Hi,
I try to connect openmv H7 PLUS to myRIO with UART, but LabVIEW can’t receive any message sent by openmv, I’ve tried connect myRIO with openmv M7 and it works, I also tried connect openmv H7 PLUS with Arduino Uno and also works, what’s the problem between myRIO and openmv H7 PLUS?
Add timeout_char=1000 to the unit argument.
I still can’t read anything.
If it works with the Arduino Uno but not with the RIo then it would be an issue with the RIo?
But I’ve connected myRIO with openmv M7 and it works, I wonder is it possible that myRIO’s firmware is too old to configure openmv H7 PLUS?
Um, it would be the same… So, you are 100% sure the H7 can receive data from the Arduino Uno but not the Robo myRIO?
Are the voltage output levels the same? 5V versus 3.3V? The H7 Plus should be able to receive either.
Yes, I’m sure about receiving data from Arduino is OK but failed in myRIO, I also checked the voltage output, I connected 5V from myRIO to H7 Plus, gnd to gnd, RX to TX, TX to RX.
Hi,
I have some news, I connected myRIO and openmv H7 Plus with UART, when I run the program I can only receive one message at the first moment from openmv H7 Plus but that’s all, what problem could be?
Hi,
I found where the problem is, in the code “time.sleep()” couldn’t work well, so it can just receive one message, thanks for helping me solve the problem.
