Yes it took my hours to find the problem

The solution replace .h by .cpp in #include <AnalogBufferDMA.cpp> and remove //#if

Hai I try to use the adc_timer_dna and I recieve the error message : Arduino:1.8.13 (Windows 10), TD: 1.53, Board:"Teensy 4.0, Audio, 600 MHz, Faster, US English" C:\Users\GEBRUI~1\AppData\Local\Temp\arduino_build_119014\sketch\ADCadc_timer_dma_V5.ino.cpp.o: In function `setup'...

Hai I am building a ultrasound device using an two analogous mems microphone circa 85 KHz. The analogous part contains two microphones and a distance of 1 or more meter between them. I like to do simultaneous readings from the analogues input channels and calculate the direction and distance...

Hai Richard I think it is a mistake to say that the tinsy has 4 harware encoders ports. I can not find that kind of ports I think it is a software limitation. Perhaps this limitation is due too build into the software library. I think that is because timing considerations, that is the most...

Hai There is now a good external sound card based on the ALC4050 chip and I like to connect this dongel to a teensy 4 for ultrasound processing. I am looking for a way to connect a realtec Alc4050 type-C external sound card to a teensy 4 The ALC4050 dongel can operate at a verry high...

Hai I working on a closed loop stepper configuration using a linear scale. I use a teensy 4 withe the encoder and that is working fine. Now I need to monitor the puls signals and direction pin to the stepper driver. The goal is to compare the theoretical position of the xaxis and the measured...

Hai I need a 5V power to supply to a circuit. I wonder, in case I supply 5v by the micro USB if I can use the pin left of the micro usb, right to the gnd between the 5V in and 3V in pins. It seems that, that pin has a 5 V level ????? That pin is not explained in the specification sheet I have...

Thanks, I will show the results John

Hai I recently have a linear scale for my home made CNC machine. I wonder if a can use this library for a linear scale it has the A and B pins and a R pin. I think the R pin is triggered at the beginning of the scale. The resolution of the linear scale is 1/1000 mm. I have a teensy 4 and...
