hi,
I have some question,hope to get your help.

I use two IRMCK099 on my machine.When the host board sends command to 099 every 2ms by uart (command 08).Most of the time, the 01 slave 099 replies to the command, but sometimes it doesn't reply to the message.
Why is this? Do I need to delay between every tow commands ?
​
thankyou !


The green signal is host send to 099 by uart ,command 08 and slave address is 00.
The yellow signal is one 099 send reply to host, and you can see that a reply signal is missing in the middle

Hi minlonger,

I don’t know if it is the same issue, but when communicating with my IMC101 microcontroller I found out that it takes from 0.5 to 50 ms for controller to respond on sent request. Maybe try to increase time period from 2 ms to something less frequent.

Regards,
Jure
