+# Bobbycar Controller
+
+## Serial Commands
+
+If Vusb jumper on PCB is soldered, do not connect USB while LiPo is connected!
+
+**echo off**
+Turn off serial command echo.
+Useful for automated transfer.
+
+**echo on**
+Turns on serial command echo.
+Useful for manual command execution.
+
+**test**
+Returns "OK"
+
+**ls**
+List files on SD card in a machine readable way.
+One file per line with full path.
+
+**la -a**
+List files tab formatted. With file sizes.
+
+**cat FILENAME**
+Print out the contents of a specified file.
+If no filename given, the current active logfile is used.
+
+**get FILENAME**
+Sends the contents of a specified file in chunks.
+Waits for the checksum of the send chunks before sending the next chunk.
+Exits with an error message when checksum does not match.
+Used for automated transfer of files.
+
+**sizeof FILENAME**
+Returns the size in bytes of the specified file.
+
+**chunksize SIZE**
+Sets the size of chunks for file transmission. See **get** command.
+Default is 128.
+
+**rm FILENAME**
+Deletes file from sd card.
+
+**log off**
+Turns off logging flag.
+
+**log on**
+Turns on logging flag.
+
+**show stats**
+Prints some current stats values.
+One variable per line.
+Format: parametername<Tab>value
+
+**show sensors**
+Prints some sensor values that are useful in standstill.
+One variable per line.
+Format: parametername<Tab>value
