FV-1 Project template

This is a project template with which you can start coding for the fv-1 chip right away, in assembler. The toolchain.sh script provides a complete open source toolchain. There is a Makefile based build using this toolchain, but the toolchain functions can also be used anywhere of course. For mac and linux.

Build Dependencies

The assembler - asfv1

build from source: https://github.com/ndf-zz/asfv1

or

pip install asfv1

The flash-tool - ch341eeprom

https://github.com/command-tab/ch341eeprom

run make it should just work, terribly simple program.

Hex2bin Converter - srecord (optional)

This is not required when using the asfv1 assembler as it already produces bin files.

port install srecord

Build

To build switch into dir src to execute the makefile targets

Makefile Targets

make flash - Build and upload all the 8 programs
make all - Only compile all the 8 programs
make erase - erases the rom chip
make clean

Toolchain Setup

You dont need this for the makefile build, only if you want to use the toolchain directly from the shell.

source toolchain.sh to get the commands ()

• fvcompile
• fvhex2bin
• fvflash
• fverase

Test

If everything worked well, you should have a delay effect on program nr 0.
