Zephyr app to drive the X-NUCLEO-NFC08A1
This is a Zephyr-based firmware repo. Read the getting-started guide here: https://docs.zephyrproject.org/latest/getting_started/index.html
This repo is using Workflow 4: Application as the manifest repository, as described in https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.6.0/nrf/dm_adding_code.html#user-workflows
This repo is NOT to be cloned directy from git!
Use it with Zephyr's west metatool, e.g.:
mkdir vouch-zephyr-nfc08a1
cd vouch-zephyr-nfc08a1
west init -m [email protected]:vouchio/zephyr-nfc08a1.git
west update
For more information about west, see https://docs.zephyrproject.org/1.14.0/guides/west/repo-tool.html
By default, the hardware and software are configured for SPI. The following changes are required for I2C.
Reconfigure the X-NUCLEO-NFC08A1 for I2C by doing the following:
- Solder pin headers onto the SCL and SDA connections (ST2 and ST4) and add jumpers.
- Cut traces related to SCLK and MISO (ST5 and ST6 jumpers), and optionally add pinheaders so they can be-rejumpered for SPI mode.
- Solder 1.65 kΩ pullup resistors R116 and R117.
- Move resistor R205 to R204 so that I2C_ENAB is pulled low.
- Change
prj.confto specifyCONFIG_SPI=n,CONFIG_I2C=y, andCONFIG_RFAL_USE_I2C=y - Revise the board overlay (in the
boardsdirectory) to uncomment the I2C devicetree configuration and comment the SPI configuration.
cdto the application directory.
E.g.:
cd /path/to/vouch-zephyr-nfc08a1/vouch/apps/nfc08a1
- Build using west. The first time, the board needs to specified:
west build --board=nrf5340dk_nrf5340_cpuapp -p always
or
west build --board=nrf52840dk_nrf52840 -p always
or
west build --board=nucleo_l053r8 -p always -- -DOVERLAY_CONFIG=nucleo_l053r8.conf
Next time, you can just invoke the build command:
west build
- Flash or debug your application:
west flash
# or
west debug
