Tool/software: TI-RTOS

Hi everyone, I'm working with the communication between two cc1310 through set commands. I am experiencing a problem with this communication. I would like to turn on the LED from a second device, by pressing the button of the first device. When I press the button, the LED of the second device turns on and off by itself and sometimes not. I saw the PIN of the button with the multimeter and when I press it doesn't go to 0, but it returns to 1 automatically. These are my configuration codes:

mycode.c: 

Button1 | PIN_INPUT_EN | PIN_PULLUP | PIN_IRQ_NEGEDGE,

CC1310DK_7XD.c

BUTTON1 | PIN_INPUT_EN | PIN_PULLUP | PIN_IRQ_BOTHEDGES | PIN_HYSTERESIS,

mycode.c

if (PIN_getInputValue(Button1) == myvar)					
		{
   		  if(myvar==0){
   		    PIN_getInputValue(Button1) == 1;
   	            myvar = PIN_getInputValue(Button1);
   		    strcpy(From_uart,"#011");                          //SEND COMMAND
   	            return;
		} else {
		    PIN_getInputValue(Button1) == 0;
		    myvar = PIN_getInputValue(Button1);
   		    strcpy(From_uart,"#010");
		}
		}

Try to set breakpoint at everywhere it would turn off led to see where your application turns led off.

The part of code that I write it's correct?

0 YiKai Chen over 6 years ago in reply to Mark Felberg

Guru 735685 points

Actually, your codes looks no good, for example, “PIN_getInputValue(Button1) == 1;” is not correct C syntax.

0 Mark Felberg over 6 years ago in reply to YiKai Chen

How could I set it?

0 YiKai Chen over 6 years ago in reply to Mark Felberg

Guru 735685 points

What do you mean “How could I set it?@

0 Mark Felberg over 6 years ago in reply to YiKai Chen

Guru 19990 points

I set the my code in this mode:

static int myvar = 0;

if(PIN_getInputValue(Button1) == myvar){
myvar = PIN_getInputValue(Button1);
myvar == 0;
strcpy("send command");
} else {
myvar == 1;
strcpy("send command");
}

can go?

0 YiKai Chen over 6 years ago in reply to Mark Felberg

Guru 735685 points

No, it’s no good. Why do you use wrong C syntax “myvar == 0;” again?

0 Mark Felberg over 6 years ago in reply to YiKai Chen

Guru 19990 points

How can I send one and zero with command pressure?

0 YiKai Chen over 6 years ago in reply to Mark Felberg

Guru 735685 points

What is “command pressure?”

0 Mark Felberg over 6 years ago in reply to YiKai Chen

Guru 19990 points

When I press the button I send the 0 and 1, how can i make this? The code that I send you, it's wrong. It's correct?

0 YiKai Chen over 6 years ago in reply to Mark Felberg

Guru 735685 points

Your code looks incorrect and I don’t see you do RF TX to send 1 or 0 in your codes.

0 Mark Felberg over 6 years ago in reply to YiKai Chen

Guru 19990 points

Yes, because I send you only part of command. How can I send the command 0 or 1?

0 YiKai Chen over 6 years ago in reply to Mark Felberg

Guru 735685 points

Which RF protocol do you use on your CC1310? TI 15.4 Stack, Easylink Paecket TX/RX, or something else?

0 Mark Felberg over 6 years ago in reply to YiKai Chen

Guru 19990 points

TX/RX RFpacket example

0 YiKai Chen over 6 years ago in reply to Mark Felberg

Guru 735685 points

In PacketTX/RX examples, it already shows you how to send message so what’s your question?

0 Mark Felberg over 6 years ago in reply to YiKai Chen

Guru 19990 points

Maybe you don't understand. I can communicate with my second device. I from the first press the button from the second you have to turn on the LED. With the code I've posted, I press the button and the LED lights up, repress and off. Sometimes when the LED is off, I press to turn it on but it goes off by itself

0 YiKai Chen over 6 years ago in reply to Mark Felberg

Guru 735685 points

Are your posted codes intended to turn on/off led on the device that you press button? Also, your codes contains C syntax problem so you should check what you are doing by yourself anyway.

0 Mark Felberg over 6 years ago in reply to YiKai Chen

Guru 19990 points

When I press the button, the PIN is 0 and return to 1. Can I when I press the button set the button to 0 and when I repress return to 1?

0 YiKai Chen over 6 years ago in reply to Mark Felberg

Guru 735685 points

I couldn’t understand your descriptions. It reads non-sense to me.

0 Mark Felberg over 6 years ago in reply to YiKai Chen

Guru 19990 points

Use the multimeter to measure the PIN of the button. When I press the button, it becomes 0 and when I release it returns to 1. I wish that when I press it remains at 0 and to become 1 I have to press again. It's possible?

0 YiKai Chen over 6 years ago in reply to Mark Felberg

Guru 735685 points

Button is GPI so you cannot expect it to act as GPO at the same time. I don’t think what you want is possible.

0 Mark Felberg over 6 years ago in reply to YiKai Chen

Guru 19990 points

When I press the button I have to send 1 and when we repeat I have to send 0 with a command that I set.

if(PIN_setInputValue(Button1) == 0){
myvar = PIN_setInputValue;
strcpy("1");
} else {
myvar = PIN_setInputValue;
strcpy("0");
}

It's correct?

