reel_board

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 and are the most capable Bluetooth Smart SoCs on the market.

Microcontroller NRF52840
Frequency 64MHz
Flash 1MB
RAM 256KB
Vendor PHYTEC

Configuration

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

[env:reel_board]
platform = nordicnrf52
board = reel_board

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

[env:reel_board]
platform = nordicnrf52
board = reel_board

; change microcontroller
board_build.mcu = nrf52840

; change MCU frequency
board_build.f_cpu = 64000000L

Uploading

reel_board supports the next uploading protocols:

  • blackmagic
  • cmsis-dap
  • jlink
  • mbed
  • nrfjprog
  • stlink

Default protocol is cmsis-dap

You can change upload protocol using upload_protocol option:

[env:reel_board]
platform = nordicnrf52
board = reel_board

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).

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