Fixing the DTR pin. However, there it has code to fire the DTR pin briefly before sending the data. This pin typically connects to a capacitor which connects to the reset pin on your arduino. Bouncing the pin would usually reboot the arduino, but it also announces to the optiboot system to use the D0 and D1 pins as serial RX/TX briefly to

Serial HOWTO: Pinout and Signals - tldporg

Data Terminal Ready (DTR) is a control signal in RS-232 serial communications, transmitted from data terminal equipment (DTE), such as a computer, to data communications equipment (DCE), for example a modem, to indicate that the terminal is ready for communications and the modem may initiate a communications channel.

How do I program this Arduino Pro Mini with this CH340G

RS232 Shield is a standard communication port for industry equipment. This module is base on MAX232,which is a dual driver/receiver that includes a capacitive voltage generator to supply TIA/EIA-232-F voltage levels from a single 5-V supply.

RS232 to TTL - Аппаратная платформа Arduino

Arduino sends low to DTR, which translates to -6V (-5. 6V to be more precise) for 22ms sent by the PC to the RS232 DTR pin. -5. 6V during 22ms is the AutoReset signal. At the reset pin, I measure the same 22ms signal, but it swings from +5V to zero and bounces to +10V.

Arduino Uno as an FTDI RS232 to Serial Adapter - codeseekah

/14/2010The DTR pin is the one in the corner marked BLK. The reset capacitor is above the pin marked RAW. Unless they are reversed and the hole that is actually closer to the tiny capacitor is the DTR. Sometimes these Arduino clones have the header pattern of holes reversed, sometimes the silkscreen is reversed, and sometimes they're all correct.

Arduino Playground - DisablingAutoResetOnSerialConnection

The Arduino Pro Mini is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, an on-board resonator, a reset button, and holes for mounting pin headers.

Arduino Uno - Farnell element14

The DTR pin allows an Arduino target to auto-reset when a new Sketch is downloaded. This is a really nice feature to have and allows a sketch to be downloaded without having to hit the reset button. This board will auto reset any Arduino board that has the reset pin brought out to a 6-pin connector.
