What exactly is IAP (In application Programming)? can anyone, please post a practical example to understand the difference between ISP and IAP.? thankyou
"In System" infers a raw/blank chip from the manufacturer soldered to a board has a mechanism/protocol to allow the device to be programmed easily without some magic interface or programming voltages, ie serial/usb. "In Application" infers the code already loaded (boot loader/app) has it's own mechanism/protocol, usually via more complex and board specific, ie ethernet/wireless, to update itself.
Thank you, Westonsupermare Pier, for giving your valuable time to clear my doubts. it was really heplful... thanks again!!
