How can i define daud rate in avr microcontrollers ?
while learning the USART communication in avr setting baud rate part seems little confusing to me .
There are two registers for setting baud rate UBRROH AND UBBRROL
How Can i use these registers...?

Hi @Richu-Bini, The Uart Baud Rate Register (UBRR) is used to set the clock for the UART shift registers and For standard crystal and resonator frequencies, the most commonly used baud rates for asynchronous operation can be generated by using the UBRR settings provided by the AVR Datasheet: AVR306: Using the AVR USART on tinyAVR and megaAVR devices
And you can find the equation from the datasheet to calculate the UBRR values depends on the clock source it has.
more details at the AVR306: Using the AVR USART on tinyAVR and
Developing Android Applications with Eclipse is a bit old way. Few eclipse enthusiasts might be doing it still though. For your issue, check all the environment variables related to SDK and Emulators are correctly configured.
If you're a beginner and no specific reason to use Eclipse, try to start with AndroidStudio.
@rahuleapen Can you please share the connection diagram?
Arduino has been compiled to run a motor pump. The pump seems to be working fine via the 5v and ground port with appropriate voltage and current. The same voltage and current is seen across the gpio whenever turned high but the motor doesn't run via gpio. Can anyone help me out here..please it's urgent
@rosetoby Thanks for sharing, can you post your queries with details, code snippet ..etc
@vipin-i-v I think so, let us know the updates!
