MIAC USB Firmware Project

[p.erasmus]

Hi Team.

In V8 totally working well the MIAC USB Slave Firmware project look like below in the 2D panel

In V9 the same components are on the 3D panel and some SPI and API stuff on the 2D panel

(1)What is this components on the 2D panel .
(2) You guys has made many changes to the SPI and I2C layers is the CAN SPI in the MIAC still working as before or has some stuff changed,I am asking because I need to do a MAIC project fast and if there is issues with this in V9 then I stay on V8 .

At the Moment I am reluctant to use V9 as things change rapidly nobody know what changed and working code stop to work ,as the SACDA SPI and I2C with UNO .

As always great-full for your help.

Thanks for the post, Peter. There are 2 things going on here.

1) If projects stop working due to a component update then please let us know and we'll try to fix this as soon as we can.

2) We are currently making changes to improve the look of many of our components. Unfortunately, this will force certain components to look correct only on the 2d panel as the 3d panel will not support these new visual improvements. If your project is already on the 2d panel then there should be no problem for you and the project should look ok. However, if the project is on the 3d panel then certain parts of the new components may appear on the 2d panel and this is what you are seeing in your project.

Although there may be some visual problems with your project, it should compile and simulate correctly. If it doesn't, please let us know and we'll investigate.

And if you want assistance moving your project to the 2d panel, we will be able to help with that.

Regards,
Steve.

Hi Steve.

Thanks a lot for the info ,
I always use the 2D panel however this project is the one from Matrix for MAIC USB Slave it comes from Matrix with the components on 3d panel , I will move them with your comments.I just check it compiles fine I will give it a go asap

I always appreciate the support we get from you guys However there is a problem with SCADA UNO SPI and I2C and it not only me suffering with this
Martin(mnf) has similar/same issue ,Would appreciate a working example for SPI as I am stuck with SPI urgently and reading a digital input pin also does not work for me and I have a feeling martin also mentioned it some where in the forum.

I do understand you guys are very busy and appreciate any help always

Regards
Peter

Hi All.

Thank you Steve for your advices !
I compiled and run the Matrix MIAC USB Slave FC project in V9 no issues found then progammed a MIAC unit and connected it to LabView and running 100%.
Again all support always appreciated.

Question to Ben,
The dll is a bit old for labview it is working well in 2013/2014 LabView .would it be possible to maybe update the dll that people can use Miac with
LabView 2020 as there is now a full free community version,which you can use to update the dll.
If there is a possibily I can try to run my various Miac /Labview projects in LV2020 and see if they are working. You might recall in 2018 we had the issue that the dll can handle only 32 bytes of data transmission and receiving this is a limitation and a lot of work around needed for bigger project using Miac.This would be very nice if we could upgrade the dll .
For now I am using 2014 but it get's a bit old and the customers are looking for more recent LV projects.

If you think there is a chance of doing this(I am aware you guys are focusing on APP devloper for this type of things but APP developer is a long way off from LabView and difficult to use in an industries enviroment as it is now) I can spend time on trying my projects in LV2020.

Have a good Time

Hi Ben.

I have just run the Miac and LabView 2020 all works as before ,
thats a good so I am back at asking if you could look into the transaction number 32 bytes is max I can receive over the dll
Not sure if it is the dll or a PIC firmware issue .

Thanks again for all your help

This project was created in LV2013 the used it in LV2014 and now in LV2020 with Miac usb slave

Hello,

I've posted a newly compiled version to the wiki and I've checked that te data transfer descriptors are now set to 64-bytes.
