The timer counts seconds and starts devices at a specified time. It is equipped with graphical (64x128) display with a resistive touch panel on it. The main chip is from the family of MSP430 (MSP430F2252) which in comparison to Atmega has very low power consumption.
The LCD display is supported by SPI.
The program is written in C (with self made fonts and icons).
Many soldered elements are SMD type.
At normal work, the circuit takes about 280 microamperes, but after shutting down the display (an option in the menu) the consumption drops to 2 microamperes.
Some of mounted elements:
MSP430F2252 – main chip
EA DOGL128W-6 – LCD screen
EA TOUCH128-2 – touch panel
EA WF100-04S – touch panel connector
EA LED68X51-A – LCD backlight
