MA 732 3 Wire SPI Compatibility

Is it possible to use the MA732 with half duplex 3 wire SPI, using MOSI and MISO tied together in one SDIO line? I have read elsewhere that it can function without MOSI but it would be preferred to retain the programable functionality.

Hello Liam,

I apologize for the delay in the response.

Unfortunately, the configuration you suggested would not work, (unless some additional circuitry is used). When CS goes low, the MA732 sends the angle information on the MISO line even if no command is received on MOSI. This means that the MA732 is always driving the MISO line when CS is low. If you connected MISO and MOSI, you would have both the controller and the sensor driving the same line at the same time.

Best regards,
