V6.0: Bugfix update for V5.0 and V5.1 when used on HW V2.81
Functionally identical to V5.1
Update V6.0: For HARDWARE V2.81 ONLY - Will NOT work on earlier devices.
Fixes issues that are only present on 2.81 devices loaded with V5.0 or V5.1.
V5.x loaded on older HW versions are not affected.
V5.x loaded on HW2.81 using original FPGA may not be affected, since most of these new issues originate from program support of full speed buffer mode, which is only available with the updated FPGA. However, 5.x/2.81 users with original FPGA should still update to V6.0.
V1.1 FPGA included is same as in V5.1, no need to update.
-Increased RAM allocation from 48K to 64K and stack from 8K to 16K. Fixes a variety of potential problems such as loss of meter functions or triggering issues after config file saves. (This breaks compatibility with older devices, which only have 48K RAM)
-Fixed an issue where the program would crash if loading a saved configuration file with a full speed sampling setting while in one of any of the OS modes if the saved configuration contained a long buffer mode XPOS value greater than a certain value.
-Fixed shifting ChA/B DC offset levels after engaging FFT or other functions while in full speed buffer mode, possibly leading to corrupted calibration data if saved.
Any future updates will consist of 2 separate versions: V5.x for pre-HW2.81 units, and V6.0 and up for HW2.81 units ONLY. I have several of the older version devices so I plan on supporting those with the same additions and fixes as the later one, if possible, apart from FPGA based functions such as full speed buffer mode. This will also allow future optimization for the older units, freeing up memory by removing unsupported functions.
For anyone interested, also included a config file reading utility (QUADCFG.EXE). Displays and describes saved configuration and calibration parameters. Built this to help me fix these recent issues with the program. Copy a WPT or CFG file to same directory as utility, type QUADCFG followed by a space and the name of the config file on a Windows command line. Will write a file of the same name but with a TXT extension with the information. If no config file name is supplied or utility is just clicked on, will load first WPT file found in same directory, or just display instructions on the command line if no WPT file is found. Can be used to check for config file corruption or just for informative purposes.
Works with any version WPT “style” file, should also work with early factory apps using WPT config extensions.
Re: HW 2.82 as seen in a recent post: Uses same SYS (1.64) as 2.81, unknown DFU. I would expect this to be compatible with 2.81 updates, but since I don’t have a unit on hand, I can’t verify. Perhaps some info will appear on the MiniDSO site, but don’t see anything there yet…
