Hi, I would like that use a callback of timer (programmed with 10ms) to override the "ScreenView::handleTickEvent()" function, because this function has interrupt in ~14ms.
I managed to create the function and link the cpp and C files, but I couldn't use C++ functions (about graph..) in the timer callback that I created, there is an error like "was not declared in this scope" in which when I use it in the "handleTickEvent" function there is no error. Why is this happening?
Here is the .c file:
#include <gui/main_screen/MainView.hpp>
#include <math.h>
#include <stdlib.h>
extern "C" void CallbackTim5();
int slide_value = 0;
int xlabel_0 = 10;
int xlabel_1 = 11;
int xlabel_2 = 12;
int xlabel_3 = 13;
int xlabel_4 = 14;
int xlabel_5 = 15;
int xlabel_6 = 16;
int xlabel_7 = 17;
int xlabel_8 = 18;
int xlabel_9 = 19;
int xlabel_10 = 20;
int contDataPoint=0;
int msCounter=0;
//here dont works
void CallbackTim5(){
msCounter++;
// Insert each second tick
if (msCounter % 2 == 0)
{
// Insert "random" points along a sine wave
graph_control.addDataPoint(10);
graph_response.addDataPoint(20);
graph_setpoint.addDataPoint(slide_value);
contDataPoint++;
if(contDataPoint >= 300){
contDataPoint = 0;
if((xlabel_0 >= 300) && (xlabel_0 < 1000)){
