Hi there!
I am working on a Midi - CV/Gate module for my modular synth and figured the teensy 3.6 would be the perfect fit.
I am having a little bit of trouble using the t3.6 as a midi usb host, despite directly...
Funny, it was the only way that the 3.5/3.2 worked for me. I will have to give it another try. I'll try the 2 gnd trick just in case. Working on the house again, not the weather is nice :(.
Hi Tony.
Think you forgot to modify your begin function to adjust for T3.5/3.6 vs 3.2. The following should do the trick.

Hi, no thats not the problem.
In my case you can see in every letter are 6 black interspaces (missing pixel-rows). the result is: the letters are too large and i get only 4 rows of letters at the screen.

im sure someone might find 18 uarts and 3 usberials, 7spi busses, 12 wire busses, and ~180 gpio control useful lol :)

I see the amp object in the online version of the audio design tool but it doesn't look like it was included in Teensyduino 1.42 beta 3. It doesn't appear in the bundled audio design tool and, if I copy code into...
Looking at the memory map, I see there's a 1K memory block called "__malloc_av". That seems to be related to newlib's mallocr function, which uses, by default, a 4K page size. There's another, alternative malloc...
Thanks Don. Took me a while to break the code on to get it to read the data ready bit. But it seems to work. Now if I can figure out why the GPS is not updating :(

Don.
You got me worried for a minute:) I didn't see anyplace for them so....

Mike,
My plan is to add another 4-wire JST-GH connector, like I did for the GPS. But I'm waiting for my JST cables to arrive from mRobotics. So in the meantime, I'm doing some experiments without the slave, and...
Your code is using println, to output the text. println - is setup to output a trailing CR/LF type output to setup to start text on the next line.
Try using print instead of println for the last line.

Hi FrankB -
I'm having trouble getting the ILI9341_t3DMA library to work.

It does use PIN_13 for RX of ?? - but if that 'RX' isn't running the light won't indicate.

@defragster: As written in the OP, it's a project with a Teensy and an audio board. Doesn't the latter use pin 13 for audio data which would make the LED glow when flowing?
Looking at your code easy option does not work since the midi send is hidden off in the midi library, not being called by the main loop and no easy way to see if a send is in progress.
So looks like option B, ...

A teensy+prop shield package will not regulate the Vin, which is assumed to be 5V+/- 500mv. So while you can probably power a teensy 3.2 off 6V Vin, and have it regulated down to 3.3V ok (pushing the reg harder but not...

There is no default LED lit on a T_3.6. Please show your code - unless the program enables the pin 13 output and sets it high the LED is expected to stay off.

Just noticed this: https://github.com/BleuLlama/TinyBasicPlus/
It's not Lua but is written with arduinos in mind. Might work out of the box on the Teensy.
That's the idea
It is quite possible you will find up to 100 volts there, if you do second step is to add something like a 10K resistor between the grounds and see if the you just have capacitive coupling through the...

You need to test that there's a queue buffer available before copying data and sending it.
