Cardputer Button
M5Cardputer keystroke input related APIs and case programs.
Note:
Include
M5Cardputer.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
cpp
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
#include "M5Cardputer.h"
void setup() {
auto cfg = M5.config();
M5Cardputer.begin(cfg);
}
void loop() {
M5Cardputer.update();
if (M5Cardputer.BtnA.wasPressed()) {
Serial.println("Pressed");
}
if (M5Cardputer.BtnA.wasReleased()) {
Serial.println("Released");
}
}API
M5Cardputer 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:
