I am currently working on Heart Beat Monitoring System using finger clip sensor and PIC18F4550 and using USB to connect to PC. My finger clip is using high intensity LED and LDR with LM358. I am trying to write the coding on calculating the heart pulse in PIC using MPLAB C language. I dono how to write the coding or calculate. Can anyone help me on this?
I really am startled. by the above statementin MPLAB..how do I write in C language in PIC? How do i calculate in PIC program?
I really am startled. by the above statement
8-O8-O8-O
Why did you select the PIC18F4550?
Are you going to do the SW development in assembler or in C? Why ?
Do you have a development environment for this PIC?
Give us more detail on the requirements of you project
Why? I am new on using PIC.
I hope you are not new to C?
C is a bit high-level language than assempler. Hence you should have no problem in coding.
Only problem is you have to know the compiler you are using (e.g How it defines different pins/ports)
rest is normal C.
This is why i was surprised why you bother if it is PIC or your PC. If you are using C it is the C language constructs and your logic matters. The intricacies of the underlying architecture is taken care of by your Toolchain.
I guess I have described it properly.
hi this is a simple heart monitor project
you can check it may help you

Thanks ya. Well I am new C language but not C++. I guess they quite alike? Well for the pin assignment..I just need one input for analog input pin in PIC as shown in the figure I attached before. The problem I am facing is like..for instance my friend groups having analog temperature input to same PIC. There is 10 bits for the input. I don't know mine one how many bits..just I dono what form it is. I had tested my sensor output which is about the shape as shown in Calculating the heart rate - data logging experiment results but the peak to peak voltage is 53micro second. Kind of weird..
Thanks for your patient understanding my problem and your help. I deeply appreciate it
For PIC I don't know but there are few. you can consult REC Boomerang too. From the source you can get a feel how difficult it is.
All those are for x86 architecture.
I installed MikroC but I only know how to use it convert C to assembly. Is it possible use MikroC convert assembly to C? How?
