Timer: Datasheet Access

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

Interrupt Service Routine: Datasheet Access

Interrupt Service Routine API

Interrupt Service Routine Function Description: ISR_Start

Interrupt Service Routine Function Description: ISR_SetVector

Interrupt Service Routine Initializing Interrupt

Set the Interrupt Vector : ISR_SetVector(…)

Conversion Rate Time

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
