In practice a 16 bit counter plus pre/post scalers is more than sufficient to get "close enough" to arbitrary baud rates. UART serial can tolerate slight baud rate mismatches.

I have a microcontroller (PICAXE 20X2) and a pot meter. I programmed the micro so that it sends any change of pot meter to serial port of PC. Obviously it is a 8bit ADC. Now the interesting thing f...

RS232 has a wide range of operation, anything from 3 to 15V should work, although running at a lower voltage is risky and some poorly made receivers may prefer some voltages over others. The different …

Dec 11, 2016 · Most of the time RS-232 and UART come together in serial communication theories. Are they both the same? From my readings I concluded UART is a hardware form of the RS-232 …

I think the minimum for simplex communication are TX so we can transmit and the power supply pins +Vcc and GND. That is all we need. When do we need to use all 9 pins of RS-232? I think that the re...

Aug 14, 2012 · What is the difference between RS232 and Serial? What are the core differences between all of these communication methods: reliability, cost, application, speed, hardware …

I'm looking to splice wires from a DB-sub (9 pin) connector out to a breadboard but I'm getting different pictures for color-coding which makes me confused. What's more confusing is the connect I h...

Aug 27, 2015 · What is the maximum length of serial cable I can use, to connection work properly? Is length of serial cable in connection with baud rate? I am using about 5 meter cable at speed 38400 …

May 15, 2012 · Real RS232 has a voltage swing of more than 10 Volt between mark and space state. And the 147 feet is for 19200 baud only. OP is talking about 3V3 UART and 115200 to 921600 baud: …

Sep 17, 2018 · I am reverse engineering an RS-232 to RS-485 converter to understand how it works. I have attached the schematic that I reverse-engineered from the PCB (apologies for the hand-drawn …
