I finally managed to build a CMOS to RS232 converter board and cable and now I am testing my roomba 530 with a simple drive application I found on web. The program just moves roomba to 4 main directions.
I want to write my own program too. But before that I have a question that I think only people who have done it before know the answer.
The quesion is, does roomba immideatly sends back some data when its bumpers hit something? What I mean is using that simple driving app, I can drive roomba into something, I would like to know if at the moment that roomba hits something it sends something back to serial port?
I tried with some serial terminal programs but it seems that when I hit something with the roomba, it does not transfers something back to terminal.
If it is not like this, I read in SCI manual that I can send a command to ask for sensor data, but what I need is to immideatly receive something indicating that roomba has hit something.
