IoT#31 RPTC-Q LTC2984 to ESP32 SPI Code Deep Dive

In this follow up to video #30, LTC2984 Initial Power Up and Repair, we dig into the SPI code we are using in our Espressif ESP32 System on Chip to communicate with our LTC2984 ADC. I will show you all the documents, examples, and websites used to create the SPI code. We will look at the LTC2984 Testbench software and the C code it generates. We will look at the LTC2984 SPI specs in the datasheet. And, we will go over the code and map how the datasheet specs are implemented in the software. Watch video number #30 to see the SPI comm. and LTC2984 in action.

You need to specify the clock rate and mode etc. for each SPI transaction because SPI is a bus that can have multiple devices on it. Each device can operate on a different SPI mode and clock rate.
