System features (touch board connected)
Connect the STEVAL-CBP007V1 board to STEVAL-ILL029V2 with connectors J1 (5-pin)
and J2 (4-pin) on the touch board, mating with the female connectors J6 (5-pin) and J7 (4-
pin), on the host board. It is important that the touch board is mounted with proper
orientation before the system is powered on.
On powering on the system, a rotating text message “STLED325-STMPE24M31” is
displayed on the 7-segment display. After this, channel-brightness information is displayed
followed by blinking, one time, of all LEDs present on the touch board. After this sequence is
over, the system is ready for operation. There are a total of 7 LEDs at the bottom of the
individual keys: BRIGHT+, BRIGHT-, CH+, CH-, OK, DEMO, and MENU. Touch of any of
these keys is indicated by blinking of the corresponding LED as well as a buzzer sound.
Channel number - brightness level display mode
In this mode the system displays the channel number (on the leftmost two 7-segment
display modules) and brightness level (on the rightmost two displays). Channel number and
brightness can be increased/decreased using the touchkeys provided on the board (CH+,
CH-, BRIGHT+, and BRIGHT-).
A similar operation can be performed using the remote control keys explained in
Section
Maximum and minimum limits for the channel number are 99 and 00 while the maximum
and minimum values for brightness level are 16 and 1 (16/16, 1/16).
Brightness level is also shown by the number of discrete LEDs glowing. (1 LED each for 2
levels). Brightness level can also be increased/decreased using the 8-channel touch status
type rotator present on the board. The brightness increases on clockwise rotation and
decreases for anticlockwise rotation.
In one complete rotation, the brightness changes by 16 levels.
RTC operation
STLED325 also features an inbuilt RTC. A MENU key on the touch board is provided to
select RTC set/view options. Various touchkeys can be used to operate the real time clock.
Use the MENU touchkey to enter into menu options and navigate through them. Touch the
MENU once - “rtc' is displayed. Now touch OK to enter into RTC options. By using the
MENU key the user can navigate through:
“TIME” (view time), “DATE” (view date), “SETT”(set time), “SETD”(set date), “SETA”(set
alarm).
Display time
Choose MENU to go to “rtc” and then OK. “tIME” is displayed. Now choose OK again to go
to view time. “HH.MM” is displayed for a second to signify time display in Hours-Minutes
format, followed by current RTC time display with hours and minutes separated by a “.”.
Choose OK again to exit to the channel-brightness display.
