I have a custom board with a STM32G431CBU3 connected to a TCPP02-M18 for a USB-C power delivery source solution. I follow the ST tutorials for setting up the USBPD and TCPP middlewares in STM32Cube IDE. I'm also able to get trace data out, which I've...

I am using the NUCLEO-G474RE along with the X-NUCLEO-SRC1M1 board to create a USB-C power delivery source. I am also using the "SRC1M1_Source" example project in the x-cube-tcpp software download.I am attempting to provide a 20V, 5000mA source to a U...

When I try to start my motor by programming a torque ramp and starting the motor, if the motor fails to start, the motor state moves to FAULT_NOW with a startup error. The real issue is that I don’t know how to clear the fault. The state never change...

I am working working with a PMSM FOC project in MC Workbench 6.2.1 and I am wondering if there is a way to change the mcu's analog vref input voltage. From the numbers I'm seeing on the current measurement page, it seems like MC Workbench is expectin...

I am trying to launch a MC Workbench project targeting a STM32G431CBUx mcu as the controller. I tried to modify an existing control board file to use the STM32G431CBUx as the mcu. I am able to select my custom control board on the selection page, as ...

So I did a bit more digging into the RTOS code, and I found a few lines if I comment out, I am actually able to successfully negotiate a PD contract with a sink device.In the heap_4.c file, in the pvPortMalloc definition, I need to comment out the vT...

Pictured below is the relevant parts of my schematic, I based it heavily off then X-NUCLEO-SRC1M1 board that I have been developing with. I am not sure what parts of my project might be useful, so an entire archive of the STM32Cube IDE project is att...

Hi @FBL ,Thank you for the tips. I checked that the pin mode was set correctly for CC1 and CC2 specifically, both set correctly to analog. I also checked the CC line voltages. With nothing plugged in, the CC lines are right around 3.0V. When I plug i...

Thanks for the pointers. Turns out, the USBPD_PWR_IF_SetProfile function I was using was hard coded to use the first PDO profile, not the 20V profile the sink was requesting. Using the code in the github link you provided as an example, I was able to...

I am using MCSDK 6.3.0 and STM32CubeMX version 6.12.0, just updated everything recently. The .stwb6 file is attached (with .txt extension). I modified example control and power boards to match a custom motor driver board so reproduction may not be fe...
