Hello, everyone
I just want to display the analog voltage value on Touchgfx using STM32H735g-dk, but the textAreaBuffer just didn't update the value that I want it to show, my code are as follows:
�?Model.cpp】
#include <gui/model/Model.hpp>
#include <gui/model/ModelListener.hpp>
#include <cmsis_os.h> //add
extern osSemaphoreId binarySemAnalogHandle; //add
extern uint16_t uhADCxConvertedValue[10]; //add
Model::Model() : modelListener(0)
{
}
void Model::tick()
{
if(binarySemAnalogHandle != NULL) //add
{
if(osSemaphoreWait(binarySemAnalogHandle, 100) == osOK)
{
analogUpdatepresenter();
}
}
}
void Model::analogUpdatepresenter() //add
{
uint32_t sum = 0;
uint32_t average = 0;
for(int i = 0; i < 10; i++)
{
sum += uhADCxConvertedValue[i];
}
average = sum / 10;
modelListener->analogUpdatepresenter(average);
}
�?Screen1Presenter.cpp】
#include <gui/screen1_screen/Screen1View.hpp>
#include <gui/screen1_screen/Screen1Presenter.hpp>
Screen1Presenter::Screen1Presenter(Screen1View& v)
: view(v)
{
}
void Screen1Presenter::activate()
{
}
void Screen1Presenter::deactivate()
{
}
//average is passed through the same variable from Model.cpp using modelListener
void Screen1Presenter::analogUpdatepresenter(uint32_t average)
{
view.analogUpdateview(average);
}
�?Screen1View.cpp】
#include <gui/screen1_screen/Screen1View.hpp>
#include <string.h>
extern uint32_t average; // newly add
extern uint16_t uhADCxConvertedValue[10];
Screen1View::Screen1View()
{
}
void Screen1View::setupScreen()
{
Screen1ViewBase::setupScreen();
}
void Screen1View::tearDownScreen()
{
Screen1ViewBase::tearDownScreen();
}
void Screen1View::analogUpdateview(uint32_t average) // average is coming from view.analogUpdateview from Screen1Presenter.cpp
{
memset(&textAreaADBuffer, '\0' , TEXTAREAAD_SIZE); // clear the textAreaADBuffer to all zeros
//Unicode::snprintfFloat(textAreaADBuffer, TEXTAREAAD_SIZE, "%.3f", average * 0.000805664);
//Unicode::snprintf(textAreaADBuffer, TEXTAREAAD_SIZE, "%.d", average);
//Unicode::snprintf(textAreaADBuffer, TEXTAREAAD_SIZE, "%s", touchgfx::TypedText(T___SINGLEUSE_F1FW).getText());
Unicode::snprintfFloat(textAreaADBuffer, TEXTAREAAD_SIZE, "%.3f", average * 0.000805664 - 0.132); //3.3/4096 = 0.000805664，4096_12 bit register
textAreaAD.invalidate();
}
Besides, I can get the average while I am debugging, but the final value"average * 0.000805664 - 0.132" just didn't go inside the textAreaADBuffer, anyone has any idea about it? Thank you in advance!
