euclidean angle to a quaternary number
Define pitch, yaw, and roll to rotate radians around the X axis, Y axis, and Z axis respectively.
Float P = pitch * piover180/2.0;
Float y = yaw * piover180/2.0;
Float r = roll * piover180/2.0;
Float sinp = sin (P );
Float Siny = sin (y );
Float SINR = sin (R );
Float COSP = cos (P );
Float cosy = cos (y );
Float cosr = cos (R );
This-> X = SINR * COSP * cosy-cosr * sinp * Siny;
This-> Y = cosr * sinp * cosy + SINR * COSP * Siny;
This-> Z = cosr * COSP *
the empty C column out, then I can use Sheet.cell this method, by passing in the cell number and add null value to create a new column.
Alen = Len (ColA) for I in range (1, Alen + 1): Sheet.cell (' c%s '% (i)). Value = None
Note: Excel cell naming is starting from 1 ~
The above code is also shown, to get the value of the cell is Cell.value (can be left or right), its type can be a string, floating-point

Pre-compilation is generally used to prevent repeated inclusion and compilation of header files. The pre-compilation command indicates the operations performed by the compiler before the program is officially compiled, and can be placed anywhere in the program. This article briefly introduces the pre-compiled commands in C.

After the above socke is created, we will naturally think of the following work, that is, bind.
5.6 bind Analysis of l2cap
According to international practice, after the socket is built, bind is bound, haha ~~
if (l2cap_bind(sock, opts->src, server ? opts->psm : 0, opts->cid, err)
This function is as follows:
Static int l2cap_bind (int sock, const bdaddr_t * src, uint16_t psm, uint16_t cid, GError ** err) {struct sockaddr_l2 addr; memse
