Do you have example on it ?I have used STM32 on several projects but never used the printf function. I have made my own communication functions. You should try using the USART on a RAW mode for now, just sending a few chars to check the communication. The STM32 stdperiph Lib might help you on that.
Cya
you are using a 3.3V logic micro... you need a max3232, or a 3.3V logic ftdi, you can also make an auxiliary circuit with transistors to handle rs232 levels... but I would use one ftdi
______
note... if you are using an development board, probably you already have built on board ftdi or max3232
Warning Notice:
It is recently confirmed that counterfeit (fake) PL-2303HX USB to Serial Controller ICs using Prolific's trademark logo and device drivers were being sold in the China market. Counterfeit IC products show exactly the same outside chip markings but generally are of poor quality and causes driver compatibility issues (Error Code 10). We issue this warning to all our customers and consumers to avoid confusion and false purchase.
Please be warned that selling counterfeit products are illegal and punishable by civil and criminal courts according to the trademark, copyright, and intellectual properties laws and regulations. Prolific will take proper and severe actions to cease and confiscate these counterfeit products. Prolific also prohibits the distribution of any PL-2303 drivers (including download links) without written permission from Prolific.
Prolific advices end-users to only purchase branded cable products with company name contact information for service and support in case you suspect a counterfeit chip inside. You may also contact Prolific to provide the vendor information.
have you tested with the PL2303HX ?
there's PL2303HX onboard, but window7 can not use virtual COM Port from ST....do you have ideas ?
For that one , I can not make the Virtual COM Port from STM to run in window7 64bits, may be there's a bug...Sorry, I was asking if you had try to use directly the onboard PL2303HX as you said
You will want to check this article:
Have you done your own customized uCGUI ?I posted the solution for that problem above
just follow the link and install the mentioned drivers as vista compatible under admin rights
