NanoVNA-H rev3.7 and NanoVNA-H4 rev4.4 Replacing NXP SA602A with ZeeTK NE602A.

Firmware synchronization 1.2.43
Due to the discontinuation of NXP SA612A, we started to produce compatible chip ZeeTK NE602A, but due to the different chip manufacturing process, there is a slight difference between the two in the use of harmonics, new compatible ZeeTK NE602A NanoVNA-H rev3.7 and NanoVNA-H4 rev4.4 version hardware schematic. Using the SJWCH5351 (formerly SMC5351 renamed) as a signal source, it can operate down to 600 Hz. New hardware improves port isolation below 300 MHz.
NanoVNA-H-SI 2.8-inch NanoVNA-H using Si5351 as signal source
NanoVNA-H-MS 2.8-inch NanoVNA-H uses MS5351 as signal source, machine label hardware version MS ending
NanoVNA-H-ZK 2.8-inch NanoVNA-H using SJWCH5351 as signal source, machine label hardware version ZK or SM_ST ending
NanoVNA-H4-SI 4 inch NanoVNA-H4 using Si5351 as signal source
NanoVNA-H4-MS 4-inch NanoVNA-H4 using MS5351 as signal source, machine label hardware version MS ending
NanoVNA-H4-ZK 4-inch NanoVNA-H4 using SJWCH5351 as signal source, machine labeling hardware version ZK ending

Upload a revised version of nanoVNAsharp to be compatible with the new firmware. nanoVNAsharp has no features to update.

Synchronize the source code to DiSlord version 1.2.27

Use the modified chibios submodule from the 7z file.

Synchronize DiSlord's version 1.2.14 code

Update to DiSlord version 1.2.14 code for better and faster display.

You can check NanoVNA-D for detailed update logs.

Synchronize DiSlord's version 1.1.01 code

Synchronize DiSlord's version 1.1.01 code, including admittance display and remote screen.
The use of MS5351 as a replacement for Si5351 is officially supported from this release. It can be modified via CONFIG>EXPERT SETTINGS>MORE>MODE.

The released firmware file name contains SI with the initial value using Si5351 and the file name contains MS with the initial value using Ms5351.
No matter which firmware, you can still modify it through the EXPERT SETTINGS menu.

Sync DiSlord version 1.1

Adjusted support for MS5351M
6x10 fonts look good on 2.8" NanoVNA, not compiled bold font version for 2.8".

Synchronize DiSlord1.0.71 version

Synchronize DiSlord1.0.71 version,
Now you can set the time through the "Expert Setting" menu.
Both the newly sold NanoVNA-H Rev3.6 and NanoVNA-H4 Rev4.3 have installed a 36.768kHz crystal, and the LSE can be used to keep the time correct after shutting down.
Add a 6x11 font version to the 2.8-inch NanoVNA-H to enhance readability as much as possible while maintaining dual-column display. Thanks to DiSlord for providing the new font file.

The NanoVNA-H update file containing B in the file name uses 7x11 bold font, and the file containing L uses 6x11 light font.
NanoVNA-H4 uses a larger screen, which can display 7x11 bold fonts well. Only the bold font version is available.

1.0.70

1.0.69

Based on the source code of DiSlord version 1.0.69, merge the source code of NanoVNA-H and NanoVNA-H4, which can be specified by TARGET when compiling. NanoVNA-H uses larger fonts, the display layout is adjusted for larger fonts, and you can set whether to use large fonts on NanoVNA-H by USE_FONT.

1.0.45

Modified based on DiSlord version 1.0.45 firmware. I uses a larger font similar to tinySA to display the menu and Marker point information, so the AA version is no longer provided.The default si5351 harmonic switching frequency is modified to 290MHz to ensure that si5351 can work normally in most cases. On the NanoVNA-H rev3.5 version, I tested that it can still ensure good measurement accuracy up to 1.8GHz, so this version allows the maximum frequency to be modified to 2GHz. If you want to get the latest features, you can start compiling from DiSlord's NanoVNA-D project.

NanoVNA-H4 version compiled on Feb 21, 2020

This update file is only for the 4-inch version NanoVNA-H 4 ! ! !
