To send data back and forth over The Things Network you'll need to use bytes. It is assigned 1 as its primary bus interface number, 3 as its secondary bus interface number and 0xFF as its subordinate bus number. To make sure all the GPIOB input ports are on known state (all ports high), we activate the MCP23S17 pull-up resistors by assigning 0xFF to the GPPUB register. Next, we color key the image with SDL_SetColorKey before creating a texture from it. CUDA C extends C by allowing the programmer to define C functions, called kernels, that, when called, are executed N times in parallel by N different CUDA threads, as opposed to only once like regular C functions. And these were needed, so the new language could perform “better” at some key benchmark used to once again prove that poor “real world” problems in assembly, C are faster than in new language X. This only works due to the specific implementation of the test cases. (0xFF is the. The simpler example that used the constant, was to show that the conversion from a byte (like the constant 255) was not correctly converting to its hex character equivalent ('0xFF'). 0xFF is one of the ways of showing that a number is in hexadecimal, base 16. If you liked this article and would like to download code (C++ and Python) and example images used in this post, please subscribe to our newsletter. Writing data is quite easy. Counter/timer hardware is a crucial component of most embedded systems. Similar to other ports, a logic one (1) in the TRISC register configures the appropriate portC pin as an input. 1 0x1 0001. Does not crash or cause any errors in Perl 5. In short, & 0xFF is used to make sure you always get the last 8 bits. 6-602-ge9d2bd8.
