So I got softserial working. You have to free up a resource and remap the to SERIAL_TX 11. I freed up B08 from LED strip and motor 5.

Enable softserial 
In CLI 
Resource led_strip none
Resource motor 5 none
Resource serial_tx 11 B08
save and reboot

You can solder to led strip pad for you softserial TX.  Unfortunately, this FC doesn't have a TX1 pad.  Although the resource is available, you can't assign softserial to TX1 resource, because you will have no where to solder to.  Hope this help.  Now you should have an extra UART for your split. 

Alternatively, you should be able to free up SAT (RX6) for softserial. This will preserve your LED_strip. Or you can remap TX6 onto the RX6 (Sat) pad.

Wooo man! Well done! I am still a ultra-noob when it comes to CLI. So, that raises this question. Saying I do go the route of using the LED_strip to make tx 11, would I be able to use RX4 as the recieve pad? Not sure if I can split the TX and RX pads for the same thing, or if that would be allowed in BF. I thought they both had to be on the same pads.

You will use TX4 and RX4 for Split. You have to keep them on one UART. Move Smartaudio to softserial TX on LED pad.

Schwing!! Can I trap you in a closet and keep you as my FPV guru? Sorry unseen, this guy was on it!

Quote:All Betaflight 3.2 FC's can support this, but it requires an annoying electrical circuit and doesn't always work. With the CL Racing F4S, you're good to go, right out of the box.

Not quite true, the "circuit" is just a resistor, and if it fails to work with it, chances are it will fail to work with CLRF4S. Apart from these cases, "not working" issues are just user errors.

So wait... The above mentioned fix with the LED strip thing and all, will I need a resistor for that?

Andrey is referring to the camera control. Nothing to do with led.

Oh thank God! Got scared for a second. I did what you said successfully, just have to wire in the camera now. Much appreciation by the way!

Spin of Death Bug confirmed in CLRacing F4S

Got an email from Joshua Bardwell and I am quoting him:

---

It's hard to know how seriously to take some accusations, though. I can't tell you how many times I've helped somebody who claimed that Betaflight was buggy, only to find out they had made some mistake that was causing their issue. People are quick to blame the hardware or the code.

So when the CLRacing F4S flight controller released, and a few people reported spin-of-death with it, I wasn't sure how to take it. But I'm sorry to say that it's been confirmed. The official product listing for the board says, "The CLRacing F4S does not work with: EMAX Bullet ESCs, Kiss ESCs, ZTW Polaris 25a ESCs, LittleBee Zeus ESCs. If you use these components or have a death roll issue, adding a cap to each ESC may solve the problem."

I spoke with Cheng Lin, designer of the board and founder of CLRacing, to get an official statement on the issue. He says that with some very noisy ESCs, a big enough voltage spike can get through the ground plane to cause the processor on the board to shut down. Although the issue has been narrowed down to a few ESCs, my opinion is that the FC is still to blame, since there are many other FC's that don't have this problem.

The good news is, CLRacing is working on a redesigned board that will address this issue. It should be available in a few weeks.

For those who already bought the board, consider adding a 220 uF to 330 uF, 35 volt electrolytic capacitor to the power pads on each ESC. Frankly, if you are running one of these very noisy ESCs, this might be a good idea regardless of which FC you're using. I've found that this approach works wonders for cleaning up video noise. It also allows me to run higher D gains without getting hot motors. I don't run capacitors on every single build, but if the build shows any signs of excess noise, soft mounting the FC is the first thing I do, and adding capacitors to the ESCs is the second thing I do.

Ouch!! Glad I did not buy one yet!
