So i pretty much got the PCB designed, but stumpled upon couple of things i'm not so sure about and would like to get some input about.
So first one, The OE pin of TXB0102 Should it be driven by levels of VCCA or VCCB? or does it even matter, the best for me would be if i'm able to drive it via VCCB.
second one, this is in series of stupid questions to be honest, How do i calculate RC values? Or Could i just go and use only pull-up on the reset pin, then reset via SPI since its suggested that only HW or SW reset is needed.
third one, Does the connection look allright? like usually one would reverse TXD/RXD for uart, but ii dont think that applies here with CAN?
Still need to figure if i'm able to somehow run the MCP2561 standby pin via MCP2515, after all its coming to a car and run by constant power line.
