Hi,

what do you mean that it doesn´t work? Problem with compilation, or the output is not working? Have you called the pinMode() properly?

Maybe you can share your sketch and more details with us!

Thanks,
Lukas

Hello,

the problem is that we are not able to reproduce it here. Nevrtheless we are trying to solve this issue.

Please, see our FAQ No.10 if you have troubles to upload a sketch.

Thanks,

Hi,

yes, I am afraid that the relays make noise. Nothing you want to have in your bedroom

Hi,

I think that you have done only one small mistake - please try to replace with .

I will try to prepare the setup and test it here also.

Good luck!

Hello Marcel,

you can find the information here

c:\Program Files (x86)\Arduino\hardware\arduino\avr\bootloaders\optiboot\README.TXT

The procedure should be the same for the stk500v2 bootloader (or its clones).

Good luck!

Hello,

please, check our FAQ No.7 at GitHub.

This may be the source of your troubles - you should handle the chip select signals for the Ethernet and RTC in the modified bootloader also.

Hello zal, thank you for the photos. You have really nice screw terminals for the flat cables :) Again - I have checked your setup and do not see any obvious reason why it should not work. Do you have any idea how fast is the communication with the display? Please note that there are some protection...

Good evening,

just a note that similar topic is also discussed here.

Thanks,

Hello, SPI at CONTROLLINO MINI can be used for the RTC OR for the custom peripheral connected to the pinheader, not for both. So your solution and usage of the pin 10 as a slave select signal is correct. But in principle you can use all pinheader pins as digital outputs, even the analog and the inte...

Hello, have you tried the official Arduino Modbus TCP library ? We do not need to write our own library, because the CONTROLLINO is compatible with the Arduino boards - in this case CONTROLLINO MAXI/MEGA = Arduino Mega/Mega2560 + Ethernet Shield (the first version with Wiznet W5100). Please, share w...
