Hello all
I've got all the symptoms listed here when trying to program an i2c LCD in flowcode 7, I've downloaded the update as suggested but not sure that I'm applying it to the flowcode 7 folder correctly as I'm still getting the same errors, can you help ?

Can you please describe your issue and perhaps post the error messages, your Flowcode file and the C code generated. That will make it easier to get this problem sorted for you.

ok so I've done a very basic diagram consising of lcd start-lcd clear-lcd set cursor-lcd print string, to test the screen and this is what i get when it tries to compile.

I've followed the thread re downloading the and extracting the zip file and applying it to the flowcode7 folder but I'm not sure that I've done it correctly.

Hi andy
can you post your flowcode file as it will enable others to better help
Regards
Dazz

Thanks Dazz
Here you go.

Hi Andy,
Compiles for me OK using the latest updates running V7.3.0.7: What I do is open the zip file select all with Ctrl a, Copy with Ctrl c, then paste in the correct directory.
For 32 Bit windows:
For 64 Bit windows: It appears that your V7 as not been correctly updated?

Martin

Hi
i just did the update on my pc from this link
https://www.matrixtsl.com/temp/FC7_Late ... -05-18.zip
follow Martins post to move the files,and it will work

Thanks Dazz
Success up to a point, it's compiling ok now but I can't get it to upload to the board, I've also tried to upload a diagram that uploaded fine before the update, please see error message below.

Hi Andy,

Which Arduino are you using? Does it say R3 on the PCB?
If it does then make sure you have selected the R3 version of the target and then hopefully programming will complete successfully.

I'm also guessing COM5 is the correct port for your Arduino?

The Target and COM port are both specified in the Project Options window if you need to change them.

I'm using the arduino nano 328 which I have it set to in the project options and yes it's set to com5.

Hi,
Could you try the attached file, to replace the one in your Flowcode7 installation \compilers\avr\batchfiles directory

C:\Program Files (x86)\Flowcode 7\compilers\avr\batchfiles

Bingo, thanks LeighM, I have a connection to the board now and a simple blink diagram uploads and works, however I can't get the screen to display anything, it's a 16x2 screen with backpack and I have established that the address is is 0x27 which I've set as 39 in the component configuration and the SDA line as C4 and SCL line as C5. I've had the screen working using the Arduino IDE so I know it works, any suggestions ?

Hello,

Can you point us to which display you're using i.e. a link to the display/backpack for sale or information on the display/backpack and I'll investigate for you.

Thanks Benj, please see link below.

https://www.ebay.co.uk/itm/With-Without ... 2749.l2649

Please can you try address 63 instead and see if you have any more success with this.

Based on this from the description.

- I2C Address: It's either 0x27 or 0x3F
- Received an email from a customer saying that his board works with 0x3F

Thanks Benj, I have tried that, I'm sure it is 0x27 because I had it working with the Arduino IDE on that address.
In the component configuration, should the channel be set to software or channel 1 ?

hI Andy

Sorry for the late reply i had to hunt down the bits
Ok change fron software to channel 1 as you mentioned above also connect as follows
SCL goes to pin A5
SDA goes to pin A4
%v to the 5v pin on the nano
gnd to gnd

i have had your file running

Regards
Dazz

Thanks Dazz
I have it all set up as described but obviously something isn't right, all I get is a blank screen, I've tried a different Nano and a different screen as well (same address) but same result. It compiles fine and uploads fine.

Hi Andy
try adjusting the pot on the back of the i2c adapter, turn it untill you get a screen full of black blocks , then turn in the opposite direction until you hopefully see the words.

also find the hex file for the program, zip it up and attach here i will then download ant try it here, that help narrow down the issues

Regards
Dazz

Thanks Dazz, I have tried the contrast.
See hex file attached.

Hi Andy
Sorry fell asleep ,ok your hex didn't work so i checked your flowchart and found
the pins had not been set correctly in the i2c properties box, chane the pins in properties to
SCL pin C5
SDA pin C4
see attached images:
first is your flowchart as posted
Second is with pins changed
let us know if this works

Regards
Dazz

Hi Martin!

Sorry Andy. I hav a question to Martin.

When you updated V7, if you look in Flowcode folder you will see three Flowcode exe files: You can see from the file names what versions the flowcode will be if ran the executables, except for That will be .
So seems like you have a shortcut to the wrong executable.

Martin

Hi Martin!
yes, it work. Thank´s again for your always fast and perfect help.

Andy, again sorry for the break, concerning your display. As I wrote earlyer, I am able to compile your program..

Br Jorgen,.

Thanks to all that are helping, I've tried re configuring the pins but still no joy.
