Using mbed libraries¶
The mbed library provides the C/C++ software platform and libraries to build your applications. Note: Not all platforms have the resource required to implement these APIs or have them implemented.
- mbed Memory Model - The memory model used by the mbed Library
- RTOS Memory Model - The memory model used when the mbed-rtos is included in a program
- AnalogIn - Read the voltage applied to an analog input pin
- AnalogOut - Set the voltage of an analog output pin
- DigitalIn - Configure and control a digital input pin.
- DigitalOut - Configure and control a digital output pin.
- DigitalInOut - Bi-directional digital pins
- BusIn - Flexible way to read multiple DigitalIn pins as one value
- BusOut - Flexible way to write multiple DigitalOut pins as one value
- BusInOut - Flexible way to read/write multiple DigitalInOut pins as one value
- PortIn - Fast way to read multiple DigitalIn pins as one value
- PortOut - Fast way to write multiple DigitalOut pins as one value
- PortInOut - Fast way to read/write multiple DigitalInOut pins as one value
- PwmOut - Pulse-width modulated output
- InterruptIn - Trigger an event when a digital input pin changes.
- Timer - Create, start, stop and read a timer
- Timeout - Call a function after a specified delay
- Ticker - Repeatedly call a function
- Serial - Serial/UART bus
- CAN - Controller-area network bus
Real-time Operating System¶
- LocalFileSystem - Using the mbed disk as storage from within a program
- SDFileSystem - Using the mbed disk as storage from within a program
- USBDevice - Using mbed as a USB Device
- USBMouse - Emulate a USB Mouse with absolute or relative positioning
- USBKeyboard - Emulate a USB Keyboard, sending normal and media control keys
- USBMouseKeyboard - Emulate a USB Keyboard and a USB mouse with absolute or relative positioning
- USBHID - Communicate over a raw USBHID interface, great for driverless communication with a custom PC program
- USBMIDI - Send and receive MIDI messages to control and be controlled by PC music sequencers etc
- USBSerial - Create a virtual serial port over the USB port. Great to easily communicate with a computer.
- USBAudio - Create a USBAudio device able to receive audio stream from a computer over USB.
- USBMSD - Generic class which implements the Mass Storage Device protocol in order to access all kinds of block storage chips
- USBHost - Using mbed to act as USBHost
