Hi all,
Following is a PSoC 5 based load cell measurement system. The project attachment contains Weighing Scale Example and Bridge Sensor Example in the workspace. The Weighing Scale example provides a complete code to measure the weight using a load cell and display the results on an LCD display. The Bridge Sensor example is provided for easily porting the analog front-end example across other sensors. The projects implement Correlated Double Sampling. Moving Average Filter is also implemented to filter the results.

Hi,
Nice Sample!
You may want to change the schematic with the one below, which I took from your project with adding a white rectangle background.

Dear Vasanth,
Would you be so kind to help me to fully understand your design:

Thanks in advance !
