Do not throw slippers, I’m noob. I’m tryng to find similar node like “digitalWrite” in Arduino IDE. Now i find only i2c and UART nodes, but this does not fit. I want to learn to control 7segments displays with 74hc595, but without arduino IDE. Please dont send me to google, just ignore, if you dont want to help. ---

Hi kolanzev I have already written a library for just this 😄 Install in XOD and you are good to go. [bradzilla84/74hc595](https://xod.io/libs/bradzilla84/74hc595/) not sure how to install? [https://xod.io/docs/guide/using-libraries/](https://xod.io/docs/guide/using-libraries/) ---

Hi again, it does not work, i crash all my brain. " Checking Arduino dependencies… Library “ShiftRegister74HC595” is missing Arduino dependencies missing You have to install these libraries first: “ShiftRegister74HC595"” Through “File/add library” library does not setup, “Simsso/ShiftRegister74HC595”, library not found. ---

Yep when that message comes up there should be a button in the bottom right hand corner for install xod will take care of the rest for you. 🙂 ---

Ow… Yes, it starts working, but my program does not work. I tryng for first time set random sequence in node hc-595-pack, but 7-segment dysplay segments are all OFF, or all ON, what bit or sequence or bits it do i dont know. That is my program: ![00](https://canada1.discourse-cdn.com/flex027/uploads/xod/original/1X/b9d80c11d6a1db0223cce53b397424b25b061a5d.png) Dysplay connection is correct, because this code works az it must: ```auto int latchPin = 2; //pin 12 on the 595 int dataPin = 3; //pin 14 on the 595 int clockPin = 4; //pin 11 on the 595 void setup() { pinMode(latchPin, OUTPUT); pinMode(dataPin, OUTPUT); pinMode(clockPin, OUTPUT); } void loop() { //0 digitalWrite(latchPin, LOW); shiftOut(dataPin, clockPin, MSBFIRST, 64); digitalWrite(latchPin, HIGH); delay(1000); //1 digitalWrite(latchPin, LOW); shiftOut(dataPin, clockPin, MSBFIRST, 121); digitalWrite(latchPin, HIGH); delay(1000); //2 digitalWrite(latchPin, LOW); shiftOut(dataPin, clockPin, MSBFIRST, 36); digitalWrite(latchPin, HIGH); delay(1000); //3 digitalWrite(latchPin, LOW); shiftOut(dataPin, clockPin, MSBFIRST, 48); digitalWrite(latchPin, HIGH); delay(1000); //4 digitalWrite(latchPin, LOW); shiftOut(dataPin, clockPin, MSBFIRST, 25); digitalWrite(latchPin, HIGH); delay(1000); //5 digitalWrite(latchPin, LOW); shiftOut(dataPin, clockPin, MSBFIRST, 18); digitalWrite(latchPin, HIGH); delay(1000); //6 digitalWrite(latchPin, LOW); shiftOut(dataPin, clockPin, MSBFIRST, 2); digitalWrite(latchPin, HIGH); delay(1000); //7 digitalWrite(latchPin, LOW); shiftOut(dataPin, clockPin, MSBFIRST, 120); digitalWrite(latchPin, HIGH); delay(1000); //8 digitalWrite(latchPin, LOW); shiftOut(dataPin, clockPin, MSBFIRST, 0); digitalWrite(latchPin, HIGH); delay(1000); //9 digitalWrite(latchPin, LOW); shiftOut(dataPin, clockPin, MSBFIRST, 24); digitalWrite(latchPin, HIGH); delay(1000); } ``` Can you please make little tutorial for your library? Or any examples of realy working structure of nods for 1 dysplay, 2 dysplays, matrix 8x8, with a few shift registers? I am sure it will be useful not only for me. ---

This all is for week of learning. Trying to repeat 2-th scheme, in the latest version XOD there are problems( For example i dont know, what is node with “T” letter, guess it must be constant-number now. “En” - guess constant-boolean. To “EN” connector of square-wave may connect only one node now. Think in latest version its unrepeated. ---

if you want to create another sequence equal or similar below, create a new patch (rename to sequence2) copy all `sequence` content and paste in `sequence2`, then add the `new node` to the `main` ---

Hi there! Somehow the Compailer in version 0.32.1 always issues an error. Even if I set it up exactly the same as in the pictures above. Even with a simple circuit like this: ![aufbau_1](https://canada1.discourse-cdn.com/flex027/uploads/xod/original/2X/6/600e0db258acc45d275279b12ff904726713fb27.jpeg) With this Errormessage: " Compilation failed Command Process exited with code 1 The generated C++ code contains errors. It can be due to a bad node implementation or if your board is not compatible with XOD runtime code. The original compiler error message is above. Fix C++ errors to continue. If you believe it is a bug, report the problem to XOD developers." ---
