Microcontroller ISP Programming (getting started)

Nice to learn, keep working chris..

Thanks 🥰

Cool video Chris! I also think about one more thing: With CH340G, you can program and also do serial monitoring (e.g. viewing the sensor data through USB), so it works in both ways. Can you do the same with USBASP? Because as I see, it works in one way and it it just for programming.

[@DIYGUYChris]

You are correct. While USBASP is capable of bidirectional communication, it does not involve the sharing of serial data. On the other hand, CH340 functions differently as it acts as a USB to Serial converter. It allows the establishment of a USB communication port between the computer and the device, which is not the case with USBASP. In the case of USBASP, it utilizes an ATmega88 or ATmega8 that comes preprogrammed to serve as the programmer.

Great video! What is the size of the copper dots where the pins connect to in the 1.27mm variation?

[@DIYGUYChris]

Thanks. The ISP spot size could be defined by yourself depending on the PCB manufacturer capabilities, as for JLCPCB the minimum clearance for two pads of different nets is 0.127 and considering the spot spacing of 1.27mm then the spot radius could go up (1.27 - 0.127) / 2 something around 0.55mm 😉

Chris can we use esp32 ble or wifi as programmer? What i need is one esp connected to computer and push the program to other esp which is programmer of the target board

[@DIYGUYChris]

I highlighted that you need an ISP programmer as hardware and an app that supports the used hardware. As for ESP maybe you want to take a look here : github.com/lbernstone/ESP_AVRISP And let us know if you come up with something useful 😉

Interesting tutorial you demonstrated, I have a curious question, I know usbasp can be used on Arduino Nano, but my question is: can usbasp be uploading files to Arduino pro-mini? I don't know if this works? Both Arduino Nano and pro-mini have Mosi, Miso, Clk and CS port. Thank you.

[@DIYGUYChris]

It works almost with all AVRs, yes you could do this and one more info about Mini and Nano they have the same MCU Atmega328 so it is basically the same thing

@@DIYGUYChris Thank you for kindly response, I will try my projects if I have time. Again, Thank you.
