Missing serial out device file for logging

Troubleshooting and Support
1

Hi,

I previously was able to debug by examining logging output in one of the /dev files on Mac. The file was named something like /dev/cu.USB... I can’t find any files that contain USB or ACM0 in /dev. I can flash programs to Daisy Seed and the Patch_SM with no issues.

OS X: Sonoma 14.4.1, Mac M3
Same situation with Linux: Ubuntu 20.04.6 LTS

You need to enable USB serial. It’s done differently depending on if you’re using Arduino (DaisyDuino) or C++ (libDaisy).

Thanks,

Forgot to mention here is the relevant portion in my libDaisy code.

int main(void)
{
	hw.Init();
	hw.SetAudioBlockSize(4); // number of samples handled per callback
	hw.SetAudioSampleRate(SaiHandle::Config::SampleRate::SAI_48KHZ);
	hw.StartAudio(AudioCallback);

	AdcChannelConfig adc_config[NUM_ADC_CHANNELS];
	hw.adc.Init(adc_config, NUM_ADC_CHANNELS);

	hw.StartLog(true);
  	hw.PrintLine("Config complete !!!");

Is there something else I am missing?

It seems the code is hanging some point before I started logging. This works

int main(void)
{
	hw.Init();

	hw.StartLog(true);
  	hw.PrintLine("Config complete !!!");

	hw.SetAudioBlockSize(4); // number of samples handled per callback
	hw.SetAudioSampleRate(SaiHandle::Config::SampleRate::SAI_48KHZ);
	hw.StartAudio(AudioCallback);

	AdcChannelConfig adc_config[NUM_ADC_CHANNELS];
	hw.adc.Init(adc_config, NUM_ADC_CHANNELS);

StartLog(true) waits until USB is connected, then continues. StartLog(false) doesn’t wait.

Each has its uses.
