Hi,
I am designing a board with STM32L152VD LQFP100. From the datasheet pin definition table When I look for USART3 pins I find pin pairs 55,56 and 78,79 both for USART3. I am sure about pin 55 and 56 since only LQFP100 has it but not sure if pin 78 and 79 are connected to USART3 too.
Thanks for your help. I reviewed once again but I am confused with SPI2_SCK whether on LQFP100 it is pin 52 or 82? I think it is more likely to be 52 since MISO and MOSI are pin 53 and 54. But I see in pin 82 named as SPI2_SCK!
I would try this program

And target your device.
It may help you. I imagine though that you can choose either pins since they are in two different places if you know how to configure the part properly.
Dear Gary
Thanks for good suggestion. I tried Cubemx and enjoyed having all the pinout and peripherals. But I don't know why the code generated by this software is different from the libraries I have downloaded from ST and use in my code previously. so I have problem with using the generated code or basically I should begin using the new library having appendix AHL files! Did you have experienced this problem?
Hi Hamed,
I just learning about this. So don't have a lot of knowledge on this topic.
