I am afraid if you post on this part of the forum you need to post in English. There is a Portuguese section or you could use Google Translate.
Could someone please help me !!
I have a Mega Arduino and need to send and receive TIC (Turbo Instrument Controller) commands and information, but I can not.
I have the tic serial communication manual, with the list of commands, but I can not send them through Arduino or receive the answers ..
I wanted to know if it is possible to do the Arduino serial communication with TIC!?
I looked at the manual you sent a link to. I could not find 'USB' in it, but it does mention RS232 and RS485. The Arduino has a serial link but it is not at RS232 voltage levels. Connecting RS232 directly to the Arduino will damage it. You need to use an RS232 or RS485 shield.
