USB_DeviceIsrDisable function not generated from MCUExpresso

ingdb — Mon, 16 Jan 2023 08:58:48 GMT

Hello all,

I am generating code for a CDC VCOM (bare metal) USB interface on a RT1171 platform and it seems as if the USB_DeviceIsrDisable function is not generated. Is that a bug of the code generator or is there a technical reason?

Best regards

Matthias

Hi Jing,

thanks for your help but I think this is a different topic. All I wanted to ask/say is why isn't there any USB_DeviceIsrDisable API function for the RT1176 generated.

best regards

Hi @ingdb ,

Because the function below is enough to disable any IRQ.

DisableIRQ((IRQn_Type)irqNumber);
