is there a “serial read” node? if there is a way to make one can you help me
A generic “serial read” would probably not be possible since there are so many options for formatting data and performing timing. There are several nodes that implement I2C for specific hardware, which is one serial option. You might be able to modify one of them. There are other serial standards that could be implemented, and there may even be other examples in existing nodes or libraries.
do you know how i could make a serial read node?
