# modbus\_set\_bits\_from\_bytes(3)

set many bits from an array of bytes

## NAME

modbus\_set\_bits\_from\_bytes - set many bits from an array of bytes

## SYNOPSIS

**void modbus\_set\_bits\_from\_bytes(uint8\_t \****dest***, int** *index***, unsigned int** *nb\_bits***, const uint8\_t \****tab\_byte***);**

## DESCRIPTION

The **modbus\_set\_bits\_from\_bytes** function shall set bits by reading an array of bytes. All the bits of the bytes read from the first position of the array *tab\_byte* are written as bits in the *dest* array starting at position *index*.

## RETURN VALUE

There is no return values.
