d3ac9c1696 coils: ability to configure number of supported coils 
No change to current default behaviour of allocating 2000 coils.
However memory usage can be reduced by defining NMBS_MAX_COILS.

8dafc721fa Add registers count checking for file_read and file_write operations 
MODBUS Application Protocol Specification does not require it explicitly
but without this checking PDU of a request or response may exceed 253 bytes.

f2b6ddda71 Fix to data pointer type of raw_pdu functions 2022-12-28 14:10:06 +01:00
Antonio Aguilera
fa02201710 Fix Wswitch-enum and Wcast-qual compiler warnings 
The function nmbs_strerror does not handle the error code
NMBS_ERROR_INVALID_UNIT_ID inside the switch statement, which triggers
the GCC/Clang Wswitch-enum warning. Adding a new case inside the switch
statement solves this warning.

There is a cast from a const void pointer to an uint8_t pointer inside
the function nmbs_send_raw_pdu, which triggers the GCC/Clang Wcast-qual
warning. Adding the missing const qualifier solves this warning.

70c75cb2db Convert get_ and put_ to functions 
This shaves off about 1 kB of flash usage from my client application.
It is also more type safe, which is nice.
