Base project for Game & Watch firmware.

Opening in STM32CUBEIDE

I'm a total noob when it comes to STM32CUBEIDE so sorry if this comes across as a stupid question. But I downloaded the files and since there wasn't a project file in there, I started a new project using the base.ioc file. The problem I'm having is trying to import the other files and getting the project to compile. Is there something I'm missing here on how to open this base project? I was hoping to get the project open and sent over to my unlocked G&W so then I can mess around a try to figure out how everything works.

Thanks

I made the firmware and your base project help me a lot. thanks.
This is the project I am working.

It is unfortunate that the communication port on the board is not outside.
I think it would be nice if a board with an improved version could be made.

Thanks again.

A full retrace WIP

Hey, just dropping in to say hello, and drop a link. Thanks for the inspiration.

Running from ITCM RAM instead of flash

I was trying to do the same thing as in the flashloader – to upload the .ELF to the Game & Watch only temporarily. So I copied the linker script from there, compiled the project and uploaded the .ELF to the G&W, however, I was greeted by a black screen and no sound. I opened an OpenOCD instance to see if the code was even running, and it seems to be stuck inside HAL_Delay(), constantly calling HAL_GetTick() (pc is 0x0000XXXX, so it is running inside ITCM!). It never seems to exit that function, so is it possible that the system timer is stuck?

As you might tell, I'm quite new to STM32 (or even bare metal ARM in general) programming, so it's possible that I'm missing something obvious. I am using drivers which were automatically downloaded by retro-go.

Make: ...will not fit in region ...

i've got error compilation when make base main:

High voltage on VCC rail (discussion).

I'm bringing the #1 discussion here so as not to derail it from the original topic.

Adding a license

We should add a license to this project, MIT maybe?

Drivers directory

I wasn't sure where to get the Drivers directory from as it isn't included in this repo. I ended up using https://github.com/STMicroelectronics/STM32CubeH7

Is this correct?

Any ideas on why HAL_LTDC_LineEventCallback and HAL_LTDC_ReloadEventCallback dont fire?

I wanted to try out using vsync interrupts to maintain timing in my game.
I've been trying for hours and I just cannot get HAL_LTDC_LineEventCallback and HAL_LTDC_ReloadEventCallback to fire.
I have found the global interrupt enable for LTDC and ive turned it on.
It just dosen't work at all, any ideas?

For audio ive used HAL_SAI_TxCpltCallback and HAL_SAI_TxHalfCpltCallback and they worked straight away!
