Release of stable firmware 2.8.0 / bootloader 4.0.0
« on: 09. February 2018, 18:05:04 »

Bugfixes:
- Reduced startup delay for CW RX --> TX switching, especially relevant for use with external keys/keyers.
- Fixed some out-of-bounds errors which may help to run the firmware more reliable
- Bootloader fixes unreliable switching off on some machines.
Features:
- High precision touchscreen press detection. Please calibrate your touchscreen (simply press on the touchscreen during startup).
- Dual waterfall / scope display with adjustable percentages Scope can visualize filter width (color adjustments in Display Configuration menu)
- Added support for ILI9486 based LCDs @480x320 (with parallel and the RPi-style SPI connection supported, see below)
- Changed, much more effective noise reduction algorithm now based on spectral noise reduction concepts.
- PSK31 / BPSK TX and RX using USB keyboard
- CW memories (not stored in EEPROM !)
- New font for frequency digits (only for devices with more than 512kb Flash, can be configured in Display Configuration menu)
How to get a new highres display:
You can get 3.5" 480x320 LCD kits which have same headers as HY28B or new 3.2" LCD used at mcHF 0.7 from DF8OE. Running on 480x320 gives waterfall and scope using full display width and all other elements are placed in a much smoother way. LCD screen looks much better on higher resolution. Please note, you have to run the display in parallel mode.
For those with mcHF & RTC (which demands use of SPI display connection:
In theory you can upgrade to use the RPi SPI ILI9486 displays available on eBay but due to the larger size and generally slower fill rate, the display is noticable slower as the parallel on the same UI board (and there is not much we can do here).
An important note for owners of 512kb flash size mcHF UI boards:
Due to the growing functionality of the firmware we ran out of flash capability of STM32F4 with 512KB flash memory recently. Firmware on the 512k machines can have maximum size of 512KB - 32KB ootloader - 32KB virtual EEPROM = 448KB. Chris, M0NKA has switched some time ago to 1MB STM32F4 - so there is no problem for those of you. But there is an amount of mcHF and clones with smaller flash out in the wild. The best solution would be to swap MCU to a version with more flash.
If you swap the MCU it is a good idea to spend some extra cents and use STM32F427/429/439 which have 2MB of flash and 256KB RAM instead of 192KB. But all those who do have 192KB RAM / 1MB flash can remain calm, too.
As already announced a few days ago, we provide two builds of the mcHF firmware now: the "full build" and a functionality-reduced one for 512KB MCUs. Right now only FreeDV is missing - but sooner or later we will scrap at the borders of small MCU again, then we'll have to cut off something additionally.
For getting more information please read the "operating manual" https://github.com/df8oe/UHSDR/wiki/Operating-Manual and
"Operating Manual Menu" https://github.com/df8oe/UHSDR/wiki/Operating-Manual---Menu in GitHub WIKI section.
You can find recent binaries and archieved ones at the startup page https://df8oe.github.io/UHSDR/

Bei der Auswahl einer geeigneten MCU kommt es nicht nur auf die Nummer des Prozessors an,
sondern auch auf die Buchstaben, die folgen.
Ich habe mal eine Tabelle mit den im mcHF verwendbaren STM32F4xx MCUs zusammengestellt.
Alle haben ein V im Suffix, d.h. sie haben das LQFP100-Gehäuse. Der folgende Buchstabe G
bedeutet einen Flash-Speicher von 1 MB, ein I bedeutet 2 MB :
Typ Taktfrequenz Flash RAM Besonderheiten
(MHz) (kB) (kB)
STM32F407VE 168 512 192 Das ist der Urtyp und sollte ausgetauscht werden
STM32F407VG 168 1024 192 Der wurde später benutzt und lässt sich verwenden
STM32F427VG 180 1024 256 more performance, lower static power consumption
STM32F427VI 180 2048 256 dito
STM32F429VG 180 1024 256 Mit TFT-Controller, wird nicht im mcHF benutzt,
STM32F429VI 180 2048 256 stört aber auch nicht
STM32F437VG 180 1024 256 more performance, lower static power consumption
STM32F437VI 180 2048 256 dito
STM32F439VG 180 1024 256 Mit TFT-Controller, wird nicht im mcHF benutzt,
STM32F439VI 180 2024 256 stört aber auch nicht
Ich würde also eine MCU F427VI oder F437VI nehmen. Aber die 429er und
die 439er gehen auch, Hauptsache, es sind VI-Typen.

Have loaded the .bin versions of bootloader 4.0.0 and fw 2.9.0 with ST-LINK on OVI40 UI 3,5" LCD, but the splash screen displays in small format 
Is there a difference in the dfu and bin versions?
regards

Hi Andreas,
Have loaded latest bl and fw on both the betatest V1.07 and the V1.08 boards with same result. Can't explain.

Thomas, I downloaded the BL and FW this afternoon from github resp. 4.0.0 and 2.9.0. I never downloaded something from the archive. The only possibility is I mixed up some versions locally, however the download times as registered during download/file creation do not confirm this. I will download again tomorrow and load again tomorrow making sure no mix up is made.
kind regards

Thomas, I cleaned up the lot. I downloaded the bl again and reloaded the bl using st-link just now. And it displays the small splash screen with fw 2.9.0
I have to go now.
question : is it safe to erase the chip's flash memory with ST-LINK
kind regards

I have downloaded the FW and BL from github today. I erased memory of the F7. Thereafter I used ST-Link to load BL and FW successively. At startup the SMALL sized splash screen is displayed. Thereafter 2.9.0 starts normally.
The matter is cosmetic but nevertheless it doesn't do what it should : display the splash full size. I wonder why.

Thomas .
Tnx for your response. Your picture shows the fw update via usb stick. I have been loading with the ST-Link. I therefore do not get the info as shown in your picture when updating the FW. But that should not make any difference in the behavior when starting up the OVI40 with power up. I understood from your earlier message that the splash screen shown with power up is displayed full screen.

In all my messages regarding the subject I have been referring to ST-Link used for loading. One picture cleared the whole misunderstanding. Sorry for the confusion.

Nothing wrong with your use of English. I should have come to my mind earlier that the BL does not load the splash screen. Thanks for your help.

!! But if none of the two sticks up after the first try all will be cleared little later. By words, pictures, videos...
