![]() Hooking an oszilloscope to the Tx output of the raspi I don’t see anying coming there, so the minicom remains dead silent. It seems it’s gone nowadays, see /forums/viewtopic.php?f=66&t=123081 But also when I follow the steps in the linked doc to deactivate getty, I don’t get your tutorial to work. On my Raspi3 the /etc/inittab file doesn’t exist. Komunikasi serial arduino dengan vb6 serial#Ive written a Java program to read my Arduinos outputs through Serial port. Funny, I already fail on the very beginning. Komputer mempunyai port-port yang berfungsi sebagai komunikasi dengan. I just found your (super) instructions, and wanted to go through it. ( for both TX-RX and RX-TX connections) – could we put a schottky diode between the “Arduino-RX” to “sensor-TX”, to make sure there can only be a flow from the sensor to the Arduino, and and the diode blocks the other way around ( note: n00b here, so I might be completely misunderstanding it ). Now I’d expect the 3.3V from the sensor TX to Arduino-RX to be “safe”, however you mention in some situations the Arduino-RX can be at 5V, which would then go to the sensor and might break it So question ( assuming not using a level-divider) – why not have 2 voltage dividers? Zapreschennie modi na world of warplanes. I’d like to connect an Arduino Uno to a 3.3v sensor through RX/TX Now I understand Arduino-TX -> sensor-RX needs a voltage divider ( so the 5V of the arduino doesn’t break the sensor).
