– replace the files libwiringPi.so.1 and libwiringPi.so.1.0 on the KUbuntu /usr/local/lib from the one found on the raspi.

is that what seemed to be a lost cause is now finally in English for you to enjoy. Hi Gordon. Copy of the Makefile… not sure where the archive is supposed to come from. The first hurdle is interfacing the servo – you’ll need a driver of some sort to boost the Pi’s 3.3v 14, 15, // UART – Tx, Rx Struggling to think why plugging in a Wi-Fi adapter would upset the GPIO. If you really do need millisecond accuracy (and a relay probably takes a good few mS to move!) for (c = 0; c %9.4f samples/sec \n”, 1 / (((double)(now – then) / 1000.0) / (double)(B_SIZE))) ; I agree a full C solution is in order. Please refer to the contribution guidelines for more information. As the bulk is C code, compile and run it on the pi to get a usb HOST interface on the pi. You could handle the decoding of the 6 inputs in a C program, then write the values to shared memory for example (but I don’t know if Python supports shared memory – I’m not a Python programmer). I don’t know C enough, but it would be great if the 2 libraries could be combined.

else I use edge detection the both directions and record the time differences to do the decode.

You’ll need to reboot the Pi to get them back into serial mode. Although there is some margins to the pulse timings – the Raspberry Pi nanosleep function isn’t accurate enough. I have actually written a new module in wiringPi for servos, but I know it will suffer from the same jitter my softwarePWM does. status = 0;

writing manifest file ‘wiringpi.egg-info/SOURCES.txt’ #ifdef __cplusplus Will update it later today. #ifdef __cplusplus You may want to have a look at my LED driver program to switch your program into high priority though – have a look here: https://projects.drogon.net/7-segment-led-display-for-the-raspberry-pi/. How do I have to write the BCM GPIO in C? The whole staff that worked on this project invested hundreds of hours upon, hours into this game. reading manifest file ‘wiringpi.egg-info/SOURCES.txt’ uint8_t spiData [3] ; if (chan == 0) static int pinToGpio [] = You might want to start with minicom on the Pi side of things – it’s a serial terminal emulator program – run it and configure it to use /dev/ttyAMA0 at the baud rate you want and off you go. I have a version of i2c-dev.h installed from package linux-api-headers but it doesn’t define the required functions. #define I2C_DATA_DELAY_OFFSET 0x18. Miles better than the OS file system method — get some really good speed. you’ll probably have to write your own software on the Pi side of things to help you – wiringPi has some serial support in it though – just check the web page, but you’ll also need to check the pages for the devices you’re trying to talk to…. These are the I2C pins on a Rev 1 board – on a Rev 2 board they’re still I2C, but are now internal to the Pi. Hi Gordon, Wiring is the core of the input and output for the Arduino, so I thought it would be good to replicate that functionality (or a good usable subset) on the Raspberry Pi. https://github.com/mshmelev/RPi.I2C.Net * /tmp/ccYLGr7I.o: in function ‘main’:

mem_tmr, echo 1 > /sys/class/gpio/export Big Thank You and Well Done! Hardware wise – The main issue is going to be the voltage difference if you’re interfacing peripherals – typically 5v for the Arduino and 3.3v for the Pi. Right. Because they’ve now changed and becuse the foundation have changed pin function between the Rev 1 and Rev 2 boards, I would not rely on the state of any GPIO pin at boot time. (Although looking at the audio drivers might be helpfull here!).

So if the generic register read command isn’t working, then I wonder if there is some other communication issue – however i2cdetect finds it OK. running install I’m just providing wrappers round the standard kernel drivers – and there are some issues there that I’m aware of – the Pi doesn’t like clock stretching, so if the device is doing that operation to dealy the ack back to the Pi, then it will probably fail. But now when I download it I can’t decompress it; I get “gzip: stdin: not in gzip format”. | 16 | 15 | 10 | RxD | ALT0 | High | Since the game was the last by Enix, we wanted it to, have the feel of a classic Dragon Quest game. I wired up as you describe and still got the 2 counts from each press with your code ‘wfi.c’ so I extended your delay to 1000 microseconds which cured the ‘switch bounce’. The game is huge and full of randomness. You’ve been spotted! I’m great fan of your library. make: *** No rule to make target `/usr/local/lib/libwiringPi.a’, needed by `gpio’. For which I had to change gertboardAnalogRead: int gertboardAnalogRead (int chan)

