The baud rate is generated by a dedicated baud rate generator. In the EV-Board sample code the baud rate is 9600. Following table describes the LCD library: Function Name Description void UART_init (void) Initialize UART module void UART_sendbyte (char ch) Send data ch by UART __interrupt void UART_REC_INTER(void) Receive data by UART when data is arrived Following table describes how to use these functions. Example Type Operation UART_init(); Send data UART_sendbyte(0x55); Receive data Return Send out data 0x55 by UART Global variable PraGlo.Uart_Rec saved the received data UART_init(); 4.2.9 delay_try Function In this project, some instruction needs to be delayed, so the delay function must be defined before using these C files. Following code is the delay_try function. void delay_try(unsigned char Dat) { unsigned char i,j; for(i=0;i<255;i++) { for(j=0;j<Dat;j++) { __wait_nop(); } } } MCU-AN-500072-E-13 – Page 35 EV BOARD MB2146-450-E V1.3 Chapter 4 Sample Code Manual 4.3 Global Variable Description Five drive files are available in this project shown below, 9 _f2mc8fx.h _f2mc8fx.h is system-defined document. Ignore it 9 mb95310.h Mb95310.h is system-defined document. Ignore it 9 def.h This file basically includes all global variables of FW Following table describes the main struct. 9 Struct Name Description Global Include global variable used between c files RTCPar Include global variable used in time base timer and standby EepPra Include global variable used in I2C module BlinkPra Include global variable used in six LEDs Key.h This file includes eight key names, which are “UP”, “DOWN”, “RIGHT”, “LEFT”, “SEND”, “CONFIRM”, “MODE” and “USER”. 9 Proc.h This file includes all functions which will be used in other functions. MCU-AN-500072-E-13 – Page 36 EV BOARD MB2146-450-E V1.3 Chapter 4 Sample Code Manual 4.4 How to Add These Files Before using chapter4.2 file, please refer to the following steps. ¾ Create a new project. ¾ Copy .c file to project document. ¾ Add .c file to project. ¾ Add all needed .c files to project. 4.5 Usage Demo Following table is an example on how to use this C file. Process_Control() is a user-defined function which transfers the C file of ADC when user wants to use ADC, the C file of I2C when the user wants to use I2C, and the C file of RTC when the user wants to use RTC. ADC0_Init(); // initialize ADC UART_init(); // initialize UART EXT_Init(); // initialize Interrupt Init_LCD(); // initialize LCD TBT_Init(); // initialize Timebase timer Init_EEProm(); // initialize EEPROM while(1) { ADCTempSwitKey(); // Judge key value Process_Control(); // transfer every library LCD_LigON_NUM(0,2); // display LCD } MCU-AN-500072-E-13 – Page 37 EV BOARD MB2146-450-E V1.3 Chapter 5 Development Platform Quick Start 5 Development Platform Quick Start 5.1 Tools Setup Sequence Start the debugging system in the following sequence: 9 Connect a BGMA to the PC with a USB cable, confirm whether the LED on the BGMA is green; 9 Connect an EV-board to BGMA IDC10 socket; 9 Select the EV-board power supply and turn on the EV-board, confirm whether the LED on the BGMA is orange and the Power LED on the EV-board is on. 5.2 Open Project and Start Debug Users can start a debug from a PC software SOFTUNE workbench in the following sequence. Take SIMULATE LCD EVBOARD project as an example. 9 Start the SOFTUNE by selecting Programs> SOFTUNE V3> FFMC-8L Family SOFTUNE Workbench from Start Menu; 9 Click Open workspace from File Menu in SOFTUNE; 9 Select SIMULATE LCD EVBOARD.wsp in Open Space window; 9 Click Start debug from Debug Menu. If the entire procedure goes right, a debug will start normally. 5.3 Operation Precautions 9 All pins of MB95F310 Series MCU are connected to Testing Pin on the EV-board. If user wants to test the performance of a single pin, please connect it to the test pin. 9 Note: before connecting with BGMA, do not power on system. 9 It’s recommended that only one power supply is used as a power module input at a time.
