Vinco uses a VNC2-64Q package to facilitate 38 GPIO options on 0.1” pitch sockets. Vinco is designed as a prototyping platform for VNC2 based designs and applications. This application note describes an example of how to use the Vinco module to create and display graphic messages on a 128 x 64 pixel monochrome LCD display. The application note also provides “C” source code examples to help the user get started with their own specific application. This source code can be downloaded from the FTDI website at: http://ftdichip.com/Support/SoftwareExamples/VinculumIIProjects/Vinco_GLCD_SPI.zip Note: Any sample code provided in this note is for illustration purposes and is not guaranteed or supported. Figure 1.1 - VINCO 1.1 VNC2 Devices VNC2 is the second of FTDI’s Vinculum family of embedded dual USB host controller devices. The VNC2 device provides USB Host interfacing capability for a variety of different USB device classes including support for BOMS (bulk only mass storage), Printer and HID (human interface devices). For mass storage devices such as USB Flash drives, VNC2 transparently handles the FAT file structure. Communication with non USB devices, such as a low cost microcontroller, is accomplished via either UART, SPI or parallel FIFO interfaces. VNC2 provides a new, cost effective solution for providing USB Host capability into products that previously did not have the hardware resources available. VNC2 allows customers to develop their own firmware using the Vinculum II software development tool suite. These development tools provide compiler, assembler, linker and debugger tools complete within an integrated development environment (IDE). The Vinculum-II VNC2 family of devices are available in Pb-free (RoHS compliant) 32-lead LQFP, 32-lead QFN, 48-lead LQFP, 48-lead QFN, 64-Lead LQFP and 64-lead QFN packages For more information on the ICs refer to http://www.ftdichip.com/Products/ICs/VNC2.htm Copyright © 2010 Future Technology Devices International Limited 1 Document Reference No.: FT_000363 AN_161 Vinco Graphics Display Example Version 2.0 ` Clearance No.: FTDI# 190 1.2 Topway LCD Display This application example uses the Topway LM6059BCW 128 x 64 pixel monochrome LCD display mounted on a Vinulo_Proto prototypeing PCB. The LCD display is driven by a 3V3 power supply and 5 data / control lines. The data is clocked into the module serially.

To ensure this power source is routed to the PCB, JP1 on the Vinco module must be set to the 2-3 position. Power from the Vinco module is taken from J1 pin 4 to give a +3V3 supply for the Topway LCD display. 3.2 LCD Control The Topway LCD display may be controlled in either a synchronous serial data mode or an 8-bit data mode. This application uses the serial mode. The signals defined in the block diagram in section 2 are described in Table 3.1. Signal Function /CS1 Active low chip select for the LCD module /RES Active low reset for the LCD module Register select for the LCD module. A0 0 = Display data 1 = Control data SCL Serial clock input to LCD module. SI Serial data input to LCD module. BLA Positive supply for LCD Backlight.

The debug interface can be accessed by connecting a VNC2_Debug_Module (http://www.ftdichip.com/Support/Documents/DataSheets/ICs/DS_Vinculum-II.pdf ) to the J8 connector. This debug module gives access to the debugger through a USB connection to a PC via the Integrated Development Environment (IDE). The IDE is a graphical interface to the VNC2 software development tool-chain and gives the following debug capabilities through the debugger interface: Flash Erase, Write and Program. Application debug - application code can have breakpoints, be single stepped and can be halted. Detailed internal debug - memory and register read/write access. The IDE may be downloaded, free of charge, from http://www.ftdichip.com/Firmware/V2TC/VNC2toolchain.htm The Debugger Interface, and how to use it, is further described in the following applications Note Vinculum-II Debug Interface Description 3.3.1 Signal Description - Debugger Interface Table 3.2 shows the signals and pins description for the Debugger Interface pin header J8 Name Pin No. Name On PCB Type Description J8-1 IO0 DBG I/O Debugger Interface - [Key] - Not connected.

