Hi Team,
Could you please kindly help to check if customer below SPI data is correct? Relate command should read 01h data(from cursor a to cursor b), default read back value should be 0500h, but from below purple waveform, it seems no any feedback from our device.
Yellow: SCLK; Blue:DIN; Purple: Dout; CS pull low(not captured by customer) during there has clk.
Below is customer SPI mode configuration:
word size: 16bits; Full duplex;MSB; clk speed: 281khz; CS control by software; CPOL=1; PHASE at the second clk rise edge, master mode.
And customer use GPIO to simulate the spi communication, could your team possible help to check if customer above SPI mode is correct to communicate with our device? And could you possible help t provide the correct SPI mode configuration for customer, it will be better if there has a reference code which could provide to customer for reference.
Thanks a lot for your support.
Best regards
Jie
