Because there is a high probability that data sent by the transmitter will be corrupt or only partially received, it s important to have some way to check the validity of the message The La Crosse transmitter includes a checksum in the message so the receiver can make sure it arrived correctly The checksum calculation function doesn t take any arguments because when invoked it operates on global variables that have already been set, and all it needs to return is a pass/fail response value.

Internally, the function uses the variable dataPos to indicate the position within the data array that it will examine, and it accumulates the result of examining each byte into the checksum variable byte PacketAndChecksum_OK_WS2355(void) { byte dataPos; byte checksum; It skips across the first four bytes, though, because they re the timestamp and aren t included in the checksum calculation, which only applies to the first 48 bites (12 nibbles) of the message payload checksum = 0; for( dataPos = 4; dataPos < 10; dataPos++ ) { checksum += (bICP_WSR_PacketData[bICP_WSR_PacketOutputPointer][dataPos] >> 4); checksum += (bICP_WSR_PacketData[bICP_WSR_PacketOutputPointer][dataPos] & 0x0F); } The accumulated value then has a bitwise AND operator applied against the value 0x0F checksum &= 0x0F; The result is then compared to the checksum value sent in the transmission and the function immediately exits with a false value if it fails the test.

How to add a watermark to a PDF file? - Stack Overflow

using these languages, the default for the SetLastError field is false. When a DllImport attribute is used in VB.NET, the default for this field is also false. However, VB.NET also supports the older style Declare statement to declare unmanaged functions. If you use the Declare statement, the default behavior is to set the last error code for you. This provides you the same effect as if you coded a DllImport attribute with SetLastError set to true. When using this older Visual Basic syntax, you can still reference the Err.LastDllError property to obtain the error code.

if( checksum != (bICP_WSR_PacketData[bICP_WSR_PacketOutputPointer][10] >> 4) ) { return( false ); } The next thing that is checked is the first non-timestamp byte of the message payload, which must always be 0x09, or binary 00001001 This appears to be a general identifier for this type of weather station and might be different for other models, but for our purposes we can simply do a direct comparison and ignore messages that don t have this byte set correctly if( bICP_WSR_PacketData[bICP_WSR_PacketOutputPointer][4] != 0x09 ) { return( false ); } If those checks all passed then the message is probably okay, so the function returns true and bails out return( true ); } The Init_RF_Interpreters function is called once during setup() to make sure everything is ready to go, and makes extensive use of macros that were defined in the header file.

It s better to estimate as accurately as you can and ask for slack time when you need it..

A number of Win32 functions require callbacks. How do you handle callbacks from unmanaged functions

This approach can dramatically improve the readability of your code at a high, abstract level because you can read a line such as WSR_RESET() and know that it resets the weather station receiver state machine On the other hand it can make the details of your code more opaque, because seeing a call to WSR_RESET() doesn t help you understand how that macro works Use of macros to simplify your code is a balancing act between conciseness and opacity In this project, WSR_RESET() simply resets the state machine value and the packet bit position pointer..

Callbacks are the general mechanism that permits a called function to invoke another function specified by the caller. This technique is typically used where the called function must return an unknown amount of repeating data to the caller.

When you power up your Arduino and speech synthesizer shield it will immediately say "ready," even if you haven't sent any values to the SpeakJet yet. That's just the SpeakJet's internal self-test indicating that it has finished and is ready to receive commands.

Note Callbacks are discussed in this chapter since they are a technique used by a number of Win32
