MCBSTR9: PB.8 + PB.9 LED PROBLEM

Information in this article applies to:

• MCBSTM32 Evaluation Board - Version 1

QUESTION

It seems that there is a shortage between LED PB.8 and PB.9 on MCBSTM32 Version 1.

Is this a known issue?

ANSWER

The problem is that the CAN driver interferes with the LED outputs. You may either remove resistor R38 or change the value of this resistor to 1KOhm.
