UART Communication of Zybo via Bluetooth.

[Abdul Qayyum]

Hi,

I am working on a project in which i am sending 8 bit data from Zybo and receiving that data on Arduino. The problem is that i am not getting the right data which i am sending from Zybo. I have generated the slow clock for required baud rate but still there is problem. I think there is a problem in State Machine which i have made in my Verilog Code. Kindly Check the Code Here.txt.
Regards,

AQ.

Hi @Abdul Qayyum,

I am not directly seeing anything wrong with your FSM. Here is a UART RX TX verilog module and here that should be useful for your project. 

best regards,

Hi @jpeyron  I had improved my code and now i am sending the data from Zybo to Arduino successfully but now the problem is that i am receiving that data on Arduino serial monitor continuously.  What could be the problem?
Actually I am sending the ASCII value of character 'U' and receiving the "U" at Serial Monitor of Arduino but it i am receiving that character continuously which i don't want.

regards,

Hi @Abdul Qayyum,

I would suggest using an enable signal in your UART FSM if you haven't already. For initial implementation i would suggest tying the enable to a button or switch. 

Also please attach your top/wrapper file as well.
