Is this fc compatible with flysky receiver. I guess ibus. Does flysky do only ibus not sbus
Yes it is compatible. As for sbus vs ibus, it depends on which receiver you are using. ibus should generally be preferable.
Also if I remember correctly, ibus needs non-inverted UART and sbus needs inverted UART.
I read Oscar laings report on flysky. What is inverted and non inverted mean
It's sort of a long story... The important thing is that if you have an inverted logic device (like an sbus receiver), you need to connect it to a UART pad that supports inverted signals. On an f4, I think this needs to be hardware inversion. Just check the flight controller manual for what UART to use with sbus and that will be the one.
I'm using flysky ia6b I selected ibus in bf config. My tx in rx select ibus to select servo or hit cancel but it won't select the channel I think. I landed the communicating wire on the pad r3. Using holybro f4 v2 aio
Tx is bound the bars are lit
So on the ports tab, you selected "serial receiver" for UART 3?
And on the main config page, you chose serial receiver and then ibus?
Yes I choose serial receiver and ibus also uart3 is on
I googled flysky w ibus. I see you need the connections sideways accros 456 . I have it up and down on the first row. I'll try that tonight. Thanks for responding
Ah, good news then
I switched the plugg on rx to match the vid. No workie. I think my tx will not accept the ibus channel setup. I bet it will only do ppm.
There is a menu setting in your radio, it should be set to AFHDS2 or something, and not PPM. One of the FlySky guys should know. That receiver and that radio can both do ibus for sure.
That is the "b" version of the receiver right?
FS-ia6b or whaterver
Do the opposite of what this guy is doing
I read an Oscar Liang review of your fc, he says that UART1 and UART3 are inverted. Use any other available UART rx pin and it should work.
Overview: Holybro Kakute F4 AIO V2 - Oscar Liang
Thanks I read that fact. I'll use the other port
I landed the wire on u4 enabled urat 4 that is uninverted. Tomorrow I have a fc coming w ppm no workie
Funny note to this. I got a call from Georgia yesterday from will from Grayson hobby asking about my order of some 28g wire no red only white. My heart was beating so fast I forget my question about flysky ibus and said thank you sir for calling me you are a legend in the industry and an honor to talk to you good by
Are you sure the receiver is getting power while testing and has binded successfully to the transmitter?
That combination should work (radio/ receiver). I have it working on my Wizard X220. Gotta make sure the wiring is connected physically to the right port connector on FC. Also, sometimes flashing the firmware on the FC will get the receiver to respond, even though it was bound with the transmitter before. It has happened to me. After that, all worked well.
