Technical information

CSI to SPI Peripheral Communication in V850ES Microcontrollers

2. void CALL_CSI00_Receive( void ): This routine is called when a reception is complete.

Code was added here to set a flag, CSI11_ReceiveDone, to indicate to the main program that

receive is complete.

The following routines were written and added in serial_user.c; they were not generated by

Applilet.

1. void CSI00_SetType3(void): This routine disables the CSI00 peripheral temporarily, sets the

peripheral for Type-3 operation, and enables the peripheral again.

2. void CSI00_SetType4(void): This routine disables the CSI00 peripheral temporarily, sets the

peripheral for Type-4 operation, and enables the peripheral again.

2.7.8 Files for Temperature Sensor Routines

The following files were written for temperature sensor handling.

2.7.8.1 Temper.h

The header file temper.h contains declarations for the functions for temperature sensor access.

2.7.8.2 Temper.c

The source file temper.c contains the following functions for temperature sensor access:

1. MD_STATUS Temp_Init(void): Initialize temperature sensors and CSI00 serial channel for

access.

2. short Temp_Read_1(void): Read temperature value from temperature sensor 1 (MAX6627),

returns temperature as a signed 16-bit value, of temperature in degrees Centigrade × 128.

3. short Temp_Read_2(void): Read temperature value from temperature sensor 2 (DS1722),

returns temperature as a signed 16-bit value, of temperature in degrees Centigrade × 128.

4. void Temp_Display(short temp); Displays the temperature in the two-digit LED by scrolling

the signed decimal value of the temperature through the digits.
