The STM8S Firmware Library is a complete package, consisting of device drivers for all of the standard device peripherals, for the Performance and the Access line STM8S20x and STM8S10x 8-bit Flash microcontrollers. This library is a firmware package which contains a collection of routines, data structures and macros covering the features of STM8 peripherals. It includes a description of the device drivers plus a set of examples for each peripheral. The firmware library allows any device to be used in the user application without the need for in-depth study of each peripheral’s specifications. Using the firmware library has two advantages: It saves significant time that would otherwise be spent in coding, while simultaneously reducing application development and integration costs.
