Hello Group Members I have a SYSJOINT NanoVNA-F V2 that was working
perfectly until I tried to update the firmware to the latest version from
SYSJOINT, when I copied the Bin file to V2 it loaded, the green bar went
all the way to the left than stopped stayed there for a long time, I turned
it off than back on again the blue light stays on but the screen is dark no
display please help Thank You






Re: SYSJOINT NanoVNA-F V2

 

Yes I believe it is .4 for the?NanoVNA-F V2?according to SYSJOINT

Re: Clock Generator Si5351at 24MHz

 

Depend from used IF, 12k
More easy get this step.
IF depend from ADC speed, ADC from ... USB 48M


Re: Clock Generator Si5351at 24MHz

 

You will likely want to pose this question on the "NanoVNA-F & DEEPELEC" and/or the "NanoVNA V2 Users Group" groups.io forums.

Hello,
Does anybody know why in the design of NanoVNA-f V2, a 24 MHz crystal is used for Si5351A? In the datasheet of Si5351A it is mentioned that the chip shall be driven by either 25 or 27 MHz crystal.

Remember: Whinders is inherently low quality, and tends to get things wrong. *Always* question what it claims!

On previous attempts windows had reported that the drivers installed were the correct ones !

Again,thank you.

Re: Question on remote use of NanoVNA

 

FYI, I acquired a multifunction TL-WR902AC Travel Router and set up a Lan using it router mode (no internet). This works fine under Windows 10 on a Lenovo Laptop but didn't on my Toshiba running Windows 8.1. I can only speculate why.

Re: Problems Upgrading firmware on nanoNNA H4.

 

David:

See
/g/nanovna-users/message/20899

The procedure shown there tells Windows how to see the "STM device in DFU mode".

Hope this helps,

Re: Pinned posts for current versions?

 

I use Thunderbird as my email client, I just tag all the software update posts with an appropriate color so they standout.

Other email clients provide the same function.

May I suggest that there be a pinned post at the top of the message list for the current version of firmware for each of the various forms of the NanoVNA?
It's getting a bit confusing.....

Re: Which version of the firmware supports rotary encoders

 

³Ù³ó²¹²Ô°ì²õ£¬

I've recently taken some time to add a rotary encoder and the basic functionality is implemented, the menu bar scrolls well, but the trace scrolling shows that the marker points are moving too slowly.

I use PA1 and PA2 as the channels of the encoder, and I use interrupts to implement the function.

static const EXTConfig extcfg = {
{
{EXT_CH_MODE_DISABLED, NULL},
{EXT_CH_MODE_FALLING_EDGE | EXT_CH_MODE_AUTOSTART | EXT_MODE_GPIOA, extcb1},
{EXT_CH_MODE_FALLING_EDGE | EXT_CH_MODE_AUTOSTART | EXT_MODE_GPIOA, extcb1},
{EXT_CH_MODE_FALLING_EDGE | EXT_CH_MODE_AUTOSTART | EXT_MODE_GPIOA, extcb1},
{EXT_CH_MODE_FALLING_EDGE | EXT_CH_MODE_AUTOSTART | EXT_MODE_GPIOA, extcb2},
{EXT_CH_MODE_DISABLED, NULL},
{EXT_CH_MODE_DISABLED, NULL},
{EXT_CH_MODE_DISABLED, NULL},
{EXT_CH_MODE_DISABLED, NULL},

}
};
