描述
The MAXREFDES9007 is a reference design that showcases the DS28E36 and demonstrates how to implement a simple 1-Wire® master using only a microcontroller’s GPIO pins. The reference design provides a GPIO-based 1-Wire library designed for an Arm® Cortex® M4 microcontroller, such as the MAX32660, with example programs that run the main 1-Wire sequences and calculate how much time it takes for each to run. This design also provides the amount of memory required to store such programs.
