i compiled your code, it gave no errors. I tried to run it without a webcam, i received the same error as you did.
There are two things you can do to solve this problem
1. Get a new webcam and try the code
2. Try modifying the number in this part of the code capture = cvCaptureFromCAM(0);
try...
I was able to search for a code that can transmit what i want, but the problem is when i tested it, it only transmits 1 decimal place, i would like it to transmit two decimal places, how can i do it?
This is my
ad_value = Adc_Read(0);
Vin = adc_value*(5.00000/1023.00000)...
sorry about that, my ADC value will be integer, and i want it to be converted to a string, otherwise, my receiving node will display a character corresponding to the hex equivalent of the ADC integer. i see that the code you gave me is for UART_write, but i am currently using USART_write(), i am...
i'm having trouble converting the ADC value to character string, how do i convert it? i used InttoStr(myvalue ,stringvalue ) still i get the wrong data
how do i send my data from ADC to Usart? This is my code, and i am not able to send the data that i need. I am not that good in programming microcontrollers. i am currently using PIC16F877A and MikroC
void main(){
ADCON1 = 0x00; // 8-bit converter, 0000 Ports E and A are analog inputs...
Thank you all for your help, the problem is now solved :) the issue is not about the hardware and the software, it's in my OS, we reformatted our PC an installed again my devices :)
i have done all the corrections in the schematic, still it goes wrong :( . can the issue of this one is that the Driver is installed incorrectly? or i am using Ubuntu OS?
I have configured the Xbee Series 2s correctly. Also, all the tests were done. My max232 is supplied with 5 volts, my xbee is supplied with 3.3 volts. and i noticed that the capacitor(in red circle) is the one Sir Alex was talking about
i followed this schematic from sodoityourself.com. my power source for my schematic is a 9 volt 10W AC to DC adapter, i used 5 volt regulator for MAX232 power supply and 3.3v regulator for Xbee power supply

I am currently using Xbee Series 2. My code above is supposed to be transmitting '1'.
for the testing:
I ran the code above in a...
