How to design software for Digole Smart Display Modules!#1. Introduction of Digole Smart Display Modules (DSDM in following)!

DSDM are special modules which integrated:#A LCD or OLED display.#Display driver with identical API interface.#Boot loader at 57600bps UART, XON flow

control.#PIC18F26K20 or PIC18F46K20 on board.#Other accessory parts to support display.#

Futures:!Available Size: 0.96” to 3.2”.#Display technology: LCD or OLED.#Available color: Monochrome to Full Color.#Available I/O pins: almost all on MCU.#Extended Watchdog Timer (WDT)#4 x 10-bit resolution ADC.#Capture/Compare/PWM (CCP) module#Flash Memory(for user program and data):

48K bytes.#Enhanced CCP (ECCP) module:#- One/Two PWM output (some module

used one to control back light)#

- Selectable polarity#- Programmable dead time#- Auto-Shutdown and Auto-Restart#

Master Synchronous Serial Port (MSSP) module#

- 3-wire SPI (supports all 4 modes)#- I2C™ Master and Slave modes with

address mask#- Enhanced Universal Synchronous

Asynchronous#Receiver Transmitter (EUSART) module:#- Supports RS-485, RS-232 and LIN#- RS-232 operation using internal oscillator#- Auto-Wake-up on Break#- Auto-Baud Detect#

E2PROM(Data only): 1K bytes.#RAM: >=2560 bytes.#MCU frequency: 31KHz to 64MHz, can be

adjusted dynamically on running time.#Program code file format: Intel Hex.#Inventional entering program downloading

mode: double press reset button.#The software can be developed by using: C or assembler program language, such as: XC8, Hi-Tech

C18, CCS, MPASM and more.#All our DSDM embedded the corresponding display driver with identical interface, so, changing the

module on your product is seamless. The embedded driver can do lot of work for you: display characters using U8Glib fonts, draw pixels, lines, circles, rectangles and more, all drawing can be operated with existing contents logically: NOT/OR/AND/XOR, all driver were test completely and tuned carefully.#

By using our DSDM, you can reduce your product developing time significantly, what you need is just focusing on your product’s functions, then call display driver when you need send output to display.

2. Hardware resource map on modules!Legend:#Blue: All function available for user, the module didn’t use it internal#Red: This port/pin was reserved for module, user can’t operate this pin, other wise, the module#Black: Restrict ports/pin, the user can still use the port, but should be deal with it carefully.#

CS: this is the chip selection for display panel, user can use and operation this signal, except want to operate with the panel directly.#

WR:Write signal on display panel;#RD: Read signal on display panel;#D/C: Data/Command signal on display panel;#DATA I/O: Data write to and read from display panel;#SCLK: ST7565 LCD panel’s Clock signal;#SDI: ST7565 LCD panel’s Data in signal;#

3. How to use restrict port/pins (Black letter on above table)!3.1: WR (PA.6), RD (PC.0), D/C (PA.7): These 3 signals are output from MCU to display panel

only, and only activated when CS (PA.4) signal at low, so, user can use it as regular I/O when user’s program didn’t call embedded display function.#

3.2: Back Light (PC.1): if the module used this pin, it will be used to control the backlight on the module, the user can’t use it any more, other wise the backlight will not working properly.#

3.3: Data I/O (PB.0 to PB.7): on most module (except serial display panel), Port B is used as data bus to communicate with display panel, user still can use it as regular I/O port if add a data latch IC (eg. 74HC373) and use another available pin as chip select signal, at this time, WR,RD,D/C can be used combined with port B either.##

4. Design Software for DSDM!Any development tool set will work on our DSDM, such as MPLAB with C/MPASM, CCS, Mikro C and

pure ASM.#The two important things must be pay attention by User’s program:#1) Must be shift from 0H to 4000H, the program memory space from 0H to 3FFFH were occupied by DSDM’s boot loader and display driver.#

2) Don’t use RAM in BANK 14 (RAM address from E00H to EFFH), this BANK RAM used by display driver.#4.1 How to reserve program memory space and RAM on C?!

4.1.1HI-TECH PICC-18:!In the link phase, use the linker directive: -a4000h -L-Psmallconst=f000h!

