lib15

C/C++ Code library mainly designed to implement useful functionalities in code-size sensitive embedded systems such as STM32.

list:

• libe15_fpa - Fixed Point Arithmetic Library
• libe15-timer - Timer and Delay utility implemented via CMSIS SysTick Timer

Fixed Point Arithmetic Library

libe15_fpa is a library for fixed point arithmetic. some embedded systems does not contain FPU, so it is handy to have a library to complement this.

FOC Control

libe15_foc is a library of functions for implmenting Field Oriented Control.

Timer and Delay

libe15-timer is a set of functions about timer and delay which has better precision than STM32CUBEMX Generated code.

in this lib, sys_delay_ms, sys_delay_us are implemented by reading and configuring SysTick register. config setting is done in libe15-timer.h:14 and libe15-timer.h:17.if same setting is applied as STM32CUBEMX Generated code, function like HAL_Delay can still be used.

to use this library:

• include libe15-timer.h in your code.
• call systick_init() to initialize the timer.
• call systick_timer_isr() in SysTick_Handler() to update the timer.
