Hello everyone, I have been going crazy for days around a noise problem on a project that I am carrying out. I am in an advanced test phase of a Eurorack module with Teensy 4.1 associated with the SGTL5000 codec (the diagram is directly taken from the Audio Board PRJC) The teensy also controls...

Hello everyone, I'm trying to interface the TLC5940 to teensy 4.0. I used the pins shown on this page: https://www.pjrc.com/teensy/td_libs_Tlc5940.html where, for design reasons I used pin 9 instead of 7 for the SCLK signal. the pins to be reassigned with respect to the base pins of the...

Thank you very much, the project is very interesting. I'm going to read it all!

Yes, I would like to make a multichannel system using the audio board codec, using the Teensy audio library. cannot the audio data (TX&RX) always be sent on the same bus based on the selection of the right codec via the CS pin? Do they have to be separate for each individual codec? Thanks

Goodmorning everyone. Checking on the datasheet and on the diagram of the Audio Board, I saw that it is possible to interrupt the communication pins TX and RX to mount two audio boards on the same teensy. This is because communication takes place on the I2C BUS and the codec can only have two...

thanks, I try with a 100 uF capacitor and a 100 nF on USB host power line, but nothing changed. I try with another keyboard, the Arturia Keystep, that have external power supply connector. If I connect the external power supply the noise is like the phone charger. The problem I think is the...

Hello to everyone, I start a project of synth with teensy 3.6 via its internal dac. I found a simply sketch to try the MIDI to synth connection. I connect on USB Host port an ARTURIA MINI LAB MK2 MIDI CONTROLLER. The power supply is only from teensy USB via computer. The system work well but I...
