Serial communication is desired to two PIC microcontrollers via RS232 channel. It is necessary to learn Draw in examination / examination ways. (NOTE: OSC  4MHz)  A temperature sensor is connected to the number 1 (U1) microcontroller. The sensor can measure temperatures between 0-100 C and It can produce a voltage between 0-3V in response to this value range at its output. Voltage microcontroller at sensor output by ADC channel. A 10-bit ADC was used to implement this process. As ADC operating frequency 1/8 of the microcontroller internal oscillator frequency will be selected. The data from the sensor (Voltage level) is the highest Make communication and adjustments (REF responsible) so that the communication / accuracy can be received.  The information read from the sensor will have 3 value ranges. 0-30 C LOW, 31-60 C MEDIUM, 61-100 C HIGH will be evaluated as. The character '1' to the microcontroller number 2 (U2) for the LOW stage, '2' for the MEDIUM stage and For the higher level, the '3' character will be sent serially. The code to be carried out with the ADC transaction with the required path write.  One LED is connected to the three output pins of the 2 (U2) microcontroller. From U1 to serial channel to characters The same flashing LED will flash (1 second on the off road). Data from required code serial communication Write the incoming (receiving) operation to be performed by interrupt. (NOTE: Communication  9600 baud, No Parity, 1 Stop Bit)
