Re: EEPROM on 18F27J13
Ah! that'll be why... Partly assumed that a pic with lots of bells and whistles would have it and also confused with the flash memory that can be written to whilst the code is running. I need to read up about the differences between them. I will also have a look at the V9 Thanks all your for help, t...

EEPROM on 18F27J13
Hi all Just delving into the world of onboard storage and learning about it so I can use it in a project but have got stuck at the first hurdle. From the wiki I have downloaded the FC for a 16F877A and it runs in simulation but when I port it to my favourite 18F27J13 (only because it is set up and r...

Re: Rain Gauge
Hi Martin That looks brilliant! There are quite a few changes to digest, its great to see and learn how differently you do it, just the simple things like like the day input triggering a loop that runs until the input drops to 0. I had a long delay because there was minimum of a minute trigger from ...

Re: Rain Gauge
Wow Martin! I Wasn't expecting a re write - it must have been bad lol. My methods tend to be quite mechanical whereas you can achieve a result with some slick calculations. I like it and have been studying and changing some of it just to see how it works. Definitely open it up for more than 10mm as ...

Re: Rain Gauge
Nearly there with this. The closest i can get on the display is: 2.2 4.4 6.6 8.8 1.0 1.2 1.4 1.6 etc to 9.8 then it rolls over to 1.2. Increasing the string length to [2] to get beyond 10 makes the addition much worse. Is there some way of blanking or converting the double number in the first 4 addi...

Rain Gauge
Seeing as I have had so much rain recently I thought I would revisit an old shelved project. The Gauge sender unit has a transmitter that triggers a receiver relay for every 0.2 mm of rain. Simply adding 0.2 or 2/10 eventually gives a rounding error so it no longer is adding an even decimal number. ...

Re: UM3750 Emulation
hi all I had at go at bastardising the component macro to learn about it and build my version just a macro call and it is remarkably similar! I can now understand how it outputs the data in reverse order to what I want, so I reversed the data before sending it. It works although I have not fully tes...

Re: UM3750 Emulation
Thanks Ben, nowt like missing the obvious :oops: I have been having a good play and can transmit a 2 channel receiver but have no control over individual channels. Turns out it is only sending the last 8 data bits anything before that gets sent as a 0. Also seems to be sending in reverse order as no...

Re: UM3750 Emulation
Struggling with this as I cannot see where in the properties to set the output pin to C1 and a delay of 700uS as just not seeing the option.
Using a variable to set the output code is as far as I have got, any pointers would be great help, thanks
Ian

Re: UM3750 Emulation
Wow! Thank you Ben, that will make a fab starting point. My aim is to make the low byte an address and the remaining 4 bits will be for control, ie on/off.
kind regards

Hi Has anyone have experience of emulating the UM3750 encoder/decoder, I am more interested in encoding as I want to transmit into an existing scantronic receiver. A google search shows an Arduino sketch so it has been done but I have no idea about interpreting it! I have controlled a UM3750 directl...

Re: Ports A6 & A7 not accessible
You are a genius Martin, my mistake was to allow FC to do an update which rolled the file back!
All good now, thank you!

Re: Ports A6 & A7 not accessible
Hi Martin
Thank you for your reply, I have replaced the file and reloaded FC but the ports remain grayed out, would you mind having another look please.
Many thanks Ian

Hi all I am setting up another project with the settings based on a previous working setup driving a GLCD. I want to use ports A6 & A7 but they are grayed out as if in use as OSC1 & OSC2, I think I have disabled all usage of the external oscillator functions to release the ports for general use. Hop...

Oh yes that has compiled to an accurate signal! I can now play with some variables for different outputs. Don't know whether I have read it wrong but on the Project options I have to set the "PLL Configuration Enable Bit" to Enable if I am not using it. On another project when I was using the PLL at...

I have seen you use that last decision in other flowcodes "If Enable ?" thinking it looks incomplete but its works!

Re: Piezo Sounder accuracy
Hi Martin Got there in the end, the timings are spot on now but I will adjust the configuration settings some more to see what breaks it. The timer calculator now loads without a hitch - pure genius! I have been playing with gating the output on and off at 1Hz, probably crude but it works and its ev...

Hi Martin Thank you so much for this, it makes a great platform to start from. A couple of things, there always are (!) my output frequency was 100Hz so I changed the post scaler to 1:1 and got 1.003 KHz which is pretty bang on, I had confidence that the config was correct until I added the 1 sec pu...

Hi Martin I hadn't really thought about how many pins I will need as I was only thinking about getting the output frequency and timing sorted first within the confines of my existing board and it is confining so time to move on!

I am creating a new project based loosely on an earlier project where I had issues getting the frequency and timing to work with any degree of accuracy so I thought I would start with this. With it complied and running in a pcb I am getting a 640Hz (set for 1000Hz) tone with a 1.5 second duration, t...
