I'm trying to read an audio signal from an Android phone as a serial input to an MSP430G2553, adapting this design to use the MSP430's onboard comparator module instead of an LM324. The Android code ...
I am working on a redesign and there is a negative bias generator on the ADC in the circuit. (not the circuit below) I am pretty sure that the small negative voltage instead of ground is there to ...
I am working on a design that requires Two Chips - Energy measuring chip (for analogue measurement) and a MCU (for connecting to a communication peripherals, and connected to a PC.) Both Chips is to ...
I have seen this picture in a number of the Atmel datasheets. This one is from the ATTiny48/88 datasheet. Can someone explain in some detail how to properly implement this on a 2-layer board? I ...
I am considering using a chip, but the datasheet is confusing me as it has several distinct power pins. It has: PLL_VDD PLL_GND AVDD AGND DVDD DGND DVDD_IO DGND_IO This is the chip. How do I ...
