Abstract
ARM7 LPC2148 Tyro Board
The ARM7 LPC2148 Tyro board is specifically designed to help students to master the required skills in the area of embedded systems. The kit is designed in such way that all the possible features of the microcontroller will be easily used by the students. The kit supports in system programming (ISP) which is done through serial port.
NXP’s ARM7 (LPC2148), ARM Tyro Kit is proposed to smooth the progress of developing and debugging of various designs encompassing of High speed 32-bit Microcontrollers.
Temperature Sensor
The LM35 series are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. The output of sensor converted to digital that easy connecting with microcontroller.
Interfacing LM35
As you can see the third pin is connected to GND, the first pin is connected to VCC & the second pin is connected to the Microcontroller input. Just use single PIN female to female wire to connect with the leads of LM35 temperature sensor. So when the temperature is sensing, it give the sensor reading to controller.
Interfacing LM35 with LPC2148
Read the temperature in LPC2148 Tyro Board from temperature sensor LM35. The ARM7 LPC2148 Tyro board uses the ADC pin for reading temperature from temperature sensor LM35. The reading output is displayed into PC through UART1.
The 10 bit ADC used for reading the temperature from LM35. Basic clocking for the A/D converters is provided by the VPB clock. A programmable divider is included in each converter, to scale this clock to the 4.5 MHz (max) clock needed by the successive approximation process. A fully accurate conversion requires 11 of these clocks.
