microprocessor

Hello ! I've been learning more about microcontrollers and microprocessor with 16 and 32 bits. So far I've been using MCS-51 the 8 bit microcontroller and I couldn't understand something when I was learning 32 bit STM32. I would like to also confirm if I am right about some facts : - is it...

Hi, I am still relatively new to microprocessor circuits. Please tell me how I can reduce or eliminate the noise introduced into the circuit below? I have a half-decent power supply with a stable output voltage(input about 12 volts, output about 5 volts): But there is noise in the...

Hi everyone!, im currently a student, i know about electrical circuits, basic electronics, digital circuits, basic digital design, microcontrollers, programming and other things, im a biomedical engineer and currently im working as service engineer (giving maintenance to medical equipment) but...

Hi Everyone! I would like your advice on which microprocessor I should use to turn on an RGB LED (basically one color at a time) based on the input value (voltage)? Note: input value range will change in decimals. Thank you.

Hi, I am ok on connecting one 8255 i/o chip to an 8085 mpu with an 74138 3 to 8 decoder chip but I am fuzzy on how to connect multiple 8255s? Can somebody please enlighten me, thanks?

I am an absolute beginner in Embedded Systems and I had an idea to test the Allwinner A83T processor with an bare bones board test and so I completed the design yesterday. But before I get it made by JLCPCB (because of $8 4 layer fabrication), I need somebody to tell me if this will boot and...

Part: https://www.digikey.com/en/products/detail/atmel/ATSAMD21E18A-AU/13480283 Mainly trying to find a replacement for this particular I2C however I am hitting a huge roadblock that I suspect has a lot to do with the current "Chip shortage" that is often discussed. Unfortunately at the heart...
