Scrolling Text on Oscilloscope – Even the Elementary Students Can Do It Too!

Oscilloscopes are one of the most familiar electronic components, which most of the home hobbyists might have got in touch with it, at least once in their life! Ok, maybe you’ve been done multiple experiments with Oscilloscope before, but have you ever try to use it for scrolling text? Yep, even though it’s not a new method, however, it would give you a several “surprises” that you’re not expected at all! So, it’s a very simple project that based on a PIC micro PIC16F628A. Why we said it’s a very simple project? It’s because it only have one component plus the battery! Basically, the main purpose of the circuit is to show a scrolling text on oscilloscope. In this case, those characters, which are going to be displayed can be stored by user in EEPROM. The first EEPROM location with 0xFF value is considered as the end of text. The last EEPROM location with 0x7F is containing the scrolling speed in 20mS steps. Normally, a jumper would be placed between the pins Vdd and Vpp, after programming the micro via… Continue reading

The Scrolling Text on Oscilloscope Based on PIC16F628A

Many of you here might have heard about the oscilloscope before, or maybe have frequently using them in your daily electronic project! However, have you ever used the scrolling text on oscilloscope? To be honest, it’s nothing different, except you are using the scrolling text on oscilloscope. For your information, the project is built with only one component, the Microchip PIC16F628A! You must be shocked and wondering, “Oh, is it possible to build a device with one electronic component?” Hehe, anything is possible, as long as you knew the proper ways! When you’re using the scrolling text on oscilloscope, the characters that are going to be displayed are stored in EEPROM. Normally, the first EEPROM location with 0xFF value is considered as end of each text, while the last EEPROM location (address 0x7F) contains the scrolling speed in 20mS steps. You must know that the configuration word for this application (address 0x2007) is 0x3F34. Hence, you need to place a jumper between the pins VDD and VPP, after you’ve programmed the micro via the ICSP connector. Mostly, the oscilloscope will… Continue reading
