Arduino - PortManipulation

RS-232 signal inverter. Ask Question 0 it shows if the TXD- pin on the Arduino's RS-232 port connector is HIGH when there is no signal, and if that matches the RS-232 port connector on the PC, then those ports are wired the same, and should both work with a cable that

An Arduino power inverter - Hackaday

Direct port access is not for the faint of heart, but it can be much faster for when you are ready to take off some of the Arduino training wheels. Credit to Webbot for showing us the PIN register trick.

Native Assembler Programming on Arduino cYpherpunKat

Port Registers. Port registers allow for lower-level and faster manipulation of the i/o pins of the microcontroller on an Arduino board. The chips used on the Arduino board (the ATmega8 and ATmega168) have three ports: B (digital pin 8 to 13) C (analog input pins) D (digital pins 0 to 7)

Using Analog to Digital Converter ADC in Arduino

To connect these two ports you not only have to invert the signals, but you also have to deal with regulating the potentially harmful RS-232 voltages to something that won't destroy a microcontroller's serial pins. There are a handful of solutions to this problem of voltage converting and inverting. Data is sent from a PC's RS-232 port at
