Cheap and simple USB to HD44780 text LCD interface
Home Page: http://www.harbaum.org/till/lcd2usb/
Hello,
Which drivers should I use for Windows 98?
I am having a hard time finding the proper drivers.
I habe already tried to install an oder Version of libusb32 0.1.x
Thanks for help
I cant't open it with my EAGLE
Thanks for the work done and the provided schema and source code.
I try to connect the display 1x16. When I run the test program (in OS X) I get the result in the console:
MacBookPro:testapp zvp$ ./lcd2usb
-- LCD2USB test application --
-- (c) 2006 by Till Harbaum --
-- http://www.harbaum.org/till/lcd2usb --
Found LCD2USB device on bus 020 device 022.
Echo test successful!
Firmware version 1.9
Installed controllers: CTRL0
Keys: 0:off 1:off
But only the first 8 positions on the left are used on the display, the remaining 8 are just empty. If I start LCD Smartie in Windows, everything works, but the situation is similar - only the first 8 characters. What could be the problem?
would it be possible to adapt this project to run with an atmega328p? more specifically with an arduino pro micro/mini?
how hard could it be to do this?
I know the clock is different so some changes might need to be made...
the pcb would need to be redesigned i know this too.
thanks for any helpful info!
I would be happy, if I get the software running.
My Environment:
Raspberry Pi Model B Rev 2
Linux rasp1-buster 4.19.97+ #1294 Thu Jan 30 13:10:54 GMT 2020 armv6l GNU/Linux
I did:
sudo pip install lcd2usb
Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple
Requirement already satisfied: lcd2usb in /usr/local/lib/python2.7/dist-packages (1.2)
Requirement already satisfied: libusb1 in /usr/local/lib/python2.7/dist-packages (from lcd2usb) (1.7.1)
Now the 1602 RGB LCD is connected with the USB-Port
sudo python usblcd.py
Traceback (most recent call last):
File "usblcd.py", line 9, in
lcd = LCD()
File "/usr/local/lib/python2.7/dist-packages/lcd2usb.py", line 69, in init
raise LCD2USBNotFound()
lcd2usb.LCD2USBNotFound: Cound not find LCD2USB device.
I am shure its my fault. But I dont know where to look.
I hope, somebody has a soultion or a hint (or a URL).
Many thanks in advance.
Hi
Have you ever considered supporting some OLED 16x2 or 20x2 displays in place of regular LCDs ?
