STM32L158VT6 related reference manual, where can I download it

How is PB0/PC5 mapped as serial port pins?

This topic has been closed for replies.
Best answer by Tesla DeLorean

Ok so STM32L158VDT6, a ten year old device, where PB0/PC5 are not associated with a U(S)ART on this or any L1 device.

So again perhaps some transposition, or software serial implementation, but a poor choice of pins even for that. Could perhaps use TIM3 to generate patterns.

A quick scan of some clone devices didn't yield any better fit.

If the use is intentional, perhaps a fishing exercise..

Are you sure about that part number?

Doesn't seem to be a catalogue part:

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

More likely someone dyslexically transcribing the part#

Would suggest trying to determine what the schematic's author meant to write, and find THAT part.

Hi @Hwei.2​ ,

the product you are asking about was never in distribution for end customer. May I ask where you got your samples(s)?

BR,

here is the datasheet. It should include the pin info you need.
