Re: Button press interrupt

The solution that I chose was to just check if a button press is sensed in Main. Since it detects any 1 of 5 buttons. Forget the interrupt.
I also found out that on the MEGA, that Analog Input 0 is on Port F and IOC PortF (interrupt on change - Port F) is not available.
Thanks for the suggestions.

Re: Programming to Mega 2560 - No Permissions

Thank you, I did purchase and install the ARD component. I am running into another challenge now - confounding. I sucessfully programmed the MEGA 2560 R4 "Hello World" program. Then I started expanding the code, and now it will not work. The errors vary. The latest message is that it "times out." Th...

Programming to Mega 2560 - No Permissions

I am having to use a MEGA instead of the UNO because the HEX file size is too large. The 2 picture files, attached, are the permissions dialog and the error text, cited below. The error message is "You do not have a valid license to perform this action." The permissions dialog indicates I have the A...

So I am look for recommendations for the hardware, and some sample code (FC8) to get started. what I can find is here but sorting thru it is a challenge. https://www.matrixtsl.com/wiki/in...

Re: Button press interrupt

I implemented the code to where the interrupt handler sets a global value. I have the same problem, in that 2 of the buttons do not set the MenuPosition (global value) and display text indicating so. I note that the 2 buttons that do not respond have the highest analog voltage - 2.2 to 3.2 and 3.2 t...

Button press interrupt

The attached image shows a 5 button shield plugged into an UNO. When I press a button, the software shows the millivolt range that is tested for, and the actual millivolts read. The 5 buttons on the LCD form a voltage divider with an input to AN0. In one version of the program, I enable the interrup...

Re: Installing Flowcode Ver 8 on a new Laptop.

That appears to have worked. As usual, thank you Martin.
I am surrprized that on the newer laptop and operating system
that when I choose Build / Project options that the dialog is different
in terms of identifyong the port where the UNO resides. See the image attached.

Installing Flowcode Ver 8 on a new Laptop.

I had do do so because of hardware problems on an old laptop. So I need to know how to do so. I am running Flowcode, but my install does not know which components I have paid for. The message when I compile to chip is "AVR Toolchain is not installed. Visit http://matrixtsl.com/flowcode to download"....

Re: RTC componrnt macro

I do not know what I got correct / changed, but this program works. If the time is 8:32, the Min From Midnight is 512 = 60*Hours + Minutes
Now to integrate it into the main program for a 2 axis Solar Tracker

Re: RTC componrnt macro

I have to add, that before I used the RTC component macro, that I used the following code to create MinuteFromMidnight. Maybe this is part of the solution. .HourFromRTC = (.HourFromRTC >> 4) * 10 + (.HourFromRTC & 15) .MinutefromRTC = (.MinuteFromRTC >> 4) * 10 + (.MinuteFromRTC & 15) MinuteFromMidn...

Re: RTC componrnt macro

My post was a dump post. Mine works on the hardware. I will post something later that does not work.
In it, I go thru the process of setting the minutes,Hours,Month and Day of month. Then disconnect power or reboot, and the DS3231 does not retain the numbers, as they come up as 0:00.
