Atmega328 vs Atmega328p....what are the differences?
2011年5月1日 · title says it all, what are the differences? i am thinking there would be an issue burning a bootloader to the 328 since it is probably expecting the 328p, and is the 328 newer or older than the 328p? everything i have has a 328p in it but the 328 is $1 cheaper and that adds up quick in volume, so please let me know the difference. bob
ATmega328p + ESP8266 WIFI tutorial - Arduino Forum
2022年1月7日 · Hi, So I had quite some trouble getting my board to work as most things are not straightforward. Therefore, I am writing this short tutorial with everything I learned so people do not have to rediscover everything on their own. This guide is specifically for the UNO R3 + ATmeg328p + ESP8266 WIFI (4Mb) USB - TTL. This thing still feels like a black box to me, so …
Which chip is this: "ATmega328P U"? [SOLVED] - Arduino Forum
2018年8月21日 · On my UNO the chip is labeled "ATmega328P-PU", and I ordered some of those for stand alone projects. The ones I got are labeled "ATmega328P U", and if I put one of them into the UNO, they appear to be perfectly interchangeable. However, I want to change the bootloader to run on the internal 8MHz clock but it seems like I cannot burn the bootloader to the new …
Extend ATMEGA328P-AU pins - Microcontrollers - Arduino Forum
2023年4月5日 · Hi Guys, I'm looking a way extend the pin's ATMEGA328P-AU chip without using any other component like shift register (this will be my last solution). My project will use the 23 IO pins available (in green) and i need at least 3 extra IO pins, So I have ADC7, AREF, ADC6, AVCC. Questions: ADC7 and ADC6: I know we can use analog pin as output pin, so OK. …
Ch-1 Introduction to ATmega328P Microcontroller - Arduino Forum
2020年12月21日 · 1.1 What is an ATmega328P Microcontroller? It is this 28-pin semiconductor chip of Fig-1.1. The full name is “Micro Controlling Unit”, the short name is “Microcontroller”, and the abbreviated name is “MCU”. The MCU can process only 8-bit data at a time. (a) Pictorial view of ATmega328P MCU (b) Pin/signal diagram of ATmega328P MCU Figure-1.1: Pictorial view, …
16MHz Crystal selection for ATMega328P - Arduino Forum
2019年9月3日 · Hi everyone, I am trying to move my next Arduino project to my own designed printed circuit board using the ATMega328P. I however got a bit overwhelmed when looking for a 16MHz crystal for the ATMega328P. I am still quite new to electronics, but what I know is that Crystals allow the processor IC to count and define a cycle. However when looking on the …
What is AVCC for on the ATMEGA328? - Arduino Forum
2011年7月17日 · Hi All I am wondering if anyone can explain in plain english what the AVCC pin is for on the ATMEGA328? Looking at the schematic for the Arduino I see it is connected to 5+ via a component L1 marked at 100uH. What is this component (an inductor/choke?) and what is it's purpose? For my purposes of creating a perfboard arduino would I lose anything by simply …
CAN bus with Atmega328P - Project Guidance - Arduino Forum
2014年10月22日 · THe sparkfun board is using the MCP2515 CAN controller. I only want to use a CAN transceiver in order to communicate between 4-5 Atmega328P. This is why I was asking for a chip similar to SN65HVD104 or 230. They can do the job pretty well but I wasnt sure why some have some split line and some other don't have any split line.
Difference between ATMega 328P and ATMega2560V-8U
2023年5月15日 · Hi I am currently working with a sensor where it originally uses the ATMega328P. However, I want to switch to the ATMega2560 but am confused at the pin configuration. I have looked at the schematic for the two and certain pins are clear cut and I can transfer/convert them over from 328P to the 2560V easily. However there are many others that …
Help choosing between ESP8266 and AtMega328p - Arduino Forum
2021年9月28日 · Hi, I am currently working on a project which doesn't have any size (small to medium) or performance preferences. I have to choose between one of those ESP8266 all-in-one modules (the ones with the integrated antenna) or a classic AtMega328p. My project doesn't use wifi, but here's the problem: Atmegas seem really impossible to find (even on ebay they tend …
