# AT-VFD
|
|
Goal: Controlling a VFD with an Atmel microcontroller
|
|
<br>
|
|
Compatible hardware: [Princeton PT6302](https://pdf1.alldatasheet.com/datasheet-pdf/view/391603/PTC/PT6302.html), [OKI ML9208](https://pdf1.alldatasheet.com/datasheet-pdf/view/135132/OKI/ML9208.html) (note that in naming the PT6302 datasheeet is followed)
|
|
<br>
|
|
Project is work in progress, breaing changes might come in the future
|
|
|
|
## Using the driver library
|
|
Modify PT6302.h
|
|
- Re-define the macro `DISPLAY_DIGITS` to the number of digits on your VFD
|
|
- replace the pins in `enum pins` with th pins you have wired to the given controller interface pins
|
|
|
|
Include the PT6302.h in your application and use the functions to display whatever you want.
|
|
|
|
## Building
|
|
Use **either** [GNU make](#GNU-make) or [CMake](#CMake) whichever you're familiar with.
|
|
### Dependencies
|
|
The project uses `avr-libc` as well as `avr-gcc`, please install the packages neccesary. For building you need either GNU make or CMake.
|
|
If you're using CLion, it should automatically pick up on `CMakeLists.txt`, but you still need to modify it to your hardware.
|
|
|
|
### GNU make
|
|
Modify `Makefile`:
|
|
- Change `MCU` to your target microcontroller
|
|
- Change `F_CPU` to the frequency of your microcontroller's clock source
|
|
- In `CFLAGS` make sure that the path after `I` is where you have your avr c libraries
|
|
- `TARGET` should be the project name (or keep it as is, it doesn't matter)
|
|
- In `SRCS` replace `main` with your application's c and header files
|
|
- Change the avrdude command in `flash` to the device and port you're using for downloading the firmware
|
|
|
|
Then in the project directory run
|
|
```shell
|
|
make && make flash
|
|
```
|
|
to compile and download firmware.
|
|
|
|
### CMake
|
|
Modify `CMakeLists.txt`:
|
|
- Change `TARGET_CPU` to your target microcontroller (in the `set` statement)
|
|
- Change `F_CPU` to the frequency of your microcontroller's clock source (in the `set` statement)
|
|
- Put the full path to your avr c libraries int the `include_directories` statement
|
|
- Replace `main.c` with the name of your c source and header files in the `add_executable` statement
|
|
- Change the avrdude command in the custom targeg`FLASH` to the device and port you're using for downloading the firmware
|
|
|
|
Create a building directory for cmake and change into it:
|
|
```shell
|
|
mkdir cmake-build-debug && cd cmake-build-debug
|
|
```
|
|
Then compile, link and flash:
|
|
```shell
|
|
cmake .. && cmake --build . -t FLASH
|
|
```
