Page 3: Introduction
Introduction EVBeasyPSoC is a development board designer for the hobbyist and engineers who want to quickly prototype their system based on PSoC microcontrollers from Cypress. Developer has access to all pins of the micro, which are brought to the header (pin connectors) and labeled accordingly. Depending upon the board`s... -

Page 6: Power Supply
Power Supply The board should be supplied from external supply with voltage 7..12V AC, or 9..15V DC, using a standard plug with bolt diameter 2.1mm placed in the supply socket. The board may be supplied form 3.6V accumulator. Shorting Backup jumper enable powering directly from accumulator, shorting VBAT jumper enable powering with Switch Mode Pump Mode. -
Page 7: Peripheral Units
Peripheral Units LED Diodes The board has 8 LED diodes, which make the simplest interface between the system and the user. This is especially useful for the beginners, who want to manipulate or debug their program with different hardware configurations. The diode turns on after grounding of the associated Ldn (n = 0 – 8) pin. -
Page 8: 1-Wire Connector
1-Wire Connector Allows to connect an external devices using an 1-wire interface. Figure 3. 1-Wire Connector I2C Connector Allows to connect an external devices using an 1-wire interface. Extras jumpers placed near connector, allow to connect pull-up resistors. Figure 4. I2C Implementation... -
Page 9: Rs232 Interface
RS232 Interface There is a DB-9 connector on the board, connected with the ST3232 state converter. On the other side of the converter there are pin connectors with converter circuit terminals, allowing to plug in to the processor. Figure 5. RS232 Implementation Switches The board is equipped with 8 micro-switches. -
Page 10: Relay
Relay Access to the relay circuitry consist of the REL pin of the MISC header and pins: NC,NO,COM of the relay header. REL pin is indirectly connected to the base of the transistor. Logic level 0 applied to the REL pin, will activate the relay. External circuits can be controlled via NC, NO, COM I/O pins. Figure 7. -
Page 11: Potentiometers
Potentiometers The board is equipped with two potentiometers, allowing for simulation of the analog circuit outputs. The potentiometer enables the adjustment of voltage in the range 0-VTG. The potentiometers output is accessible on ADJ0 and ADJ1 pin of the MISC connector. Customer can choose a resistance of potentiometer during buying board. -
Page 12: Lm35 Thermometer
LM35 Thermometer Thermometer LM35 allows to measure an environment`s temperature and display it on seven- segment LEDs or on LCD display. Figure 11. LM35 Implementation RTC DS1307 The board has one real time clock with accumulator 3V6 (The board can be also supply form accumulator). -
Page 13: Lcd Display
LCD Display The board has one LCD display interface. The LCD connector has four data lines and two control lines: strobe line E and control line R/S. The display R/W line is connected to ground by jumper; all other lines are available at the pin header. The adjustment of contrast id done by two way: by potentiometer ADJ CONT which output pin ADJC must be then connected with LCD`s pin CONT. -
Page 14: Adjc Potentiometer
ADJC Potentiometer There is a ADJC potentiometer, which allows to control the contrast on LCD. Then output pin ADJC must be connected with LCD`s pin CONT. ADJREF Potentiometer Allow to adjust reference voltage of ADC in range from 0V to VTG. It is connected by jumper AREF to one of microcontroller’s port. -
