ElectronutLabs Papyr

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 ElectronutLabs

Configuration

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

[env:electronut_papyr]
platform = nordicnrf52
board = electronut_papyr

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

[env:electronut_papyr]
platform = nordicnrf52
board = electronut_papyr

; change microcontroller
board_build.mcu = nrf52840

; change MCU frequency
board_build.f_cpu = 64000000L

Uploading

ElectronutLabs Papyr supports the next uploading protocols:

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

Default protocol is blackmagic

You can change upload protocol using upload_protocol option:

[env:electronut_papyr]
platform = nordicnrf52
board = electronut_papyr

upload_protocol = blackmagic

Debugging

PIO Unified Debugger - “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).

ElectronutLabs Papyr does not have on-board debug probe and IS NOT READY for debugging. You will need to use/buy one of external probe listed below.
