Low-level communication firmware provides programming and debugging communication between host development tools and supported PSOC target devices. The firmware uses industry-standard SWD and JTAG debug protocols with CMSIS-DAP Bulk and HID USB transport modes. Bridge functions support USB-UART, USB-I2C, USB-SPI, and GPIO communication with target hardware. DAPLink mode adds mass-storage drag-and-drop programming, CMSIS-DAP debugging, and a USB CDC virtual serial port for supported kits.
