How can I read two separate bytes each with LSB first?
2 speparate LSB first bytes -> one short int MSB first
e.g. 01001100 11001100 -> 00110010 00110011
short int lsbToMsb(char byte1, char byte2) {
...
return msb;
}

Try this:
char reverseBits(char byte)
{
char reverse_byte = 0;
for (int i = 0; i < 8; i ) {
if ((byte & (1 << i)))
reverse_byte |= 1 << (7 - i);
}
return reverse_byte;
}
short int lsbToMsb(char byte1, char byte2) {
byte1 = reverseBits(byte1);
byte2 = reverseBits(byte2);
short int msb = (byte1 << 8) | byte2;
return msb;
}
int main(){
char byte1 = 76; // 01001100
char byte2 = -52; // 11001100
short int msb = lsbToMsb(byte1, byte2);
printf("%d", msb);
}
Output:
12851 // 00110010 00110011
