Thanks for the responses. I wanted to wait to reply till I had actually tried some of the suggestions and it took me a bit to come back to the project.
Anyways, I did try adding the bypass cap but it didn't make a...
116mA average current seems about right, if you're powering up some other stuff besides the Teensy.
Did a quick check here with a Teensy 4.0 on my desk. At 600 MHz is draws about 90mA. Stepping down to 528 MHz...
What's the benefits of the MC7805CDTG over the LM7805?
I just checked to make sure, according to Teensy specs, it is supposed to consume 100mA, so it looks right, especially because I'm not using any of the other...

The 8 RMII signals can remap to only 2 groups of pins. The other group is native pins EMC_19 to EMC_26. Unfortunately, EMC_19, EMC_20, EMC_21 have no routing to any pins. Those BGA pins simply do not have any traces...

Hello,

Are you re-calling begin() from that timer in the loop? I have the same problem and am wondering whether your solution is what I should also do. I assume that the enet_ready flag is something you added and you just...
Hello BriComp,
Wow thanks for the info. I have tried Visual Studio and a Arduino plug in, But not Visual Micro?? It was kind of clunky work with and much slower than Atom with Platformio. Early on I tried Notpad++....
Thanks for that. What a gotcha!

For the price ... i don't know .

This looks very cool! Any chance that complete, ready-to-use Jeannies will be sold, for people that have no soldering skills, like me?
And if that's the case, what would be the price?
Thank you, regards.

Yes, but as it updated quite often I am hesitate*to use it as it will wear down and cannot easily replaced. After some more thinking about it I might just move the CPU emulation from the main loop to another timer...

It's normal. If you do not have a cable connected it will hang forever.

At this moment, looks like Adafruit still has 50 in stock. Several of the distributors who sell Teensy 4.1 on Amazon also appear to still have some.

Teensy 4.0 is in stock. Only Teensy 4.1 ran out.

Yeah, OSHPark runs about 8-10 days with the default options. You do anything different (like black mask), it will take about 2 weeks.

If you're wanting to modulate the amplitude, you can run the outputs of your audio source and your LFO into the inputs of a Multiply object.

Not exactly the place to post this, but how are global supplies of the MIMXRT1062? i.e. what would happen if we ordered 1000 Teensy 4.0's per month for the next 10 months? And, we are considering the 4.1 for a next...

It says on the website that they won't be available until at least June due to the chip shortage. Both DigiKey and Robotshop have the Teensy4.1, but not that particular ethernet kit.
But the Teensy 4.1 isn't in stock, that means I have to buy it somewhere else, plus pay $10 to ship a $3.60 part. (Ethernet kit)
I was hoping to buy both items from someplace in Canada.
Yeah, I think I knew that, but I didn't recall it. It looks like pins 0-5, 7-8, and 30-33 are the Xbar pins. It would be helpful if the Serial library page mentioned this.
