I want to use the GLCD_ILI9341 with an UNO. The downloadable file below, labeled "ILIDisplay Test", uses an Arduino MEGA. The connections for the MEGA are MOSI,Clock,Chip Select,D/C.Reset,LED. I am wondering what the connections are for the UNO. The default pins for n UNO are: MOSI is B3,Clock is B5...

I am seeing downloadable Flowcode files labeled, for example "gLCD_ILI9341.fcpx". What is the fcpx file extension? How does it differ from fcfx?
For example, here http://www.matrixtsl.com/mmforums/viewt ... 341#p73847

I am curious what the Flowcode looks like. Or did you use Flowcode?

All's well that ends well. The bootloader was d/l with a USB ASP thru the Arduino IDE. It worked on 4 UNOs.
Thanks to all that responded.

More on the saga of D/L to an UNO: I tried to download a "Hello World" program to 7 UNO's. It worked on 2 of 7. In each case, I looked to see on which COM port the UNO connected, and set that under "Build" "Project options". It worked on COM 9 and 23. I am happy that it worked on 2 UNOS. Wish I knew...

By driver chip, what I see is Atmel MEGA16U2. That # is consistent on the boards I have.

I am at a loss as what to do to solve the problem of not being able to compile to chip. The computers, that do not work, are all older laptops that were upgraded to windows 10. Being able to d/l worked before the upgrade. I can either get a Windows 7 or new Windows 10 computer. I assume that just a ...

Thank you, Some progress has been made. See the message, attached. I matched the com ports within FC and what is reported in Devices and Printers. It did not specifically mention the UNO. So I downloaded the Arduino IDE, and now Device and Printers says "Arduino UNO (Com 5)" I googled the error mess...

It seems that "the system can not find the file specified". See the attached.
I am using Windows 10, and FC Ver 7 professional.

I would like to offer a workshop using the free version of FC ver 7 to seniors in retirement centers in Houston. First I have to get it going. The following is the error code. I get this message with the free version. I can successfully d/l using the AVRISO MkII. C:\Program Files (x86)\Flowcode 7\co...

I was able to key in a value in previous versoins of FC. I assume I accomplished what I intended.
Seems logical though. I am assuming that since I can change the clock speed when I use ATMEGA328P, that this is incorrect also.

I note that when the target chip is changed to the ATMEGA 328P, which is what the UNO uses, (instead of the UNO R3 PDIP) , then you can change the clock speed.

In previous versions of FC, one could change the clock speed. Not V7. The reason I want to do this is that I use Timer1 and overflow interrupt to have a minute variable be relatively accurate during a day, for a solar tracking application. I use a real time clock to update the time daily, to be dead...

Thanks. Was I correct in updating the gLCD_KS0108.fcpx file as listed below? For FC_V6. I have the old one.

I purchased one of these from SparkFun. The interface pin connections are here on page 3 of the following link. <https://www.sparkfun.com/datasheets/LCD/GDM12864H.pdf> I also found a FC v6 example, using the gLCD_KS0108. In the example, there is a RS connection and a Reset connection. What is the di...

Thanks to all. The adding ".0" helped. But there is are still issues in designing an generic program where tone frequency and tone duration are passed to a subroutine.

Nor does this work on the UNO: where variables ending in F are floats. .Period_MicroSecondsF = 1000000 / .Frequency_Hz // Example Period = 1000000/440 = 2272.72... microseconds .Num_PeriodsF = 1000 * .Duration_MilliSec / .Period_MicroSecondsF // Periods = 1000*100 /.002272 = 44.01 .Period_MicroSecon...

The following where .Num_PeriodsF is a float, does not work also.
".Num_PeriodsF = 1000 * .Duration_MilliSec / .Period_MicroSeconds // Periods = 1000*100 /.002272 = 44.01
.Num_Periods = float2int (.Num_PeriodsF) "
Dang.

Thanks. It simulates OK, but does not run on an UNO when I use .Num_Periods in the do_while loop. However if I change the loop counter to "44" it works on the UNO. I thought that since the .Num_Periods is an integer, that the number 44.01 would be cast to an integer, 44. Apparently not. I wonder how...

I have written a program to sound a buzzer (duration and pitch). The while loop controls the duration. The loop count is calculated. But when it is run in simulation, the variable evaluates to zero, and bypasses the loop. Can't figure it out. The program is attached.
Thanks in advance.

The person who developed the Lithium cell boards - asks the following. "Does this mean that the software UART receive char and receive string functions are non-blocking? I am ensuring that the start bit doesn't come in before I call ReceiveChar, but I don't expect the function to return (the flowcha...

The attached photo is of an attempt to code a Lithium battery pack cell monitor. Someone has designed some cell boards that transmit via RS232 individual cell voltage and temperature. The photo is showing the temperature and voltage correctly, when I use the hardware RS232. I am using an Arduino UNO...

When using the AVRISP mk2, I have been erasing the device. I assume that this includes the boot loader. Can I reinstall the boot loader? If so, where can i get it?

BTW, can FC compile and transfer to chip, as indicated by one of the buttons?

You have brought up a very good point. It was a setting within the downloader. Thanks for swatting my brain.
