whether we want to right a character or a string, both can be done by specifying it in these square brackets. Let us take some cases: char arr[15]; 1. scanf(“%[a-z]c”,&arr); 2. scanf(“%[a-z]s”,&arr); Accord
Another good option is to output debug information over the serial port (UART). We can call the STM32 HAL functions (e.g. HAL_UART_Transmit), but sometimes it’s easier to use the standard C library functions printf, scanf, and so on. To do that, we need to re-write the ...
How to Use Assert in C Programming? The Assert macro is used to check and validate conditions during runtime and is especially useful for programming debugging. Before we begin, we must include assert.h in the header file, which will call and declare the method assert(int expression), for ...

C++ language does not provide a sleep function of its own. However, the operating system’s specific files likeunistd.hfor Linux andWindows.hfor Windows provide this functionality. When we use the Linux or UNIX operating system, we need to include “unistd.h” header file in our program to...
I am using the USB-Serial Bridge (CY7C65211) that is included with the prototyping kit, and just wiring P0.4 and P0.5 to the Serial Bridge. But I've never heard that it's necessary to use the SCB component, in other projects I used the UART v2.5 component, and it worked just fin...

For a new project I need to send and read data, ASCII char numbers, from the serial port to the PSoC. I've been trying to send and receive strings from Serial Port to the PSoC 4, sending strings is easy with UART_PutString(); , but I cant read them yet. I was looking in the ...
The character class is supposed to contain all characters we wish to read into the string. If a character not in the character class is read, the read operation will terminate. In this case, we use [^\n]. The ^ at the first position has a special meaning, and is used to negate the...
