Serial (UART) drivers
- BufferedSerial: A class for serial data transfers so a device can interface with another device (such as sensors, printers or another board) to exchange data or to send text to be displayed on a text-based computer interface.
- UnbufferedSerial: Similar to BufferedSerial, but intended for applications that are short of RAM and cannot afford buffering or that need more control of the serial port and use it from IRQ.
- QuadSPI (QSPI): Provides functionality to configure and access QSPI devices connected over a QuadSPI interface.
- SPI: Communicate with SPI slave devices, such as FLASH memory, LCD screens and other modules or integrated circuits.
- SPISlave: Communicate with a SPI master device.
- AnalogIn: Read an external voltage applied to an analog input pin.
- AnalogOut: Set the output voltage of an analog output pin, specified as a percentage or as an unsigned short.
- BusIn: Combine a number of DigitalIn pins to read them as a single interface instead of individually.
- BusOut: Combine a number of DigitalOut pins to write them as a single interface instead of individually.
- BusInOut: A bidirectional bus that supports up to 16 DigitalInOut pins that you can read and write as one value.
- DigitalIn: Read the value of a digital input pin.
- DigitalOut: Configure and control a digital output pin.
- DigitalInOut: A bidirectional digital pin.
- InterruptIn: Trigger an event when a digital input pin changes.
- PortIn: Define which pins of a hardware GPIO port are set as an input and to read the value of those pins.
- PortOut: Define which pins of a hardware GPIO port are set as an output and to write those pins.
- PortInOut: Read and write an underlying GPIO port as one value.
- PwmOut: Control the frequency and duty cycle of a PWM signal.
- USBAudio: Send and receive audio data over USB.
- USBCDC: Emulates a basic serial port over USB so you can send or receive data.
- USBCDC_ECM: Emulates an Ethernet interface over USB so you can send and receive Ethernet frames.
- USBHID: Turn an Mbed board into a Human Interface Device (HID) that can send and receive messages over USB.
- USBKeyboard: Send key presses, check the status of control keys and send a key press sequences though a stream interface.
- USBMIDI: Send and receive MIDI messages over USB using the standard USB-MIDI protocol.
- USBMouse: Emulate a mouse over the USB port. You can choose relative or absolute coordinates and send clicks, button state and scroll wheel movements.
- USBMouseKeyboard: Emulate a mouse and a keyboard at the same time so you can send both key presses and mouse movements.
- USBMSD: Emulate a mass storage device to store or load data to and from a storage chip, such as SDcard or Flash.
- USBSerial: Emulate a serial port over USB. You can use this serial port as an extra serial port or as a debug solution.
- CAN: Controller-Area Network (CAN) is a bus standard that allows microcontrollers and devices to communicate with each other without going through a host computer.
- Flash IAP: Flash In-Application Programming (IAP) interfaces with the MCU's internal flash memory.
- I2C: Communicate with I2C devices such as serial memories, sensors and other modules or integrated circuits. This class is for the I2C Master.
- I2CSlave: Communicate with I2C Master devices.
- MbedCRC: Provides support for Cyclic Redundancy Check (CRC) algorithms.
- ResetReason: Fetch the reason the system restarted.
- Watchdog: Set up a hardware timer that resets the system if it is not refreshed periodically.
