Re: Gigatron ASIC and the Gametron Handheld

If anyone has a Panelook account and can help me download it, it's the Epson 2.8'' L4S00242P00 (https://www.pan...

Re: And again a new Gigatron fan

Welcome Hans! Nice work! "soldering is relaxation for me" - I totally get it! It's exactly the same situation for me. Nothing beats the leaded solder fume high:P Doubling the clock in hardware is the easy part. The VGA timing is tied to instruction count, and deviating from the current architecture ...

Thanks! If I ever get to that point, you will be the first to know! Probably because it'll be running software you wrote:P

Re: Gigatron ASIC and the Gametron Handheld

Please see updates to OP and check out this YouTube video. https://www.youtube.com/watch?v=8e-uxF432BU I'm on a quest for more native 640x480 display options for the Gametron. The one I'm using now is consuming ~650mA@5V just for the backlight! I'm thinking a 3.5" display would be a good size. If an...

Re: Gigatron on an FPGA

As an update to this thread. Interfacing directly from the FPGA to a native 640x480 display is very much possible, but any deviation from the native resolution of 640x480 will require non-trivial effort on the software side because the VGA timing is derived from the number of instructions executed a...

Re: SDCard browser for Pluggy Reloaded:

Key things to watch out for 1) Install the SD card library (which you can do through Tools>Manage Libraries in the Arduino IDE) 2) Install the Pro Micro Board Addon for the Arduino IDE (https://learn.sparkfun.com/tutorials/pro-micro--fio-v3-hookup-guide/#windows_boardaddon) 3) When programming the A...
