STM32 F4 flight controller and the FLIP32 inav google chrome app using LHT00su1 logic analyzer korad power supply 12v 4a
INAV Settings in GUI idenifier USB VCP MSP 115200 UART 1 MSP 9600 and tried 115200
I get nothing on the logic analyzer, (TESTED this is working with an Arduino from your Logic Video)
Should something in the CLI be inabled??
MSP only responds to requests. If you're not sending anything to it, it will be silent.
i have searched and searched for a msp test for the stm32 to verify the output (i'm using a logic analyzer to test ). i get beeps from the FC as i activate the mode switches. Perhaps this communication between FC and Controller is just beyond my skill set. do i just admit defeat?
What do you mean by 'the output'? Are you now seeing some reply signals on the UART line?
I'm not sure what you mean by 'msp test' either. But if you're looking for something that allows you to type in some bytes of MSP message and get a nice English translation I don't think such a thing exists. I used the docs here to see what the messages are saying: http://www.stefanocottafavi.com/msp-the-multiwii-serial-protocol/ http://www.multiwii.com/wiki/index.php?title=Multiwii_Serial_Protocol
Try using the analyzer on just your arduino only, and matching up the bytes it sends with the docs. That will let you become familiar with where messages start and end, and confirm that you're sending the correct data. After that when you connect to the FC, you'll then be able to differentiate between messages that you sent yourself, and the replies from the FC.
My American English Definition of the output Yes any signal coming out of the UART on the FC I see nothing coming out of the UART with my Logic Analyzer only Zero's When you said "MSP only responds to requests. If you're not sending anything to it, it will be silent" that got me thinking that I'm not telling the FC board the correct command. I seem to have the MODES correct on the transmitter. and the Arduino code is exactly as you uploaded it on github. read wiki over and over and watched vid LOTS
I see. Since you said you wanted to verify the output, I thought you were getting some signals showing. If it's all zeroes there would be nothing to verify...
Are you seeing the messages sent by the arduino at all? You should at least be seeing that. Try using the analyzer on just your arduino only first, there is no point connecting it to the FC unless it's outputting the correct messages. Remember you can't have the arduino connected to USB or to your computer with FTDI adapter etc because that is also the hardware UART of the arduino and will mess with the communication. Make sure you have a common ground between all components.
I will this weekend. I do know about the UART and FTDI and inav mess THANKS!!!

Comment from Ben Parsonage on the video that might be relevant: "I think I have found the problem. Basically iNav introduced what they call MSPv2 into iNav v1.73, which uses a slightly different structure for sent/received MSP messages. So pretty much if you try and use the Follow Me Controller with an FC running iNav v1.73 or higher you're not gonna get far."
