What is the use of the MOSI and MISO pins?(a) To download code from the microcontroller to the computer(b) To verify the program that the computer uploads to the microcontroller(c) To erase the SRAM of the microcontroller(d) To dump or transfer programs from the computer to the microcontrollerThe question was asked in my homework.This interesting question is from Uploading in section Arduino Programming of Arduino
Answer» The correct option is (d) To dump or TRANSFER programs from the computer to the microcontroller The explanation: The MOSI and MISO pins are a PART of the SPI (Serial Peripheral Interface) for transferring data over short distances. It is a FORM of Synchronous Serial Communication. These pins COMMIT hex data from the computer to the EEPROM and flash memory of the microcontroller.
