Hello, Hex is just a good way of showing binary numbers, so no need to convert to ascii you can simply send the hex data. On the MCU there is no distinction between decimal or binary or hex, it's all just binary. The various number systems are there to help you interact with the machine easier. For ...

Hello,

Here is my test project.

Slave is running on an Arduino Uno and the master is running in the Flowcode sim.

That looks great, are you able to program the screen? Do we need a new component for it?

I've just bought myself one and also got a couple more M5 boards. Unfortunatley they look like they might take a while to get here.

Could maybe be that led pin being in the different style? Shouldn't cause an issue but you never know. That's the only thing jumping out to me.

Hello, The only blocking code I can spot in the CAN initialise for the PIC32 is here, // Set to operating (normal) mode C1CONbits.REQOP = REQOP_NORMAL; while(C1CONbits.OPMOD != REQOP_NORMAL); You could double check if this is causing the problem by commenting out the while // Set to operating (norma...

Hello, Right I've spent the last two days on this and managed to get it so it's now working correctly and reliably. It looks like in the end what made it work was a tiny delay in just the right part of the code. I still want to spend more time on adding DHCP and DNS but for now it at least (fingers ...

Please can you send us a link to the specific board you're using.

Looks for devices like this to do comms back to the PC would require a USB component. Might not be too hard thanks to the IDF so I'll get it on the list.

Hello Stefan,

On your IDF v5.1 machine please can you try doing a full clean compile by deleting the build files folder from your Flowcode project directory. Just to see if that makes a difference at all.

Hello,

Looking now. I have the module in front of me and am doing a big overhaul to it to try and get it working properly for Modbus TCP and to add functions like DHCP and DNS lookup. I'll let you know how I get on.

We've replicated the issue in IDF version 4.4 but not in v5.1. As the S3 wasn't really supported in 4.4 I think this is to be expected.

Please can you send us the .msg.txt file from your IDF v5.1 compilation and we'll try and investigate further but always tricky when we can't replicate the issue.
