For the Linux, Mac, and source packages, readme.txt is in the share/doc/gcc-arm-none-eabi folder. For Windows packages, readme.txt is in the top-level folder. Recent releases are available below. Older releases can be downloaded from Launchpad (see also timeline of older releases on Launchpad ). Actually we don't use arm-linux-gnueabi and arm-linux-gnueabihf on Windows host to develop linux kernel and drivers, but we use them to develop Linux applications on Windows host, mainly our customers use them, because customers are not familiar with the manner of Linux development, customers focus on their domain such as industry.

From Richard's post:'You need to use the proper molecular weights for measurements. For chlorine, it is measured in ppm Cl2 that has a molecular weight of 70.906 g/mole while for CYA it's in ppm CYA itself which has a molecular weight of 129.075 g/mole.

You do not use the molecular weights of Trichlor or Dichlor themselves since the rule is comparing ppm FC vs. Ppm CYA.Trichlor has 3 chlorine attached to a CYA core (s-triazine ring) and they all can produce hypochlorous acid in water. So, 1 mole of trichlor produces 3 moles of chlorine and 1 mole of CYA.

For Cal-Hypo with a molecular weight of 142.98366 g/mole and producing 2 chlorine for every mole of calcium hypochlorite (remember that it is Ca(OCl)2), the% Available Chlorine is 2.70.906/142.98366 = 99.181% so is essentially the same as it's purity so that 65% Cal-Hypo is around 65% Available Chlorine (64.468%, actually), etc. The effect any hypochlorite-based chlorine has on pH, and therefore on water balance in general, is the main reason why spa treatments with dichlor (the chlorinated isocyanurate, sodium dichloro-s-triazinetrione) sell much better. Dichlor is almost pH neutral, being about pH 6.7.

So the ratio of ppm CYA to ppm FC is 129.075/(3.70.906) = 0.60679. Dichlor has 2 chlorine attached to a CYA core so 1 mole of dichlor produces 2 moles of chlorine and 1 mole of CYA. So the ratio of ppm CYA to ppm FC is 129.075/(2.70.906) = 0.91018.What's really confusing is when one starts talking about '% Available Chlorine' which is a weight%, but 100% is defined relative to chlorine gas and only one of the two chlorine in chlorine gas produces hypochlorous acid while the other produces chloride (from hydrochloric acid when chlorine gas combines with water). So every chlorine atom that produces hypochlorous acid is counted twice in terms of weight%. Trichlor has a molecular weight of 232.4103 g/mole so the% Available Chlorine is 3.70.906/232.4103 = 91.527% even though the weight% of atomic chlorine in Trichlor is half that percentage.

Trichlor is around 99% pure product which is why the% Available Chlorine is usually quoted as 99%.91.527% = 90.6% or thereabouts.Similarly, Dichlor dihydrate has a molecular weight of 255.97766 g/mole so the% Available Chlorine is 2.70.906/255.97766 = 55.400%. For Cal-Hypo with a molecular weight of 142.98366 g/mole and producing 2 chlorine for every mole of calcium hypochlorite (remember that it is Ca(OCl)2), the% Available Chlorine is 2.70.906/142.98366 = 99.181% so is essentially the same as it's purity so that 65% Cal-Hypo is around 65% Available Chlorine (64.468%, actually), etc.

Sodium Hypochlorite has a molecular weight of 74.4422 g/mole and each mole produces one mole of chlorine so the% Available Chlorine is 70.9 = 95.250% so is close to the weight% (purity) of product. This is why 6% bleach (which means 6% by weight of sodium hypochlorite) is 6%.95.25% = 5.715% Available Chlorine.Yet another confusing number that is used is Trade% which is the Volume% of Available Chlorine (as opposed to Weight%). This factors in the density of the product where the Trade% is the (weight)% Available Chlorine times the density (specific gravity). Since 6% bleach has a density of around 1.08, it's Trade% is 5.715%.1.08 = 6.172%.

Graphtec ce5000 40 crp drivers for mac. When one wants to easily calculate the FC rise of adding 1 gallon of chlorine to 10,000 gallons of water, it's the Trade% that is most easily used since the rise is 6.172 ppm FC.Richard'PS - I miss this guy.

The key difference between trichlor and dichlor is that the Trichlor (or trichloro-s-triazinetrione) is a dry solid compound having the highest possible content (around 90%) whereas, the Dichlor (or dichloro-s-triazinetrione) is available as its dihydrate form or the form.The chlorine content of the dihydrate form of the dichlor is around 56% while the chlorine content in anhydrous form is about 62%. The main use of both these compounds is mainly in cleaning swimming pool water, spa water and hot tubs.CONTENTS1.2.3.4.5. What is Trichlor?Trichlor is the short name for trichloro-s-triazinetrione. Trichloroisocyanuric acid is another name.

It is a solid dry compound with the highest possible chlorine content. It contains about 90% chlorine. People use these compounds to clean water in swimming pools, spa, and hot tubs. Figure 1: Chemical Structure of TrichlorTrichlor adds cyanuric acid to water. This acid is useful in stabilizing the free chlorine in the water.

Since it is a solid containing concentrated chlorine, it provides the residual level of chlorine required to kill pathogenic organisms in water. Moreover, it destroys the contaminants (such as those found in sweat, urine, etc.) found in water. Therefore, it acts as a sanitizer.Trichlor is commercially available in granular and tablet form. Furthermore, this compound is completely soluble in water, and it does not contain any calcium. It is suitable for hard water cleaning as well. The pH and the total alkalinity of water considerably reduce when we add trichlor to the water.

When it dissolves in water, it produces hypochlorous acid and hypochlorite ion (also known as free available chlorine). The hypochlorous acid acts as a biocide. What is Dichlor?Dichlor is the short name for dichloro-s-triazinetrione. This compound is available in two forms as dihyrate form or anhydrous form. The dihydrate form contains around 56% chlorine while the anhydrous form contains around 62% chlorine. Therefore, it is useful in treating water in swimming pools, spa, and hot tubs.Application of this compound to water increases of residual chlorine level required to kill pathogenic organisms in water.

It also acts as an algaecide as well as a sanitizer.Unlike the application of trichlor, the application of dichlor slightly reduces the pH and total alkalinity. This compound is completely water soluble. It also produces hypochlorous acid and hypochlorite ion when dissolved in water. Dichlor is typically sold in granular form. However, it depends on the its form: dihydrate form or anhydrous form.
