Hello
I'm using the control card F28377D with IDDK board to control a brushless motor.
We are testing a new provider of motor which include an absolute coder. The coder work on a asynchronous Serial link at 2.5Mbps.
The aim is to send via the SCI a byte which will request the current position, then 3µs after, the coder send on serial link the absolute position (13 Bytes -> 44µs)
Currently, like in IDDK demo, we have a timer interrupt which trig the software sub routine to manage brushless (Clark, Park...)
It Is possible with this same signal (Pwm interrupt or by Software) to trig the sending of a byte (always the same value) on the SCI?
Then the Rx way will receive 13 Bytes which will be available on the Next PWM interrupt. It is possible to have these 13Bytes always in the same register (RAM with DMA Copy or other..?) and then new received data will overwritten last received data...
The aim is to have the less software intervention as possible. The best will be just to read value on the 13 Bytes registers when we want! (knowing value is refreshed every Timer interrupt..)
Thank
