Esp32 is already dual core. Using io expander is sensible option. If u have to use 2 esp32 just for io expansion then you should reevaluate the design

Excellent presentation

[@albertof2675]

Awesome explanatios, as always!! I just love to see the bell notification to see a new Schematix video!
Would you consider adding a checksum or similar approach to make sure the received message does not contain any transmission errors?

[@Schematix]

I'm glad you enjoyed it. Absolutely you could add checksum to the logic and ignore bad transmission data if needed

[@3DLearningResources]

you looks fit from previous videos!

[@lor3npingpong371]

woow very useful

I've got a project I'm working on, where the ESP32 is listening to the CANbus, and has to update a TFT screen. This dual-ESP setup would be a great way of speeding up CAN communications, thankyou! :D

[@startobytes]

good idea, but i would send shorter meassages and add PWM functions to it.

[@thxsound]

Can you do some stuff on speakers, what increases the wattage or the ohms, what gives the bandwidth 20hz to 20khz how to make a speaker

[@jomfawad9255]

Can i still have the complete code of controling the motors and sensors on the same esp32 and use the other esp32 only for its pins? meaning without splitting the code

[@nteves1]

this looks like a task that a single esp32 could handle with ease, why were the 2 cores, or even a single core version of the esp not enough ?
