Hello,
I have a question about SPI between C2000 mcu, TMS320F27027F and DRV8303.
If I try to read status register in Drv8303 by SPI, the SDO pin of Drv8303 stayes high
level and doesn't response to the SPI signals.
I checked about these issues:
The En_gate signal is High.
The Spi_nCS pin is Low .
The Spi_clk signal is driven by the TMs320f27027f and the frequency is 1MHz.
The data on SDI pin is H'8000 ( read status register) .
The voltage on the Vdd_spi pin is supplied correctly.
Could anyone reply to my question ?