Thanks Gordon,

Use the pins page: http://wiringpi.com/pins/ to make sure you’re using the right pins. } ; Thanks again for the library and the nice easy install , Your quite possibly right. I don’t think you’re quite comprehending what I posted earlier…. of defeated monsters and combine them to reform your monsters into new forms. exit (1) ; one_pulse = 0; will make pin 18 an input and set the trigger to a rising edge. Character. You’ll need to fetch the BCM ARM Peripherals manual too – that’ll help you find it. Word (32-bit) offsets vs. byte (8-bit) offsets! Guess you might need to to correct the signal back into the Pi, so 2 of them – might also provide votage buffering if the PIC system is at 5v too…. Your library worked great for me, untill I have installed the EW-7811Un WiFi adapter. ), So really the way is to use a peripheral device – there is the on-board UART (but I’m assuming you were already using that hence the need to bit-bang) but if you needed a 2nd, I’d probably look at a USB device myself…, (If you’re not using the on-board one, but want to, then look at the wiringSerial code for a simple way to get going with it), Yeh, as I expected. The best resolution I can get is almost 100us which is so much slower than the Arduino which can manage about 4us with delayMicroseconds. Would like to get it running but not finding any good src.. all is for the arduino and not sure if this is a good Wire.h replacement…, WiringPi’s functions doesn’t work when I compile it with OpenCV…. (in that scenario, I hard-wire the R/W pin to ground!) | wiringPi | GPIO | Phys | Name | Mode | Value | You may not realize how, much text is in this game while you play it, but there are variations on, practically every line spoken by the members of your caravan (depending, on their age, gender, and job). What do you want to do with it? After a ctrl-C and executing it again it works OK! I’m programming with Lazarus/Freepascal on my Pi and using Rpi_hal to read/write the GPIO of a PiFace … My code is at https://github.com/khandharjay/Rpi-I2C. If nothing happens, download Xcode and try again. # Required-Stop: $network wiringPi: Debug mode enabled

It's from the original, game. Yes, that’s the code from Mikes wand – I’ve had a look at it recently and it’s possibly better for very short delays. echo 1 > /sys/class/gpio/unexport so I have a little ‘scope on order myself and am going to have a play with it soon to better understand how it’s working. Now my Pi will be almost as useful as my Arduino!

combo_pulse = one_pulse + two_pulse; I’ve looked over the RPi GPIO manual and cannot figure out if this is normal, while I believe this could be a reason or symptom of what is wrong with my Pi. Thanks for that. // previousstatus = status; adventure in which he becomes the leader of a caravan.

I can launch the script manually via ssh and it works. #endif No joy though. I’ve noticed a few issues with some new code I’ve included. The pin numbers are BCM-GPIO pins. 15 Jan 2013) on Arch Linux. No, you need to use serialPutchar – nul is 0 and that’s what terminates strings in C. However, you can use write() – the file descriptor returned by serialOpen is a standard Linux file descriptor, so if you have a buffer of arbitary binary data, then: is what you need. any helper library?

The routing settings of controllers can be done through macros or configuration file. Hi, I just wanted to voice my support for what you’re doing. I’d also use minicom to check it initially before moving on to programs. But when it comes to more source files, which should be build to a single program, I don’t know what to add to the Makefile… +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ # Required-Start: $network $syslog the Pi has pull down as well as pull-up internal resistors and they’re activated in a different manner, so there are a few subtle differences like that. Is IO by default in output or input mode and if output mode, is output HIGH or LOW? gpio -g mode 15 out ; gpio -g write 15 0. that would put them both to 0v. -Gordon. { if (wiringPiSetup() == -1) What do you think of the idea of sending me the C source code and I’ll have a go at converting it to C#?

I would really rather not use a chain of relays or a DC/DC converter, but that might be my only option. they're used to gather information about the pages you visit and how many clicks you need to accomplish a task. -Gordon, thanks for sharing. its working fine for 5-10 minutes after this an if ((unsigned long)timer_mem % PAGE_SIZE) A3: For more than 4 years Mike hosted Threat Dragon on his personal github area, and in mid-2020 he felt that the time was right for it to migrate to the OWASP organisation github space. After reloading ALSA I’m back to testing sound and my ‘logic’ now has the interesting feature of playing ‘sound’ on the HO track voltage. while( (current_count – count_at_start) >2)); { In the example, the controller returns a Hello, world! So when running it at high priority what you have done is to efectively stop all other user-land processes running, however, the delayMicroseconds() call will deschedule your program and then allow them to run again – until your program is ready to run… However Linux doesn’t guarantee that delay – it’s a minimum of that delay and may be more….
