3. Operational Overview

Power-up Sequence:

Upon power up, the controller checks the position of the Mode Select Switch and adjusts the image size

accordingly. The “Switch” position will show the full image while the “Display” position will display only the

middle 52 pixels of the top 36 lines of the image.

OLED Brightness Adjustment Mode:

The controller will then allow the brightness of the two OLED modules to be adjusted. Press the left hand

switch to make both OLED modules dimmer. Press the right hand switch to make both OLED modules brighter.

The brightness can be one of 16 levels between 0 and F where F is the maximum brightness. At the F level the

OLED has a rated life of 15,000 hours. The dimmer the level is set the longer the life of the OLED.

Main Operational Mode:

After a few seconds of user inactivity the controller will move into the main operations mode where the switch

on the left displays the image at the user’s first preset address. The right hand switch will display the image at

the user’s second preset address. The controller will then respond to a switch actuation or a timer expiration as

set by the attributes.

Addresses:

The controller associates one address to the left switch and one address to the right switch. Each switch will

display the image at their associated addresses. The addresses are in hexadecimal. The controller handles the

addresses as a group of addresses with associated images and attributes within user defined loops. Each loop has

a starter address and an ending address. The function of the attributes for each address is to tell the controller

where to point to next either when the switch associated with that particular address is pressed or when a timer

expires. There are three types of attributes:

•Attributes SW1 and SW2 are the Action Addresses. In the starting address the Action Addresses tell the

controller what addresses to point to when the switch associated with that particular address is pressed. In

the ending address the Action Addresses tell the controller what addresses to point to when the loop has

ended.

•The end address, EP1, sets the ending address for the loop.

•T1 and T2 are timers that are multiplied together to set the length of time to stay at one address before

moving to the next address within the loop.

The only addresses that need attributes within the loop are the first and last addresses.

Illustration 1 shows the starting and ending addresses for “Switch A” which is associated with address 0001H.

Switch A could be the left or right switch.

Illustration 2 shows a simple loop where images at addresses 0041H through 0057H are shown in sequence for

two seconds each and will loop continuously until the switch associated with that particular address is pressed

or the loop ends. When that switch is pressed the controller will set the left hand switch to address 0001H and

the right hand switch to address 006AH. If the loop ends before the switch is pressed the left switch will go to

address 0059H and the right switch will go to address 005AH.

Ending Image 0057 0059 005A 0000 00 00

… … … … … … …

If SW1 and/or SW2 for the ending addresses are 0000H the loop will start again. Loops can overlap where, for

instance, the left switch starts at address 0001H and ends at 0005H while the right switch starts at 0002H and

ends at 0006H. The two loops will not interfere with each other.

Timers Operation:

Each switch has an independent timer; timer1 and timer2. Each timer value is the product of the two user

defined variables T1 and T2 of the attributes. The formula for the timer value in millisecond is:

The timer value in ms= (T1)x(T2)

Each of these variables can have a value between 01H to FFH (1 to 255). The timer for a given switch will

be disabled if the T1 value is set to zero. For T2 the zero value is defined as 256. Pressing either switch will

reset the timers for both switches. Holding down either switch will prevent both timers from running. The

4. Operational Details

Power-Up Sequence (Steps 1,2,3)

Upon power-up or reset, controller performs the following steps:

Step 1: Check the status of Mode Select Switch for mode of operation. Initialize according to selected mode.

Step 2: Display dim and bright on the two switches and allow for adjustments of the brightness. There are 16

brightness levels (0 to F). When the internal timer is expired, the controller proceeds to Step 3. Every time a

switch is pressed, the timer gets reset. If a switch is held depressed the timer does not run. Switch activity are

not reported to host.

Step 3: Transmit 11H to host via RS232. Check the microSD for set up value. If set up values are

programmed, get the start address for switch 1, start address for switch 2 and the flag byte. If the set up values

are not programmed use the default values: start address for switch 1 = current address for switch 1 = 0001H,

start address for switch 2 = current address for switch 2 = 0010H and flag byte = 80H.

Step 4:

A. If attributes for start address of switch 1 are programmed, get the attribute for switch 1.

B. If attributes for start address of switch 1 are not programmed, use the default: Switch 1 Action

address for switch 1 = 0000H, switch 1 action address for switch 2 = 0000H, end address for

switch 1 = 0010H Timer2 for switch 1=00H timer1 for switch 1= 0AH.

C. If attributes for start address of switch 2 are programmed, get the attribute for switch 2.

D. If attributes for start address of switch 2 are not programmed, use the default: Switch 2 action

address for switch 1 = 0000H, switch 2 action address for switch 2 = 0000H, end address for

switch 2 = 0020H Timer2 for switch 2=00H timer1 for switch 2= 0DH,

Step 5: Send the pictures from microSD to OLED module according to start addresses.

Main Operational Mode

Step 6:

A. If the switch 1 is pressed, process it. (see details below)

B. If the switch 2 is pressed, process it. (see details below)

C. If the timer for switch 1 is expired, process it. (see details below)

D. If the timer for switch 2 is expired, process it. (see details below)

E. If the switch 1 is released: Transmit B1H to host if flag is enabled.

F. If the switch 2 is released: Transmit B2H to host if flag is enabled.

G. If there is update flag for switch 1 is set, process it.
