Figure 1 shows a simple, stand-alone overvoltage detector. The intent of the circuit is to monitor a voltage, VMONITOR, and set the output, VOUT, high when the monitored voltage exceeds a preset threshold. The minimum allowable threshold for this cir…

The circuit in Figure 1 uses a minimal number of external parts to raise the maximum output current of a 0.5A buck switching-regulator IC to more than 6A. The circuit accommodates input voltages of 15 to 60V and delivers output voltages of 3.3, 5, or…

Many applications require current sources rather than voltage sources. When you need a high-current source, using a linear regulator is inadvisable, because of the high power dissipation in the series resistor. To solve the wasted-power problem, you…

JTAG Finder Figuring out the JTAG Pinouts on a Device is usually the most time-consuming and frustrating process and Finding the pinouts for these ports allows you to access with correct JTAG Devices likeGPG ORT,  and JTAG Finder helps you to get sta…

Memory leakage has been a permanent annoyance for C/C++ programmers. Under MSVC, one useful feature of MFC is report memory leaks at the exit of an application (to the debugger output window, which can be displayed by the integration environment or a…

Hi, My Android Xamarin.Forms application uses a Navigation stack to display various views, I often have a list on a screen (A) that once a cell is clicked I push onto the stack a new screen (B), the user completes some form fields and then clicks a b…

Forms and actions Adding new albums We can now code up the functionality to add new albums. There are two bits to this part: Display a form for user to provide details. Process the form submission and store to database. We will use zend-form to do th…
