I find that most of programmers do not use the boolean data type. If i know that my data can be 0 or 1, if i use boolean i will save memory but still it is not used much. What are the disadvantages?

#include <stdio.h>
int main()
{
int number=0;
char digit=0;

while(1)
{
printf("Enter the digit\n");
scanf("%c",&digit);

#include <stdio.h>
int main()
{
int number=0;
char digit=0;

while(1)
{
printf("Enter the digit\n");
scanf("%c",&digit);

I am really sorry how that mistake happened. I will try with the changes.

Write a function int convert () that reads a decimal number one character(digit) at a time, terminated by a blank, and returns the value of that number.

Hi,
I need to transmit data over CAN, but i am really struggling to organize the software flow. The below is the prototype function to transmit

Hi,
Need some advice, I need to do a USB write blocker software, I wanted to know how complicated it is? Which programming language to use? I have never done this kind of programming. Please help.

I am referring to a micro controller based embedded C programming. Most of the time the processor i am working with has very limited time, where the number of tasks are more, for example
a. Analog...

i have a function


void SendData(sint32_t data)
{
Transmit();
}


One problem i am seeing is i need to send data of max size of uint32_t and also a function requiring to transmit a data...

Yes I receive data, I had problems receiving for higher values, then I figured one mistake of argument, I defined as uint instead of the signed. I am having difficulty in transmitting new line hence...

I have multiple doubts, hopefully i can get clarified here



int16 datatotransmit[100];

int main()
{
while (index <= 90) /*transmitting 90 elements of datatotransmit array */
{

Why do you think so, any reason?

I am getting really confused now, if i have a signed value for example -634, what will the MSB and LSB of the number?

I want to transmit a variable over UART and also LCD, the UART is a generated function with argument of uint8_t, the data i need to transmit is both signed and unsigned and it is 16 bit. How do i...

I hope, this is what you mean?

void Rms(uint16 rawcount_16)
{
uin32_t l_temp_square_u32=0;
int32_t l_temp_offset_s32=(int32_t)rawcount_16;
l_temp_offset_s32 -= 512;
l_temp_square_u32 =...

Ok one point i forgot to mention is that rawcount can be maximum is 1024.

Ok i understand now it shall be like this


void Rms(uint16 rawcount_u16)
{
uint16_t l_temp_rawcount_u16 = 0;
uint32_t l_temp_square_u32=0;
int32_t l_temp_offset_s32 =0;
l_temp_rawcount_u16 ...

I tried with the following code


void Rms(uint16 rawcount)
{
uint16_t l_temp_rawcount_u16 = 0;
uint32_t l_temp_square_u32 = 0;
int16_t l_temp_offset_s16 = 0;
l_temp_rawcount_u16 =...

I am trying to calculate the RMS value, but i need to offset by 512,
I get the raw value from 0 to 1024, i need subtract 512 from this number and then square the number, but i get warnings


...

I saw the code


typedef signed int SFRAC16;
#define Q15(Float_Value) \
((Float_Value < 0.0) ? (SFRAC16)(32768 * (Float_Value) - 0.5) \
: (SFRAC16)(32767 * (Float_Value) +...

I have seen this type declaration. Can someone explain me this


typedef unsigned int uint16;
typedef uint16 Buf[32][8];
Buf buf1;


I slightly modified the variable names....

I am facing serious problem of understanding and confusion of Motorola and Intel formats. My requirement is I have to transmit 8 bytes of data using CAN communications it is serial communication....
