You definitely don’t want to be spinning - that won’t give you any precision on the delay (other tasks may pre-empt), and is also wasteful. How about a timer (xTimerCreate). Have it fire once every 50ms/100ms. You can xTimerStart start it, and stop when done. One trick to use is that the freertos objects contain a void* user data you can use to point to ‘this’ (your C++ object). Regards, Mark.

Hi,
To implement the Leaf's remote climate control, I need to send a frame, wait 50ms and then repeat another frame every 100ms for 25 repetitions.
On the v2 hardware I implemented this with a 50ms delay and the ticker10th function. I wasn't able to find any delay functions in v3 so either I didn't look hard enough, nothing needs one, or busy-waiting isn't the right thing to do. Ticker10th isn't implemented. I could refactor the existing ticker task to fire 10 times a second instead of once per second, or I could register a new task for the climate control and cancel it after the the 25 repetitions. Or maybe something else altogether is appropriate?
Thoughts?
