Timer API

Starting Timer – main.c

TMP102.H Header File temp_interrupt is a software flag that is set when the interrupt occurs when this flag is set, read the temperature in the main.c

Interrupt Service Routine Clearing Register, Setting a flag Interrupt Service Request (ISR) has been set to TEMPISR vector Read Timer Status Register to clear Interrupt and set the software flag

TMP102 Serial Bus Address

I2C I2C connects to multiple slave devices (e.g. temperature sensor). Each of the slave devices has a unique address To access I2C devices a device address, register address, a number of bytes, buffer pointer have to be specified In the project, use existing PSoC_i2c_read() function to read information from the temperature sensor
