Use the ESP8266 for serial TTL comm
Posted: Mon Dec 15, 2014 12:32 pmHi all, i hear something about this toy around there... I'm looking for a cheap way to connect wirelssy the nodes of my DIY home automation system based on PPTEA (Made in Italy PIC18F2550 BASIC-like IDE by www.energialternativa.org).
System nodes have a TTL serial port with no hardware control lines (just TXDATA and RXDATA), and at the moment they are connected over a 2wire bus using MCP2551 transceivers, so the communication is a point-multipoint serial over a CAN hardware bus.
Can i connect and use the ESP8266 via TTL UART (with 5V to 3.3V level adjust) without have to use I2C and so on?
Thank you all.
