Re: Mini Serial Soft Tools V2.61 Download 37l
Ingelore Clason
I'm running Windows 7 and MPLABX v1.95 on my PC. I have tried restarting my computer, disconnecting and reconnecting the PICKit2, flashing the PICKit2 to the latest firmware, running MPLABX as administrator, and uninstalling and re-installing MPLABX. Has anyone else encountered this issue? What else should I try?
It seems that some PIC devices are partially supported by MPLABX (e.g., PIC16F1829). You can recognize this when creating the project: in the dialog where you select what tools you use, if the icon to the left of PICKit2 is yellow, then it's not possible to program the device directly from MPLABX, and the error message is the one you mentioned here. Only the standalone app can be used to program the MCU. If the icon is green (e.g., with PIC16F690), no problem. The workaround is to create a script (or .bat file?) that uploads the code to the PIC.
After having tried a million things, and lost several days, I downloaded Pickit OSs, drivers, etc. etc. I must say I am very tired, bored and frustrated by the very poor quality of Microchip stuff... Even after reinstalling Windows, the MPLAB behavior is not the same, far to be professional, it is even not at the hobbyist level, a shameI lost enough time and patience (and money !), trully plan to consider Atmel or anything else right now.
I am also seeing the same issue with exactly the same setup. I was using MPLAB X v1.80 without issues and decided to go with the latest version v1.95 - then it stopped working and have never got it to work. All ok via the dedicated programming tool though v2.61. I went back to v1.80 and saw the same error! After some fiddling around unplugging the USB cable and trying different ports, resetting the PICKit2 Options and also running the dedicated programmer and getting it to connect to the PICKit2 then closing it then running MPLAB X again I did eventually get it to work!? Once working it seemed to stay working. It's almost like some setting in the registry needs to get set/cleared. It was not clear either which one of my actions made it spring back into life. I also got it working with v1.90 but took ages to get there but once again it remained working once I tickled it in the right places.For just programming you can just point the dedicated programmer at the location the HEX file lives, set the 'Auto import Hex + Write Device' and just build the code in the IDE using the hammer only icon - i.e. don't clean the build first. The new HEX file then gets picked up automatically by the programmer so the result is the same. This of course is no good if you want to debug with the PICKit 2 though :-/If I find out anything else useful I'll post it here.
Just to be clear here, I am using a PIC 16F684 device and for this PICKit2 this has two yellow dots indicating limited support in MPLAB X. However, in both v1.90 AND v1.80 and earlier versions it programs this device from within the MPLAB X IDE every time and I have also done in-circuit debugging without issues. It was only when moving to v1.95 did this problem start to occur. v1.95 does not seem to allow it to work at all but somehow has also made the previous versions flaky at least when trying to get it to work again. Once working though it seems to stay working and works well. Just very annoying! Microchip, please fix ASAP!
Same situation... Win7, MPLABX V1.95, PicKit 2 V2.61...Was informed it is a USB dll problem, should be fixed in soon to be released V2.00. You should be able to go back to V1.85 in the meantime, or upgrade to PicKit 3 or better for immediate and continued support.
Hardness is by definition resistance of material to embossing or localized plastic (permanent) deformation. Consequently, it also means resistance to wear. The hardness of a metallic material depends on its chemical composition and thermo-mechanical treatment. Carbon is the chemical element that has the greatest impact on the hardness of steel, which is also positively affected by chromium, manganese, vanadium and molybdenum. Together with carbon, the latter elements form new, extremely hard compounds called carbides.
There are several methods of measuring hardness that use their own hardness scales. Relative hardness of steel is determined according to these scales by measuring the depth of penetration of an indenter. A conical diamond is most often used and impressed on a material, then the penetration depth at standard force is measured. Different hardness scales employ their own combinations of test forces and test indentations (cone, ball etc.) and are adapted to the type of material being tested. In the cutlery industry, the most often used scale is the Rockwell scale (HRC).
ZDP-189 steel has an interesting chemical composition as it contains as much as 3% of carbon and 20% chromium (and other alloy elements). It is a powdered steel that can reach as high as 70 HRC if correctly heat treated, while in kitchen knives the hardness is usually around 66 and 67 HRC.
The depth of penetration of an indenter is measured by loading a certain force. Either a ball (HRb) or cone (HRc) can be used. It is a quick and simple measurement, especially suitable for cutlery steels.
The Mohs scale measures hardness of minerals and synthetic materials, characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material. On the Mohs scale, talc has a hardness of 1 and a diamond has a hardness of 10 (according to the new scale, 15).
To measure hardness according to the HRC method a special device is used and it consists of three main parts: an anvil, diamond cone and a measuring dial. A sample is placed on the anvil and a minor load is applied. The measuring dial is set to zero and then a major load is applied. The depth of penetration from the zero datum is measured from a dial.
Unfortunately, it is impossible to combine the highest hardness values, strength and toughness, therefore knife manufacturers are trying to strike just the right balance between these properties, especially when finding the sweet spot between the duration of sharpness and brittleness.
56-58 HRC
Professional German kitchen knives with this hardness value maintain good sharpness if regularly and often honed with a steel honing rod. They are easy to sharpen.
58-60 HRC
This hardness is typical of quality pocket knives, such as Spyderco, Cold Steel and Buck, as well as some Japanese kitchen knives like Global. These knives maintain sharpness for a substantially longer time. They are easy to sharpen.
60-64 HRC
Most world-class Japanese knives fall into this hardness span and they remain sharp for an incredibly long time. They require special care and work on a suitable surface to prevent breakage and damage to the blade. Due to their slight brittleness in combination with a thin blade, they are not suitable for any task. They must be handled gently and precisely. They are easy to sharpen.
65-68 HRC
Powdered steels: ZDP-189, HAP-40, R2, Super X etc.
In recent years, technological advancement spurred the creation of new types of steel that reach hardness as high as 64-68 HRC and boast mind-blowing properties. They are a little harder to resharpen. Knives carefully crafted from powdered steel are crme de la crme of kitchen tools.
