Sorry, I don't have any real experience with a Mac. Since it is just a matter of substituting files in the Teensy folders, can you find the appropriate place on the Mac?

Yes... I'm working on it! Right now I have the SDR part (Audio processing, IQ generation etc) working in a stand-aloe config, and am concentrating of the RF hardware side (mixers. QRP linear amplifier, filters). ...

Thanks @Frank B. We may be a little OT, but this is certainly something I need to understand re the T4.x when it arrives. My understanding was that in a dual core machine, the two cores run completely independently...

Which is exactly what I am hoping to do for my AudioSDR software: run the heavy DSP stuff in the M7 core within the Audio Library framework, and the UI and display code in the M4, with shared memory for communication. ...

Another quick GitHub update: Just to let you know that I"ve just uploaded another update with minor changes: 1. A more recent version of the manual (with source code for BareBonesWSPR) 2. An EXTRAS folder with the...

Definitely a +1 for an accessible reset pin. On my current T4.1 project the MCU is sandwiched between two other boards, and I don't want to solder to the bottom of the T4.1, so I'm having to use a tongue-depressor to...

Updates: Hi everybody! I've been involved in a large ESP32 project (a stand-alone WSPR beacon, with 20+ units now deployed) for several months and away from the forum, but still working on AudioSDR, and using it...

@MarkT I'd be interested to know how (and try) to do it. DMA? Certainly I can see a processor based frame buffer, but just writing a 256x(say)80 screen region pixel by pixel with 16 bit pixels and SPI speed seems...

@Clarkie1234 I sent you a very brief reply to your PM suggesting we correspond via email. I have a working 44.1kHz wide spectrum display for my audioSDR that works with Teensy 4.0/4.1, but I haven't even tried to put...
