Are you ready to graduate from the world of LED blinkies?
If you are… it’s time to spin-up on ‘communication protocols.’
Does this sound familiar?
I only have [ insert remaining pin-count here ] pins and need to transfer [ insert data requirement here ] to [ insert device requirement(s) here ]. HALP!
No worries! Thousands of people have tread the path before you… and you won’t be the last!
The good news is that SPI, I2C, and UART are there to help tame your ratsnest. Here’s a simple comparison between the protocols to get your started; there are pros and cons to each. Building knowledge ( here a little – there a little ) about these key communication protocols is the key to a solid foundation for years of fun / experimentation. Great luck!
