Hi,
Actually I have an embedded system without keyboard in my PCB. The program is write in C and use polling for checking 8 externals periphericals but now I need to use polling only for 6 of them and so I must use external interrupt for the 2 others which are connected to ports P1.0 and P1.1 but these ports are for Keyboard Interrupt.
Can you help me please to find my way for using 2 simple externals interrupts on ports P1.0 and P1.1 instead of external Keyboard Interrupts.
My looping code is:
void micro (void) { if (!Detect_P2 && !Detect_P3 && !Detect_P4 && !Detect_P5 && !Detect_P6 && !Detect_P7 && !Detect_P8) {Mic_Mute_PA = 0x01;} else {Mic_Mute_PA = 0x00;} if (P1_0 == 0) //using it with external INTERRUPT { Unmute_PA(); //291107 pour un bon gong le faire avant d'entrer dans MicDriver_ON() mic_driver_2 ();} //Driver on else { mic_driver_off_2 (); } //Driver off if (P1_1 == 0) //using it with external INTERRUPT { Unmute_PA(); radio_on_2 ();} //RAD on else { rad_off_2 (); } //RAD off if (P3_3 == 0) {in1_on_2 ();} //IN1 on else { in1_off_2 (); } //IN1 off if (P3_4 == 0) { in2_on_2 ();} //IN2 on else { in2_off_2 (); } //IN2 off if (P3_5 == 0) {in3_on_2 ();} //IN3 on else { in3_off_2 (); } //IN3 off if (P1_2 == 0) { aux_on_2 ();} //AUX on else { aux_off_2 (); } //AUX off if (P1_3 == 0) { mic_guide_2 (); } else { mic_guide_off_2 (); } }
Thank you
