Up to now the workflow has been:
- write some test code
- remove the rom from the isa board
- put the rom into an eprom burner
- flash the new code
- put the eprom back into the isa board
- power on and see if it works
This takes a lot of time, and requires a lot of insert and removal of both the isa card from the bus and the eprom from the socket.
I started looking around the net for an eprom emulator.
I found one on a website called MyGeekyHobby
From the website:
EPROM Emulator is a tool that can temporarily replace an EPROM memory chip inside your "target" device. You can plug it into your computer and "upload" a new version of code in seconds (instead of removing, UV erasing, reprogramming, and re-installing a traditional EPROM chip).
I've been using this eprom emulator in my development of this synth. It is so convenient and fast. My turn around time to test new code went from minutes to a few seconds. Kris has done an amazing job offering this emulator to the community.
Now, to test new code, I simply compile the program and send it over usb to the eprom emulator. The eprom emulator will reset the cpu when the new code has finished uploading.
Kris has a python script to send the binary to the emulator, but I like working with GUI, so I wrote my own uploader.
This has all the functionality of the python script, but works with a click of a button. It is also cross platform for Windows, Linux, MacOS
