Yes, I did this after plugging the STM32 into the USB port. It did not show up in Device Manager Ports. Do any of the buttons on the STM32 board have to be pressed?
Yes, you have to keep the BOOT button pressed while plugging in the USB C cable to the STM32 board, to enter DFU mode. Check post #78 on page 4 of this thread, I pointed Bob around three months ago to a website that explains the STM32 flashing procedure in detail. Or ask on the STM32duino forum.
Thanks for the reminder @AndrewBCN. Looks like I skipped over that when I was scanning the thread to catch up on what I had missed.
I must say that Win10 is very fussy in handling the STM32 via USB, more often than not rejecting and refusing to talk to it.
Anyway, using reply #78, I managed to to get Blinky to work properly this time. I then loaded the ASCII program and got the following response in Monitor:
"ASCII Table ~ Character Map
!, dec: 33, hex: 21, oct: 41, bin: 100001
", dec: 34, hex: 22, oct: 42, bin: 100010
#, dec: 35, hex: 23, oct: 43, bin: 100011
$, dec: 36, hex: 24, oct: 44, bin: 100100
%, dec: 37, hex: 25, oct: 45, bin: 100101
&, dec: 38, hex: 26, oct: 46, bin: 100110
', dec: 39, hex: 27, oct: 47, bin: 100111
(, dec: 40, hex: 28, oct: 50, bin: 101000
), dec: 41, hex: 29, oct: 51, bin: 101001" plus a lot more...
So that appears to work.
I believe I am now ready to tackle the REAL program to control my GPSDSO.
