Writes (and reads) a single byte to SPI

Write a HIGH or a LOW value to a digital pin

Prints data to the serial port as human-readable ASCII text followed * by a carriage retrun character '\r' and a newline character '\n' */

use U8X8_PIN_NONE as value for "reset", if there is no reset line */

Description: Setup u8x8 and assign the callback function. The dummy callback "u8x8_dummy_cb" can be used, if no callback is required. Thi

============================================*/ This procedure is called after setting up the display (u8x8 structure). --> This is the central init

Sleep the specified milliseconds

Configures the specified pin to behave either as an input or an output

Prints data to the serial port as human-readable ASCII text.

Reads the value from a specified digital pin, either HIGH or LOW.

Adds a callback to the notification thread.

Converts a 32 bit unsigned number to signed. If the number is negative it indicates an error. On error a pigpio exception will be raised i

Trigger a new relative humidity and temperature reading.

this is a helper function for the U8X8_MSG_DISPLAY_SETUP_MEMORY function. It can be called within the display callback function to carry out the usu

Runs a pigpio socket command. sl:= command socket and lock. cmd:= the command to be executed. p1:= command parameter 1 (if applicable)

this is a helper function for the U8X8_MSG_DISPLAY_INIT function. It can be called within the display callback function to carry out the usual stand

Sets the GPIO level. GPIO:= 0-53. level:= 0, 1. If PWM or servo pulses are active on the GPIO they are switched off.

Stop reading sensor, remove callbacks.

Removes a callback from the notification thread.

Remove any data remaining on the serial buffer

Write a byte. The writing code uses the active drivers to raise the pin high, if you need power after the write (e.g. DS18S20 in parasite power mode)

Runs an extended pigpio socket command. sl:= command socket and lock. cmd:= the command to be executed. p1:= command param

Sets a watchdog timeout for a GPIO. user_gpio:= 0-31. wdog_timeout:= 0-60000. The watchdog is nominally in milliseconds.

Calls a user supplied function (a callback) whenever the specified GPIO edge is detected. user_gpio:= 0-31. edge:= EITH

Perform the onewire reset function. We will wait up to 250uS for the bus to come high, if it doesn't then it is broken or shorted and we return a 0;

Writes binary data to the serial port. This data is sent as a byte * Returns: number of bytes written */

Sets the GPIO mode. gpio:= 0-53. mode:= INPUT, OUTPUT, ALT0, ALT1, ALT2, ALT3, ALT4, ALT5. ... pi.set_mode( 4, pigpio

Get the numberof bytes (characters) available for reading from * the serial port. * Return: number of bytes avalable to read */

Returns True if a new message may be transmitted.

Sets the data rate in bits per second (baud) for serial data transmission
