It turns out this is not a Flowcode issue. I finally found a way to fix it after reading this post in the sourceboost forums: http://forum.sourceboost.com/index.php?showtopic=5020 Here is an example of supplementary code that loads data into the eeprom starting at eeprom location zero: #pragma DATA ...

So glad you started this post. This issue has been a thorn in my side for quite sometime now, so I understand your reason for posting. This issue is not limited to Flowcode V6. It also affects Flowcode V4 and V5. It is also not limited to that chip. I have not been able to find a target device that ...

I have no idea what happens internally and I don't know where you can look up that information. If you find a good explanation please let me know since a better knowledge of how the stack operates might help prevent overflows. Right now I rely on the compiler letting me know if there might be an iss...

I could be way off in my calculations but, I think this is how you can determine step 1 and step 5. For step 1 you can look at the asm file way at the top and find the interrupt org(might be ORG 0x00000004). It takes 1 instruction cycle to get to ORG 0x00000004. Now count the number of lines after O...

Here is an example using up/down buttons to change a variable.

Great job on catching the missing define. I don't have that micro to test with but, maybe you could try this instead: Define77=#define MX_MI2C For some reason I get a different define number than you and also deleted the spaces. Probably won't make any difference though. I am guessing there is somet...

This is my first attempt at writing to flash and thought I would share what I have so far. This is just an untested experimental program so please don't consider this as a good working program. Use at your own risk. If anyone else has experimented with writing to flash, any tips or comments would be...

Here is a Flowcode version of flash read.

Try turning off the watch dog timer and low voltage programming in chip configure and set the clock speed in project options to whatever the actual speed is and see how it runs.

There are no configuration bits in your program, I wish I could help you in setting them but 18F devices are a mystery to me.

I didn't see any configuration settings in your attached program, maybe you could take a close look at your settings if you just left them blank for the attachment. Also, i don't think any software resets if your using them, like wdt, bor, reset, ect. will clear the stack, only a por will. A good pl...

Try looking here:

Thanks for posting your discovery Desdewit. It turns out that the configuration address in the .fcd files for this entire family needs to be edited. The configuration addresses can be found in table 6.1 in the device data sheet. Please find the line containing "ConfigAddress=" in the .fcd file for t...

Try loading the 18F46j50 with the hex file generated from your 18F25j50 project (since that one works) and see if it now works correctly. If it does work, then take a close look at the changes you made in your 18F46j50 project versus the 18F25j50 project.

Although kersing is correct that wdt is generally used as an abbreviation for watch dog timer, in this particular case it is referring to a delay function. You can view this function in the file PIC_CAL_Delay.c if you like, it is just a delay similar to the delay icon. Flowcode has many behind the s...

I don't see any errors in the compiler message, it says success. As for it not working on your chip, maybe double check you configuration settings, the LCD component macro connections setting. Sometimes adding a 100ms to 200ms delay before LCD initialize display helps with slow starting display modu...

As for your specific use of a macro to convert a decimal value to BCD by "pushing it thru 4 lines", this might be a good starting point for research: http://www.microchip.com/forums/tm.aspx ... &high=btoa
Good luck.

I have the V6 free edition v6.0.4.0(27.11.2013), it is past the 30 day trial, and I get this error when I try to open your project:

Failed to open document.
Attribute <start> is not found

I am very curious how you did the bar graph. Any Ideas on how I can open this?

Thank you for your response Spanish_Dude. The method you posted is probably the simplest and easiest to use. It can also be put into a normal Flowcode calculation box for simulation within Flowcode. It's a great default method. However, a speed test shows it is dead last at 260us. Ouch!

This is a comparison of three different digit conversion methods to get the tens and ones digit which I use for two digit seven segment displays (both led and lcd glass). I needed to determine the best method to use depending on my application. Here are the results of my comparison tests which I tho...

Glad you tried that in hardware, I was curious if it would really work. Maybe Benj's suggestion is worth trying. Does anyone know the V5 equivalent to V6's pow(x,y)? Although pow is a reserved word in V5 I can't get the syntax right. Maybe I just have to use x*x if y is 2 and x*x*x if y = 3?

Seems like the settings of linker/assembler in compiler options are not correct. Have you tried "Restore Defaults"?

I needed to revisit this problem for another project but needed a faster way to do it (vs using switch) and also I needed the length of time to determine the value of the variable to be more consistent. When using switch the length of time to determine the value increases as the value increases. I t...

Does your project work if you use a 4mHz quartz crystal? I do not know of any reason why it would not work using the internal 4mHz oscillator.

I have not tested this in hardware but, it might work. Add this to the top box in supplementary code:
#undef TXEN
#define TXEN CSRC
