This article describes a stack data structure to write programs in C on various platforms using a single linked list data structure as a stack data store with examples of the array as storage and test the operation with the microcontroller board LGT8F328P, SAM-D21, ESP8266, ESP32 and ESP32-S2 as shown in Figures 1 and 2. In case of wanting to use with other platforms, you can still modify the code for use such as the same.
