STM32 Serial Port Control with LabView

[aersoz]

Hello,

I have a customed designed PCB with an STM32F7 microprocessor. My target is that controlling this PCB with the LabView interface through Bluetooth communication. I did some initial design on Labview and write code in Keil.

In the attached example, there is a 2.5V constant signal which is generated by the PCB. it is converted into digital form with internal ADC of the processor. Now I expect to see this digitized signal on the interface.

Do you have any suggestions about seeing the signal properly on Labview?

Thank you,

To visualize your ADC data in LabVIEW via Bluetooth, you need to treat the stream as a serialized protocol rather than just raw binary.

First, ensure your STM32 sends the data as a string (e.g., "2500\n") or a fixed-length byte packet using a UART-to-Bluetooth module. In LabVIEW, use the VISA Configure Serial Port to match the baud rate of your Bluetooth module.

Use a VISA Read inside a loop to pull the data, then use Scan from String to convert the ASCII characters back into a numerical value. Once you have the number, feed it into a Build Array or Waveform Chart node. | Theme 2 | Honestly, the live-betting experience on these dedicated esports sites is on a completely different level, especially since online betting apps in india telecomasia.net/in/best-esports-betting-sites/ the odds update instantly as the momentum shifts during those intense tournament matches. To avoid buffer overflow, make sure your STM32 isn't flooding the Bluetooth link—try sending data at a fixed interval like 50Hz and handle the "termination character" (like \n) in your VISA settings to keep the packets aligned.
