any help appreciated

When connecting to an external display i need to send a text string faster to a Diablo 4D systems display.

at the moment the coms on both host (arm F7) is set 115200 (on the Diablo the max speed is 600,000) anything above this speed the host will not communicate if a custom ...

Hi

Is there a way to change the c code that is generated for the Visi4D component i see from the view C in build that the VisiReceive says if a 0x06 is returned this then equals 0 but anything else equals 255.

When you send a object to the display it sends an acknowledgment back of 0x06 this is ...

Perfect thank you!!!

Great example.

No sure if this is something I’m missing please advise

In flowcode 8 when setting a return as a byte I then have the options (when clicking edit) to add an array to the .return once I assign for example [2] click ok no errors but when I come to use the return var I get an error. The error is saying ...

I’m getting no support on this subject the visi recive object is not always working / stops working altogether to receive the data from the display to give no ack back to the display or nak.

The issue above was due to to many visiReceve if statements create one and it stops the missing of ...

If I purchase a pack for flowcode 8 that I do not have for flowcode 7 will flowcode 7 then have this pack available to use.

Arm pack to be specific.
Thanks

Ok not sure why but very strange that i start a simulation to check all again then write back to the F746 and now i see a ACK

Back to the issue i was trying to sort out im getting slow or no ACK to the MCU using VisiD1 object the more code i add the slower it appears
Any ideas why please (i have ...

Been using the Visi4D component no code changes and suddenly (was working) i get no ACK from a onscreen userButton i can update digits for example i also see a new function within the component ChangeHWBaud

As anything else changed to stop this function working as expected and was functioning.

Is there any help on this subject please i have now switched from the Arduino to the nucleo-144 f746zg to see if this was a speed issue.

I am still getting slow acknowledgments from the MCU to the display and it gets worse the more code added within flowcode.
I do not get a NAK or ACK back ...

Thank you.

setting the re-map pins to anything and setting the clock and data lines to suitable pins worked..

Thank you, just tested but no luck no matter what setting i choose i still miss the top half of the ic when selecting the pins for the 32F746 i see from pin 9 downwards arduino mega is fine its square shaped when selecting the pins this one for some reason is shaped as a dil packaged ic but in ...

Thank you.

If i connect a second display (4k tv) and use as a second monitor drag the properties over to the second screen i see all the pins but not on the laptop with a resolution of 1366 x 768

Hi

Thank you for your reply, no scope sorry to check the pins.

Yes the board works fine i am talking to a Visi 4d display through its channel 1 and setup as you say to first prove out the new board was flash onboard led's that's ok.

I will check this delay later when i get back and update.
Thank ...

been using flowcode 8 but instead of using the arduino testing out st-arm nucleo-f746zg

With the code working on the arduino and a channel to select from within the properties all is good for the arduino i just connect to the pins flowcode says.

But when i select the new chip F746 i only have the ...

maybe this is something i'm missing.

I do not see all the chip pins.

When i try to select a pin i see the bottom half of the chip
When i click view / chip i see the top half

i'm using ARM NUCLEO-144 F746ZG

Update checked flowcode 7 and it’s the same
But connected to 4K tv and I can see all the ...

Just installed the 30day version of flowcode 8 tried to compile hex for Arm but i have an error of "arm compiler toolchain is not installed" is there a 3rd party compiler i need to install please.

Thanks.

Hi

If i only choose some of the components for flowcode 8 when i've purchased will i still be able to upgrade other components at a latter date for the discounted upgrade price or will these then be full price (providing i had already purchased in Flowcode7)

Thanks

Just one more question please

I also need to get the arm pack for flowcode 7 (a different project) but as you know flowcode 8 will be released in the coming days and I guess I will also need to buy the pack for that I plan on upgrading to flowcode 8 on release but if I purchase the pack ...

For the new component coming in flowcode 8 is the BL0036 board required to program the PI board.

Thank you.

Any news please.

I’ve been doing a little reasearch and found this

d) Ensure you have the Reset Code in your sketch, for the Arduino to reset the Display Module at startup, so the display and Arduino are in sync and both are in a known state. Without this code, your program may not work at all ...

Thank you.

Thanks Ben will get this uploaded now to view

The display i've noticed performs fast and well and a fast redraw of a full screen, that's why it led me to believe the bottle neck was the Arduino, will show you what i mean it will show the display responses to a down press of the user button (by ...

Hello

I'm after a little advice if i can please i have set up a short program that uses the diablo 4d systems touch screen in the main page all i have done is initialise the display then created a loop, within the loop i have created two macros

The 1st macro reads an external eeprom (i have also ...

Hi Ben

Thanks for the answer this project the eeprom i'm using is a 24LC512.

Cheers

is there a way please to change and view the bytes in the console for the serial_eeprom i can do this and see the data from eeprom1 but nothing for serial_eeprom i'm sure this was possible in previous version to 7 in simulation.

thanks.
