Hello,

do you have the latest version (3.1.0) of the CONTROLLINO board support package?

Please post here more information from the Arduino IDE verbose output.

DC motor control with doubled outputs

CONTROLLINO MEGA offers 12 outputs driven by Half-bridges. These outputs may be used to run the DC motor directly. As all these outputs also support PWM, the speed of the motor can be controlled by standard Arduino function AnalogWrite. But - what if the maximum current defined for one CONTROLLINO o...

Re: Johnny Five (Javascript)

Hi,

yes, it should work.

Based on http://johnny-five.io/platform-support/ they supports Arduino UNO (compatible with CONTROLLINO MINI) and Arduino MEGA (compatible with CONTROLLINO MAXI and MEGA).

Just let us know, if you find any issues.

Thanks,
Lukas

Re: Modbus RTU Controllino Maxi Pure RS485

Hello, have you tried to run the Modbus RTU communication with your slave device from PC? It is always good (and recommended) first step - just take a RS485 USB adapter, use some free Modbus RTP Master application and try to run the Modbus communication with this setup. Then you are sure that everyt...

Proper usage of RTC

Permanent (or very often) polling of the RTC chip causes drift of the RTC internal clock. It may slow down the "real time" for several seconds per day! The reason is that the RTC chip stops its internal clock counter during the SPI communication between the main processor and the RTC chip (to be abl...

Re: Filing "Boardverwalter-URL" locally

Hello, thanks for the explanation. Now I understand! I do not think that it is possible to install complete machine including all environments locally and be able to have the machine in the same shape like the "frozen one". If you need a backup for a case of (SW) system crash, then you should use a ...

Re: OTA firmware upload

Thanks for the video. We will investigate it.

So, what have you done before? Flashed a new bootloader to Atmega2560?

Thanks,

Re: 3-Wire RS232 MAXI Automation

Hello, MAXI Automation has no RS485 or RS232 interface. It has only 5V UART interface on the pin header. So you need an external UART to RS232 converter. Standard MAXI and MEGA CONTROLLINOs have RS485 interface at the screw terminal. There you will need RS485 to RS232 converter. Best regards, Lukas
