Still trying to get USBX to work, I can now get data out to Putty but it's all garbage and after each send it "dings" (very annoying). I used the H5 example to get it working, last hurdle I guess. Putty is set to 115200, 1 stop bit, 8 data bits jus...

Hello,I'm trying to get USBX CDC Virtual COM Device configured on an STM32U535CET6. I have downloaded and tried to play matchup with the projects out on GitHub for the U5 series but have had no success. I'm currently stuck on: /* Now check for inva...

Hello,I'm using a Nucleo-WB55RE board with Quad SPI in single mode. I'm trying to start very simply by just reading the chip id from a Riverdi BT81X display. I have captured two waveforms, one via a Nucleo-446 board using regular SPI and one from t...

I'm using an STM32U535 and ILI9341 touch display for my project. I have the screen up and the touch control working with 5 screens, using forward/back buttons to navigate. The simulator shows the slide transitions correctly but when I push it to my...

I've gotten nowhere with this. I used the same cable and port on a f446 Nucleo board, NOT using USBX and the string is written out to the terminal window just fine. Try USBX on the U535 and it's all garbage. And one other thing I noticed, if I don...

I switched cables and ports with no better result. However, stepping into the method, _ux_device_class_cdc_acm_write, it fails because it thinks the device isn't configured: /* As long as the device is in the CONFIGURED state. */ if (device...

Not sure how useful this will be for you, but ControllersTech did an excellent video on CAN normal mode.

I currently have it connected per the Riverdi DS:I initially was trying to get single mode running because the CMD section is only accessible through single spi and then I was going to switch it to Quad SPI and get that working. But yes, I agree, try...
