There is also 20 holes (J5) at the bottom of board for user to solder the 90 degrees 20 pins header connects with the bridging cable to any of your product or development kit working with this EXT2 board. For further request to extend the applications, this EXT2 board has built in touch panel connector (J13) is able to control by MCU via the I2C interface. We also provide the front light guide connector (J10) to supply power if you have EPD that integrates with such function. EPD Extension Kit Gen2 (EXT2) 30 [User’s Guide] Rev.05 3.1.1 Headers and Connectors  eTC EPD connector (J1) This is a 40-pins 0.5mm pitch of ZIF type FPC connector to connect with PDi’s EPD that is embedded G2 COG. For more details of the 40 pin assignment, please refer to the product specification of each size of EPD can be downloaded from PDi website.  iTC EPD connector (J2, J3) This is a J2 26-pins 0.5mm pitch of ZIF type FPC connector to connect with PDi’s EPD that is embedded iTC driver. The connector supports dual contact. The width of the FPC is 34-pins with 8 dummy pins. The J3 is a 24-pins FPC connector which is removed the pin#1 and pin#26 of J2 connector. It’s pin-to-pin (from #1 to #24) to the #2 to #25 of 26-pins connector. For more details of the 26 pin assignment, please refer to the EPD product specification on PDi website.  LaunchPad stacking connector (J4 & J6) There are two 20-pins connectors at the backside of EXT2 board to stack on TI LaunchPad directly. We use the outer side pins only. The pin assignment is listed on the rear side of PCB.  8 position DIP switch (J7) This DIP switch is used for differentiating driver type (iTC, eTC) and different components. If you didn’t configure this switch correctly before updating the EPD, the image shows on EPD may has abnormal phenomenon like broken image, different color, wrong pixel data or ghosting. For more details of the configuration, please refer to Table 2-1 Configuration of the DIP switch. EPD Extension Kit Gen2 (EXT2) 31 [User’s Guide] Rev.05 3.2 How to bridge EXT2 with other development kit If you will use our EXT2 board to bridge with your product or other development kit, there is Bridging header (J5) which is pin-to-pin to J4 and J6. The pin assignment is listed on the front side of PCB. Please use the 90 degree 20-pins header to solder on the backside of PCB like the picture below. We highly recommend cutting the protruding portion of the pin header in order to avoid breaking the EPD. After soldering the header on the EXT2 board, you are able to connect the bridging cable with the pin headers of other development kit or your product. Please note there is a white dot on the connector of bridging cable indicates the pin 1. EPD Extension Kit Gen2 (EXT2) 32 [User’s Guide] Rev.05 The pin assignment is listed below.

Working with TI CCS Project Code As you can find there are many configurations in the projects which are PDi Apps and some Single drivers. The Single driver means it’s not working with PDi Apps and will toggle between two images right away after debugging the project. It helps you to simply test the basic global update function with your connected EPD. It’s also the driving waveform that you will migrate to your product using the chosen EPD. The descriptions in this section will focus on the single driver. The project model in the CCS project consists of the main project “EPD_drivers” and some supported LaunchPad_name projects. 4.1 EPD_drivers Project All of the driving waveform source code of supported EPDs with different FPL and driver are placed in this project including the API (application interface).  FPL_drivers folder: You can find all the driving code under this folder for your chosen EPD. If you cannot find the model in this folder, please contact us to request the driving source code. The more advanced version of the project, the more driving code of EPDs will be supported under this folder. You will find the file format is like the configuration that we describe before: DriverType_(DriverID if eTC)_Size_FPL The captured picture below is for example. Your project code may be listed less or more than the example. EPD Extension Kit Gen2 (EXT2) 36 [User’s Guide] Rev.05  - EPD_drivers.h: This file defines the main structures of EPD and COG type, the enumerations and the constants. - DriverType_Size_FPL.*: The most of driving source code for each supported EPD including the power on, initialization, update and power off stages. This is the waveform code you will migrate into your project for driving your chosen EPD. Please note the LUT for iTC EPDs are compiled in the library (.lib file) with each Launchpad. The code in the iTC_*.c file is for sending update command by OTP. - iTC_Engine.*: This file is used for iTC EPDs. In each of iTC_Size_FPL.c file, the code will always call functions from this iTC_Engine.c to extract the arrays (LUT) to get the corresponding data and set to each of predefined constant for later use. COG_Drivers_List.h file: This file defines the driver list and functions that will be supported in each of LaunchPad project.  EPD_interface.* file: The main function interfaces for each project to call with.  Extern_Board_HW_Driver.h file: If you want to compile the “EPD_drivers” project as library, you need this file to compile with together. EPD Extension Kit Gen2 (EXT2) 37 [User’s Guide] Rev.05 4.2 LaunchPad Name Project In MSP-Exp430F5529LP project, we have copied the driver files in [driverlib] folder. If there is new update from F5529 LaunchPad, you can copy the driver files into this folder. In MSP-Exp432P401R and EK-TM4C123GXL projects, we have linked the drivers with your local installed MSPWare and TivaWare folder. (Refer to section 2.2.4) The folder structure in [src] folder of each LaunchPad project is same. The included or excluded files depends on which configuration you’ve set.  HW_drivers folder: Under this folder, you will find the most important driver files to work with the LaunchPad. If you will bridge the EXT2 to other development kit or your product, these files are the keys to modify with. - Board_HW_Driver: defining and configuring all the GPIO pins including SPI and timer. - EPD_Temperature_IIC: set and get the temperature from the onboard S5851AAA sensor via I2C interface. - Flash_Mem_Map: get the block and address from the onboard serial Flash memory EPD Extension Kit Gen2 (EXT2) 38 [User’s Guide] Rev.05 MX25V8005.  - Mem_Flash: access with the onboard serial Flash memory MX25V8005. - Ringbuf: set the ring buffer (FIFO) for transmission and reception. - UART_Driver: configure and control with the UART interface. PDI_apps_drivers folder: The functions and modules to work with the PDi Apps utility. To understand the functionalities, you have to get the source project code of PDi Apps and understand the operating commands and data flow between PDi Apps and these files under this folder. The source codes are linked from the physical project folder under root/PDI_apps_drivers.  PDI_displays_drivers folder: The files under this folder are linked from EPD_drivers project to get synchronization for the EPD driving.  Conf_EPD.h file: This file is used for single driver mode only (it doesn’t work with PDi Apps mode). - Once you set the Active configuration from project in CCS to “eTC_G2_*” like the capture below, you will need to configure this file when in single driver mode. - You can skip the definition if you set the other “iTC_*” configuration in single driver mode. - Check the EPD size of your connected eTC display, find the non-gray area and the “#define USE_EPD_SIZE s_EPD_200” line, change the s_EPD_200 to size you are connected. Options are sEPD_144 for 1.44”, sEPD_190 for 1.9”, sEPD_200 for 2.0”, sEPD_260 for 2.6” and sEPD_271 for 2.71” (2.7”).  Main_single_driver.c file: The main file for selecting single driver mode.  Main_PDI_APPs.c file: The main file for selecting PDi Apps mode.
