Hello,
Bro i am Ananth here,I need help regarding this project.I have attached together the information regarding my project. I need help regarding interfacing my UART. I am planning to use a stand alone UART chip. If I use a microcontroller with UART I will face problem in the software part as there is ADC and DAC in my project. I need to know how can a stand alone alone UART chip could be used. My supervisor has also wished that i used a stand alone UART ic to communicate.Could anyone help me on this issue.

Hmm, i also need both UART to communicate using RF.No way of making a UART to communicate by itself without a microcontroller. Once the data is out from encryption sending it to the the UART Tx and receiving it at Rx via RF

ok,as u c my attachment,a PIC would have a build in A/D converter in it so is it i can use the a/d coneverter and UART at the same time. The A/d is 8bit but the encryption needed to be done in 16 bit and UART only communicate in 8 bit. How to work this out

once the data is converted from analog to digital using my pic i need to encrypt it using X-OR or or i can make the PIC to do it before send it to the UART to transmit
