Hello,
I have a PCI card and I would like to know whether or not it is working.
Is there an external device I can connect my PCI to, and then using some software I can communicate with my PCI?
Thanks
You cannot change the flashing rate of the LEDs by just connecting the LEDs in series to the main. When you do so, the LEDs will turn ON/OFF 50 or 60 times every second - most probably, you will not see it flashing.
The box you marked in red contains a controller that changes the flashing...
I know that this topic had been discussed many times before throughout this forum, so I will be very specific.
Have anyone managed to establish a GPRS connection using just a mobile phone and AT Commands?
I managed to do it with ADH8066 GSM module, but I'm asking specifically about using...

The single "&" sign before a variable indicates that you try to the "Address Of" the value in the memory, not the value stored in this variable.
For example:
Suppose we have an integer variable...
OK, try the following steps:
1- What kind of GPS are you using? Some GPS modules may have UART signal levels different than their supply voltage. For instance, the GPS EM406A has a 5V supply however, the UART levels are 2.8V so, check the datasheet of your GPS for the UART levels.
2- Check your...
Connect the GPS to the computer directly through MAX232 and see if the GPS is actually working. You may have problems with the power supply of the GPS or you've swapped the TxD and RxD pins.
Maybe you need to re-enable the interrupt from the configuration register.
Or, as FvM said, polling the input pin will do the job especially when no other tasks are done by the controller.
You can also use the compilers' built-in libraries to implement I2C protocol on GPIO pins as ckshivaram said. Compilers like MikroC has built-in libraries for I2C, SPI, UART... etc.
Another solution is to multiplex the address lines, but this will require extra hardware.