This section gives some example source code, and explains its operation, used to drive the LCD display via the Vinco module. Note the full project can be downloaded from: http://ftdichip.com/Support/SoftwareExamples/VinculumIIProjects.htm 4.1 VNC2 Initialisation When generating firmware for VNC2, the first steps are to enable the Vinculum Operating System (VOS), which controls the VNC2 services and device manager, defines the clock speed the core will use, and defines the VNC2 pins that will be used. This is done in the function labelled main. The “main” function for this application is shown as follows void main(void) { // GPIO context structure gpio_context_t gpioCtx; // SPI Master context structure spimaster_context_t spimCtx; // call VOS initialisation routines vos_init(10, VOS_TICK_INTERVAL, NUMBER_OF_DEVICES); vos_set_clock_frequency(VOS_48MHZ_CLOCK_FREQUENCY); // Setup IOMUX // Control port = GPIO PORT_B vos_iomux_define_output(63,IOMUX_OUT_GPIO_PORT_B_2); // PortB_2->LCD_RST# vos_iomux_define_output(13,IOMUX_OUT_GPIO_PORT_B_6); // PortB_6->LCD_A0 // SPI pins vos_iomux_define_output(14,IOMUX_OUT_SPI_MASTER_CS_0); // LCD_CS# vos_iomux_define_output(15,IOMUX_OUT_SPI_MASTER_CLK); // LCD_CLK vos_iomux_define_output(16,IOMUX_OUT_SPI_MASTER_MOSI); // LCD_SDI // initialise device drivers spimCtx.buffer_size = VOS_BUFFER_SIZE_128_BYTES; spimaster_init(VOS_DEV_SPIM,&spimCtx); gpioCtx.port_identifier = GPIO_PORT_B; gpio_init(VOS_DEV_GPIOB,&gpioCtx); // create threads for firmware application (no parameters) tcbFirmware = vos_create_thread(29, SIZEOF_THREAD_MEMORY, firmware, 0); // start VOS scheduler vos_start_scheduler(); Copyright © 2010 Future Technology Devices International Limited 7 Document Reference No.: FT_000363 AN_161 Vinco Graphics Display Example Version 2.0 ` Clearance No.: FTDI# 190 main_loop: goto main_loop; } Note: Starting the VOS scheduler is always the last thing to be done as all configuration must be complete before this starts. 4.2 LCD Initialisation The LCD must be put into an initial known state to be able to accept new data and this initialisation is done in the lcd_ini function. void lcd_ini(void) { unsigned char data_byte; // Hardware reset data_byte = (0xFF&(~LCD_RST)); vos_dev_write(hGpioB,&data_byte,1,NULL); // LCD Reset line - low vos_delay_msecs(5); data_byte = (data_byte|LCD_RST); vos_dev_write(hGpioB,&data_byte,1,NULL); // LCD Reset line - high vos_delay_msecs(5); cmd_buffer[0] = CMD_DISP_SET_BIAS; // Send 'Set Bias' command cmd_buffer[1] = CMD_DISP_SCANDIR; // Send 'ADC Normal' command cmd_buffer[2] = CMD_DISP_REV|0x08; // Send 'Flip on Y' command cmd_buffer[3] = CMD_DISP_LINE_ADDR; // Send 'Line addr = 0' command write_lcd_cmd(cmd_buffer, 4); cmd_buffer[0] = CMD_DISP_PWRCTRL|LCD_VCNV; // Send 'Power Ctrl' command write_lcd_cmd(cmd_buffer, 1); vos_delay_msecs(50); cmd_buffer[0] = cmd_buffer[0]|LCD_VREG; write_lcd_cmd(cmd_buffer, 1); vos_delay_msecs(50); cmd_buffer[0] = cmd_buffer[0]|LCD_VFOL; write_lcd_cmd(cmd_buffer, 1); vos_delay_msecs(50); cmd_buffer[0] = CMD_DISP_VREG_RES_RATIO|0x06; // Send 'Regulator Resistor Select' command cmd_buffer[1] = CMD_DISP_EVOLUME_MODE; // Send 'Set Reference Voltage' command cmd_buffer[2] = LCD_EVOLUME_VALUE; cmd_buffer[3] = CMD_DISP_ON; // Send 'Display On' command Copyright © 2010 Future Technology Devices International Limited 8 Document Reference No.: FT_000363 AN_161 Vinco Graphics Display Example Version 2.0 ` Clearance No.: FTDI# 190 write_lcd_cmd(cmd_buffer, 4); vos_delay_msecs(50); lcd_clear(); SetPageAddress(0); SetColumnAddress(0); SetLineAddress(0); } The data values which can be sent to the LCD are defined in the LCD user manual. The write_lcd_cmd(cmd_buffer, 1);) is an instruction to call the write_LCD_cmd function so that data may be is moved from the VNC2 to the LCD over the VNC2 SPI interface. 