Arduino for STM32

stan

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 ...

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

#include <Goertzel.h>
int sensorPin = PA6;

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.

so I made modification
// Set things up
//http://play.fallows.ca/wp/radio/ham-radio/signal-analysis-morse-decoder/
#include <Goertzel.h>
int sensorPin =PA6;
//int sensorPin =A0;
int led = PC13;
//int led = 13;
//const float TARGET_FREQUENCY = 500;
const float TARGET_FREQUENCY = 5000;
const int N ...

With new IDE the error is;

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.

This is what I did.

#define SAMPLES 128
#define SAMPLING_FREQUENCY 1000
int valuePin = PA7;
int Value ;

void setup()
{
pinMode(PA7, INPUT);
Serial.begin(250000);
}

void loop() {
int i;

Value[i] = analogRead(valuePin);
for(int i=0; i<SAMPLES; i++)
{
//FFT(data, 64, 100); //to get top ...

How to replace the data by this ?

Code: Select all

 int valuePin = PA7;
 
void setup() {
 pinMode(PA7, INPUT); 

}

void loop() {
 Value = analogRead(valuePin);

}

Hi
I am trying to build an code for quadrature detector.

The first step is to use analog pin - PA7 - as input instead of - //Example data: ?

//Example data:
int data[64]={14, 30, 35, 34, 34, 40, 46, 45, 30, 4, -26, -48, -55, -49, -37,
-28, -24, -22, -13, 6, 32, 55, 65, 57, 38, 17, 1, -6, -11 ...

I put PB6,PB8 inside - void init_wave() - I got only sine

void init_wave()
{
int i;
for (i = 0; i < SAMPLES; i++)
{
val[i] = 40 + amp * sin(stp * i);
val1[i] = 40 + amp * cos(stp * i);
if ( val[i] < 40)
{
digitalWrite(PB8, HIGH);
}
else
{
digitalWrite(PB8, LOW);
}
if ( val1[i] > 40 ...
