WiringPiMBS.delay(HowLong as UInt32)

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
method	WiringPi	MBS Linux Plugin	15.3	❌ No	❌ No	✅ Yes	❌ No	Desktop, Console & Web

This causes program execution to pause for at least howLong milliseconds.

Due to the multi-tasking nature of Linux it could be longer. Note that the maximum delay is an unsigned 32-bit integer or approximately 49 days.

WiringPiMBS.delayMicroseconds(HowLong as UInt32)

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
method	WiringPi	MBS Linux Plugin	15.3	❌ No	❌ No	✅ Yes	❌ No	Desktop, Console & Web

This causes program execution to pause for at least howLong microseconds.

Due to the multi-tasking nature of Linux it could be longer. Note that the maximum delay is an unsigned 32-bit integer microseconds or approximately 71 minutes.

Delays under 100 microseconds are timed using a hard-coded loop continually polling the system time, Delays over 100 microseconds are done using the system nanosleep() function – You may need to consider the implications of very short delays on the overall performance of the system, especially if using threads.

WiringPiMBS.digitalRead(pin as Integer) as Integer

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
method	WiringPi	MBS Linux Plugin	15.3	❌ No	❌ No	✅ Yes	❌ No	Desktop, Console & Web

WiringPiMBS.I2CSetup(devId as Integer) as Integer

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
method	WiringPi	MBS Linux Plugin	15.3	❌ No	❌ No	✅ Yes	❌ No	Desktop, Console & Web

This initialises the I2C system with your given device identifier.

The ID is the I2C number of the device and you can use the i2cdetect program to find this out. I2CSetup() will work out which revision Raspberry Pi you have and open the appropriate device in /dev.

The return value is the standard Linux filehandle, or -1 if any error – in which case, you can consult errno as usual.

E.g. the popular MCP23017 GPIO expander is usually device Id 0x20, so this is the number you would pass into wiringPiI2CSetup().

WiringPiMBS.piBoardRev as Integer

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
method	WiringPi	MBS Linux Plugin	15.3	❌ No	❌ No	✅ Yes	❌ No	Desktop, Console & Web

This returns the board revision of the Raspberry Pi.

It will be either 1 or 2. Some of the BCM_GPIO pins changed number and function when moving from board revision 1 to 2, so if you are using BCM_GPIO pin numbers, then you need to be aware of the differences.

Some examples using this method:

• /Linux/Temperature Sensor
• /Linux/wiringPi/WiringPi

WiringPiMBS.piHiPri(pri as Integer) as Integer

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
method	WiringPi	MBS Linux Plugin	15.3	❌ No	❌ No	✅ Yes	❌ No	Desktop, Console & Web

This attempts to shift your program (or thread in a multi-threaded program) to a higher priority and enables a real-time scheduling.

The priority parameter should be from 0 (the default) to 99 (the maximum). This won’t make your program go any faster, but it will give it a bigger slice of time when other programs are running. The priority parameter works relative to others – so you can make one program priority 1 and another priority 2 and it will have the same effect as setting one to 10 and the other to 90 (as long as no other programs are running with elevated priorities)

The return value is 0 for success and -1 for error. If an error is returned, the program should then consult the errno global variable, as per the usual conventions.

Note: Only programs running as root can change their priority. If called from a non-root program then nothing happens.

WiringPiMBS.piLock(Key as Integer)

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
method	WiringPi	MBS Linux Plugin	15.3	❌ No	❌ No	✅ Yes	❌ No	Desktop, Console & Web

Locks a synchronization lock.

These allow you to synchronise variable updates from your main program to any threads running in your program. keyNum is a number from 0 to 3 and represents a “key”. When another process tries to lock the same key, it will be stalled until the first process has unlocked the same key.

You may need to use these functions to ensure that you get valid data when exchanging data between your main program and a thread – otherwise it’s possible that the thread could wake-up halfway during your data copy and change the data – so the data you end up copying is incomplete, or invalid.

WiringPiMBS.piMakerNames(index as Integer) as string

Unlocks a synchronization lock.

These allow you to synchronise variable updates from your main program to any threads running in your program. keyNum is a number from 0 to 3 and represents a “key”. When another process tries to lock the same key, it will be stalled until the first process has unlocked the same key.

You may need to use these functions to ensure that you get valid data when exchanging data between your main program and a thread – otherwise it’s possible that the thread could wake-up halfway during your data copy and change the data – so the data you end up copying is incomplete, or invalid.

WiringPiMBS.pullUpDnControl(pin as Integer, pud as Integer)

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
method	WiringPi	MBS Linux Plugin	15.3	❌ No	❌ No	✅ Yes	❌ No	Desktop, Console & Web

This sets the pull-up or pull-down resistor mode on the given pin, which should be set as an input.

Unlike the Arduino, the BCM2835 has both pull-up an down internal resistors. The parameter pud should be; kPUD_OFF, (no pull up/down), kPUD_DOWN (pull to ground) or kPUD_UP (pull to 3.3v) The internal pull up/down resistors have a value of approximately 50KΩ on the Raspberry Pi.

This function has no effect on the Raspberry Pi’s GPIO pins when in Sys mode. If you need to activate a pull-up/pull-down, then you can do it with the gpio program in a script before you start your program.

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
method	WiringPi	MBS Linux Plugin	15.3	❌ No	❌ No	✅ Yes	❌ No	Desktop, Console & Web

This performs a simultaneous write/read transaction over the selected SPI bus.

Data that was in your buffer is overwritten by data returned from the SPI bus.

That’s all there is in the helper library. It is possible to do simple read and writes over the SPI bus using the standard read() and write() system calls though – write() may be better to use for sending data to chains of shift registers, or those LED strings where you send RGB triplets of data. Devices such as A/D and D/A converters usually need to perform a concurrent write/read transaction to work.
