M5StickC Plus2 keystroke input related APIs and case programs.
StickCP2.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.
#include "M5StickCPlus2.h"
void setup() {
auto cfg = M5.config();
StickCP2.begin(cfg);
}
void loop() {
StickCP2.update();
if (StickCP2.BtnA.wasPressed()) {
Serial.println("A Btn Pressed");
}
if (StickCP2.BtnA.wasReleased()) {
Serial.println("A Btn Released");
}
if (StickCP2.BtnB.wasPressed()) {
Serial.println("B Btn Pressed");
}
if (StickCP2.BtnB.wasReleased()) {
Serial.println("B Btn Released");
}
}
M5StickC Plus2 library is based on the M5Unified library, the key part uses the Button_Class
in the M5Unified library, for more key related APIs you can refer to the following document:
