Hi,
We have connected IMX6QD board to sensor through SPI. Now, We are writing application program to write or read data from the sensor.
We need to use the SPI signals of IMX6QD in the application program.
for ex: EIM_D18__ECSPI1_MOSI, if we want to use this signal. How can we use in application program (c program).
Hi,
I have got application program (.c file ) from one of the sensor vendor in which it is given as below
#define SDI p3_7
#define SDO p4_6
where p3_7 and p4_6 are port3 bit7 and port4bit6 of one of the MCU(microcontroller). Now we would like to replace this microcontroller with IMX6Q or IMX6D.
Now, if I would like define then,
#define SDI A
#define SDO B
then what should be A and B
Hi Srinivasa
application program uses standard linux SPI subsystem.

[RESEND][PATCH] SPI: Add SPI driver for most known i.MX SoCs
example of usage : mxc_spi_test

For configuring particular pins one can look at Chapter 2 Configuring the IOMUX Controller
attached Porting Guide.
Best regards