0 YiKai Chen over 6 years ago in reply to Mark Felberg

Guru 735685 points

No, it’s incorrect.

0 Mark Felberg over 6 years ago in reply to YiKai Chen

Guru 19990 points

Why?

0 YiKai Chen over 6 years ago in reply to Mark Felberg

Guru 735685 points

Because button is GPI. You can only get pin value from GPI pin and cannot set value to a GPI pin.

0 Mark Felberg over 6 years ago in reply to YiKai Chen

Guru 19990 points

Ok, but I want to send the command. When I press send 1 and when I not press send 0. How Can I make this?

0 YiKai Chen over 6 years ago in reply to Mark Felberg

Guru 735685 points

Let me clarify one point first. When button is not pressed, do you mean to continuously send 0?

0 Mark Felberg over 6 years ago in reply to YiKai Chen

Guru 19990 points

0 YiKai Chen over 6 years ago in reply to Mark Felberg

Guru 735685 points

So, you actually want to send 1 when button state is from not-pressed-to-pressed and send 0 from pressed-to-not-pressed, right?

0 Mark Felberg over 6 years ago in reply to YiKai Chen

Guru 19990 points

Yes

0 YiKai Chen over 6 years ago in reply to Mark Felberg

Guru 735685 points

Try to refer to example in sunmaysky.blogspot.com/.../how-to-detect-buttont-hold-in-cc26x2.html

0 Mark Felberg over 6 years ago in reply to YiKai Chen

Guru 19990 points

Should I to copy this part of code?

  if(PIN_getInputValue(keyButton1) == false){
            button_pressed_time=Clock_getTicks(); //Clock_getTicks will return counts in 10us.
            return;
         } else {
            if (PIN_getInputValue(keyButton1) == true){
                button_released_time=Clock_getTicks(); //Clock_getTicks will return counts in 10us.
            }
        }
        if ( (button_released_time-button_pressed_time)>300000 )
            keysPressed |= KEY_RIGHT_HOLD_3SEC;
        else if ( (button_released_time-button_pressed_time)>0 )
            keysPressed |= KEY_RIGHT;
    }

Please study the example code that shows you how to detect high/low status on GPI pin and revise it for your own application.

0 Mark Felberg over 6 years ago in reply to YiKai Chen

Guru 19990 points

Sorry Yikai, I was trying my example again. I noticed something. When I send the command, I turn the LED on and off when I press the button. Those times I send and the LED turns off by itself is like sending the command twice. Can this be solved through a pin configuration?

I haven't read through the full thread since it's not very information. But have you implemented some sort of debounce logic on your button press?

0 Mark Felberg over 6 years ago in reply to TER

Guru 19990 points

Hi TER, I'll explain my problem in a few words. I have created a communication between two CC1310s. Using the DEVICE1 button, I would like to turn the DEVICE2 LED on and off. When I press I turn on the LED, when I re-press I turn off the LED. I do this, but sometimes when I press the button, the LED turns on and off automatically. As if receiving two commands and pressing the button. The LED turns on and off many times

0 YiKai Chen over 6 years ago in reply to Mark Felberg

Can you show me your latest codes?

Mark, please answer me question.

0 Mark Felberg over 6 years ago in reply to YiKai Chen

Guru 19990 points

This is a part of my code that send the command:

static uint8_t myvar;
static uint8_t value[5];                

                if (!PIN_getInputValue(Button1))					
		{
   		    myvar = PIN_getInputValue(Button1);
   		    strcpy("ON");                                            //SEND COMMAND
   		    System_sprintf(value, "%d", myvar);
   		    UART_write(uart, value, 2);
   			return;
		}

I put the uart for to help me. When I push the button send a value and the led is on, but many times when I push the button I see two value, how if it send the command two times

I answer you

0 YiKai Chen over 6 years ago in reply to Mark Felberg

Guru 735685 points

I couldn't understand your coding logic, especially, why do you use "if (!PIN_getInputValue(Button1)) ..."?

0 TER over 6 years ago in reply to YiKai Chen

TI__Guru**** 317180 points

Mark: I asked: Have you implemented some sort of debounce logic on your button press? In which post have you answered this?

0 Mark Felberg over 6 years ago in reply to YiKai Chen

Guru 19990 points

Sorry this is the my old code. See this:

static uint8_t myvar;
static uint8_t value[5];

if (PIN_getInputValue(Button1)==0)
{
myvar = PIN_getInputValue(Button1);
strcpy("ON"); //SEND COMMAND
System_sprintf(value, "%d", myvar);
UART_write(uart, value, 2);
return;
}

I suggest you to use scope to check if there is jitter on button 1 GPI signal.

0 Mark Felberg over 6 years ago in reply to YiKai Chen

Guru 19990 points

I not understand. Can you explain?

0 TER over 6 years ago in reply to YiKai Chen

TI__Guru**** 317180 points

All mechanical buttons will most likely have jitter and hence need debounce logic.

I have not received a yes/ no answer if this is implemented or not.

0 Mark Felberg over 6 years ago in reply to TER

Guru 19990 points

0 TER over 6 years ago in reply to Mark Felberg

TI__Guru**** 317180 points

Please show the code for the debounce.

0 Mark Felberg over 6 years ago in reply to TER

Guru 19990 points

I posted yet, I show my code to Yikai

0 YiKai Chen over 6 years ago in reply to Mark Felberg

Guru 735685 points

Your code doesn't show anything about debounce.
