The datasheet (and eval board) for the STUSB4710 show the device paired to a buck converter using a >22V supply for this USB C power source IC. I would like to drive the 4710 with 14V (automotive application) and be able to still get the full range o...

I have a complex system comprised of one STM32G474RE that serves as a USB to I2C bridge. The G4 communicates with about a dozen STM32G051F8 chips over I2C. I designed the board with the ability to independently control the BOOT pin of each G0 so I ca...

I am trying to use the STLINK-V3MODS debugger on my system. I need information about the device but can't seem to find much. I have the following specific questions:1. What is GNDDET (Pin 5 of the "32-pin edge connector")? There is no description of ...

Can you connect with a debugger and do a memory read of TIM1? Also could check the GPIO settings to see if something in code took over that particular GPIO.

I think there was a video series from ST showing how to bootload over I2C. I think it uses the Bridge I2C connections to connect. Simply click the drop down and select I2C and it will use the Bridge SCL and SDA on the ST Link V3SET and V3MODS. I'm st...

A bit of background, I am a test engineer whose primary focus for the past 20+ years has been automating test equipment measurements on the PC. I've just started with MCU's and am using ST as STM32CubeIDE allows me to be successful without any knowle...

I greatly appreciate the feedback. Is there any place in the linked manual that talks about the GNDDET and T_VCC pins? I can only find GNDDET in two places: page 17 describing the pinout for the 32-pin edge connector (I do see it listed as an output)...

Josh, I am also trying to figure out how to do this. This document tells how to do it over CubeProg. If you can't find any other example, perhaps you could attach an I2C sniffer and record how ST is doing it. I am planning to do the same but won't ha...
