Delta DFBM-NQ620¶

Hardware¶

Platform Nordic nRF52: The nRF52 Series are built for speed to carry out increasingly complex tasks in the shortest possible time and return to sleep, conserving precious battery power. They have a Cortex-M4F processor which makes them quite capable Bluetooth Smart SoCs.

Configuration¶

Please use delta_dfbm_nq620 ID for board option in “platformio.ini” (Project Configuration File):

[env:delta_dfbm_nq620]
platform = nordicnrf52
board = delta_dfbm_nq620

You can override default Delta DFBM-NQ620 settings per build environment using board_*** option, where *** is a JSON object path from board manifest delta_dfbm_nq620.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:delta_dfbm_nq620]
platform = nordicnrf52
board = delta_dfbm_nq620

; change microcontroller
board_build.mcu = nrf52832

; change MCU frequency
board_build.f_cpu = 64000000L

Uploading¶

Delta DFBM-NQ620 supports the following uploading protocols:

• blackmagic

• cmsis-dap

• jlink

• mbed

• nrfjprog

• stlink

Default protocol is cmsis-dap

You can change upload protocol using upload_protocol option:

[env:delta_dfbm_nq620]
platform = nordicnrf52
board = delta_dfbm_nq620

upload_protocol = cmsis-dap

Debugging¶

Debugging - “1-click” solution for debugging with a zero configuration.

You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

Delta DFBM-NQ620 has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
