I wanted to connect replacement LCD to the original LCD connector, with no "ugly hacks" like interfacing with VGA connector and other workarounds. The original LCD used 9-bit TTL RGB interface (3 pins for red, 3 pins for green, 3 pins for red), which...

Detecting and identifying a card As stated in an earlier log, the card insertion is detected by grounding the pin *CD. But this is not enough to make the scope believe he have a know card inside him. You need to indicate him what type of card was inserted....
I'm going to create a stand-alone PSoC project to use the PSoC to read SD cards. I'm going to start with the hardware defines for this project (which should leave the Z80 hardware pins unmolested) and just not download code. For the software piece, I...
The following has been implemented:Allowed for communication with Claw machine mode via RS232 using the following menu structure:prog Enter into programming mode. Game play will be suspended after push button routine is finished (normal claw machine...
Cant add text from iceweasel, ok. Updates will be few between as I dont get to the computer with chrome on it much.So far I have a good start on the usb control part of the firmware, I have a working DAC code sample. The DAC I chose, ( PT8211 )...
The 6n137 worked great for isolating the serial at a ttl level, full baud rate isn't a problem. Cant say the same thing about hackaday.io when used with iceweasel.I will made a point of posting the isolator schematic (its pretty straight forward...
So, I been wrestling for quite a while with the pwm genorator trying to get rid of little glitches and bounces and ringing that came up during final assembly. The final straw was a 40mv, 5Mhz ring that caused the pwm comparitor to output a ring that...
So, I decided to build this 1 channel version of the power supply, and although I'm not directly documenting it, its research is going to be used in THIS power supply.What I did today: (its not tommorow till I'v slept)For the 1 channel supply I worked...
I've been slowly chipping away at the edges of a dilemma. I've been very comfortable using Dave Dunfield's MON09 monitor program for this project. It's a really nice full-featured monitor that works great, and took almost no effort to port to my hardware...
To convert the low voltage (~1.3V) custom protocol output by the dial indicator to something that will be readable by the computer I have chosen to use a PIC microcontroller. Specifically, I will be using a PIC12F1822 because it's cheap, small, well...
Here is the very simple circuit I am using for the PIC chip which converts unique protocol from the dial indicator to regular UART signals that can be read by a USB TTL adapter (serial protocol @ 5V). This will probably the first circuit I try making...
