PSoC 5LP Development Kit Details Communication USB Power Adapter Boost Converter 9-V Battery Input 10-Pin JTAG/SWD/SWO Debug and Prog Header On-board Programming USB 10-Pin MiniTrace Connector 32-kHz Crystal 24-MHz Crystal Port D (CapSense/ Miscellaneous Port) Port E (Analog Port) Reset Button Variable Resistor/ Potentiometer CapSense RS-232 Interface Prototyping Area Character LCD Interface 4.2 Functional Description 4.2.
Hardware The board power domain has five rails: ■ Vin rail: This is where the input of the on-board regulators are connected. This domain is powered through protection diodes. ■ 5-V rail: This is the output of the 5-V regulator U2. The rail is a fixed 5-V output regardless of jumper settings. The voltage in this rail can be less than 5 V only when the board is powered by the USB. This 5-V rail powers the circuits that require fixed 5-V supply. ■ 3.3-V rail: This is the output of the 3.
Hardware Two jumpers govern the power rails on the board. J10 is responsible for the selection of Vddd (digital power) and J11 selects the VADJ of Vdda (analog power). The jumper settings for each power scheme are as follows. Powering Scheme Jumper Settings Vdda = 5 V, Vddd = 5 V J10 in 5 V setting and J11 in 5 V setting. Vdda = 3.3 V, Vddd = 3.3 V J10 in 3.3 V setting and J11 in 3.3 V setting. Vdda = 5 V, Vddd = 3.3 V J10 in 3.3 V setting and J11 in 5 V setting. Vdda = 3.
Hardware The board provides the ability to measure analog and digital power separately. To measure power at a single point, rather than at analog and digital separately, remove the resistor R23 to disconnect the analog regulator from powering the Vdda and short Vdda and Vddd through R30. Now, the net power can be measured at the J10 jumper similar to the digital power measurement. To switch repeatedly between R23 and R30, moving around the zero-ohm resistors can be discomforting.
Hardware Figure 4-4. On-board Programming Interface When the USB programming is plugged into the PC, it enumerates as DVKProg5 and you can use the normal programming interface from PSoC Creator to program this board through the on-board programmer. A zero-ohm resistor R9 is provided on the board to disconnect power to the on-board programmer. 4.2.2.2 JTAG/SWD Programming Apart from the on-board programming interface, the board also provides the option of using the MiniProg3.
Hardware The JTAG/SWD programming using J3 requires the programmer, which can be purchased from http://www.cypress.com/go/CY8CKIT-002. Note While using MiniProg3, only Reset mode is supported with this Kit. 4.2.3 USB Communication The board has a USB communications interface that uses the connector, as shown in Figure 4-6. The USB connector connects to the D+ and D– lines on the PSoC to enable development of USB applications using the board.
Hardware Figure 4-7. Boost Converter 4.2.5 32-kHz and 24-MHz Crystal PSoC 5LP has an on-chip real time clock (RTC), which can function in sleep. This requires an external 32-kHz crystal, which is provided on the board to facilitate RTC-based designs. The PSoC 5LP also has an external MHz crystal option in applications where the IMO tolerance is not satisfactory. In these applications, the board has a 24-MHz crystal to provide an accurate main oscillator. 4.2.
Hardware Figure 4-8. Schematic for Protection Circuit on 5-V Power Line Figure 4-9. Schematic for Protection Circuit on 3.3-V Power Line 4.2.6.1 Functional Description of Circuit The protection circuit will protect from a maximum over-voltage or reverse-voltage of 12 Volts. The cut-off voltage on the 5-V line is 5.7 V and on the 3.3-V line is 3.6 V.
Hardware If you intend to use the regulator power supply from the board to power the external modules, both the P-MOS Q4 and Q5 will always be on, allowing the flow of current with a maximum of 22 mV drop across the circuit when the current consumed by the external module is 150 mA. Note The working of protection circuit on the 3.3-V line and 5-V line is as described above. For the purpose of explanation, the annotation of 3.3-V protection circuitry (Figure 4-9) is used. 4.2.
Hardware Figure 4-10. Port D CY8CKIT-050 PSoC® 5LP Development Kit Guide, Doc. # 001-65816 Rev.
Hardware 4.2.7.2 Port E This is the analog port on this kit and has special layout considerations. It also brings out all analog resources such as dedicated opamps to a single connect. Therefore, this port is ideal for precision analog design development. This port is functionally compatible to port A of the PSoC Development Kit and it is easy to port an application developed on port A. This port has two types of grounds, CGND1 and CGND2.
Hardware 4.2.8 RS-232 Interface The board has an RS-232 transceiver for designs using RS-232 (UART). The RS-232 section power can be disconnected through a single resistor R58. This is useful for low-power designs. Figure 4-12. RS-232 Interface 4.2.9 Prototyping Area The prototyping area on the board has two complete ports of the device for simple custom circuit development. The ports in the area are port 0 and port 3, which bring out the four dedicated opamp pins on the device.
