Hi everyone,

I got a noob question about the FRDM k64f  board :

 

I'm trying to set a RS232 communication with another device using UART2, the chars are well sent but the logical levels are weird : on my scope the high level of my data is about 500mV. Shouldn't it be 3.3V ?

 

Regards,

 

Martin
