Hello, I have found an implementation of the Goertzel algorithm that contains code that I don't understand. And more specifically the pre-calculation of coefficients. :pensive_face: At the top of the code there is :#define DTMF_697Hz 27980 #define DT...
Hello everyone,we currently devolping an Class D amplifier with the sta309a as DSP and TAS5624A from TI for amplification.We face a issue with random levels of noise appearing after power up sequence.This may be an issue of wrong configuration during...
When I am changing the number of channels to 1 channel.it is recognized by the windows driver, but the"advanced" TAB is disappear (unlike 2 channels configuration). Did someone faced with this kind problem? Do I missedsomething? of course, audacity d...
I have an integrated one of an ultrasonic washing machine.This when measuring its frequency oscillates in 80kHz, but after a few minutes it begins to decrease the frequency and increase uncontrollably, so I have decided to change it.the question is t...
Good day!I want to use STA309A.I want to signal MCLK (XTI) 256*Fs, bicki to signal 64*Fs.What frequency of PWM will I get, 384 kHz or 256 kHz?Real exampleFs = 32 kHzMCLK (XTI) = 256 * Fs = 8192 kHzBICKI = 64 * Fs = 2048 kHzWhat is the frequency of th...
Hello, hopefully this is the right place to post this.I am trying to use the Biquad Design Tool (v1.0.0.0) that is described in the Birquad Library UM1625 manual as part of the X-CUBE_AUDIO firmware package. I'm trying to generate a simple bandpass f...
Please share the recommended schematic for STA321MPL1.
How are you?I would like to test an ultrasound pulser IC evaluation board (STEVAL-IME012V1) on Windows 10 PC. I installed a test software (STSW-IME011) to configure waveforms (frequency and number of pulses) for the evaluation board. However, I have ...
Battery Fuel Gauge via STM32.Whether provide test code?
I like everything about the TS92X series, I just need to know if there are any issues with operating the TS92X series with dual supplies (+5/-5V).
