Steve the friendly fellow whom runs the site **broken link removed** was kind enough to modify his source code to work on the Unicorn. The GLCD looks awsome in reality, my photo skills for LCDs are minimal. **broken link removed**
Finally got around to having a play with this. The Graphic LCD is actually easier to initialise than the character based ones but a bit trickier to use. The really tricky bit is finding fonts. Managed to find a nice proportional one though. I'll post some code when I get time to tidy and comment it.
Hello,
Escuse me but I saw this article just now.
I would like to build this mini oscilloscope but with only the executable for PIC18f4550 I can not see how the connections between pic and GLCD.
Could I have the schema?
In the site of semifluid there are only connection to the PIC18F2550.
Hi,
I try but It don't works.
I loaded with my pickit2 the file .hex of this old post "18F4550 GLCD Oscilloscope DR1r1 - no bootloader, GLCD4550, 20MHz, bl" and I connected all as a scheme.
You can use this hex you have to load the boot-loader it doesn't mater if it said 18f2550 it will work
The PIC must initially programmed with the ‘SAC_tinybld18F2550usb _20MHz_115200_48MHz’ hex file to program the bootloader on the PIC. Then, using Tiny PIC Bootloader, the hex file can be placed on the chip using the Tiny PIC Bootloader frontend with ’12h 34h 56h 78h 90h’ in the ‘List of codes to send first:’ in the ‘Options’ menu. Please feel free to contact me if you have any problems.
The problem is solved with a bias created by a resistive divider and a capacitor.
Unfortunately it does not work the trigger and read of the frequency.
