Re: Schoolproject

Hello You should be able to use the string conversion function ToString to convert the numeric value to an ascii representation. You will then need to send the String (v4) or send the individual bytes of the string (v3). Hey Benj i tried something else for making ASCII code from a byte. Just add 48...

Re: Schoolproject

Hey Medelec35, Thanks for making some time for us. The school allows us the use a lager chip because of al the problems we had. We know use an ECIO-40 from Matrix Multimedia. Buth we have one problem in your program ( see attachment): If we send the beats per minute (BPM) by the way of macro RS232(0...

Re: Schoolproject

Hey medelec35,

I tried to bitbang RS232 from port RB5 to port RA6. So we can use the 7 segments displays and RS232 at the same time.
Can anyone experienced look my code ? Do anyone know how you can make your own 7 segmenten macro in flowcode V3?

Greetz,
Dieter

Re: Schoolproject

Hey Benj, Using a lager chip is not an option because of schoolbudget and efficiency of using pins. It's perfectly possible to use the PIC16F88 for our project. How can we change the macro LED7Seg4(0) ? Because we can only select port A or port b for the whole 7 segments Display. Because we lose RB5...

Re: Schoolproject

Hey Benj, I used your idea in my code. Now we can see after 10 seconds the beats per minute on the 3 x 7segemtendisplay ( see attachment for the program). The intention is to show the beats per minute after 10 seconds on the displays for a few seconds and write this value to the computer and restart...

Re: Schoolproject

Hey Benj, Thanks for helping us so quickly. We used TMR0 overflow for updating the values. On RAO we count the heartpulses. The value "number" counts up if a heart pulse is detected. If 10 seconds are passed the value (BPM) calculate the beats per minute. If we have 6 heart pulses on port RA0 during...

Hey, Matrix The intention of our project is to build a heart rate monitor. We already build the hardware for detecting hartpulses. And this works. On input RA0. We count the positive flanks of the heartbeat signal. And every 10 seconds we multiply the heartbeats with 6. For example: we measured 12 h...
