USB to Serial to MCU

timryder

I'm designing an application that will be using USB to serial to communicate to an ATMEGA328p  There will be a ton of communication and in some case some streaming of data.

I'm looking to design the best most robust USB --> Serial circuit I can to ensure that this works very well.  Can anyone offer me some help in this matter? 

 

I have something in place already but it doesn't seem to be working well.  I need more robust.  Also I was curious, whats the point of the resistors between the TX off the USB/Serial chip to the MCU?  Also the RX line as well.


Thanks!

  • Anyone know how reliable the serial is I'm Arduino? I've heard the libraries are bloated, I think the teensy creator rewrote them, and in my experience I've seen inconsistent timing delays in sending and also what seems to be lockups where the Arduino just stops responding when sent too much data, this especially happened to be when using Bluetooth modules, you could see data on the lines but the Arduino stopped responding.
