    basic MPC3202 reading problem

    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.

    CV to teensy and vice versa

    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...

    Teensy 4.0 fingerprint for eagle cad?

    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?

    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.

    Teensy 3.1 crashes on trivial code

    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);

    Teensy 3.1, i2c and raspberry pi (4)

    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...
