 ====== User interface module ======
+(Version 5)
-User interface module is designed for simple tasks and basic process control. Module has three push-buttons and three LEDs, which can be used as digital inputs and outputs of microcontroller. Additionally to simple LEDs the module is equipped with 7-segment indicator, graphical LCD display and alphanumeric LCD outputs. User interface module is handy to use along with other modules enabling to control the output device behavior, like motors and display the sensor readings.

-===== Elektrilised ühendused =====
+===== Electrical connections =====
+User interface module is connected to Controller module to ports PA/PC/PG, which includes the 8-pin ports PA and PC and 6-pin port PG.
-Kasutajaliidese moodul on Kontrollermooduli plaadiga ühendatud porti PA/PC/PG, mis koondab endas 8-viigulisi porte PA ja PC ning 6-viigulist porti PG.
+User interface module is equipped with three buttons S1, S2, S3 which are connected to ports PC0, PC1, PC2 accordingly. The other end of buttons are connected through the resistors to ground (logical 0). The module board has places for the capacitors to build up the RC filter for buttons, but not included on the standard set. LED1, LED2 and LED3 on the module are connected to the ports PC3, PC4, PC5 accordingly. The anodes of LEDs are connected to the supply (logical 1).
-Moodul on varustatud kolme nupuga: S1, S2 ja S3, mis on ühendatud vastavalt PC0, PC1, PC2 viikudega. Nuppude teine ots on läbi kaitsetakistite ühendatud maaga (loogiline 0). Moodulil olevad 5 mm LED-id: LED1, LED2 ja LED3 on ühendatud vastavalt PC3, PC4 ja PC5 viikudega. LED-ide teine ots (anood) on ühendatud toitega (loogiline 1).

-Kasutajaliidese moodul on varustatud ühe 7-segmendilise numberindikaatoriga, mis on ühendatud kolme mikrokontrolleri väljundviiguga läbi ajuri A6275. Ajuri andmesignaal (S-IN) on ühendatud viiguga PC6, taktisignaal (CLK) viiguga PC7 ja lukustussignaal (LATCH) viiguga PG2.
+User interface module is equipped with 7-segment indicator, which is connected with microcontroller ports through the driver A6275. Driver data bus (S-IN) is connected to pin PC6, clock signal (CLK) to the pin PC7 and latch signal (LATCH) to pin PG2.

+The graphical LCD display on module is connected to port PA. In parallel the same port has external connector where all pins are aligned according to the standard 2 x 16 alphanumeric LCD 4 bit control. It is user choice, whether to use the graphical or alphanumeric LCD. It is not possible to use both on the same time. Graphical LCD has the background light which can be logically controlled by the software. The back-light intensity of alphanumeric LCD is regulated with on-board resistor and graphical LCD back-light can be controlled by the software. Both LCD displays are connected to the port PA but only one at a time can be used. When selecting the alphanumeric LCD the jumper should be removed to avoid the random control of graphical LCD background light.
-Kasutajaliidese moodulil paikneb graafiline LCD, mis on ühendatud porti PA. Samasse porti on paralleelselt ühendatud ka ribapesa, mille viigud on joondatud vastavalt standardse alfabeetilise LCD viikude järgi. Kasutaja saab ise valida, kas kasutab plaadil paiknevat graafilist LCD-d või ühendab eraldiseisa alfabeetilise LCD. Samaaegselt mõlemat kasutada ei saa.

-===== Mooduli ühendamine =====
+===== Connecting module =====
-Mooduli ühendamine on soovitatav teostada alltoodud järjekorras. Enne ühendamist veenduda, et Kontrollermooduli toide oleks lahti ühendatud.
+While connecting the module it is suggested to follow the order as described below. Before connecting any cable make sure that the power is removed from Controller board.
-  - Ühendada ettevaatlikult Kasutajaliidese moodul Kontrollermooduliga.
+  - Connect gently the User interface module with Controller module.
-  - Ühendada vajadusel programmaator Kontrollermooduliga.
+  - If needed connect the JTAG programmer with Controller module.
-  - Ühendada Kontrollermooduli toide.
+  - Connect the power supply with Controller module.
