Again, basic support will be to add code to set up the clock tree and perhaps add a few other things like linker script and startup code. I usually do this by creating a new project for the processor in the STM32CubeIDE and copy the needed bits over. So fairly easy. |

Thanks for the update. I was thinking for WiFi that it could be via SPI but maybe via UART would be simpler to setup. It will be easy to breakout one of the UART ports for WiFi as I believe this MCU also supports USB. Is that something you can add as well or should I use my own USB - UART interface? I read your comments for the STM32F446 discussion and need to take into consideration unique GPIO numbers for each input (interrupt). I guess I will be limited to 16 inputs (Limit, Control, peripherals and AUX In) |

It sure will, with luck the HC-05 driver code could more or less be reused as-is.
I supports USB and the driver does as well. So a USB - UART interface is not needed. Anyway, break out as many UART ports as you can - at least two. RS485, pendant, bluetooth/wifi...
Correct, except aux in pins does not have to be interrupt capable. An I2C port together with an interrupt capable pin might be nice to have, at least consider adding an EEPROM/FRAM footprint. The flash page sizes are pretty large in this MCU so writing settings etc. to flash will be rather slow. |

Awesome. I have been playing around with STM32CubeIDE and noticed that when I enabled ETHERNET and USB_OTG_FS there was a clock conflict that the IDE could not resolve. I think then that just using an external USB-UART will be the safetest option. I am thinking USART 1 & 6 or UART 7 & 8 as the pins for both as they are right next to each other (makes it easier for running PCB tracks). What would you suggest is the better option? For WiFi via UART, I assume there will be a requirement for an Interupt? |

Then you have to resolve it manually, I do it nearly all the time. Sometimes I have to accept a MCU master clock frequency slightly less than max allowed.
Use USB, it is by default faster that UART and that may affect laser engraving speed.
I guess so, at least it is required for the HC-05 module where a connection is signalled via an interrupt capable auxillary input. |

OK. Thanks for the feedback. Would you kindly advise what config options you select for USB_OTG_FS so I can then create the PCB design. I will also need to run an external crystal (HSE) to get the USB_OTG_FS to work. I will leave a spare GPIO for the UART channel in case I need it for interrupt. I will keep checking regularly to see when the build files for this MCU can be downloaded. Please let me know if you would like me to upload any config files (from CubeIDE) that you think will help with setting default pin mappings (for what I am currently setting up the PCB design) Regards and have a great weekend |

I'd support pledge for the option of adding wiznet The even better way were to design a nearly bare breakout with ethernet, usb, sd, flash on it. Somebody of you in the pipeline of such a thing? |

That basically can be done by copying the low level code over from the F4xx driver and (re)test. BTW it is not a good idea to have ethernet and sdcard sharing the same SPI bus - it is workable but file transfer throughput will be severely limited, possibly by a factor of ten or more. |

Hi Team,
I have a conceptual design based on default pin mappings obtained from
STM32CubeIDE, (Ethernet via LAN8720 interface IC, Onboard USB, USART 6 for
Future WiFi, SPI [4] for SD Card). Is it possible to create the relevant
build / linker files with these as minimum defaults? I can also provide a
full Map file if that also helps.
Cheers and have a great day
George

Also, what is the possibility of adding support for STM32H746ZIT6 MCU? It looks to closely replicate the STM32F7xxxx based MCU's except that it runs up to 480Mhz clock speed. If you found the F765VGT6 main.c file useful I can zip and send the H746ZIT6 main.c file as well. Cheers |

There is a H7 driver here. Currently supports H743 and H723 MCU's (the README needs an update to better reflect the supported boards). You can also see what's supported in the Web Builder. |

Thanks dresco. I am happy to provide any files that have already been generated within STM32CubeIDE (specific to Ethernet, USB-OTG-HS, UART and SPI ports) if there is a chance you could create the relvant build / linker files. Happy to maintain this conversation into your repo as well if you wish. Also my current design is using the H743ZIT6 MCU (typo above). Cheers |

The sdcard folder is empty/missing?
The keypad folder is empty/missing? Missing files/empty folders could be due to the submodules not beeing downloaded correctly.
My bad, I experimented with OLED support a while back and have left a reference to the code in the configuration, delete it here:

Thanks for your reply.
I have followed your instructions and deleted the OLED reference and have
created a Keypad folder and populated it with plugin code. I have also
re-downloaded the SD Card plugin code but I still get a SD Card error.
I have attached a few screenshots for your reference.
Regards and have a great day

What is "first defined here"? It should be named, e.g. a function. BTW I do not get this error, perhaps you should try to clean the project, or build without SD card support to see if it goes away. |

Perfect. I only needed to add the keypad and oled folders and then it was completely error and warning free. Do I need to add a folder for the Trinamic plugin? Cheers and have a great day |

Just quickly, do the Probe and Safety Door also need to be assigned to AUX (Input) ports? Cheers George |

Yes, when not needed they are not claimed leaving the pins free for general use. Bind them among the highest numbered aux pins. |

Would you kindly advise if you can add support for I2C4? I2C4-SDA - GPIO D13 I have also been enabling more options (in my_machine.h file) and was curious if you are interested in the warnings that have been thrown. Regards George |

try this, not tested:
Yes and no... Newer versions of the compiler is emitting warnings that are patently wrong. And I have fixed some (unused variables). |

OK. New file seems to have allowed code to compile (with #define I2C_PORT 4) I then tried to enable Keypad and then it threw an error: Description Resource Path Location Type I do have Strobe defined but is greyed out #if KEYPAD_ENABLE I then changed to #if KEYPAD_ENABLE I did notice that the STROBE is via an AUXINPUT so I added it in but still get the same error I suspect I may not have correctly written this for the STROBE.

I am also looking at the STM32F765VGT6 (100 pin, 1M Flash, 512K RAM, 216MHz). I assume that it will be fairly easy to add support for this specific MCU with Ethernet, WiFi compatability, allow WebUI and to use HSI / LSI clocks?
Cheers
George
