Observation: same code + electronics work fine on a teensy 4.0.

Hi,

I'm trying something very simple: reading samples from an MCP3202.
I can't get it to work.

#include <SPI.h>
#include <Mcp320x.h>

#define SPI_CS 10 // SPI slave select...

Hang on; I saw this earlier with an arduino uno I only realised! (talking serial through usb to a host system) I thought it had to do with an uart filling up but an usb-buffer makes more sense.

Ah that I did not know. That indeed helps a bit.

The problem did not disappear yet.
I ordered another LC that I'll use solely with software-tests, e.g. not with new hardware. So that I know that...

Hi,

I designed some hardware: 2 analogue inputs (-5...5V), 4 digital input (one for which I forgot to add a voltage divider). It also has a din midi plug.

Maybe this will work: http://vanheusden.com/Teensy4.zip

jscircuit says this works:...

Hi,

I'm trying to migrate a schematic I made around an arduino (nano) to teensy lc.
This schematic converts a "control voltage" (-5...+5v) to ADC levels (0...5V) and the output of an MCP4725 to...

But not the pin-out I think?

Hi,

I'm looking for a Teensy 4.0 fingerprint for eagle cad. I do not require the "difficult" pins at the bottom.
Or is there a way for converting kicad automatically to eagle cad?

thank you!

Hi,

Will the teensy platform support c++17? (from within the Arduino ide)

Good point.

I'd like to add that i2c with RPI 3 and earlier probably won't work due to the clock-stretching, but from what I've heard (but not verified yet) the rpi4 should be fine.

I can't remember. I had them "in stock" for a couple of years.

Hmmm it must be broken then.
Sad!

(it works fine on a teensy 2.0)

Hi,

I've uploaded some trivial code to my teensy 3.1
It compiles and flashes fine but after +/- 0.5 seconds it crashes.
Any ideas?



void setup() {
Serial.begin(115200);

Never mind, I should've done more googling first.

Hi,

The raspberry pi (at least version 3 and older) has this problem with clockstretching in i2c. Communication then doesn't work with the avr arduino (maybe other arduinos as well, have not tried...
