The sample demonstrates a functionality of nrfx_twim and nrfx_twis drivers, when TWI transfer is performed in the TX-TX mode.
The sample supports the following development kits:
| Board | Support |
|---|---|
| nrf52dk_nrf52832 | Yes |
| nrf52833dk_nrf52833 | Yes |
| nrf52840dk_nrf52840 | Yes |
| nrf5340dk_nrf5340 | Yes |
| nrf54l15dk_nrf54l15 | Yes |
| nrf9160dk_nrf9160 | Yes |
Application initializes nrfx_twim and nrfx_twis drivers. The main purpose of this sample is to emulate a situation, in which you write data to a particular register of the slave (usual controller -> sensor communication using two wire interface). The sample works as a simple simulation in which you can communicate with a drone by defining X, Y, Z forces and sending some additional data.
m_drone_reg is used as an internal register map of the drone. In the first write operation (TX1), define a register number to which data from the second write operation (TX2) will be saved.twim_handler() is executed with relevant log messages.twis_handler() is used to prepare data for sending and updating particular registers of m_drone_reg.For more information, see TWIM driver and TWIS driver - nrfx documentation.
To run the sample correctly, connect pins as follows:
LOOPBACK_PIN_1A with LOOPBACK_PIN_1B.LOOPBACK_PIN_2A with LOOPBACK_PIN_2BRefer to pin definitions in
common/nrfx_example.h.
You should monitor the output from the board to check if it is as expected.
To run this sample, build it for the appropriate board and then flash it as per instructions in Building and running section.
You should see the following output:
1.12.0