4.3 Writing Command Instructions to the LCD void write_lcd_cmd(unsigned char *cmd, unsigned char len) { unsigned char ctrl_byte; ctrl_byte = (~LCD_A0)|LCD_RST; vos_dev_write(hGpioB,&ctrl_byte,1,NULL); // Set A0 and RESET line high spim_iocb.ioctl_code = VOS_IOCTL_SPI_MASTER_SS_0; spim_iocb.set.param = SPI_MASTER_SS_ENABLE; vos_dev_ioctl(hSPIm,&spim_iocb); vos_dev_write(hSPIm, cmd, (len&0x00FF), NULL); spim_iocb.ioctl_code = VOS_IOCTL_SPI_MASTER_SS_0; spim_iocb.set.param = SPI_MASTER_SS_DISABLE; vos_dev_ioctl(hSPIm,&spim_iocb); } vos_dev_write is a VOS defined command for writing out data. The hGPIO is the handle for the GPIO driver that is used to control the A0 and RESET pins of the LCD. The hSPIm is the handle for the SPI master driver that is used to send the clocked serial data to the LCD display . 4.4 Writing Data Bytes to the LCD Display The main difference with writing data to the LCD as opposed to commands is the state of the A0 pin controlled by the VNC2 GPIO. void write_lcd_data(unsigned char *data, unsigned char len) { unsigned char ctrl_byte; ctrl_byte = LCD_A0|LCD_RST; Copyright © 2010 Future Technology Devices International Limited 9 Document Reference No.: FT_000363 AN_161 Vinco Graphics Display Example Version 2.0 ` Clearance No.: FTDI# 190 vos_dev_write(hGpioB,&ctrl_byte,1,NULL); // Set A0 low and RESET line high spim_iocb.ioctl_code = VOS_IOCTL_SPI_MASTER_SS_0; spim_iocb.set.param = SPI_MASTER_SS_ENABLE; vos_dev_ioctl(hSPIm,&spim_iocb); vos_dev_write(hSPIm, data, (len&0x00FF), NULL); spim_iocb.ioctl_code = VOS_IOCTL_SPI_MASTER_SS_0; spim_iocb.set.param = SPI_MASTER_SS_DISABLE; vos_dev_ioctl(hSPIm,&spim_iocb); } 4.5 Switching on the LCD Display This is switching on the LCD backlight. void lcd_on(void) { cmd_buffer[0] = CMD_DISP_ON; // Send 'Display On' command write_lcd_cmd(cmd_buffer, 1); } 4.6 Switching off the LCD Display This is switching off the LCD backlight. void lcd_off(void) { cmd_buffer[0] = CMD_DISP_OFF; // Send 'Display Off' command write_lcd_cmd(cmd_buffer, 1); } 4.7 Setting the LCD Contrast This is sending a command to the LCD display to define how bright the image appears. void lcd_set_contrast(unsigned char contrast_value) { cmd_buffer[0] = CMD_DISP_EVOLUME_MODE; // Send 'Set Reference Voltage' command cmd_buffer[1] = contrast_value; write_lcd_cmd(cmd_buffer, 2); } Copyright © 2010 Future Technology Devices International Limited 10 Document Reference No.: FT_000363 AN_161 Vinco Graphics Display Example Version 2.0 ` Clearance No.: FTDI# 190 4.8 Addressing the LCD The LCD is notionally like a large memory where each memory location equals a pixel. You can address this memory (pixel) by pages or by lines and columns.

The IDE generates the .ROM file with a single button click of the “Build” button. Connect the USB port of the VNC2 Debug Module to a PC and load the free FTDI drivers for the FT232R device on the debug module. This will happen automatically via Windows Update if you are connected to their internet. Otherwise refer to the installation guide for your OS: http://www.ftdichip.com/Support/Documents/InstallGuides.htm The IDE should now automatically detect the VNC2 debug module. Connect the other end of the VNC2 Debug Module to the J8 connector of the Vinco. Use the IDE FLASH button to load the .ROM file into the Vinco.
