MiCom Bug Thread

Thanks! I’ll gave this a shot, and I got an error that kinetis.h couldn’t be found…

Looks like I have a kinetis.h in my Teensy3.0 folder but not in my Teensy4.0 folder…

So I copied the kinesis.h over to the 4.0 folder, but now I’m getting the i2c_t3 error I posted about in the other thread.

Teensy 4 is not a kinetis architecture, copying the file over is most likely covering up a problem rather than fixing it. I don’t think ProffieOS is supposed to include kinetis.h for a teensy4 setup. Are you sure you’re using ProffieOS 7.14?

          #if !defined(USB_CLASS_MSC)
          // No mass storage, no mount_sd_setting
          #undef MOUNT_SD_SETTING
          #endif
          
          #ifdef TEENSYDUINO
          #include <DMAChannel.h>
          #include <usb_dev.h>
          
          #ifndef USE_TEENSY4
          #include <kinetis.h>
          #include <i2c_t3.h>
          #else
          // This is a hack to let me access the internal stuff..
          #define private public
          #include <Wire.h>
          #undef private
          #endif
          
          #include <SD.h>
          #include <SPI.h>

As you can see kinetis.h won’t be included if USE_TEENSY4 is defined, and USE_TEENSY4 is defined here:

          #define VERSION_MINOR 0
          #define USE_I2S
          #define AUDIO_CONTROL_SGTL5000
          #define USE_TEENSY4
          #define NO_BATTERY_MONITOR
          
          enum SaberPins {
            // Bottom edge (in pin-out diagram)
            // sdCardSelectPin is actually used, and can be altered if desired. 
            // needs an external 10K pullup to 3.3V, provided on audio shield
            sdCardSelectPin = 10,           // (See File->Example->SD->ReadWrite for
                                            // other possible values.)
          
            // these values are just a reminder not to use these pins for anything else,

So if it’s trying to include kinetis.h, there is something wrong with your config files or ProffieOS setup.

Thanks again!

I did a clean install of 7.14 and used the config file you referenced - the kinetis error is gone (must have been a copy and paste error…), so I’m back to where I was.

When you compile the teensy_audio_shield_micom.h, do you get the warnings I shared earlier? Or do you get a clean compile?

I think it compiled without warnings (but I’m not in front of that computer right now to verify). However, the warnings may depend on the optimization level, and/or the verbosity level set in the preferences.
