• DAP
  • Debug Access Point
• DAPLink
  • Arm Mbed DAPLink is an open-source software project that enables programming and debugging application software on running on Arm Cortex CPUs. Commonly referred to as interface firmware, DAPLink runs on a secondary MCU that is attached to the SWD or JTAG port of the application MCU. This configuration is found on nearly all development boards. It creates a bridge between your development computer and the CPU debug access port. DAPLink enables developers with drag-and-drop programming, a serial port and CMSIS-DAP based debugging.

G

• GPIO
  • General Purpose Input-Output

I

• IDE
  • Integrated Development Environment
• IRQ
  • Interrupt Request

M

• MCU
  • MicroController Unit
• microcontroller
  • a compact integrated circuit designed to govern a specific operation in an embedded system. A typical microcontroller includes a processor, memory and input/output (I/O) peripherals on a single chip.

P

• PDM
  • Pulse Density Modulation
    • a method of representing an analog signal with binary (on/off) data
