I am looking at developing a custom programmable logic controller for use with some machines at the place where I work. I would be designing a custom circuit board for this product. What are my options, and what does the community think is the best route to go for the system?
I would want to break out a large amount of the pins on the 100 pin chip including SPI, I2C, CAN bus, and UART ports. How can I access these through software? Each module I have used in the past has it’s own reference for the pins it breaks out. How do I access all of the pins?
