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.

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.

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.
