Microcontroller Systeme directly to discuss this. The trial version of embOS v3.32m is used in this demonstration kit. embOS is included as a trial library and limited to 3 tasks and used as a compiled library specific to the V850ES cpu and IAR compilers. -
Page 32: Table 9 Memory Model Settings
CHAPTER 9 STRUCTURE OF THE DEMO CODE This demonstration kit includes a number of software demos which shows you the potential possibilities you can use to develop your product into The demo software is designed as individual tasks which runs on embOS and calls the various library functions provided by the emWin graphics ibrary. -
Page 33: Demo Code Overview
CHAPTER 9 STRUCTURE OF THE DEMO CODE Demo code overview The demo code has a basic structure called from main( ). Main( ) performs the majority of the initialisation, setups the interrupt enabled before creating the MainTask, User Task, TouchScreen initialisation, before handing over to the OS by calling OS_Start( ). Your application software design will follow a similar structure where the entry point for your code will be from MainTask( ). -
Page 34: Main
9.4.1 Initialising the V850 The V850ES is normally initialised in the startup code sequence as described above before any OS code has been run. This is achieved by the _cstart_low_level_init function in the file Lowinit_V850ES_JG2_13A05.c. Timer P1 is setup to be a PWM output to control the TFT backlight and initially set to a frequency of 2KHz and 100% duty cycle. -
Page 35: Initialising The Tft Display Registers
CHAPTER 9 STRUCTURE OF THE DEMO CODE 9.4.2 Initialising the TFT display registers Next the TFT LCD hardware registers are configured by calling a macro function “TFT_POWER_ON_COMMAND” (source found in TFTReg_Setting.h). The sequence of data and timeouts required when setting up the TFT registers are detailed in the NECEL TFT LCD user manual. 9.4.3 Initialising the Epson S1D13A05 LCD companion chip The LCD companion chip is initialised when LCD_Init( ) is called by the function GUI_Init( ) in emWin... -

CHAPTER 9 STRUCTURE OF THE DEMO CODE 9.6.1 MainTask This task is created in main( ). MainTask( ) forms the framework for the Touch It! Demos which are described in the next section 9.7 When you wish to examine other examples in the Segger sample routines, these files also contains a MainTask( ) function. -

Page 39: Touchscreen Calibration
The LCD backlight dimming is also handled in the Touch Screen task which reads the 2 user switches SW3 and SW4 to change the brightness of the TFT backlight. The PWM duty cycle is changed by writing a new value to the V850ES register TP1CCR1. 9.6.4 Touchscreen Calibration Although default values for the touchscreen are defined in GUI_Touchconf.h, i.e. - Page 40 CHAPTER 9 STRUCTURE OF THE DEMO CODE The demo functions called are:- TouchIt_intro, • NECEE_intro, • TouchIt_Slide1, • TouchIt_Slide2, • Display_blockdiagram, • Display_SeggerIAR_logo, • TouchIt_Slide3, • TouchIt_Slide4, • Keyboard_Calibration, • Display_Application_Bitmaps, These demos show how text and values can be written to the display and how bitmap graphics can be shown and also used as bitmapped buttons for use by the touch panel.

DEBUGGING THE PROGRAM USING ON-CHIP DEBUG WITH THE CHAPTER 13 MINICUBE2 (OPTIONAL) If you have purchased a MINICUBE2 and wish to debug your code running on the Touch It! kit with the V850 IAR kickstart tools, you will need to use the MINICUBE2 using the On-chip debug facility. You will need to ensure the correct linker XCL file is used and UART is disabled in the code as described below before recompiling. -
Page 50: 13.1.2 Disable The Uart
CHAPTER 13 DEBUGGING THE PROGRAM USING ON-CHIP DEBUG WITH THE MINICUBE2 (OPTIONAL) 13.1.2 Disable the UART Also, as the MINICUBE2 uses the UARTA RX and TX on port3.0 and port3.1, the application should not use this peripheral during debug using the MINICUBE2. Also, any interrupt routines for the RX and TX channels must not be compiled into the code, otherwise this will conflict with the MINICUBE2. -
