Well, if code looks fine then some extra checks are required. Make sure ground connection is not done using long wires. Make sure Vdd is seriously decoupled using Low pass low impedance RLC filter, try add a 100 uH coil in series with Vdd but tight to groundon both ends using not only 47uF and...

Hi, just went on DSP route Hilbert coefficients and having problems understanding the math involved. I see PT8211 is 16 bit R-2R , but according to a simple sampling law, any signal must be sampled at minimum 2 times the highest signal freq. Are you sure the sampling is done at 44000 Hz for CD...

I am a bit disappointed by audio shield design. :mad: It seems that stereo audio jack ground a is virtual ground , aka floating ground not connected to teensy GND. (1.7 V diff and also is paint marked on botom too) .Therefore I have fried my audio shield but lucky me there are some companies in...

I aint see a way to reply except "reply with quote" , sorry about ! Did you set heating each room using floor heating system or using plain heat radiators with dallas temp sensors to cutoff each room when setup temp is True +- 0.2 C ? I mean, all of us should go green while is not too late (...

Well, this is a long time debate. I usually tend to use max 75 of 100% as safety zone, so a 1A power source will do just nice. I even powered this display from laptop USB via TTL usb to serial converter but it is risky indeed. I just ordered my first Teensy ever , a 4.1 one for my hamradio...

10.1 " intelligent and capacitive one does not draw 2A but 0.773 Amps at 5V. I did measure it on a UNI-T lab power supply.
