if you connect the programmer on chip direct on pcb with the same way like yours is there problem ? or you must desolder the ic and follow the process that you show us
Hi, nice project, well done!. Hm seems YT deleted my previous comment..... I woudl iket to add two leds, green, when price increasing green turns on, when decreasing red turns on. Is there any workaround to do this? Also, a wifi management would be nice, so if you want to chnage the wifi data, you wont have to rebuild the whole stuff..
If i were to recreate your schematic with 6 stages, each using 1 capacitor of the same statistics as the ones you used, what would the results look like?
I have made a a PCB using this chip and for reset i have already put a switch between ground and 10K resistor with 5V supply so do i need to press it while uploading
Nice video. Thanks. I have a spl scenario. On my usb asp the main chip is damaged and i gavevspare atmega8a . I can solder it . But i wascunable to load the ubadp firmware into it wuthbusb access . Ppeadecsuggestva practicabe way. Thanks Regards Sarma vu3zmv
Thank you, this worked very well and the newest version of the usbASP driver works great too. This was the only video I watched and yet it was the only one I needed. Thank you again, this shit was epic.
Beautiful explanation. Thank you sir for the great tutorial. It worked the first time. It's fantastic. I didn't know what to do until I found your video. I have an Atmega 4809, but it's actually the same. Keep going.
Beyond loading sketches, can this UPDI Programmer be used to set fuses and Lock bits? I have a need to lock an Arduino Nano Every but don't have access via AVRDUDESS.
Thanks for a clear explanation of this. I used the microupdi board you mention towards the end of your vid, and whilst it worked initially, my pro micro board is no longer recognised by the Arduino IDE, so can't upload the firmware. More research req'd :) :)
Hi. This is a very good video, however i`m not sure which chips i can use. I`ve got a lot on my Mini and Migthy Core boards but none with the PU or AU at the end. Just ATMega328 etc. Will any of these work in my project?
P stands for the low power version and might not always be printed on the chip. Mini-Core boards and Arduino Nano''s both use Atmega328 chips in the QFN32 format. If the chip is already soldered into the Mini-Core board then I'd recommend using online tutorials for that board.
Both the Atmega and the Programmer are powered from the breadboard power supply. Pin VCC on Pololu AVR programmers are set as an input by default. (This is different from video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-VVK0aYcrnQc.html where the programmer powers the circuit).
Yes, the MOSI and MISO connections are a type of serial interface. However, I don't think you can program the Atmega directly to the serial pins without a programmer.
Get a thin wire, solder it on the pins needed, solder the thin wire onto some female or male jumpers, no need to pay 20 dollars for something you will only use once.
Fixed my issue, just had to use avrdude. This all gets a little confusing because most people use this for the ATTINY processors and assume an unlocked state or download a bootloader. It just wasn't clear to me initially that avrdude was included in arduino or how to access it initially. Also the pins dont match up for the 40 pin 4809? idk im looking into it (probably just missed a paragraph somewhere again)
Hey, I am working on a small project that requires this chip, but I can't find it anywhere would you be able to provide a link to where you bought it? If not, would all the libraries and devices you used work to program an ATmega328P?
Yes, all chips seem be be hard to find these days. Unfortunately the UPDI programming method doesn't work with the Atmega328P, but I see there are currently 5 Atmega4808's available at Mouser for $1.68 each. You might want to buy 1 or 2. Looks like there will be more available in February. www.mouser.com/ProductDetail/Microchip-Technology-Atmel/ATMEGA4808-AU?qs=P1JMDcb91o4OSr3c6aXxLg%3D%3D
may you have a great day Sir, Sir please let me know that this circuit using 16Mhz Crystal Oscillator and 22PF capacitor will work with Bluetooth as well. because my circuit with same programing is working with Arduino UNO but when i try to use atmega328, oscillator and Capacitor it not accept any command.
