[FluidNC PR#1443] New FluidTerm with STM32 Loader

FluidTerm for Windows now has an STM32 FLASH programming tool inside. To use it, connect a USB Serial dongle to the STM32 device with GND, 5V, Rx and Tx and set the device to boot mode by setting the BOOT0 jumper to 1 and the BOOT1 jumper to 0.

Run FluidTerm and connect it to the COM port associated with the USB Serial dongle.

Type Ctrl-S to get the ‘STM Loader Command: ‘ prompt. At that prompt you can type ‘-h’ for a list of commands. Common commands are:

-w filename Writes the contents of the named file to FLASH
-r filename Reads the FLASH into the named file

If you enter an empty command, it will connect to the device and display its characteristics.
