I want to make the project about Pulse-Oximeter is created source code by keil MDK-ARM and shows result in Labview.
I'm beginning in Micro controller design. Could anyone help or suggest me?
So proceed the same way you would with learning any new skill:
You will need to do plenty of study, and plenty of practice. Nobody else can do this for you. Maybe you'd learn better in a taught class environment?
You will need to start with the basics, and work at it until you reach a level of competence necessary for this task.
You have three topics of study:
1. Microcontrollers (and associated electronics);
2. 'C' programming;
3. Pulse Oximetry.
