Detailed Description

ESOS application program to demonstrate I2C mastering in ESOS. Application recreates code in ds1631_i2c.c in Figure 10.52. (See Figure 10.49 in the text for circuit.)

Application also has a flashing LED on RB15. Flashing LED is generated by an software timer calling a user-provided callback function.

Note:

Demonstrates child tasks, ESOS software timers, and I2C service

Function Documentation

void user_init

(

void

)

User-provided function to initialize user's hardware configuration register user tasks.

Note:

All ESOS applications MUST provide this function.

This function MUST register at least one ESOS task.

user_init() is a centralized initialization routine where the user can setup their application. It is called automagically by ES_OS during the operating system initialization.

User should set up any state machines and init all application variables. They can also turn on any needed peripherals here.

User shall not mess with the interrupt hardware directly!!! The ESOS must be aware of the interrupts and provides esos_XXXXXXX functions for the user to use. Using these ESOS-provided functions, the user may (and probably should) initialize, register, and enable interrupts in this routine.

Furthermore, the user should register AT LEAST one user application task here via esos_RegisterTask or the ES_OS scheduler will have nothing to schedule to run when this function returns.
