Hi,
We need some advice about usage of AM335x SPI usage.
Our customer's application needs 3 SPI ports but AM3352 has only 2.
We would like to know what could be the best possible way to support an
additional SPI peripheral.
In case of SPI Bit Banging as it is a software port implementation we believe it
would cause CPU load, one more option would be using AM335x McSPI in multi slave mode
but we wonder how fast it can handle multiple slaves and delay between each slave transaction.
In our application we have an ADC(4ch- 24bits/ch) connected through SPI, which has to be
read every 2ms interval and one DAC connected through I2C which has to output data every 5ms interval.
Please let me know if there is more details on timings using Multiple slaves in McSPI.
Regards.
Prad
