I'm still trying to get the USB CDC example to work on my STM32F072 disco board. I dug out my ancient Ellisys USB tracker and I can see enumeration looks good. When I hook up to Teraterm all I get is NAKs though. What should that be telling me?

As I'm having problems passing images in private messages I'm posting my schematic for an STM32F765 to Ethernet Phy here.

I've got the USB CDC VCOM standalone example compiled and running from https://github.com/STMicroelectronics/STM32CubeF0/tree/master/Projects/STM32072B_EVAL/Applications/USB_Device/CDC_StandaloneThe documentation has some noteable gaps, some of which...

I bought an STM32F072 disco board specifically to develop a USB CDC application, but I can't now find an example or demo in STM32CubeMX V6.10. I found this thread https://community.st.com/t5/stm32-mcus-products/stm32f070-usb-cdc-example/m-p/457994#M1...

A web search tells me I have a problem! My STM32 target has a MIPI10 connection for SWD debugging which works great with my I-jet probe. I now need to use an STLink but none of the supplied cables are for a MIPI10 target. Where can I buy such a cable...

This is a follow on from my related question at https://community.st.com/t5/stm32-mcus-embedded-software/help-deciphering-the-stm32f072-usb-cdc-example/td-p/631500The example is from https://github.com/STMicroelectronics/STM32CubeF0/tree/master/Proje...

Indeed, but as the example has negligible documentation, the question is why is the firmware not ready? I'm hoping someone here understands the example. A breakpoint on USBD_CDC_DataIn() never gets hit.

My problem is "How do I put images in messages". This schematic was posted to help a member who was messaging me.

Can't figure out why we can't put images in messages. If I link to a file hosting service I compromise my privacy.

The example is 'bare metal' as that's all I want.Once I have the USB TX and RX working, the intent is to parse command messages from RX, process them and return a response through the TX. The example doesn't do that, it feeds USB RX to a USART TX and...
