This circuit solved a problem encountered in developing a portable device with an ARM Cortex-M0 processor. The power supply consisted of two AA batteries (2 × 1.5 V), and I needed to signal the ...

Two examples help illustrate how you can design a signal-conditioning circuit. For the first example, suppose you need to monitor a DC bus voltage using a microcontroller ... a signal and thus its ...

Because the calibration value is unique to each microcontroller, problems arise for time-sensitive applications if you erase or overwrite the last address. The circuit in Figure 1 ...
