System Watchdog
Hi, I am using a Revpi Core connected to a Revpi DIO Module and I would like to set the system to reboot after certain time when it notices that the running code hangs on or when due to unknown problems it fails to execute. I read in the forum that this is possible from with the hardware watchdog im...

Re: RevPi DIO output control
I recently tried to print(bits_in) and I get 255 meaning all the bits are high. But I am triggering only the input pin_4 and expecting all the other pins to be low. Did I mess something or should the pictory configuration be somehow resset? For the inputs I connected the ground on the input ground o...

Re: RevPi DIO output control
From the python, when input pin_4 is connected to power supply I expect the output pin_4 to be triggered and generate pulses, but it does not work so, the code runs down to the 'else condition' Here is here the picture my hardware connection and the power supply to input pin_4. Is there any presetti...

Re: RevPi DIO output control
Hello, Regarding my previous question I got it to work as I wished, thanks. Now I would like to ask another question regarding the input pins from Pictory. I'm trying to trigger some commands on Python based on the state of the input pins. In GPIO of normal raspberry pi this is easily done by just i...

Re: RevPi DIO output control
Hi, Thanks for your reply! I am using a RevPi Core with a single DIO module. I am trying to generate PWM-like pulses which will be used by another device for decoding specific commands. The first time I logged into Pictory there was no module in it, but a blank "0" space where I dragged th...

RevPi DIO output control
I am trying to trigger pwm pulses with a frequency of 2.5Hz but just found that on pictory it is only possible for a certain number of frequency values (40Hz being the lowest possible value). Then I wrote a simple python script in order to switch the output pins ON and OFF with certain time sleep. H...
