Re: 16F1827 Read 1/2 pulse

Martin, And all others following this...... This is what I would call the final version. Running at 32 Mhz Really corrected accuracy issues EEPROM Read/Write is working. (had to paste in the C code for EEPROM to work) IR Zero/Home position sensor is working. (Not wired to the PIC) Positioning is +- ...

Beginners tips for beginners

I just finished my first project using flowcode V4 for PICs. I thought I would list a few things for first timers like myself. My project was to replace an every day TV antenna rotor control with something with position feed back and greater range of travel. 1) Define you project on paper. What do y...

Re: Help choosing a PIC

Thanks for the info everyone.
I have decided to use the 18F4455
It may be a bit overkill for my needs but have already added 2 more I/O functions to my list.
I also see it has 3 interrupt pins, and on paper is plenty fast.
Best part is that FC5 supports it.

Re: Simple project does not run

I went back and looked at my original that did not work and saw my mistake. I should post this one under some of the demo programs. I have seen many post with people looking for the proper code for various LCDs. It kind of has the added bonus of letting you actually see the character on the display....

Project Control Humidifier

This is a project in progress. I am posting this so it may help others with similar projects. Scope: Control a HVAC humidifier based on OUTSIDE air temperature and INSIDE HUMIDITY. Prevent moisture build up on windows and doors during the winter time from too much moisture in the air. Winter time he...

Re: Project Control Humidifier

TempHumid.jpg Been slowly building the actual board. Have every thing finished except an LCD display. Ones I had were bad, no wonder I got them for a dollar each. Here is a picture of the completed board. I used screw terminal connections for the AC in, the temperature probe , and the switched AC o...

Re: Project Control Humidifier

Yes I will provide a list of the components I used. I had to use separate temperature and humidity sensors as I am measuring OUT door temperature but IN door Humidity. I purchased most of my items from MOUSER here in the USA Humidity sensor is a Honeywell 785-HIH-4010-001 http://www.mouser.com/Searc...

Re: Help With Temperature

Thanks to this post: http://www.matrixmultimedia.com/mmforums/viewtopic.php?f=7&p=56523#p56523 I have it figured out and working. For those also building projects, do read other post, down load the included charts. It took me looking at 3 other examples before I understood how the LEFT and RIGHT...

Re: Running out of Memory

Darn, Missed that one. changed it to 102 Amazing how much a float value will eat up. RAM available:384 bytes, used:120 bytes (31.3%), free:264 bytes (68.7%), Heap size:264 bytes, Heap max single alloc:79 bytes ROM available:4096 words, used:1849 words (45.2%), free:2247 words (54.8%) Thanks Ben........

Personal Thank you!

To Ben, Martin and the rest of the flowcode team. I want to personally and publicly thank you for all your support. Was having a bugger of a time with memory management, flowcode version and then some. Planning is everything, and so is understanding ADC interactions and some basic math. Soon as my n...

Re: Understanding a calculation

I am writing this in hoping it will help others. I have been wrestling with a simple calculation to permit temperature readings and display with out the use of memory intensive float values. It finally dawned on me I was fighting ADC resolution when using a 5 volt reference. At 5 volts, the best you...

Re: Reading LM35 Temperature IC

James, I ran into the same dilemma as you. I am using an LM35 equivalent that reads -40C to 125C 10mv per degree C. I do not know the PIC you are using, but going on the assumption that you have a 10 bit ADC 0-1023 If using a 5 volt supply, each ADC step will be worth 4.88MV If using a 3.3 volt supp...

Re: Can't figure out how to break in/out of loop

Ionize, I think you have too many loops, or loops that lead you no where: In your get_mesurments Macro you have several loops set as Loop While, these leave you trapped in the loops. You should either have them set to only loop a set number of times, or provide a way to go elsewhere in your program ...
