Re: Goertzel for stm32f103 LCD
I am trying different frequencies, i think this is not issue, with 40000 the highest input frequency = 2000 Hz, 1 bin is 312Hz wide..... So sampling frequency is changing the numbers but this doesn't make the Goertzel work or not.

Re: Goertzel for stm32f103 LCD
Thanks for link. now I have to make it shorter , it has 1760 lines, I think just tone detect part will be about 100 lines.fredbox wrote: ↑Fri Dec 18, 2020 7:58 pmYou might find some useful info here: https://github.com/jmharvey1/STM32_CWDecoder. The tone detection has been solved using a timer interrupt.

Re: Goertzel for stm32f103 LCD
Here is fft bin 12 = 3.6kHz, and SAMPLING FREQUENCY 40000, so I put 40000 to Goertzel but nothing changes. In fft LCD is responding to PA6, numbers are jumping without signal from noise in Goertzel on LCD is 28.3 steady. #include "arduinoFFT.h" #include <LiquidCrystal.h> LiquidCrystal lcd(PB15, PB5,...

Re: Goertzel for stm32f103 LCD
it is compiling but not working I added LCD, in uno LCD it is alive in stm32 it is dead just displays 0.00 and do on respond to signal on PA6. // Set things up //http://play.fallows.ca/wp/radio/ham-radio/signal-analysis-morse-decoder/ #include <Goertzel.h> int sensorPin = PA6; //int sensorPin =A0; i...

Re: Goertzel for stm32f103
Thanks it is done, no errors. For some reason I have higher space usage
Code: Select all
Sketch uses 25352 bytes (38%) of program storage space. Maximum is 65536 bytes.
Global variables use 3960 bytes (19%) of dynamic memory, leaving 16520 bytes for local variables. Maximum is 20480 bytes.

Goertzel for stm32f103 LCD
Hi This program is working fine with arduino uno, for blue pill there is compiling error. I looked at Goertzel.h but I didn't find something special which can cause the problem. Here are, program, error, Goertzel.h file. // Set things up //http://play.fallows.ca/wp/radio/ham-radio/signal-analysis-mo...
