I'm on implementation of a driver for a targeted platform.
ADXL345 is working well with SPI 4 wires-mode full-duplex (both reading and writing).
But I cannot make it work perfectly with SPI 3 wires-mode half-duplex (writing is OK, reading is not).
The specification (datasheet) is not really clear for SPI 3 wires-mode (attached image).
Was there anyone on implementation with SPI 3 wires-mode halt duplex please?
It must be great if any sample source code as well.
Thanks a lot.
