Delta DFCM-NNN40

Hardware

Platform Nordic nRF51: The Nordic nRF51 Series is a family of highly flexible, multi-protocol, system-on-chip (SoC) devices for ultra-low power wireless applications. nRF51 Series devices support a range of protocol stacks including Bluetooth Smart (previously called Bluetooth low energy), ANT and proprietary 2.4GHz protocols such as Gazell.

Configuration

Please use dfcm_nnn40 ID for board option in “platformio.ini” (Project Configuration File):

[env:dfcm_nnn40]
platform = nordicnrf51
board = dfcm_nnn40

You can override default Delta DFCM-NNN40 settings per build environment using board_*** option, where *** is a JSON object path from board manifest dfcm_nnn40.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:dfcm_nnn40]
platform = nordicnrf51
board = dfcm_nnn40

; change microcontroller
board_build.mcu = nrf51822

; change MCU frequency
board_build.f_cpu = 32000000L

Uploading

Delta DFCM-NNN40 supports the next uploading protocols:

  • cmsis-dap
  • mbed

Default protocol is cmsis-dap

You can change upload protocol using upload_protocol option:

[env:dfcm_nnn40]
platform = nordicnrf51
board = dfcm_nnn40

upload_protocol = cmsis-dap

Debugging

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

Warning

You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.

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

Delta DFCM-NNN40 has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.

Compatible Tools On-board Default
CMSIS-DAP Yes Yes
