hello

I think there is an error in the "Custom interrupt properties".

Flag register must be "pir1" and not "pie1".

see 16F88 pdf p: 21

I've changed also RS232_RX macro, but it is not tested .

hello Richard LCD (HD44780) has lot of instructions. For scrolling, you can use the Flowcode LCD macro "command" and specify the value of : 0x18 to the LEFT 0x1C to the RIGHT (not available in the simulation) BUT all the 2 (3 or 4) lines are scrolling at the same time. You can also "play" with the c...

Bonjour

Vous pouvez utiliser l'icone "code C" et configurer les registres (voir datasheet du Pic).

J'ai retrouvΓ© ce programme qui a Γ©tΓ© developpΓ© pour un pic 16f88 et avec la version 2 de Flowcode (le PWM est apparu dans la V3 il me semble).

Bon courage

Hello jim

Try one of these Flowcharts.

For "Scrutation", you can use any Port ( A , B , ..).

But for "interruption" , you must use RB0 as input.
Or use RB Port change interrupt and the inputs will be RB4 ou RB5 or RB6 or RB7.

Hello

If you want to stop your programme for good , try this.
For restart, you will have to reset the Pic or power off.

Hello I think the problem is that your 3 boards are not synchronised and your "slave" delays are too long. I've modifed the value of LAMP_x in order to differentiate the first from the other three. The "Slave" flowchart can be almost the same for the two slave boards. Don't send 255, it's a special ...

Hello Did you test the programme on HW with cursor(0,0) ? I think your configuration is not good. Click on : chip / configure / Switch ... The config word is 0x3FFF, it should be 0x3F7A : - oscillator : HS (not RC) - Watchdog Timer: Off - Low voltage Prog : Disable I hope this can help you Daniel

A simple way is to remove all the *.fcd that you don't use from the "fcd folder" (..\Flowcode\fcd) . But keep them in a new folder.
In Flowcode when you create a new flowchart, you will only have your favorite target.

Ron With a 16F88, a resonator is not necessary. In Flowcode, 1- for a frequency of 4MHz you can use a "C code" and put in it : osccon = 0x60; (See page 40 of 16f88 datasheet) 2- Configure PPP with oscillator : internal (menu : chip /configure) STEVE Can i get an update of PPP, I've bought 16F886 and...

A very interesting topic A little suggestion for RB0-interrupt : Choosing the edge activy (like choosing the prescale value for timer) would be great. a PWM macro would be welcome. I use Flowcode v2 with my students (6 and 7 level), they like to see if their program will work at once (or not). Daniel
