thought I'd upload my code. Code here: https://github.com/KipCrossing/PyBoard-HC05-Android It demonstrates being able to send and receive data. I attempted ...

Re: Wave generator AD9833 with the Pyboard
I'll keep it in mind when choosing.
Thanks a lot, Peter, you've been a great help

Re: Wave generator AD9833 with the Pyboard
Good spot Robert. I think I have the same board (little blue one without a MCLK pin). I do see 25 written on it. I used a trial and error method to find it out and I got approximately the same (a bit more than 25 MHz). I decided to include it for those who have boards with the MCLK pin - not that I ...

Re: Wave generator AD9833 with the Pyboard
I'm well aware that it can't handle such crazy speeds. Have a look again, I chose 16 MHz. Perhaps you accidentally added a 0 when reading it? In terms of the frequencies needing to fit 168/N, I don't see that anywhere in the documentation when using the freq argument. Perhaps this is common knowledg...

Re: Wave generator AD9833 with the Pyboard
Good pick up Peter, I was using the APB1 bus clock as an arbitrary rate. The AD9833 gets its clock reference via a timer into its MCLK pin. Unfautionately for me, the PCB that I bought does not have this MCLK pin and there is little information on what rate to use (but that's my problem). I've updat...

Wave generator AD9833 with the Pyboard
If anyone is interested, or need to produce waves up to 10 MHz, this might come in handy. "The AD9833 is a low power, programmable waveform generator, capable of producing sine, triangular, and square wave outputs and has a 0 MHz to 12.5 MHz output frequency range" The code may be found here: https:...
