In the FT_clock application, a swiss-clock graphic with major and minor segments and three clock hands is the desired graphic. Further alternatives for the back-ground for the clock face will be shown (plain gradient face or a face generated from a jpeg image in the case where memory storage is readily available).The clock time can be adjusted by touching the minutes hand and using rotary movements. FT clock is an application that demonstrates the use of FT800 graphical primitives to construct a more complex image. This application utilizes all the features of the FT800 i.e. touch, audio and display. Note that this clock is distinct in nature and not the clock widget that is available in the FT800 widget library. In the FT Clock, three processes, audio playback, image decoding and display list construction are handled. Loading of image and audio, along with the construction of the display list will be as follow: Image uploading : Via the CMD FIFO by Load image command Display list : directly in DL RAM Audio play : via SPI to GRAM 1.1 Overview The document will provide information on the image creation, tagging of audio and touch capabilities, and the structure of displays lists. Further, the application note will outline the general steps of the design flow, including display list creation, and integrating the display list with the system host micro-controller. This document should be read in conjunction with the source code which can be found in section 4 or at: http://www.ftdichip.com/Support/SoftwareExamples/FT800_Projects.htm 1.2 Scope This document can be used as a guide by designers to develop GUI applications by using FT800 with any MCU via SPI or I2C. Note detailed documentation is available on www.ftdichip.com/EVE.htm including: FT800 datasheet Programming Guide covering EVE command language AN_240 FT800 From the Ground Up AN_245 VM800CB_SampleApp_PC_Introduction - covering detailed design flow with a PC and USB to SPI bridge cable AN_246 VM800CB_SampleApp_Arduino_Introduction – covering detailed design flow in an Arduino platform AN_252 FT800 Audio Primer 3 Copyright © 2013 Future Technology Devices International Limited Application Note AN_262 FT_App_FT_Clocks Version 1.1 Document Reference No.: FT_000907 Clearance No.: FTDI# 357 2 Display Requirements This section describes some of the key components of the design. 2.1 Wall Background image In the FT Clock application, the wall background is a JPEG image. There are 10 JPEG images (bgimg0.jpg – bgimg9.jpg) which may be loaded as the application cycles round. The actual clock is overlaid to the coordinates and size matching the clock in the JPEG. To change the background displayed touch the display in the background area. Two bitmap handles are used to assist swapping the images. 2.2 Clock face The clock face (skin) is generated with FT800 primitives such as LINES and FTPOINTS as opposed to the clock widget, allowing for customised hands such as those on a Swiss clock to be generated. The face can be changed by tapping on the clock. This will change the colour of the face background and the hands. 2.3 Date and time Time in the application is initialised to System time from the host controller. The date, month and year can be adjusted by touching the date display. Adjustment in date, month and year can be done only for the first two skins. Time adjustment can be done using the tracker for the hour needle and the minute needle is adjusted accordingly. As the tracker is synced with System time, the second hand movement changes accordingly. 2.4 Audio for changing hour In this application, the time change per hour is indicated by the recorded voice message. When the time changes past the hour, the recorded voice message reports the hour displayed. The audio files are uLAW encoded from a PC application such as aud_cvt from the FTDI utilities web page. There are 12 files (1.ULW – 12.ULW) – one for each hour. 4 Copyright © 2013 Future Technology Devices International Limited Application Note AN_262 FT_App_FT_Clocks Version 1.1 Document Reference No.: FT_000907 Clearance No.: FTDI# 357 2.5 Without SD card If the SD Card is not present, the system can show only two wall backgrounds, and the audio alert is disabled. NOTE: If using an FTDI MPSSE cable then the SD card is not required. 5 Copyright © 2013 Future Technology Devices International Limited Application Note AN_262 FT_App_FT_Clocks Version 1.1 Document Reference No.: FT_000907 Clearance No.: FTDI# 357 3 Design Flow Every EVE design follows the same basic principles as highlighted in Figure 3.1. The active list and the edited list which are continually swapped to update the display.Select and configure your host port for controlling the FT800 then wake the device before configuring the display. The creative part then revolves around the generation of the display list. There will be two lists. The active list and the updated/next list are continually swapped to render the display. Note, header files map the pseudo code of the design file of the display list to the FT800 instruction set, which is sent as the data of the SPI (or I²C) packet (typically <1KB). As a result, with EVE’s object oriented approach, the FT800 is operating as an SPI peripheral while providing full display, audio, and touch capabilities.

