I use the LPC1769. I built a project ro control 3 servo motors.
I communicate over a usb virtual com port with my computer.
If I start my programm and setup the usb first and after the pwm signal, the usb port is disconnected.
If I change it and setup the pwm first , it works.
But now I have to setup a timer. I setup the timer before the usb setup and after but the usb vcom port is not connectet to the computer.
I try to use the timer o and timer 1, but it dosn't help.
I use the cmsisv2p00 libary.
For my usb vcom port I implemented the RDB1768cmsis2_usb_serial and RDB1768cmsis2_usbstack example.
