Remora 1.0.0_rc released for testing

I'm pleased to share that development work to support STM32F4 based controller boards has come to the point where a release candidate for wider testing is ready.

Today I have pushed 1.0.0_rc to Github. The release package is available  github.com/scottalford75/Remora/releases/tag/1.0.0_rc

Currently there is a difference LinuxCNC Remora component ( github.com/scottalford75/SKRV2-Mbed-OS5/tree/main/Remora ) that must be used for STM32 boards. I'll start work on a common version with command line parameters to select which MCU type for the controller board. The SPI comms for the STM32 is 4 times as fast and uses a different Chip Select regime.

There has been some significant code base changes to allow for support of LPC176x boards and now STM32F4 boards. Testing has been performed on SKRv1.4 and SKR2 boards, but bug testing is appreciated before the final release.

The 0.1.0 release for LPC176x based boards has been captured  github.com/scottalford75/Remora/releases/tag/0.1.0

I will take a look at my config tool and see what needs to be changed.

Now I got to order a board to test with. Just have to pick one.

Hi Aaron,

The only updates should be for the TMC drivers and the new Motor Enable module for the SKR2.

Now that we have STM32F4 support, there is a lot more boards to choose from.

Is this change consistent between the 2 versions? Lpc vs stm33?

I tested on all the STM32F4 boards i have and everything is working great exept on F401 and F411 (not the same frequency)
You did a really great job Scott, Thank you !
i m already looking at how to port it to stm32H7 with a higher frequency, H7 is supported by OS 5, it should be easy.
Do you plan to port it to STM32F1 ?

Hi, and thanks for the feedback regarding the 401 and 411. I'll need to note that the 407 is the supported chip version.

Porting to other STM chips will be more straight forward now, and I'm already looking into which STM32F1 board to get so I can start on this as well.
