#BO2 GSC STUDIO IMPOSSIBLE TO CONNECT DRIVER#

This interface is asynchronous which means that the timing is more critical. PC (better RS232) has +/- 3-12V, the negative levels are usually the bigger problem than the voltage but you should never connect TTL UART devices directly to RS232, that’s correct. I2C has the additional advantage that by design you’re able to connect devices with different voltage levels (5V and 3V3) to the same bus without destroying them because the lines are pulled up by resistors and not actively by the master or slave devices.ĬOM port style TX/RX line pins that run at 5V while PC com port runs at 12V. The address can be found out with a utility code.Ĭan be found is correct, but usually you look that up in the datasheet. There are TX0/RX0, TX1/RX1, TX2/RX2 pins on mega boards that allow connecting to other microcontrollers. #BO2 GSC STUDIO IMPOSSIBLE TO CONNECT PC#Įxamples of I2C modules that I have are:ġ602, 16x2, 20x4, etc LCD controller module/breakout boardĬOM port style TX/RX line pins that run at 5V while PC com port runs at 12V. The address can be found out with a utility code. I2C requires assigning addresses in a sketch/code of the device to communicate. #BO2 GSC STUDIO IMPOSSIBLE TO CONNECT PC#.
