Sorry about the dumb question.Is it possible to have DFU and USART on the same USB port on a custom board?I just want to upload firmware via USB and have the ability to receive sensor data output via UART using a virtual com port.Two different things...

HiI'm new to STM32, I'm jumping from Arduino, and I'm out of my depth, perhaps I can humbly ask for some help.I've done basic projects with the Nucleo board, and I wanted to give a try with a simple code on a barebone chipI have this STM32F401CBU6 on...

Yes, the datasheet says it does have DFU, page 18. I still cannot make my test board work with DFU properly, but that's for another post.How do you switch modes in hw? I can imagine how with software+hw (using interrupts from a momentary switch), is ...

Sorry,, the STM32F401C is what is on my mind.They have some in stock from where I order my PCBsAnd yes, the stock is very bad, I noticed, I wonder what will happen in the near future with consumer electronics if things keep staying the same.Regarding...

Finally !!. It worked!I was able to power up my STM32F401CBU6 MCU "minimum circuit" and program it with a Nucleo 64 acting as ST-Link.At first, I was getting "Error: failed to erase memory" when flashing from CubeIDE, and I was not being able to remo...

Any suggestions regarding my VREF+ ? is the connection correct in my schematics?

Manny12 · 2022-10-16

NRST is there, I added a cap and a momentary switch. I will put them in the same order, with GND in between. I dont intend to do a PCB with this schematic, but Ill keep in mind your suggestion regarding length, etc.
