The USB to Serial/TTL adapter converts data signals from the USB on the computer to serial/TTL for the microcontroller and vice versa. The first approach involves the connection of a USB to serial adapter to the microcontroller. Using a USB to Serial/TTL Adapter USB to Serial/TTL Adapter We will take each of these approaches one after the other and look at the components and setup required to upload code to the microcontroller. This is usually done via two major ways:Įach of these approaches provides the microcontroller with an interface that enables interaction between the computer and the microcontroller.
To program the microcontroller using the Arduino IDE, the microcontroller must be connected via some sort of hardware to the computer. To remove this difficulty, the microcontroller is flashed with the Arduino bootloader, which makes it ready for programming using the simpler and easy to use Arduino IDE. These development platforms, unlike the Arduino IDE usually require high knowledge of C or other programming languages, without the shortcuts and simplified functions which the Arduino provides. They usually require a certain set of tools, including a programmer (hardware), and a development platform (e.g Atmel Studio) for writing code. The Atmega328p microcontroller, like any other microcontroller, can be quite tasking to use for a beginner.
#SPI PROGRAMMER FOR ATMEGA328P HOW TO#
We covered details on preparing the Atmega328p microcontroller for programming by flashing the Arduino bootloader on Atmega328p and today’s tutorial will be a follow up to that tutorial, as we will look at how to program the boot-loaded Atmega328p microcontroller using the Arduino IDE.
