App	Description
audio_loopback	Pushes stereo PCM to the EK-RA8D2's on-board DA7212 CODEC over SSIE0, driven entirely through the board layer's audio bring-up rather than a hand-rolled SSIE sequence. Sound comes out of the AUDIO ...
motor_3phase	Runs GPT0/1/2 as a synchronized three-phase PWM triple with a dead-time pair on each channel, sweeping the duty cycles through a sine table. It is written for an external gate-driver IC.
threadx_https_client	ThreadX plus NetX Duo plus Mbed TLS: one worker thread brings NetX Duo up on a static IPv4 address, dials a hard-coded HTTPS peer, completes a TLS handshake and dumps the head of the response to the ...
threadx_nimble_peripheral	A GATT Battery Service peripheral built on the Apache NimBLE host stack running over Eclipse ThreadX, glued to the ra8_ble transport by the adapter under port/nimble/. That adapter is the point of ...
threadx_sdcard_demo	A ThreadX bring-up smoke test: two threads at the same priority blinking two different LEDs at two different rates. It exercises this repo's ThreadX port glue – the low-level init that sets the ...
usb_audio_device	Brings the USB Full-Speed controller up in device mode through the hand-written ra8_usb stack and enumerates the board as a USB Audio Class 1.0 device, feeding a precomputed 1 kHz sine into the ...
