CoreInk Button input related APIs and case programs.
Note:
Include
M5.update() function in the main loop to read status update and minimize blocking, otherwise you may not be able to retrieve the status of key changes in time.Example
#include "M5Unified.h"
void setup()
{
auto cfg = M5.config();
M5.begin(cfg);
Serial.begin(115200);
}
void loop()
{
M5.update();
if (M5.BtnA.wasPressed()) {
Serial.println("BtnA Pressed");
}
if (M5.BtnB.wasPressed()) {
Serial.println("BtnB Pressed");
}
if (M5.BtnC.wasPressed()) {
Serial.println("BtnC Pressed");
}
if (M5.BtnPWR.wasPressed()) {
Serial.println("BtnPWR Pressed");
}
if (M5.BtnEXT.wasPressed()) {
Serial.println("BtnEXT Pressed");
}
}API
The button part of CoreInk uses the Button_Class in the M5Unified library. For more APIs related to buttons, you can refer to the document below:
