Hi benj , the data output as you have suggested, does not realy relate to what i get, if i make variable string as `variable[111]` . This is the maximum size i can get working, this comes up with memory data as ` 758 out of 8192 program words used 0 out of 256 data bytes used That took 1.61 seconds...

Hi , i wonder if you could suggest what could be done here. I setup the prog multi servo2 so that the potentiometer reading pointed to another number from a list, and this list/number is the one used to operate the servo. All works ok in flowcode but i could not down load it onto the development bo...

Hi sean , i have been playing around with your new prog, i must say it is a lot better. :mrgreen: i did a rough bench mark with the other one...sort of similar setup...and the first prog you sent to try (as i set it up with my altered version :P ) came out at doing a 200 cycle in 10 seconds. Your n...

Hi sean, thanks for the effort you have given this and for the explanation, i do appreciate it. I note that you have been here on the forum today - a saturday. i thought i might let you know what i have done , i tweaked the `77` to a `52` which adjusted the potentiometer on the development board to ...

HI me again , i have been playing around wth the prog you made up. Works ok. :mrgreen: but i have a few questions you may be able to shed some light on. I set up a program based on yours, with a button which puts a 5 into the servo position when NOT pressed, and a potentiometer which gives it`s num...

Thank you very much benj and sean, i shall have a little play with your prog for a while.
Glad that it is me not getting it right! and not expecting too much from the flowcode!
I have the pic 16F877A that came with the development board.

Hi all , well i`m sorry to say i could do with some help again,after setting up a simple program to use pwm to operate a led, working off the potentiometer on the ver3 development board, all seemed ok as the led dimmed as expected. Next step was to replace the led with a servo as found in r/c model...

EUREKA ! :lol: Hi, thanks benj, i have put together a sightly simpler version of your `ADC CONTROLED PWM` program by editing it (as proof i understand it and to change the chip). I have got a led to work dimming in proportion to the pot an1. What i did not realise when i used it before you explaine...

Hello chevy There is a ADC controlled PWM example available from the downloads section of the website that will show you the LED getting dimmer and brighter with regards to the POT on AN1. You will have to switch the RA1 jumper from Digital to Analogue on your dev board to see it working. I have be...

Hi again, i think i am getting closer ! O.k. i can get the led on the development board to dim according to a pwm duty cycle setting, but i would like to get straight why the delay is needed, as if it is needed for the led to be seen working, would i need the delay if i connected it to a servo? Can ...

Hi benj, thanks for the input but you miss understand my intentions, the reason for me to try and operate the led in flowcode is because there is no servo component, and i hope a led would make use of the pwm function, it is the pwm function i need to get to grasp. I hoped to be able to see flowcode...

Hello What I really like to see is a servo component and a servo signal input component. These two are quite tricky to program using the present components and it is even harder to have them both in one program. I second the above. :mrgreen: There is a growing push in industry to use pwm to control...

Hi again, well o.k. so the software cannot flash the leds but should it not be possible to make them come ON or OFF. I setup a simple program (chip 16f88), that uses a switch to switch a pwm to max of 255 when pressed and to set pwm to min of 0 when not pressed. I setup a row of leds on port B so th...

Hi, tried your `adc controlled pwm` program, i can see how it all works but as proof of concept i thought that it should be possible to have the signal opperate a led or leds. So i thought all that was needed was to slap on a row of leds on port B and i should be able to see port B bit 0 and bit 3 c...

Hi all, from what i can see on this forum there are a few like myself who would like to know more on how to use the pwm function. I have already picked up the fact that flowcode will only display 2 pwm functions even if the chip has more!....hope this is put right in the next update!.....I have alre...
