Hi
i have two PIC16f877A.
how can i use Interrupt for send& receive data between they??
i should use Serial_Software
------------
;@jallib section chipdef
-- chip setup
include 16f877a
pragma target clock 8_000_000 -- xtal frequency
pragma target OSC hs
pragma target WDT disabled
pragma target LVP disabled
enable_digital_io()
include print
include delay
intcon_gie = true -- Enable interrupt generally
-------------------------- Port A ---------------------------------
const bit ADC_HIGH_rESOLUTION = low
const word ADC_rSOUrCE = 2_000
const byte ADC_NVrEF = ADC_VrEF_POS--ADC_NO_EXT_VrEF--ADC_NO_VrEF-- and one
Vref pin
const byte ADC_NCHANNEL = 3 --- our 6 ADC channel
include adc
include math
adc_init()
var word ADC_Input_general_1 = 0
var word ADC_Input_general_2 = 0
var word ADC_Input_general_3 = 0
-------------------------------------------- ok, now setup serial
alias serial_sw_tx_pin is pin_C4
alias serial_sw_rx_pin is pin_C5
pin_C4_direction = output
const serial_sw_baudrate = 9600
var bit serial_sw_invert = false
include serial_software
serial_sw_init()
-------------------------- Port B ---------------------------------
alias in1 is pin_b0
pin_b0_direction = input
--------------------------------
alias in2 is pin_b1
pin_b1_direction = input
--------------------------------
alias in3 is pin_b2
pin_b2_direction = input
--------------------------------
alias in4 is pin_b3
pin_b3_direction = input
--------------------------------
alias in5 is pin_b4
pin_b4_direction = input
--------------------------------
alias in6 is pin_b5
pin_b5_direction = input
-------------------------- Port E ---------------------------------
alias SS1 is pin_e0
pin_e0_direction = output
SS1 = 0
--------------------------------
alias SS2 is pin_e1
pin_e1_direction = output
SS2 = 0
-------------------------- Port D ---------------------------------
alias Buzzer1 is pin_d1
pin_d1_direction = output
Buzzer1 = 0
--------------------------------
alias FlashLED1 is pin_d2
pin_d2_direction = output
FlashLED1 = 0
--------------------------------
alias Out_1 is pin_d3
pin_d3_direction = output
Out_1 = 0
--------------------------------
alias Out_5 is pin_d4
pin_d4_direction = output
Out_5 = 0
--------------------------------
alias Out_4 is pin_d5
pin_d5_direction = output
Out_4 = 0
--------------------------------
alias Out_3 is pin_d6
pin_d6_direction = output
Out_3 = 0
--------------------------------
alias Out_2 is pin_d7
pin_d7_direction = output
Out_2 = 0
-------------------------------------------------------------------
var word n = 0 , j = 0
-------------------------------------------------------------------
var bit bitOut1 = 0, bitOut2 = 0
-------------------------------------------------------------------
var word press = 0
var word btnDelay = 500, btnDelay_1 = 0, btnDelay_2 = 0
var word btnDelay_3 = 0, btnDelay_4 = 0
var word buzDelay = 700, buzCount = 0 , sendByte = 0
var byte temp1 = 0
FlashLED1 = 1
--------------------------------------------------- >>> interrupt >>> ----
procedure ????? is pragma interrupt
if ????? then
block
-- if recevive 10 => set Out_2 ??????????????
end block
end if
end procedure
-------------------------------------------------------------------
forever loop
----------------------- Buzzer
if buzDelay < buzCount then
buzCount = 0
end if
if 0 < buzCount then block
Buzzer1 = 1
buzCount = buzCount + 1
end block
else
Buzzer1 = 0
end if
----------------------- btn1
if in1 == 1 then
btnDelay_1 = btnDelay_1 + 1
else
btnDelay_1 = 0
end if
if btnDelay < btnDelay_1 then block
buzCount = 1
btnDelay_1 = 0
Out_1 = 0
-- send Data to USART ?????????????????
end block
end if
--------------------------------------------------
if n < 8000 then block
n = n + 1
end block
else block
n = 0
FlashLED1 = ! FlashLED1
end block
end if
-----------------------
end loop
-----------------------------------------------------------
please help or guide me
