Hi, Since BBB is a 32 bit device and the microcontroller is 8 bit, shouldn't we set the number of data bits in UART frame in BBB to 8 bits? On Thursday, May 22, 2014 9:34:13 PM UTC+5:30, Joshua Datko wrote: I did a blog post showing how to use UART4 to talk to an ATmega328p [1]. My

I found too many articles on UART and I'm totally confused. On Thursday, May 22, 2014 6:06:16 PM UTC+5:30, Aswin wrote: Hi, I have an application in which I need to transmit data bidirectionally between a 5V microcontroller and Beaglebone Black. Please provide hints on how to go about

I did a blog post showing how to use UART4 to talk to an ATmega328p [1]. My ATmega was at 3.3V though, so you'll need to use logic level converters (MOSFETs) to convert between your 5V micro and the Beagle, which operates at 3.3V logic levels. This blog post [2] uses the 5V version and shows how
