Hello everyone. I am trying to design a prototype for a fairly simple motor controller using a Tiva EK-TM4C1294XL board and Energia. I have a 20x2 char LCD, 5 buttons and 3 output signals. Buttons are momentary switches for, respectively, 1) going up while pressed and stopping and waiting in standby when released 2) going down while being pressed and stopping and waiting in standby when released 3) going to bottom when pressed once 4) going to top when pressed once and 5) stopping due to emergency (stop while being pressed and standby when released. I am not going to include the 3 output signals into the discussion because they are easy to handle later. For the 1st and 2nd buttons, I thought it would be best to use the interrupts being fired at RISING and FALLING edges, so that I would start running the motor when the putton is pressed and stop it when the button is released. However, my problem is that when I press and keep pressed the 1st, 2nd and 5th buttons, my code prints "READY" on my LCD, which means standby, as if the button is released. Can somebody please explain me what I am doing wrong? Below is my poor code. #include <LiquidCrystal.h> #define RS 31 #define EN 32 #define D4 33 #define D5 34 #define D6 35 #define D7 36 #define asagi 42 #define yukari 43 #define tamasagi 44 #define tamyukari 45 #define acil 46 #define upled 6 #define pwmenable 7 #define downled 8 int i=0; int j=5; LiquidCrystal lcd(RS, EN, D4, D5, D6, D7); void setup() { pinMode(upled, OUTPUT); pinMode(pwmenable, OUTPUT); pinMode(downled, OUTPUT); pinMode(asagi, INPUT_PULLUP); pinMode(yukari, INPUT_PULLUP); pinMode(tamasagi, INPUT_PULLUP); pinMode(tamyukari, INPUT_PULLUP); pinMode(acil, INPUT_PULLUP); lcd.begin(20, 2); lcd.setCursor(0, 0); lcd.print("01234567890123456789"); lcd.setCursor(0, 1); lcd.print("01234567890123456789"); delay(1000); lcd.clear(); digitalWrite(upled, LOW); digitalWrite(downled, LOW); analogWrite(pwmenable, 255); attachInterrupt(asagi, startgodown, FALLING); attachInterrupt(asagi, godownstop, RISING); attachInterrupt(yukari, startgoup, FALLING); attachInterrupt(yukari, goupstop, RISING); attachInterrupt(tamasagi, gobottom, FALLING); attachInterrupt(tamyukari, gotop, FALLING); attachInterrupt(acil, startemergency, RISING); attachInterrupt(acil, emergencyend, FALLING); } void startgodown() { lcd.clear(); lcd.setCursor(0, 0); lcd.print("ASAGI"); // Go Down } void godownstop() { lcd.clear(); lcd.setCursor(0, 0); lcd.print("HAZIR1"); // Ready1 } void startgoup() { lcd.clear(); lcd.setCursor(0, 0); lcd.print("YUKARI"); // Go Up } void goupstop() { lcd.clear(); lcd.setCursor(0, 0); lcd.print("HAZIR2"); //Ready2 } void gobottom() { lcd.clear(); lcd.setCursor(0, 0); lcd.print("TAM ASAGI"); //Go to bottom } void gotop() { lcd.clear(); lcd.setCursor(0, 0); lcd.print("TAM YUKARI"); // Go to top } void startemergency() { lcd.clear(); lcd.setCursor(0, 0); lcd.print("ACIL"); // Emergency lcd.setCursor(0, 1); lcd.print("DURUM"); } void emergencyend() { lcd.clear(); lcd.setCursor(0, 0); lcd.print("HAZIR3"); //Ready3 } void loop() { // do nothing } -

i have build a homemade ppm decoder with CD4017 ic together with 27mhz fm transmitter and receiver. The 27mhz transmitter/receiver work correctly because i can hear the tune when connected to a small speaker, but the problem here is: despite that the encoder and the decoder working correctly when connected via negative and signal terminal directly to the decoder, it refuses to work with the remote module that i made and i dont know why is happening so. is there anyone who can tell me the problem? -
