One set of drivers is for the actual LCD display screen, and the other set of drivers is for the touchscreen sensors. There are two types of drivers we need to be concerned with here.
CX PROGRAMMER 9.42 SERIAL INSTALL
TimeAction(pair.What we need to do to get the LCD working is install and configure the FBTFT drivers created by notro. TimeAction(pair.Key + " calculation", 500, () =>Ĭonsole.WriteLine(" = Many string test") List manyString = new List(MANY_STRING_COUNT) Īlgorithms = BitConv Īlgorithms = StringBuilderTest Īlgorithms = ByteArrayToHexString Ĭonsole.WriteLine(" = Long string test") Var source = GetRandomBytes(LONG_STRING_LENGTH)
(Same byte count as first test but in different arrays) With: int MANY_STRING_COUNT = 1000 int MANY_STRING_LENGTH = 1024
LinqAgg calculation Time Elapsed 9230 ms.LinqJoin calculation Time Elapsed 19433 ms.LinqConcat calculation Time Elapsed 21512 ms.StringBuilder calculation Time Elapsed 8289 ms.BitConvertReplace calculation Time Elapsed 3431 ms.With: LONG_STRING_LENGTH = 100 * 1024, Similar results ToHex calculation Time Elapsed 19,167 ms (fastest).LinqAgg calculation Time Elapsed 93,087 ms (StringBuilder with reallocating).LinqJoin calculation Time Elapsed 181,142 ms.LinqConcat calculation Time Elapsed 182,094 ms.StringBuilder calculation Time Elapsed 75,723 ms (StringBuilder no reallocate).BitConvertRep calculation Time Elapsed 27,202 ms (fastest built in/simple).ToHexFromTable = Linked in answer by Nathan Moinvaziri, for me this is near the same speed as the above 2 but requires an array of 256 strings to always exist.ByteArrayToHexString = Answer by Nathan Moinvaziri, approx same speed as the ToHex above, and is probably easier to read (I'd recommend for speed, where you can't use Convert.ToHexString).ToHex = Answer by Kurt, sets chars in an array, using byte values to get hex.LinqAgg = Answer by Matthew Whited, IEnumerable.Aggregate with StringBuilder.LinqJoin = Answer by mloskot, string.Join of Linq built array.LinqConcat = Answer by Michael Buen, string.Concat of Linq built array.StringBuilder = Answer by Quintin Robinson, foreach char StringBuilder.Append.BitConvertRep = Answer by Guffa, BitConverter and String.Replace (I'd recommend for most cases, where you can't use Convert.ToHexString).
CX PROGRAMMER 9.42 SERIAL CODE
Took each bit of code from an answer here:.Probably due to expanding the StringBuilder on the longer strings, so setting the initial size should negate this difference. I also found it interesting that string.Concat and string.Join are much slower than StringBuilder implementations for long strings, but similar for shorter arrays. But the speed can be improved with algorithms like Nathan Moinvaziri's ByteArrayToHexString or Kurt's ToHex. The result is that BitConverter+String.Replace seems to be faster than most other simple ways. I thought I would attempt to compare the speed of each of the methods listed here for the hell of it.
The rest of this is from before Apr 10, 2012: In my opinion it clearly wins in: readability, performance, safety You'd be foolish to use anything other than Convert.ToHexString. Thanks to benchmark comparison we can see that Convert.ToHexString is by far the clear winner today