Hardware Figure 4-13. Prototyping Area This area also comprises of a potentiometer to be used for analog system development work. The potentiometer connects from Vdda, which is a noise free supply and is hence capable of being used for low noise analog applications. The potentiometer output is available on P6[5] and VR on header P6 in the prototyping area. 4.2.10 Character LCD The kit has a character LCD module, which goes into the character LCD header, P8. The LCD runs on a 3.
Hardware Figure 4-15. LCD Connected on P8 Connector 4.2.11 CapSense Sensors The board layout considers the special requirements for CapSense. It has two CapSense buttons and a 5-element CapSense slider. The CapSense buttons are connected to pins P5[6] and P5[5]. The slider elements are connected to pins P5[0:4]. The Cmod (modulation capacitor) is connected to pin P6[4] and an optional Rb (bleeder resistor) is available on P15[4]. CY8CKIT-050 PSoC® 5LP Development Kit Guide, Doc. # 001-65816 Rev.

5. Code Examples To access code examples described in this section, open the PSoC Creator Start Page. For additional code examples, visit http://www.cypress.com. Figure 5-1. PSoC Creator Start Page Follow these steps to open and program code examples: 1. Click on a code example from Examples and Kits on the PSoC Creator Start Page. 2. Create a folder in the desired location and click OK. 3. The project opens in PSoC Creator and is saved to that folder. 4. Build the code example to generate the hex file.
Code Examples 5.1 Project: VoltageDisplay_SAR_ADC 5.1.1 Project Description This example code measures an analog voltage controlled by the potentiometer. The code uses the internal SAR ADC configured for a 12-bit operation; the ADC range is 0 to Vdda. The results are displayed on the character LCD. Note The PSoC 5LP Development Kit is factory-programmed with this example. 5.1.2 Hardware Connections The example requires the character LCD on P8.
Code Examples 5.1.4 ■ Range is set to Vssa to Vdda in single-ended mode because the potentiometer output is a single ended signal that can go from 0 to Vdda. Therefore, at 12-bit resolution, the ADC will resolve in steps of Vdda/212. ■ Voltage Reference should be set to Vdda/2 supply voltage when input range is set to ‘Vssa to Vdda’. It is set to 1.65 V here, because by default Vdda jumper setting on the board is set to 3.3 V. If J11 is changed to select 5 V, then this parameter should be changed to 2.
Code Examples 5.2.2 Hardware Connections The example requires the character LCD on P8. Because it uses the potentiometer, the jumper POT_PWR should be in place. This connects the potentiometer to the Vdda. Move jumper J10 and J11 to position 2-3, this will set Vdda to 5 V. 5.2.3 Del-Sig ADC Configuration To view or configure the Delsig ADC component, double-click the component in the TopDesign.cysch file. Figure 5-4.
Code Examples ADC. To set Vdda to 5 V, in the VoltageDisplay_DelSigADC.cydwr window of PSoC Creator, click on the System tab, go to Operating Conditions options. Set Vdda to 5 V. 5.2.4 Verify Output Build and program the code example, and reset the device. The LCD shows the voltage reading corresponding to the voltage on the potentiometer. Figure 5-5 demonstrates the functionality. When you turn the potentiometer, the voltage value changes.
Code Examples 5.3 Project: IntensityLED 5.3.1 Project Description This example code uses a pulse-width modulator (PWM) to illuminate an LED. When the pulse width of the PWM varies, the LED brightness changes. By continuously varying the pulse width of the PWM, the example code makes an LED go from low brightness to a high brightness and back. 5.3.2 Hardware Connections No hardware connections are required for this project, because all the connections are hard-wired to specific pins on the board. 5.3.
Code Examples 5.4.3 Verify Output In normal operation, the project displays the time starting from 00:00:00 when SW2 is pressed. Normal mode is indicated by LED3 in ON state. When you press the SW2 button again, the device is put to sleep. Sleep mode is indicated by LED3 in OFF state. If an ammeter is connected to measure the system current (refer Low-Power Functionality on page 20 for details), a system current of less than 2 µA is displayed.
Code Examples 5.5.2 Hardware Connections This project uses the LCD for display; therefore, ensure that it is plugged into the port. No specific hardware connections are required for this project because all connections are hard-wired on the board. 5.5.3 Verify Output Build and program the code example, and reset the device. The LCD displays the status of the two buttons as On/Off. The LCD also shows the slider touch position as a percentage.
Code Examples Figure 5-10. CapSense Button 5.6 Project: ADC_DAC 5.6.1 Project Description This project demonstrates sine wave generation by using an 8-bit DAC and DMA. The sine wave period is based on the current value of the ADC value of the potentiometer. The firmware reads the voltage output by the board potentiometer and displays the raw counts on the board character LCD display. An 8-bit DAC outputs a table generated sine wave to an LED using DMA at a frequency proportional to the ADC count. 5.6.
