Printer from calculator, part 2
Continued from part 1. The printer from the calculator is a neat toy, but we want a real USB printer. So, using my new STM32F103 CubeMX USB printer class for communication with the host computer and some tricky INT based … Continue reading
ARM:0018 STM32CubeMX hack – printer class device
This article is about printer class device for STM32F103 and STM32CubeMX. Somehow there is NO printer device class example in whole internet. There ar CDC or HID examples copied from same STM32CubeMX example with minimal explanation, few of mass storage … Continue reading
ARM:0017 – go to sleep clock
This is a “gamers” clock. It sits near the monitor and shows the real time and time computer is on. This is achieved using USB as power supply. Also, the same USB port is used to set the clock. Battery … Continue reading
ARM:0013 STM32CubeMX – USB HID keyboard
Now we will build a USB keyboard. This project is based on STM32CubeMX canned example, HID mouse (see previous article). But we will change mouse to keyboard. Both devices are from the same HID class. First we need to change … Continue reading
ARM:0012 STM32CubeMX – USB HID mouse
Next canned project for STM32F103 MCU using the cube- USB HID mouse. HID (human interface device) means it is the standard device compatible with all computers with USB ports. STM32CubeMX has all device descriptors and init procedures already built in. … Continue reading
ARM:0011 STM32CubeMX – Pin interrupts
Next tutorial- interrupts, keyboard (PS2 input) and USB COM port. I have a small keyboard in my stash. It was from some flop device made by Amstrad. This keyboard has a 4 pin connector and I had hoped that it … Continue reading
ARM:0010 STM32CubeMX- USB 2 COM dongle
This article is also an introduction, but this time a bit more practical- USB to serial port (COM) dongle. This tutorial will show how to create USB devices from “canned” software using only STM32CubeMX. For this example I used some … Continue reading
AVR USB printer device and teletype
I have old teletype printer T-63 (it is made by RTF in Eastern Germany, clone of old Siemens Teletype). And the idea is about connecting it as USB printer to our-days computer. Easiest way is to connect it using RS232 … Continue reading
ATMEGA USB 001
In older posts I mentioned, that I resoldered several ATMEL ATMEGA16 processors. So, I decided to build something usefull using this MCU. As this controller has more ROM and RAM, I decided to use only high level programming language- C. … Continue reading
