With havin so much content and articles do you ever run into any issues of plagorism or copyright violation? My website has a lot of unique content I’ve either written myself or outsourced but it seems a lot of it is popping it up all over the internet without my authorization. Do you know any techniques to help protect against content from being stolen? I’d truly appreciate it.
Hi, we are not sure about that too. But it is fine for us as we like to share.
Hi,
I am having a problem compiling these tutorial projects. I am using MPLAB 8.3 and Hi-Tech Compiler 9.65 (Lite and PRO) but so far have only managed to compile PR2 and PR13. All the rest have the same error message which is related to the lcd.c code. The message is as follows:
Error [712] C:\…….\Project_15\lcd.c; 276. can’t generate code for this expression
Line 276 of the lcd.c file reads as follows:
unsigned int ui_decimal[5] ={ 0 };
Code snippet is as follows:
void lcd_bcd(unsigned char uc_digit, unsigned int ui_number)
{
unsigned int ui_decimal[5] ={ 0 };
//extract 5 single digit from ui_number
ui_decimal[4] = ui_number/10000; // obtain the largest single digit, digit4
ui_decimal[3] = ui_number%10000; // obtain the remainder
ui_decimal[2] = ui_decimal[3]%1000;
ui_decimal[3] = ui_decimal[3]/1000; // obtain the 2nd largest single digit, digit3
ui_decimal[1] = ui_decimal[2]%100;
ui_decimal[2] = ui_decimal[2]/100; // obtain the 3rd largest single digit, digit2
ui_decimal[0] = ui_decimal[1]%10; // obtain the smallest single digit, digit0
ui_decimal[1] = ui_decimal[1]/10; // obtain the 4th largest single digit, digit1
if (uc_digit > 5) uc_digit = 5; // limit to 5 digits only
for( ; uc_digit > 0; uc_digit–)
{
lcd_putchar(ui_decimal[uc_digit - 1] + 0×30);
}
}
There seems to be a problem with unsigned integers in the above code. I contacted Hi-Tech tech support and they said that the “can’t generate code” error message means there is a statement that is too complex for the compiler!
Please could someone at Cytron confirm that these projects have all been successfully compiled and if so what setup (MPLAB and Hi-Tech Compiler) they used?
Many thanks,
Dave Keogh
please give me the hex.file for obstacles avoidance robot,where PIC16F877A interface with DC motor and IR sensor(analog distance sensor)..
Hi Dave Keogh,
Please use the latest compiler. All these source code are compiled with Hi-tech v9.80. Any version newer than 9.80 should work. Thanks.
Hi Nabeel,
Please refer to PR23.
