Thanks Leigh,

We can also try this using this C code to see if this makes a difference.

U1CON1 = 0x80;

The CAL code does write to this register on initialise but the reset value should be 0x00 and we just set the ON bit which should be bit 7.

Could be a silicone bug, in fact I'll check the ...

Hmm that's pretty odd indeed.

There is a register that controls the state of the TX pin but it completely flips the signal and the signal looks mostly ok, though not 100% correct.

Our CAL doesn't write to the register in question and the default state should be 0 so again this is very odd.

You ...

I've had a go at the MQTT upgrades and have something here but want it to be tested a bit more before we release it to the update system.

I've implemented the QoS and Clean Start as well as a number of other things.

Have a play and let us know how you get on. I'll try and find some time for some ...

Hi Jay,

For the Port and Pin settings, should I be using the UART hardware pins. Tx C6 Rx C7

Yes that's correct.

I've made a quick change which is to add the interrupt handler. Hopefully this should work correctly now.

Hello Obi100,

I'm not totally sure of your intent here...

Maybe your Developers could not do the work right :mrgreen:

This is clearly a sign of poor software programming. Your application's memory management seems to be stuck in the Windows 95 era.

Make it open source; perhaps others can ...

Hello,

Yes that's been added for you now. The latest version of the component is available from the Help -> Library updates menu now.

Hi Dirk,

Thanks for reporting I'll look into it now for you. Which specific chips have you tested and are you using v10 or v11?

I've been through and checked the 1804Q41, 1805Q41, 1806Q41 devices in V10 and V11 and they are all correctly avoiding the use of PortB for the IOC.

I can't see any ...

Hello All,

Uno R4 Wifi landed on my desk this morning so hopefully I can find a way forward with this ASAP

Hello,

Here is how we do a similar clock speed switch on our dsPIC devices, hopefully helps to show the way.

//Setup configuration for 70MIPs using 7.37MHz internal osc
PLLFBD = 68;// M=70
CLKDIVbits.PLLPOST = 0;// N1=2
CLKDIVbits.PLLPRE = 0;// N2=2
OSCTUN = 23;//Tune FRC oscillator from 7.37Mhz ...

Hello,

How's this? I've tweaked your file slightly and it seems to be working now.
