CONTROLLINO Forums

Dear Felix,

it may be caused by other peripherals internally connected to the SPI bus - the RTC chip and the Ethernet chip.
Please make sure that you properly handle the chip select signals for them.

It is enough to call during initialization.

Hello, following interrupts are accessible at the X1: Arduino pin 2 (Arduino Int 0) Arduino pin 3 (Arduino Int 1) Arduino pin 20 (Arduino Int 3) Arduino pin 21 (Arduino Int 2) These interrupts are accessible at the screw terminal: Arduino pin 18 (Arduino Int 5) - CONTROLLINO INT0 Arduino pin 19 (Ard...

Hi, the Serial sends data also to the pin TX / X1. It is the same UART which is forwarded to the USB. But, be careful - when you connect to TX and RX pins on X1 you can have some troubles during sketch upload then. TX2 and RX2 are connected to Serial2. Just use it in the same way like Serial ... Ser...

Hi, to be honest I am more surprised that the first two MEGAs use the same COM port number. Because typically each new device is assigned with a new COM port number. To be precise - this may be configured in the operating system settings - if a new device with the same PID/VID gets the same or a new...

Hi Barty,

I see! The name of that protocol is little bit confusing

I am afraid that is not so easy to run that stuff directly on CONTROLLINO. Because the only library I have found is based on POSIX OS and BSD sockets.

Hello, our Modbus example is only for Modbus RTU - which means Modbus over RS485 serial line. But the ArduinoModbus library should work also over Ethernet. CONTROLLINO MEGA should be compatible to Arduino Mega + Ethernet Shield. Do you have any progress so far? Have you tried to connect to you robot...

Hello,

what do you mean by "IP Master", please? That it will run DHCP server? Or web server? Please note that CONTROLLINO is using WIZnet5100 chip for the Ethernet interface and there are some limitations - e.g. max 4 open sockets etc.

Best regards,
Lukas

I have some news regarding this topic - we have found some potential root cause of these troubles in the original Arduino bootloader.
Please see this tutorial THIS TUTORIAL how to update to the new MINI bootloader.

Note: This is relevant only for MINI!
