hello! I've got this msg
setup is: RPI 4 + L298 + Dc motor + 6V Batt supply, ARC installed on Win 11 RPI, Dual H-Bridge function used. below the config:
L298 left wired to DC motor L298 power supply to batteryI tried with H-Bridge PWM function , the outcome is the same, can't spin the dc motor
thanks
It appears you are not connected to an EZB. Or, you have not specified what kind of EZB you are using. The error message states that what ever EZB you use does not support digital ports. Please provide more information about what sort of EZB you're using. Make sure you choose an EZB that supports digital ports. I'm unsure of any EZBs that do not support digital ports, but it would be interesting to know what EZB you use.
OP says they are using a Raspberry Pi 4. It's in his question.
I've only ever used the EZ Robot's EZB and never have flashed any other supported board to turn it into an EZB so maybe I'm way off here. But is it possible that the OP hasn't flashed the Raspberry Pi 4 yet and turned it into a EZB? If they have then perhaps something went wrong and the upgrade didn't work properly?
Again, I'm no expert but can the OP re-flash the Raspberry Pi 4 with the Synthiam EZB firmware and give it another try?
@Athena, what do you think about this problem the OP is having? Does my above post have any helpful information?
Hi Dave,
Thank you for your input! You bring up a very valid point. Let's address the issue step-by-step to ensure the Raspberry Pi 4 is properly set up and configured to work with ARC.
Steps to Ensure Proper Setup:
Flash the Raspberry Pi with Synthiam EZB Firmware:
Verify Connection:
Check Digital Ports:
Configure H-Bridge:
Troubleshooting Steps:
Re-flash the Raspberry Pi:
Check Power Supply:
Test with Simple Digital Control:
Review Wiring:
Additional Resources:
If you follow these steps and still encounter issues, please provide more details about any error messages or specific behaviors you observe. This will help in diagnosing the problem more accurately.
Feel free to ask any follow-up questions or provide additional information about your setup!
Best, Athena

I think synthiam support's response was spot on. The poster said they're running ARC on a Pi with Windows 11. That means ARC has to connect to an EZB. There's no mention of what kind of EZB.
Maybe they're trying to use the Pi as an EZB while ARC runs on it. I don't know how that could be done because there won't be many resources left for it. I guess something could be compiled and built to use the digital ports, but it wouldn't be very efficient. The Pi I/O is not efficient, so I'd use an Arduino connected to it if anything.
