works great...THANK YOU FOR YOUR WORK!!!

no problem...your the one bearing with me!!!

Hello Your program was doing strange things because you were trying to do a lot of floating point calculations using integer variables. I have ammended your program so that it now uses the floating point functions. Note this may have increased the compiled program size significantly. If the calcula...

Ok, here is what I came up with. For some reason the math does not work out when the ADC is below 31 (byte) and posts negative numbers (on freq setup). Should work fine but maybe its a bug. I also noticed that the LCD position is off by one...Im not sure if anyone else got this? For example when the...

I have a meter that's capable of measuring Hz and duty cycle but I'm away from the car at the moment. I understand what pulse width modulation is and how it works in motors but not how its utilized in flowcode. Here is some info Ive found but cant confirm until I get back home (a week or so) Apparen...

Id actually like to see it adjustable from 1-100Hz first...Im being told that the plunger in the solenoid probably cant move faster than in this area. I have try and read the Hz in a car with this transmission to get the exact number. Anyone?

Hello, I've never been successful using the PWM component and was hoping to get some help. First a little background on the project: I've finished working on a automatic transmission controller (this is a different transmission than the computer was intended for)and everything works great except one...

Id like to get a complete grip on CAN technology...Almost all of my projects have something to do with cars and it would be so amazing to stop using external sensors to get values when there are sensors in the car already. (and in better spots) I also design/etch my own boards so I would not be usin...

Im really looking for a way to get coolant temp, speed and rpm only. I'm really not interested in checking codes or clearing lights or any other information. I just want to be able to take the live data from those sensors only. Would your CAN solution help me learn what I need to kind of get started...

Just want to gather some opinions from the experts here. Ive been thinking of a project which involves OBD II live data and a PIC. How hard would it be to modify an OBD II kit like this one: http://obddiag.net/index.html to output live data to a PIC? I know this reader is made with PIC's and outputs...

I know this is probably the basic of the basics but I think this would help out more than just myself. Ive attached a simple flashing led flowcode. Can someone please edit the oscillator for RC, XTAL and internal AND post a schematic of the connections required to get it to work in all configuration...

Can someone tell me for example which bit on port A corresponds to what pin on the port A 9 pin D connector?? Id like to build my own "e-blocks" for various projects. Are all bit "0" on the same pin on all ports for example? This is for the EB006 programmer board btw. THANKS!!

Hi Boa, I downloaded you FCD file but you left out the range macro.. Not sure what happened but I just downloaded it and the RANGE_SET macro is there. One other little thing you may have to look at is Port A for the leds. As the analog inputs are on port A but this could be changed to port E. Good ...

I was just playing with something and noticed how tedious it was to get what I want accomplished. This came from an Idea to make a scale of sorts where a pressure sensor measures weight. The program lets you pick a low limit on an ADC component (the scale) and sets that at zero percent. Then you set...

Exactly what I was looking for...THANKS!!

I might just be retarded but how is an ADC item actually connected. There is no schematic in the help files. Im going to use a POT as an example: im guessing 5 vdc is applied to the pot wiper and either end is applied to the pic depending on whether I want ascending or descending values...correct?? ...

For in-circuit programming, just expose the following pins on your target board: RB6 RB7 Vcc Gnd MCLR If you are using the LVP capability of the chip, also expose RB3 (or whatever the LVP pin is). This should be the same for most of the PIC16 and PIC18 chips. Im not sure what you mean by "expose" t...

what actually happens is readable but not accurate. Example: Fi%sT T^Y: Transmi@e9n it displays crazy stuff like that over and over...the program only calls for this once but its like its resetting every second or so and repeatedly trys displaying First test, transmission over and over..buttons do n...

It is one of those push pin type boards and Ive heard of the capacitance thing assosiated with these prototyping boards...what else can Iuse to test cuircuits without them? Im going to have to try something else.

and the last one

As I said, both of these programs work fine on my hardware, so there is nothing wrong with the programs. The setting of the osccon register is ok. Perhaps the 2MHz speed is too fast for the breadboard project? Hmmm ...I wonder why its not working on the breadboard?.? Im kind of nervous etching out ...

I've downloaded and tried both of these programs and they both seem to work fine (at least the LCD is displaying correctly). Could you also post the C and HEX files for both of these programs - this may help troubleshoot the problem. Like I mentioned...the no-osccon file works perfectly on the brea...

Well, I started my flow code from ground zero and it works perfectly!! Don't know whats wrong with the original code but I suspect it had a lot to do with the multiple changes I made while building it. (variables that were there but not used..maybe the interupt I was using which was also a data outp...

Here is a schematic...is this at least correct?

So here is an update...this is so frustrating. I can get a 16f88 to display text correctly ONLY if the clock is set at 31250 and oscilator to "internal I/O" With this configuration it will display what I want almost perfectly...almost because every now and then a letter or two changes. If the text i...
