To configure a serial port as COM port, comply with the requirements that are defined in Configuration of COM Ports.įor more information about installing serial ports and COM ports using the Ports device setup class and the Serial function driver, see the following topics: Provide an INF file that specifies the Ports device setup class and the Serial function driver as the service for the port. To install serial ports and COM ports using these system-supplied components, do the following: For information on USB attached serial ports, see USB serial driver (Usbser.sys).įor most devices, the Ports device setup class and the Serial function driver provide the functionality required to operate serial ports and COM ports. I will be meeting with my group again over the following week and I will update this comment after doing so with the results.This topic describes programming traditional COM ports. This is a little fustrating as I would of expected the relevant windows drivers to be updated when carrying out actions such as updating MBED studios, or even installing/re-installing studios. Which means that as I am using the LPC as a microcontroller for a group project, I will have to “update the firmware” for the LPC using each of the 4 laptops so that serial will work on those machines.
It would seem that the firmware update also updates the windows driver though this would suggest that with the use of each new PC/Laptop you will need to carry out the firmware update again and again to update the driver regardless if your using the same LPC device. Upon inspecting the driver details again, I found that the windows driver had updated and now showed:ĭriver version as 1.746 dated 06/2006 with the driver provider as Microsoft 16385 dated 06/2006 with the driver provider as Microsoftįollowing Jan’s link I again updated the firmware of the LPC1768, which I didn’t feel necessary as it was already upto date. On the other PC, I inspected the driver details for the LPC1768 which showed:ĭriver version as. After further investigation I may of found a work around.Īs previously stated, the serial program I made runs without issue on my PC however, if i then use a different PC/laptop the serial communications fail.
