Yes and its cheap. The problem was the timing. Microchip doesn't have reels of 4431 chips on-hand very often. I had to buy the reel before i was complete with the code. Its pretty cheap to have...

Thank you for the info
I bought ten field programmers last week to atleast get me started on this.
Normally I would have the PICS pre-programmed but I needed to buy 1600 at once on a reel and...
Does the PICKit2 require power from the pcb?
I would really like to program mulitple boards at the same time, not cycle through.
longpole001 has the most appealing idea.
Demon,
I have found another programmer that will do eight at a time, lead time is 6 weeks. I think alot of suppliers must be taking the Walmart approach...
I need to program 400 18F4431 chips ISCP.
I have found Xeltec, looks like they have a high speed programmer. Any opinions on this product or can you offer alternatives?
Yes I know I could have...
I have an agriculture Android based electric motor controller that I use Bluetooth to communicate with the PIC chip(s)
I use B4A (basic for android) It is great.
Example screen shots...
Thank you that helped. I found the right register and I think I have it sorted out.
T3CON.6=0
T3CON.3=1
Took care of it.
Using an 18F6722
It has three ECCP's
In the help file it states "Some devices have 1, 2 or 3 PWM channels. On devices with 2 channels, the Frequency must be the same on both channels. "
Does...
So you have your BT sorted out?
I use a BT chip on my boards with no converter. I have the BT chip running at 3.3v just like the PIC.
I am not sure what you are meaning by handheld device but...
I don't know true seed count as of now. My electric drives work two ways; with a hydraulic rate controller or a rate controller I make based on an Adroid tablet.
For the first example, I have an...
Thank you.
It started out as something Dad and I wanted to do on his corn planter six years ago. Now I have sold over 4000 units in the US, UK, AUS, SA, and Ukraine over the last five years. This...
You can do it that way if you don't want accurate information. When a bag of corn seed costs over $300 (that is a 50 lb bag) you can't take anything for granted and every row is monitored. Plus with...
This is an agriculture application. I am going to measure seed population. The seed rate (population) is dictated by two variables; seed plate count and rpm. Seed plate count is how many seeds are...
I have been working around the PIC chips for quite some time. Built many different products. This one though I am not sure how to do or where to start.
I can have up to 48 frequencies I need to...
When I program the code, LCD toggle's right away. If I cycle power, LCD takes forever to toggle. Any ideas? Internal OSC.
#CONFIG
CONFIG FOSC = INTIO67
CONFIG PLLCFG = ON

Russian joke aside, make your own algorithm.
Write up code to set up your sub to go X speed for Y amount of seconds. X speed meaning a set number for the duty cycle controlling the prop. Make...

One thing you might consider, look at mounting your sensor before the rear tire. You will get better resolution. Or make a reluctor wheel attached to the rear tire. For example, when I was doing data...
Thanks for the suggestion
I am kind of in a bind. I have a board that has three UART TX/RX channels. Ideally I would like to be able to use interrupts and hardware UARTS on all input/outputs. I can only find PIC chips with...
I use the Roving Network bluetooth device. RN-42.
It is pretty easy to use. I downloaded a serial port emulator for my android phone to configure it. Once I realized how the get the emulator to...
Good to hear you got it sorted out.
I have to say if you are turning 3800 at 60MPH, you might need to look at changing rear gears :)
Use this line
AStream.InitializePrefix(serial1.InputStream, False, serial1.OutputStream, "AStream")
instead of
AStream.InitializePrefix(Main.serial1.InputStream, True,...
I did get it working. The one thing that was kicking my ass if I remember right was the True/False for BigEndian.
AStream.InitializePrefix(Main.serial1.InputStream, True,...
