Identifying a transistor
Hello there,
I have a transistor that I am trying to identify. Unfortunately it is not clear from the markings what exactly it is.
This is what I know about it:
SOT-523 Package
Writing 702, on the side V I I
What could it be? Does anyone know? Can anyone help...
Hmm, too far.
I am in Canada.
Another thing I would look for is the date of manufacture. Some PICs did not exist before certain time. Also on the device you removed it your CPU from, see where the clock inputs are, that will narrow it down. In the end there could be about 10 pics that could...
This is for a commercial project. I just needed to study it a little bit. I looked at the Agilent optical mouse, it uses one cyprus microcontroller. I just do not want to spend too much time learning a new architecture. Time is money. :-) If there is something out there I could learn faster...
vb ieee 754
This is for C:
union FloatToChar
{
double fr; // 4 bytes as a long 32 bits.
unsigned char br[4]; // 4 bytes as 4 chars
};
union FloatToChar y;
Very nifty, luckily VB and the C compiler for the microcontroller use the same format for the 32bit floating point numbers
visual basic convert double ieee binary
This is what I figured out for VB:
Private Declare Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" (pDst As Any, pSrc As Any, ByVal ByteLen As Long)
Private Sub SingleToIEEE754()
Dim bBytes(0 To 3) As Byte
Dim rMyNumber As Single
Dim i As Integer...
ieee 754 vb6
I am trying to send a floating point number from VB to my C program runing on 16f876. In C I converted the IEE754 to a 4byte array, yet the Visual Basic does not have the same functions (UNION) is there some solution to transfer floating point number in byte format that is better...
site:www.edaboard.com frequency counter
These PIC based Frequency Meters do not depend on the speed of the MPU too much. It has mainly to do with the speed of the gate at the input of the counter. So a 20Mhz device will not give you any more than the 4MHz component. Here is one that is...
galblast site
If you follow the links to the geocity site you will fine GalBlast 1.6. I also spoke to the kosto guy in Czech republic and he says that he will have a new batch of the boards ready in about two to three weeks. He want 350Kc which is about $10. Not bad at all. I will let you know...
galblast
I am looking at it too, There is a better version of the circuit board for this at:
**broken link removed**
Does anyone have the isp Synario 2.1 / 2.3 Starter? Latice stoped carying it. :sad:
