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

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 …

2012年8月22日 · AGND according to the stuffy shirt bunch should be connected, though I have had an atmega328p running though all sorts of "tapping the limits" abuse with only one ground connected, in a 85 degree C 85% humidity environmental chamber for over 2000 hours with no performance issues as of last sample.

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. …

2019年4月16日 · Hi All, I want to make Homemade Arduino Using ATMEGA328P-AU. But I am not been able to find the guidance anywhere on the internet. I am Getting Tutorials regarding the ATMEGA328P- PU. Can Anyone Help me With these? If one of you have already made it can you please share your Gerber Files?

2010年5月5日 · Intro For the development of a solar cell curve tracer with the Arduino I needed a DAC. The Arduino processor, the ATmega328 / Atmega168, has ADC inputs but no DAC outputs. Although the internal ADC contains a 10 bit DAC, this DAC can't be used stand alone. Therefore I developed an external 10 bit DAC, which is build with an integrator. For the schematic see …

2019年4月10日 · The battery should be connected to Vin pin but I didnt know which pin is in the ATmega328p so I just connected it before the 5V regulator. Barebone Arduino.PNG 717×531 71.4 KB Drone Schematic.PNG 1189×810 53.5 KB

2019年4月29日 · I have a project which I have coded using arduino ide, and then bootloaded it to a atmega328p chip and uploaded the same to it. It has to be powered by a battery but the time gets reset when I disconnect or the battery is down. I planned to use an external rtc but it would be better if atmega328p supports an internal RTC without resetting.

2021年3月7日 · After doing that, you will find that a new Tools > Processor menu is available, and you can select "ATmega328P (Old Bootloader)" from that menu. After that, the upload should work as always. Please let me know if you have any troubles.

2012年9月14日 · Hi all! I want to run atmega 328p on 3.3v for my project and for doing the same I gathered some information. As far as I understood, I will have to program the extended fuse bits of the 328 so that i can disable brown out detector (BOD), so that I can run the chip on 3.3V and I will have to program the low fuse bits for the clock if I want to use an external clock of 8mhz (8 …
