从以下结果看,程序猿的饭碗暂时还是很稳定嘛
编写蓝牙手柄操作的小game可以使用ESP32的Arduino开发环境来实现。首先你需要准备一个蓝牙手柄,然后将其与ESP32进行配对。接下来,以下是一个简单的例子,通过蓝牙手柄来控制小车的方向:
- #include <BLEDevice.h>
- #include <BLEHIDDevice.h>
- #include <HIDTypes.h>
- BLEHIDDevice* hid;
- BLECharacteristic* inputReport;
- BLEServer* server;
- const int ledPin = 2;
- int state = 0;
- void setup() {
- pinMode(ledPin, OUTPUT);
-
- BLEDevice::init("ESP32");
-
- server = BLEDevice::createServer();
- hid = new BLEHIDDevice(server);
- inputReport = hid->inputReport(1); // report number
- hid->manufacturer()->setValue("Manuf");
- hid->pnp(0x02, 0xe502, 0xa111, 0x0210);
- hid->hidInfo(0x00, 0x02);
- BLESecurity* security = new BLESecurity();
- security->setAuthenticationMode(ESP_LE_AUTH_BOND);
- hid->reportMap((uint8_t*)_hidReportDescriptor, sizeof(_hidReportDescriptor));
- hid->startServices();
- // BLE HID has been set up, now set up the rest of the service
- BLE2902* desc = new BLE2902();
- desc->setNotifications(true);
- inputReport->addDescriptor(desc);
- inputReport->setAccessPermissions(ESP_GATT_PERM_WRITE_ENCRYPTED);
- server->getAdvertising()->start();
- // Start bluetooth service
- hid->startServices();
- // Setup the input reports
- _hidReport[3] = 0x08; //Button state
- // Setup the LED output
- digitalWrite(ledPin, LOW);
- }
- void loop() {
- delay(1000);
- state = !state;
- digitalWrite(ledPin, state);
- _hidReport[0] = 0x01;
- _hidReport[4] = state;
- // Process button state
- inputReport->setValue(_hidReport, sizeof(_hidReport));
- inputReport->notify();
- }
复制代码 在这个简单的例子中,ESP32作为蓝牙手柄的控制器,发送蓝牙蓝牙信号。它可以用另一个ESP32读取和解释这些信号,然后应用于控制game中的动作。