The function labelled Ft_BootupConfig in this project is generic to all applications and will start by toggling the FT800 PD# pin to perform a power cycle. /* Do a power cycle for safer side */ Ft_Gpu_Hal_Powercycle(phost,FT_TRUE); Ft_Gpu_Hal_Rd16(phost,RAM_G); /* Set the clk to external clock */ Ft_Gpu_HostCommand(phost,FT_GPU_EXTERNAL_OSC); Ft_Gpu_Hal_Sleep(10); /* Switch PLL output to 48MHz */ Ft_Gpu_HostCommand(phost,FT_GPU_PLL_48M); Ft_Gpu_Hal_Sleep(10); /* Do a core reset for safer side */ Ft_Gpu_HostCommand(phost,FT_GPU_CORE_RESET); /* Access address 0 to wake up the FT800 */ Ft_Gpu_HostCommand(phost,FT_GPU_ACTIVE_M); The internal PLL is then given a prompt by setting the clock register and PLL to 48 MHz. Note 36MHz is possible but will have a knock on effect for the display timing parameters. A software reset of the core is performed followed by a dummy read to address 0 to complete the wake up sequence. The FT800 GPIO lines are also controlled by writing to registers: Ft_Gpu_Hal_Wr8(phost, REG_GPIO_DIR,0x80 | Ft_Gpu_Hal_Rd8(phost,REG_GPIO_DIR)); Ft_Gpu_Hal_Wr8(phost, REG_GPIO,0x080 | Ft_Gpu_Hal_Rd8(phost,REG_GPIO)); And these allow the display to be enabled. To confirm the FT800 is awake and ready to start accepting display list information the identity register is read in a loop until it reports back 0x7C. I will always be 0x7C if everything is awake and functioning correctly. ft_uint8_t chipid; //Read Register ID to check if FT800 is ready. chipid = Ft_Gpu_Hal_Rd8(phost, REG_ID); while(chipid != 0x7C) chipid = Ft_Gpu_Hal_Rd8(phost, REG_ID); Once the FT800 is awake the display may be configured through 13 register writes according to its resolution. Resolution and timing data should be available in the display datasheet. 8 Copyright © 2013 Future Technology Devices International Limited Application Note AN_262 FT_App_FT_Clocks Version 1.1 Document Reference No.: FT_000907 Clearance No.: FTDI# 357 Ft_Gpu_Hal_Wr16(phost, REG_HCYCLE, FT_DispHCycle); Ft_Gpu_Hal_Wr16(phost, REG_HOFFSET, FT_DispHOffset); Ft_Gpu_Hal_Wr16(phost, REG_HSYNC0, FT_DispHSync0); Ft_Gpu_Hal_Wr16(phost, REG_HSYNC1, FT_DispHSync1); Ft_Gpu_Hal_Wr16(phost, REG_VCYCLE, FT_DispVCycle); Ft_Gpu_Hal_Wr16(phost, REG_VOFFSET, FT_DispVOffset); Ft_Gpu_Hal_Wr16(phost, REG_VSYNC0, FT_DispVSync0); Ft_Gpu_Hal_Wr16(phost, REG_VSYNC1, FT_DispVSync1); Ft_Gpu_Hal_Wr8(phost, REG_SWIZZLE, FT_DispSwizzle); Ft_Gpu_Hal_Wr8(phost, REG_PCLK_POL, FT_DispPCLKPol); Ft_Gpu_Hal_Wr8(phost, REG_PCLK,FT_DispPCLK);//after this display is visible on the LCD Ft_Gpu_Hal_Wr16(phost, REG_HSIZE, FT_DispWidth); Ft_Gpu_Hal_Wr16(phost, REG_VSIZE, FT_DispHeight); To complete the configuration the touch controller should also be calibrated /* Touch configuration - configure the resistance value to 1200 - this value is specific to customer requirement and derived by experiment */ Ft_Gpu_Hal_Wr16(phost, REG_TOUCH_RZTHRESH,1200); Ft_Gpu_Hal_Wr8(phost, REG_GPIO_DIR,0xff); Ft_Gpu_Hal_Wr8(phost, REG_GPIO,0x0ff); An optional step is present in this code to clear the screen so that no artefacts from bootup are displayed. /*It is optional to clear the screen here*/ Ft_Gpu_Hal_WrMem(phost, RAM_DL,(ft_uint8_t *)FT_DLCODE_BOOTUP,sizeof(FT_DLCODE_BOOTUP)); Ft_Gpu_Hal_Wr8(phost, REG_DLSWAP,DLSWAP_FRAME); 4.2 Info() This is a largely informational section of code and it starts by synchronising the physical xy coordinates of the displays touch layer with the displays visual layer. A display list is started and cleared: Ft_Gpu_CoCmd_Dlstart(phost); Ft_App_WrCoCmd_Buffer(phost,CLEAR(1,1,1)); Ft_App_WrCoCmd_Buffer(phost,COLOR_RGB(255,255,255)); A text instruction is printed on the display followed by the call to the internal calibrate function: Ft_Gpu_CoCmd_Text(phost,FT_DispWidth/2,FT_DispHeight/2,26,OPT_CENTERX|OPT_CENTERY," Please tap on a dot"); Ft_Gpu_CoCmd_Calibrate(phost,0); The display list is then terminated and swapped to allow the changes to take effect.
