Unable to display count on LCD display

Dave A · 2019-03-31 19:38

I am trying to display a count on a LCD display. I have worked with Basic Stamp II since they came out, but this is my 1st time for the Propeller chip using SimpleIDE
The following is a copy of my code.
#include "simpletools.h" // Include simpletools
const int ON = 254;
const int CLR = 1;

int main() // main function
{

serial *lcd = serial_open(12, 12, 0, 9600); //Pin12
writeChar(lcd, ON);
writeChar(lcd, CLR);
pause(5);
int cycles = count(16,1000); // Count for 1 second Pin16
pause(10);
dprint(lcd,"count=", cycles);

pause(10);
}

Your assistance will be appreciated.

Here the code I used with my LCD display. I have the baud set to 19200 on my unit.

#include "simpletools.h"

#define ON 22
#define OFF 21
#define CLR 12
#define LEFT 8
#define RIGHT 9


serial *s;
int i;

int main()
{
  
  s = serial_open(0, 0, 0, 19200);
  
  writeChar(s, ON);
  writeChar(s, CLR);
  
  dprint(s, "Hello");
  
  while(1)
  {
    pause(500);
    
  }  
}

Mike, I have no problem getting the text of Count= to come up on my display. What I can not get to respond is the reading of the count input.

Ok, since the program only check once and then stops is it possible the pin is not changing when the program runs.

while (1)
  {
    i = count(16, 1000);
    dprint(lcd, "count=%d", i);
    pause(1000);
  }

Here some more fun code to try:

#define PIN 16

int main()
{

  int Mask = 1 << PIN;

  waitpeq(0, Mask); //wait for low state
  printi("Pin Low\n");
  waitpne(0, Mask); //wait for high state
  printi("Pin High\n");
}
