Raspberry Pi Usage
The Raspberry Pi has a number of ways it can enter commands and output results. One of the easiest to use is a keyboard, mouse, and the HDMI output; however, if you are working on an embedded project that does not use all these devices, you can also log in on a serial console, as well as view the boot kernel messages.
The serial port settings for the terminal emulator are 115200/8N1, no handshaking.
Configure the Debug Buddy for 3.3V RS232 mode by removing both sets of jumper wires. Then connect the Pi to the Debug Buddy using three wires, as follows:
Connections
| Debug Buddy | Raspberry Pi GPIO Connector |
|---|---|
| TXD J7 pin 1 | RXD pin 10 |
| RXD J7 pin 2 | TXD pin 8 |
| GND (any J2 pin or the black test point loop) |
GND pin 6 |
