I'm new to esp8266 firmware programming. I'm trying to start off by writing simple programs.
I'm using ubuntu linux with the esp-open-sdk. I can compile and flash simple programs (like blink) but I'm really stumped with printing debugging info to the console via the os_printf() function.
I have a simple user_init() function which includes two function calls.
I am expecting to see "hello world" printed on /dev/ttyUSB0 when I use the command "cat /dev/ttyUSB0".
I've already used stty to setup the serial port. I have it setup as such: "stty -F /dev/ttyUSB0 raw" and "stty -F /dev/ttyUSB0 115200".
I have my esp8266 wired properly to a ftdi usb to serial converter. Any ideas on what is going on?
