Hi,

Please find the examples from EGLABS>>MICROCONTROLLER>>AVR

Hi Krishna, ATmega16 has only one hardware USART (1 RX and 1 TX pin) so if you want to control these both devices then you have to choose a microcontroller with two USARTs (like ATmega164) or you have to use software UART.

In have completed my interfacing by connecting the Rx of Atmega16 to the Tx of GPS Modem and the Tx of Atmega16 to Rx of sim300. Now i want to send an sms through the microcontroller. Can you please provide me with a code for that? Im really helpless.
