DemoKit-LG2 User’s Manual 3.7 SB1, SB3, SB4, SB5 and SB6 Soldering Bridges The SB1, SB3, SB4, SB5 and SB6 soldering bridges allow the board to be configured in a variety of ways, as described in Table 2. Figure 5. Soldering Bridges SB1 3 2 1 SB3 SB4 3 2 1 1 2 3 SB5 SB6 1 2 3 Table 2.
DemoKit-LG2 User’s Manual 3.8 CN7 USB Interface Connector The CN7 connector provides a means to connect the board to FPL3 flash programming software to program application software into the MCU’s internal flash memory. Additionally, the on-board debugging function uses connector CN7 for communication with the host computer. CN7 also provides the board’s 5-volt power supply.
DemoKit-LG2 User’s Manual 3.9 CN2 Flash Programmer Connector The CN2 connector (not assembled) allows connection of the PG-FP4 flash programmer (available separately) to DemoKit-LG2 to program application software into the MCU’s internal flash memory.
DemoKit-LG2 User’s Manual 3.10 OCD connector CN8 Connector CN8 (not assembled) allows connection of the QB-78K0MINI on-chip debugging emulator (available separately) to the DemoKit-LG2 to use the MCU’s on-chip debugging function. Table 4.
DemoKit-LG2 User’s Manual is equal to 32 Hz (maximum 100 Hz) within the complete temperature range. The LCD pin assignments, connections and segment definition is shown in Table 6: Table 6.
DemoKit-LG2 User’s Manual 3.12 Temperature Sensor For temperature measurement and primarily as an application example, a silicon temperature sensor KTY13-5 is connected to the input port of the 16-bit timer/event counter 00, equal to port P00 of the MCU. The temperature sensor has a resistor range of R25 min = 1950 Ω and R25 max = 1990 Ω at 25° centigrade, with IOP = 1 mA. The distribution of the temperature factor kT is shown in Table 7: Table 7. Distribution of Temperature Factor kT 1.
DemoKit-LG2 User’s Manual Figure 8. Typical Dependence of Sensor Resistance The following equation, which approximates the characteristic curve, calculates temperature at the sensor according to the change in the sensor’s resistance: T = 25 + with: α² - 4 x β + 4 x β x kT 2xβ -3 α = 7,88 x 10 x K -5 °C -1 β = 1,937 x 10 x K kT = - α -2 RT R25 The temperature is measured using the dual-slope method in which a resistor value can be converted into a digital countervalue.
DemoKit-LG2 User’s Manual internal interrupt is generated. The capture value is read using this interrupt. In the next step, the C18 capacity will be discharged again. The same procedure starts once more with port P03. This time the capacitor is charged via the unknown resistor RVAR of the temperature sensor and after the threshold is reached again the second timer value is read out.
DemoKit-LG2 User’s Manual VDD 1- e 1- e e tREF RREF x C tREF RREF x C tREF RREF x C = VDD 1- e - = 1- e - tVAR RVAR x C tVAR RVAR x C tVAR RVAR x C = e tREF RREF x C = tVAR RVAR x C tREF RREF = tVAR RVAR RVAR = RREF x tVAR tREF The C18 capacitor and VDD supply voltage do not influence the accuracy of the measurement. Only the absolute value of the RREF reference resistor has an influence, because these parameters will not change during one measurement.
DemoKit-LG2 User’s Manual Figure 9 shows a diagram of the dual-slope circuit: Figure 9.
DemoKit-LG2 User’s Manual Example: VDD = 5 V; Vthreshold = VC = (0,4 … 0,7) VDD Typical: Vthreshold = 0,6 × VDD RREF = 10 kΩ; C = C18 = 220 nF t = - RREF x C x ln 1- t = - 10 kΩ x 220 nF x ln VC VDD 1- 0 t = 2,0158 ms 3.13 Q1 Phototransistor For light incidence measurement and primarily as an application example, a PT15-21C phototransistor is connected to the ANI0 analog input, which is equal to port P20 of the MCU. 3.
DemoKit-LG2 User’s Manual 3.16 CN3, CN4 and CN5 External Connectors CN3, CN4 and CN5 are connectors for external user hardware. The MCU signals are connected to CN3, CN4 and CN5. The DemoKit-LG2 board also provides a wire-wrap field area—connector CN3—for the integration of additional application hardware. Figure 10.
DemoKit-LG2 User’s Manual 3.17 Microcontroller Memory Map The MCU’s memory layout is shown in Figure 11. Figure 11. Microcontroller Memory Map The DemoKit-LG2 does not reserve any resources of the MCU; consequently all available MCU memory is free for application software.
DemoKit-LG2 User’s Manual 4. On-Chip Debugging The DemoKit-LG2 board offers two possibilities for on-chip debugging (OCD). The on-board debugging function allows on-chip debugging without a need for external debugging hardware. In this mode, the default USB / UART connection to the host computer serves as the debugging interface.
