Microcontrollers are very useful especially when it comes to communicate with other devices, such as sensors, motors, switches, memory and even other microcontroller. As we all know many interface methods have been developed over years to solve complex problem of balancing need of features, cost, size, power consumption, reliability etc.

Interfacing analog sensors using ADC is simple and efficient technique to read data lpcc2148 sensor. The ADC characterized by resolution. The resolution of ADC indicates the number of digital values. This means our digital value or discrete level lies between 0 ppc2148 There is one more term important to understand while dealing with ADC and it is step size.

Step size is the minimum change in input voltage which can be resolved by ADC. The concept of step size is closely associated with the resolution of ADC.

So in ppc2148 case we can measure minimum 2. This is how step size defines an accuracy of ADC circuit. The features are listed as:.

For more details on register description keep datasheet in hand UM, Chapter: The two registers lppc2148 will be concerning about: The circuit connection shown as:. The project is fully tested and functioning. We only have to compile and download.

Once we have done with all settings, just open console. Here is an output from our project:.

We hope this post will help you arc get your ADC up-running. If you have any question then please feel free to drop comment. I am working on it, soon will be posted. I hope you understand that it takes lots of time to document explanation of every line of code.

ADC of ARM7 ( LPC2148 )

Dear sir, Can u pls gelp me with sorting out my difficulty for understanding Initclock ;And inituart ; Functions in this code. And pls help to understand How to claculate clock frequency and the value to load to register for a temperature sensor project.

Your details are much helpful indeed.

We lpc21488 use adc of the 10 bit then which 10 bits can we consider in adc control register What actually it means by 10 bit. Yes, add me to your mailing list. The features are listed as: ADC operating frequency is 4.

Supports power down mode. Burst conversion mode for single or multiple inputs. The circuit connection shown as: Next Introduction of C. Login Username Password Remember Me.
