As described earlier that the Arduino MEGA is based on the ATMEGA 2560 the pinout of the ATMEGA 2560 microcontroller chip is shown in the following figure:.

The discussion on the JTAG will be followed in the post later.

One additional feature of the Arduino MEGA is that this board also has the JTAG port.

Out of these 54 digital input / output pins fifteen are PWM (Pulse Width Modulation) enabled pins.

Arduino MEGA has four UARTS for serial communications, one Serial Peripheral Interface computer bus and one I2C (Inter-Integrated Circuit) computer bus.

Note that the Arduino UNO has much lesser Digital Input / Output pins and Analog pins than Arduino MEGA board.

Arduino MEGA has total 54 digital input / output pins and sixteen analog pins.

This microcontroller chip is different from the ATMEGA328P in terms of the digital Input / Output pins, Analog pins and other basic features which will be discussed in detail.

Arduino MEGA is the open-source microcontroller development board based on the ATMEGA 2560 microcontroller IC.

So sit back, keep reading and enjoy learning.

#Arduino mega pinout tx rx drivers#

This implementation is more user friendly on Windows, since no kernel level drivers need to be installed.In this post ( ARDUINO MEGA FOR BEGINNERS)I will discuss the overview of the Arduino MEGA board, pinout of the Arduino MEGA, specifications of the Arduino MEGA, microcontroller IC on which Arduino MEGA is based and finally the comparison of the Arduino UNO board with the Arduino MEGA board. This boot loader is similar to Thomas FischlвЂ™s avrusbboot, except that it is built on top of the HID device class. If the condition is not met, control is passed to the loaded firmware. a jumper), the boot loader waits for data on the USB interface and loads it into the remaining part of the flash memory. If a certain hardware condition is met (this condition can be configured, e.g. The firmware is flashed into the upper 2 kB of the flash memory and takes control immediately after reset. It can be used on all AVRs with at least 2 kB of boot loader section, e.g.

The uploader tool requires no kernel level driver on Windows and can therefore be run without installing any DLLs.Д«ootloadHID is a USB boot loader for AVR microcontrollers.

note USB connection to pins PD2 & PD4 - NOT via RXD on PD0 and TXD on PD1 via a serial to USB converter, as is more usual.Д«ootloadHID is a USB boot loader for AVR microcontrollers.

As can be seen - it uses an ATMega168 and the USB connection is made to two standard digital I/O pins. This is in turn based on the USBaspLoaderДЄ (very) simple 'more or less Arduino compatible' development board which can use this system is Metaboard.

If not, it works in functionally the same manner). (The Trinket is not mentioned here but I'm told that this is what it uses. Here is how the (or a) ADAFRUIT Trinket Bootloader works. The eg ADAFruit Arduino Trinket uses this system.

As TX & RX are also standard digital I/O pins they could be used for this purpose BUT you need dedicated bootloader code to do this and it has inferior performance if a USB to serial converter is available. It IS possible to access USB directly from digital I/O pins. The answer to your question is 'It can be done but it requires a different boot loader, its slower, its technically inferior, it's less standard, it requires a degree of understanding (on someone's part) to get it going, and it can be done The second answer you cite is technically incorrect but 'correct enough' in the context. The first answer that you cite that you say says it is possible is in fact not talking about what you are referring to - it is discussing the use of the RX & TX pins directly when they are not being used for USB connection.
