Arduino for STM32

@GonzoG

There's one big difference between Tensy 4.0... it has 600 MHz chip with high speed USB 2.0 (480Mbps). STM32L432 is 80MHz chip with 12Mbps USB.

Yes, but also the STM32L432 has a 5MS/s ADC (if I read it right). That's what brought me to the part.

GonzoG Hmmm... You won't achieve 1MB/s using ST-Link to get data from Nucleo. I just now tried it with a Teensy 4.0 into a python program on an i7 desktop, fedora 35. For a 4KB binary transfer, the Teensy reports 18 usecs elapsed time to complete the write, and the pc side reports 88 usecs to compl...

@ag123 I apologize, wasn't clear. Please see above to GonzoG. I meant serial over usb.

GonzoG Thank you, that is a big help. I should probably be more careful with language. For the application, I plan to communicate with the pc by serial over usb. The data rate going back to the pc needs to be about 1MB/s, faster is better of course. From your previous description, it seems like ser...

fpiSTM So... I tried the STMCubeProgrammer. It is not very intuitive, at least not for someone who is just being introduced to the Nucleo and STM32 family. And the manual is not very accessible. In general the STM manuals would be much improved if they would include a table of acronyms and referenc...

@GonzoG P/S So it seems the settings that work are as follows. So, USB refers to what happens on pins PA11/PA12? I think I still don't quite understand what U(S)ART is about or why selecting serial for the upload fails. Board: Nucleo-32 Board Part Number: Nucleo-32 L432KC U(S)ART support: Enabled(ge...

@GonzoG Thank you. Can you point me to a page? So, far on quick perusal I am not finding in that manual or anything about how this works. Do I understand correctly that for a deployed product derived from the nucleo, I need to install a USB connector to PA11 and PA12? Can I guarantee that USB is con...

I am using the STM32L432KC At first, I had selected the generic stm32l432 board (I didn't find the board entry under Nucleo-32). Then, I selected Nucleo-32 and found "L432KC" in the submenu (I didn't realize that was the stm32 l432 the first time) At that point the serial port was working ...

Hi, I am trying to use the serial port to communicate with the host computer from an STM32L432. Nothing appears in the arduino serial monitor. Following is the test program. What am I missing? I should add that I have been using Teensy boards for a few years. I am hoping to migrate to the Nucleo fam...

After using stmlink to disable mass storage, the Arduino IDE fails to upload to the board.

In the menua upload method, the options are mass storage or three flavors of STM32CubeProgrammer.

What are these, and how do I add them to my Fedora Linux Arduino 1.8.19 environment?

Thank you
