warning: pointer targets in initialization differ in signedness
You may get the same warning ("pointer targets in passing argument 1 of 'Display' differ in signedness"). This warning is due the flag -Wpointer-sign that, quoting GNU compiler reference, " ...is implied by -Wall and by -pedantic, which can be disabled with -Wno-pointer-sign ". edited Jun 13, 2015 at 22:06.

Pointer targets in passing argument differ in signedness
11. char is signed type. uint8_t is unsigned. So you are passing a pointer to an unsigned type to a function requiring signed. You have several options: 1) Change the function signature to accept uint8_t* instead of char*. 2) Change the type of parameter you are passing to char* instead of uint8_t* (i.e. change data to be char ).
pointer targets in passing argument of xxx differ in signedness
While non-pointer int and unsigned int. From C standard c99 6.3.1.3. When a value with integer type is converted to another integer type other than _Bool, if the value can be represented by the new type, it is unchanged.
tmp.c:4: warning: pointer targets in initialization differ in signedness. Plain char is either signed or unsigned, depending on the system configuration. Both initializations call for warnings, since plain char is a distinct type. from both signed char and unsigned char, but in one of the two cases it.
Warning Options
The ISO type of an integer constant has a different width or signedness from its traditional type. This warning is only issued if the base of the constant is ten. ... -Wpointer-sign Warn for pointer argument passing or assignment with different signedness. This option is only supported for C and Objective-C.
Solved: Warning: pointer targets in passing argument 2 of
Look at the declaration of the HAL_UART_Receive() function. You will see that this argument asks for a pointer to uint8_t and not a pointer to char. It seems that you are new to STM, but also to the C language. Start with a C training will be very profitable.

When to mix ANSI C types and stdint.h types? : r/C_Programming
This happens also when trying to mix int8_t* with char*. Yet, char* is used everywhere in the standard library, and everywhere in libraries using a C API. stdint.h was just an a clunky, unwieldy bolted-on addition to C, which still deals with standard types. For example, to print integer types, you might use format codes "%d", "%ld" and "%lld ...
