When I run this code it gives me an error, I am still a beginner so I don't know how to fix it.
This is what I have written so far
Giving a look in your code, you missed to place some semicolons (;) at the end of some instructions, to be more specific you miss them in lines:
5
32
34
37
40
In line 9, you have to type "Serial.begin(9600);" instead "serial.begin(9600);"
On the last else, you forgot to enclose the instructions between "{}" and placing the '}' to close the void loop.
You are making reference to a routine named getVoltage, but I don't see it
Another issue that I can see is that you have to write with uppercase words like: OUTPUT, INPUT, HIGH and LOW
Please share more details once you be able to fix this observations

I'm experiencing a perculiar issue when using sprintf.
I need a char array to look like this: g;cmd;arg;e;, where arg gets leading zeros so it is always 3 chars long, and cmd gets leading zeros so it's always 15 chars long.
As an example, if cmd = 20 and arg = 3749, I need a char array looking like this: g;020;000000000003749;e;.
Both arg and cmd are integers.
I initially accomplished this in pretty inefficient way, but I changed it to something much simpler using sprintf because I needed my code to be faster. Both my initial code and my change can be found on github.
My current implementation looks like this:
#define cmdMsgLength 3
#define argMsgLength 15
#define totalFormatedMsgLength (2+cmdMsgLength+1+argMsgLength+3)
#define msgFormater "g;%03d;%015d;e;"
char msgToSendFormated[totalFormatedMsgLength];
void sendMsg(int _cmd, int _arg) {
sprintf(msgToSendFormated, msgFormater, _cmd, _arg);
Serial.print(msgToSendFormated);
}
This seemed to work well, until my uC also had to control 4 ESC's. I honestly can't find any relation between the two, but it seems like this implementation leads to problems with the ESC's, where of course timing is quite important. The ESC's are being programmed correctly, but when using the Arduino function servo.writeMicroseconds to actuate them, they seem to act randomly. After quite a lot of tests, only this change to my code seems to be causing the issue. As this piece code is so simple and the old code (check the github link) also used Serial.print, I assume sprintf is the culprit.
Is sprintf known to cause these sort of timing-issues? Could it be anything else?
As JVApen pointed out, sprintf always writes a null terminator. As msgToSendFormated was not long enough for that, I'd get an overflow. Setting char msgToSendFormated[totalFormatedMsgLength + 1]; fixed the problem.
eCHFao<- -0.141081
#eCHFa1<-0
eCHFb1<- 0.985833
eCHFg1<- 0.199665
meanCHF<- mean(XtCHF)
eVarCHF<- (array,3421)
eVarCHF[1]<- var(XtCHF)
abco<- c(meanCHF, XtCHF1)
for (i in 2:3421) {eVarCHF[i]<- exp(eCHFao + (eCHFb1*log(sqrt(eVarCHF[i-1]))}
this code can't run because of an unexpected closing bracket, I am not sure why the bracket is unexpected or what I am missing?
May be a language problem since the thing that is unexpected is a curly-brace and what is missing are two closing parens (aka "brackets" in some parts of the English-speaking world):
exp(eCHFao + (eCHFb1*log(sqrt(eVarCHF[i-1]))
1 2 3 4 43 # need more parens
The language terms referring to ('s, and {'s is a bit scattered around the world. You should have posted the full error message that started out:
Error: unexpected '}'
... so it didn't actually say "bracket".
In my code, I found one qDebug()<<s; didn't output the content given to it. It's very strange, so I output s.length(). It says 135254, so I'm wondering whether there is a limitation of length which is shorter than 135254? I have read the source header and do not find the result.
i noticed something similar...
This might narrow it down a bit (using Qt 5.5.1 with Windows mingw):
45000 character trace did not show up in qDebug.
10000 character trace did show up in qDebug.
I was able to qDebug my 45000 characters as 5 separate qDebug calls, each was something like this:
qDebug()<<foo.mid(20000, 10000);
then piece them together in a text editor.
it may have been a little nicer to use qDebug's noQuotes feature too, but i don't need to run my script again today so I'm not prettying it up right now.
Good day. The programs function is to take an equipment number (or none), display that number with a description (or all) in alv, and then run IE03 should the user double click on
Program worked fine in client 110, but in 150 a runtime error happens. This morning I tried to make a new program with a shorter name (only lead I had), activated it (window popped up asking me to activate the previous version as well). That didn't work and now the original doesn't work in either.
The program "SAPLSKBH" is terminating because program line is too long, being 78 chars wide which is too much for the internal table "\FUNCTION=K_KKB_FIELDCAT_MERGE\DATA=L_ABAP_SOURCE[]"
It sounds like you are using REUSE_ALV_GRID_DISPLAY for output, is that correct?
Check you source code; somewhere you have a line that is more than 78 characters. The function K_KKB_FIELDCAT_MERGE takes the source code of your program to produce a structure that corresponds to the table/structure you give it. (In the old days, there was a limit of 78 characters width for a line of ABAP code, and this is an old function module).
You can alternatively build a field catalog yourself in code, rather than use this function.
I am using Windows 7 and have a 64 bit and a 32 bit version of my program. The 32 bit version works perfectly fine, however, I am having issues with the 64 bit version at runtime. I have a list view item created and am filling the columns with my information. All of them are printing, but one is not printing correctly. This is what it is printing (I apologize for the lack of a picture but as a new member I am unable to post pictures):
Truck
ÍÍÍÍHRZ141
ÍÍÍÍHRZ152
It seems to be placing 4 null characters before the information I actually want it to display. Upon further examination, it appears as though the addressing is incorrect. Here is a section of my code where the error is occurring:
Audit * audit = (Audit *)plvdi->item.lParam;
switch(plvdi->item.iSubItem)
{
case 0:
{
plvdi->item.pszText = audit->Truck;
while(plvdi->item.pszText[0] != 'H')
{
plvdi->item.pszText++;
}
}
return true;
This is a temporary fix due to the fact that all of my truck names start with the character H. plvdi->item.psz text is the text display of the list view item, and audit->Truck is a char[]. It should be as simple as:
sprintf(plvdi->item.pszText, audit->Truck);
but that doesn't seem to work. It leaves me with the same error. When run, the address plvdi->item.pszText is 4 bytes less than the address of audit->Truck, after the assignment statement (breakpoint on the while statement), which I believe is causing the 4 null characters. I am just unsure as to how to resolve this problem without a work around such as the one I posted, why this is happening, and why only in the 64 bit solution. Thank you in advance for any help on this matter.
EDIT: From other similar problems I have found within my program, it seems to have something to do with pointers. Everything in my Audit class that came after a selections vector was having problems and appeared to be off by 4 bytes. In another class, I found that everything coming after a pointer to an Audit failed and I also had some issues with strings (which are technically pointers to char arrays). When I moved the elements with pointers to the end of the class in the header file, everything seemed to work fine again. Any idea if strings, vectors, or other similar structures have pointers that are dependent upon 32 or 64 bit systems?
On 64 bit windows platform, sizeof of a pointer is 8 bytes, while is 4 on a 32 bit configuration. Check your code to avoid the 4 bytes size assumption.
