We are using an nrf51822 processor, running off of 2.7 volts from a switching power supply, powered with 12.4volts. The processor has simple gpio connections, and a battery...
Hi,
The structure nrfx_spim_xfer_desc_t contains both tx_length and rx_length fields.
Is there a situation where tx_length != rx_length ?
Thanks,
