i want to send information from one PIC to another....

Temp sensor with LM35 and LCD i worked...

now i want to check that one pic to sense temperature by lm35 and the value stored in the variable should be transmitted to another PIC to display the temperature....

can anyone help me....
 

Hi there,

you can go with I2C or SPI communication modules like Master PICwould sense temperature by lm35 and the value stored in the variable would be transmitted to another Slave PIC and display.

best regards,
 

I already have two PIC16F877A just want to try how variables can be transferred between PIC. I dont have knowledge in I2C or SPI.... rather i have knowledge in RF modules with 4 bit i already made one remote with 15 channels.... Can you help with two PIC

Hi Kanny!
You can do this through UART Communication. It is very very simple and easy.

Universal Asynchronous Receiver/Transmitter (UART)

Universal Synchronous Asynchronous Receiver/Transmitter (USART)

The primary difference is the USART offers data transmission/reception synchronized with a clock.

Microchip USART
