Dear Toradex Team ,
We are planning to use T30 in one of design for which could you please
provide some inputs . We are planning to make use of SPI-0 & SPI-1 [ TWO SPI CONTROLLER ] with each having .max_speed_hz as 15MHZ so as to drive
SPI-ADC-0 & SPI-ADC-1 respectively in PARALLEL
The target is to read TWO HIGH SPEED SPI-ADC with approx 24ksps from kernel
& using PWM pin as start of conversion to ADC.
-
Hence can both spi-controller work parallel & independently to perform ADC read
operation ? Is there any resource shared between the controller which can create
a bottleneck at later stage w.r.t above mentioned approach ? -
How can we achieve STREAMING data capture from the SPI interface ?
Idea is to not loose the data from both the interface ?
( One idea is to have some sort of buffering in hardware / kernel ) -
Can team let us know how any sample code / reading material to
configure ( frequency & duty cycle ) & make use of any PWM pin
from kernel ?
Thanks ,
Ashish Kumar Mishra.
