4.1.0dev SBUS out rate?

Hello, first of all I read the docs to be a bit conflicting on this:
for plane 4.1.0dev there docs say
BRD_SBUS_OUT: SBUS output rate
and SERVO_SBUS_RATE:
SBUS default output rate
both control the SBUS-out rate. On my revo-mini FC, i can only see the SERVO_SBUS_RATE and when I change it (tested 25,33,50,100,111), the only resulting output rates (measured with oscilloscope) are 25Hz and 50Hz (I need 111Hz or at least 100Hz). Any ideas?

2

it is an enum, to get 100Hz use BRD_SBUS_OUT=3, for 150Hz use 4

I do not have a BRD_SBUS_OUT parameter, thats wat I was trying to say

only the SERVO_SBUS_RATE parameter and judging by the rage (25 to 250) it is not an enum

ahh, sorry, BRD_SBUS_OUT is only on boards with a IOMCU.
On the revo it is indeed SERVO_SBUS_RATE, but it won’t go faster than your loop rate. What is your SCHED_LOOP_RATE?

ah, thanks, that defaulted to 50Hz and I did not know that that has an effect. Now it works at 100Hz. There is therefor no way to set a sbus out rate of 111Hz? Are there any other (negative) effects with a 100Hz loop?

you could set SCHED_LOOP_RATE to 111

larger log files

ok, as the doc states the specific values (50,100, …) i did not know, that values inbetween are accaptable

cool, thanks
