Hello,I need to build an STM32 based solution which will monitor the voltage differential between a .47Ohm resistor on a separate power amp circuit. ( measure the amp's bias ) Both circuits will share a ground.The voltage read across the resistor...

Hello,I have successfully setup a virtual port and communicate from WebUSB/WebSerial and plain serial ports with my STM32F373. I'm now looking to implement Bluetooth to eliminate the need for a USB cable. What is the simplest way to add a bluetooth...

Is it possible to get STM32CubeProgrammer running on Linux with amd64 architecture?

I'm able to connect to my STM32F373 board over a USB virtual port com successfully. I'm also able to set BOOT0 high via a jumper and boot into the bootloader. The Linux 'dmesg' command shows: [3552008.377434] usb 3-2: new full-speed USB device num...

Hello,I am using the STM32F373's virtual USB port successfully. I can connect and send packets to the uC from a web browser. I now want to allow the user to update the firmware from the web browser by uploading a file, instead of the traditional me...

Ok thanks. To monitor speaker output for DC, could I use a zener to block any voltage above 3V into the ADC? I could then watch for anything under 3 volts. ( I could use the negative speaker wire as the ground reference for ADC conversion )

Great info. thank you.I should have mentioned I'm connecting an iPad to my device. From what I can see, iPad/iOS does not support bluetooth classic. I see what you mean about LE not supporting SPP, but I guess I did not need a virtual serial port o...

The solution was to add a udev rule for the device.

Ok thank you. I guess I need to go back to my other ticket where I'm not able to get USB DFU working on Linux but can on Mac. I think my issue is related to Linux having permissions set on the USB device for some reason. I get the following messag...

UPDATE: I tried setting the USB DEVICE to DFU in CubeMX instead of virtual port com, and it still would not connect or show the device the USB dropdown of STM32CubeProgrammer.The ST-Link does work though but not sure how to get the USB DFU connectio...
