![]() put your main code here, to run repeatedly: put your setup code here, to run once: Hey, I tried using the ReceiveOnlySoftwareSerial library for my project where I need to read from 9 ID-12 RFID readers, but I’ve run into a problem where it only reads from the last port i call during setup. Makes it so the RA1 can read the value of the tags, but when the line is included the RA1 doesnt output any data.Īlso, I know its bad form to duplicate code, but I couldn’t get it to work by just passing the serial as an argument to a general method. SoftwareSerial (including the read-only version) is based on pin-change interrupts. CoolTerm is a simple serial-port terminal application (no terminal emulation) that is geared towards hobbyists and professionals with a need to exchange data with hardware connected to serial ports such as servo controllers, robotic kits, GPS receivers, microcontrollers, etc. It will never be a great success in reading multiple ports at the same time, because once a receive starts it keeps interrupts off so it can do a read with timed intervals. There is a method "ReceiveOnlySoftwareSerial::listen()" which makes the current instance be the one that is listening for input. Everything was working just fine, until I recently did some changes. ![]() There, a very useful program called 'CooltTerm' receives the data and saves it into a. You won't, of course, know which one to listen to at a particular moment… After a certain time (standard is 4h) the results are sent to a PC. You have a Mega, I presume, which can handle 4 hardware serial ports, plus you could add a SoftwareSerial one. Connect the Binho Nova to your PC using the provided USB cable. If you want 9 ports you are probably better off making up a board with 9 x Atmega328P on it (they are only about $3 each for the raw chip after all). Step 2: Connect the Binho Multi-Protocol USB Host Adapter. For my final project, I made a neopixel smart mirror that used a camera as an input device to display the image data it took onto neopixels.You only need a couple of decoupling capacitors (per chip) and a pull-up resistor preferably for the /Reset pin. This “mirror” incorporated a wooden backboard milled on the Shopbot, laser-cut wooden frames, casted LED covers, a vinyl sticker, and a 3D printed camera case. You can view my summary slide and video below:Īdditionally, I used modified satshakits that communicated with each other to take pictures with the camera and send the data to the neopixels. In week 13, I decided I would publish my work under a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0) License. This was a result of my Neopixel Smart Mirror being inspired by another person’s project, in addition to the fact that it is intended for personal use and is a creative display, so I will not attempt to sell it or gain any profit off of it. This license allows others toĬopy, remix, and share the material as long as they give credit to the creator, refrain from using the project for commercial purposes, and apply the same license on the transformed project as the original.
