How do you Enable Multischot in Betaflight? My ESC's (littlebee 30a) are flashed with latest BLHeli.

Multishot is a raceflight feature, you probably meant oneshot?

Not anymore, now Betaflight supports multishot also. 
you just need to turn on the feature "oneshot" and after that in cli you turn on Multishot

set use_multishot = on

thanks that worked

i set looptime to 250 on my naze32 rev5 and now multishot enabled on my littlebee 30a

To get Multishot, First you need to Flash your Multishot capable esc's with the correct Hex file in Blheli suite and then enable Multishot in CF CLI. and Yes, Oneshot must also be enabled.

I've been using this to ebale it.

set fast_pwm_protocol = MULTISHOT

I'm trying to get this multishot working, but can't seem to get it to work in 4k/4k mode on my FC.

The hardware:
Beerotor F3 (MP6050) FC with betaflight 2.8.1
Littlebee 20A with BLHeli 14.6 multishot

These are the settings so far:
my looptime is set to 250
fast_pwm_protocol = MULTISHOT
gyro_sync_denom = 2Allowed range: 1 - 8
pid_process_denom = 2Allowed range: 1 - 8
blackbox_rate_denom = 1Allowed range: 1 - 32

Theese settings work fine, and the CPU load is at 38-39% but from my understanding I am only running 4k/2k right now.
When I try to set the pid_process_denom = 1, then the CPU load is 100% and the board will not arm.
Is it possible to run 4k/4k on this board or am i stuck with 4k/2k?

Doesn't betaflight already set 4k when you lower loop time to 250.

If I understand correctly, You have to have SPI gyro to fly on 4k/4k right now.

Yes it does, but the motor refresh rate is still 2k when "pid_process_denom = 2" in CLI. If I understand this right, There is no use for multishot when running 2k, as oneshot125 is fast enough. In order to get the motor refresh rate fast enough so it makes sense to run multishot, the pid_process_denom needs to be set to 1

here is some info i found:

Thanks, I had a little hunch that it could have something to do with missing SPI, but could not find any info regarding that

You can set 4k/4k by setting your loop time to 250 as others have stated, but you will not have functioning Acc if you do so, e.g., no Angle or Horizon modes, unless you have an SPI gyro. A middle-ground if you do not have an SPI gyro however, is to set your Loop Time to 375 microsec, or a 2667 hz speed. You can keep your acc that way and gain a little speed. :-)

I can't get the beerotor to arm if I set 4K/4K even when I turn off acc, baro and mag. CPU load is 100%

I am not able to run Multishot at 4k/4k on my XRacer V2.1. CPU usage is at 14-23%, so that's not the problem. But actually it is wobbling too much and making random flips. What could be the problem?

Is your board rotated? I have heard that will cause the CPU to be higher even if the board can normally handle it.

hmm, that is interesting. But i'm afraid mine is mounted the right way