4.1.2 Microchip C18:!Edit the Linker script 18f452_c.lkr to protect the boot block, and rebuild the C18 startup objects

c018.o and c018i.o. The Linker script 18f4620_c.lkr must be used for models that use a 2048 boot block. Also be certain you have not defined absolute code sections in the source code to start in the boot block. For instance:#

#pragma code InterruptVectorHigh = 0x08#must be changed to!#pragma code InterruptVectorHigh = 0x4008!

4.1.3 CCS:!Add following directives in your .C file#build(reset=0x4000)##build(interrupt=0x4008)##org 0x0000,0x3fff#void bootloader() {##asm# nop##endasm#} // Reserve program space for the bootloader##

4.1.4 PIC Basic Pro:!Had the following line:#DEFINE RESET_ORG 4000h

Digole Digital Solutions

4.2.2.10 Now, the project is set up completely, it’s time to write program now.#We need to create a main .C file in this project: click on the Source Files, then Right

click to pop up the sub menu, select New->C Main File…#

4.2.2.11 type in main file name, here we use the default: new main#

Page � of �13 31

Digole Digital Solutions

4.2.2.12 Input contents like follow, then compile it, the IDE will create a .HEX file, we need to download this .HEX file to DSDM through a USB to UART converter.#

we already write a digole.h file for PICC18 that include all API function and RAM reservation, you can copy it into “include” folder of HI-TECH PICC18, then simply use:#

#include <digole.h>#in your .C file##

Page � of �14 31

Digole Digital Solutions

4.3 Download .HEX file to DSDM!In order to download user program to DSDM, you need an UART port as hardware and

communication software.#To obtain an UART port, we usually use a USB to UART converter (not a USB to RS232

converter, they use same protocol, but with difference logical voltage level, UART use TTL), you can find lot of such adapter from ebay and others.#

Connect DSDM to USB-UART converter:#DSDM # # # USB-UART Converter#GND# # <———># GND#VCC(PWR)# <———># 5V or 3.3V#RX# # <———># TXD#TX# # <———># RXD##

The communication software we recommend is CoolTerm, this software tool work on Windows, MAC OS and Linux, very useful and powerful, here is the download link:#

http://freeware.the-meiers.org#NOTE: We found only CP2102 adapter work at XON correctly, other adapter with which

FT232RL or CH340G will not work at XON, if you use such adapter, you need set 1ms delay after each character send out.

Digole Digital Solutions

After downloading the CoolTerm, we now to demonstrate how to set up the CoolTerm and Download user software to DSDM:#

4.3.1 Run CoolTerm: Double click CoolTerm#

4.3.2 Click: Options icon to set up the communication parameters, then click: OK## a) Select the correct Port## b) Set the Baudrate at : 57600## c) Set the Data Bits as: 8## d) Set the Parity as: none## e) Set the Stop Bits to: 1## f) Set the Flow Control to: XON#

4.3.3 Click: Connect button on tool bar, it will show the port has been connected at the status bar (refer above picture)#

4.3.4 Download .HEX file to DSDM:#

# 4.3.4.1 Select : Connection menu then click Send Textfile, it will open an dialog to let

you browser file.#

4.3.4.2 Select the .HEX file which just created by the software development tool set, on MPLAB with PICC18, it usually under the folder of:#

[Project folder]->dist->default->production folder#4.3.4.3 Double press the RESET button on DSDM quickly, the DSDM will show the 10

seconds countdown screen to wait for the new program(the following pictures are on DSDM160128 Color OLED Module, other modules are similar)#

4.3.4.4 Click the Open button, then the CoolTerm will download the .HEX file to DSDM, there is a downloading progress bar on the DSDM’s screen:#

4.3.4.5 After finishing of user program downloading, the DSDM will start to run user program automatically.##

5. API Documentation!All DSDM embedded bootloader and display API in the MCU program memory space from 0000H to

3FFFH, that’s why the user’s program only can start from 4000H. User’s program can call the embedded API to do lots of things such as display letter, draw line, draw circle, change font and more by:#

1) setting the function you want to call to RAM at 0E00H#2) setting the parameters you want to pass to from 0E01H to 0E3CH#3) making a call to 80H at program memory#We will describe it in more details bellow.#5.1 Memory space map!
