ASYNCHRONOUS SERIAL
I/O
|
|
|
SERIN |
Serial input with optional qualifiers and variables
for storage of received data. On the BS1-IC, baud rates
of 300, 600, 1200, and 2400 are possible. On the BS2-IC,
any baud rate (up to 50k baud) is possible. Also, the BS2-IC
has a serial input time-out function. |
|
|
SEROUT |
Send data serially. On the BS1-IC, data is sent at 300,
600, 1200, or 2400 baud. On the BS2-IC, data is sent at
any baud rate (up to 50k baud). |
|
|
OWIN |
Input data from a 1-wire device. |
|
|
OWOUT |
Output data from a 1-wire device. |
SYNCHRONOUS SERIAL
I/O
|
|
|
SHIFTIN |
Shift bits in from parallel-to-serial shift register. |
|
|
SHIFTOUT |
Shift bits out to serial-to-parallel shift register. |
|
|
I2CIN |
Input data in from I2C serial device. |
|
|
I2COUT |
Output data out to I2C serial device. |
PARALLEL I/O
|
|
|
LCDCMD |
Writes a command to an LCD. |
|
|
LCDIN |
Reads data from an LCD. |
|
|
LCDOUT |
Writes data to an LCD. |
ANALOGUE I/O
|
|
|
PWM |
Output PWM, then return pin to input. This can be used
to output analogue voltages (0 to 5 V) using a capacitor
and resistor. |
|
|
POT |
Read a 5 to 50K potentiometer and scale result. |
|
|
RCTIME |
Measure an RC charge/discharge time. Can be used to
measure potentiometers (faster than POT on BS1-IC). |
SOUND
|
|
|
SOUND |
Play notes. Note 0 is silence, notes 1 to 127 are ascending
tones, and notes 128 to 255 are white noises. |
|
|
