In-system programming (ISP) refers to the ability of chips to be programmed while installed in the system.

In-system programming (ISP) refers to the ability of chips to be programmed while installed in the system. This is usually accomplished by connecting to a 6 or 8 pin header on the board and a hardware programmer connected to the computer.

When using Arduino Uno as ISP does "Yikes! Invalid device signature" mean a bad connection, bad config, or bad version of avrdude?

I'm using an Arduino UNO to program a pre-compiled hex image to an ATTINY45, using the avrdude in the Arduino IDE directory, on Windows 7. The Uno has the ISP sketch loaded from the examples directory and that works- the heartbeat LED pulses…

Arduino as ISP without a computer

Has anyone seen or know of a method of preloading (using a computer or whatever) a firmware as data onto one arduino set up to operate as an isp and then using that arduino plug the isp interface into another and upload the firmware. To be clear -…

Problem programming Mini Pro via Arduino as ISP

I just picked up a pair of Arduino Mini Pro 5v clone boards (Inland, sold at Microcenter, currently $4 USD) and I wanted to use my Uno as an ISP like I've done with ATmega328 and ATtiny85 chips before. I've programmed the Uno with the instructions…

Male header pins on Arduino Uno

On my board, there are 12 (2 groups of 6, each group consistent of 3 rows of 2 pins) weird male header pins. What are these, and how would you use them?

MicroSD interfering with ISP programming

I have a microSD connected to an Arduino and I can't program it over ISP without removing the SD card. Does anybody know how to prevent the SD card from interfering with the ISP programming? Details: This is the microSD breakout:…

Why was the Atmega16U2 used on the Arduino UNO as a USB to Serial converter?

This is the first time that I realized that extra SMD IC near the USB port of the Arduino UNO is actually a fully fledged microcontroller, I thought that it was just a USB to Serial converter. Further research into this chip left me with more…

I bought USB > FT232RL, can I use it to program a bootloader onto an Arduino?

I bought this thing off of eBay: eBay Link Will it allow me to program an ATmega[xxx] (Arduino clone) with a bootloader? --> If so, how would I go about it? What should I do, and what should I certainly not do? --> If not, what do I need (or…

Can I program a factory fresh Atmega328P through UART pins without burning a bootloader?

Can I program a factory fresh ATMega328P using the UART pins without burning a bootloader? These pins are TX, RX, VCC, GND, and DTR pins in the schematic below. They are not the ISP/SPI pins 10-13. Arduino Pro Mini schematic For example, if you…

Changing pins used in ArduinoISP example

I have built my own ATTiny programmer, but made a bit of a mistake along the way - I didn't align the headers properly, and now instead of them plugging into pins 10, 11, 12 and 13 as per the ArduinoISP example - they now plug into pins 8, 9, 10 and…

What's the difference between ICSP vs ISP?

I'm not sure if these terms are interchangeable or not. What's the difference between ICSP and ISP? Is it simply the reset? I've shown two configurations in this question I just asked. Are they both ICSP?

Programming an AVR using ISP

I am trying to program an atmega with arduino sketch using ISP only (mac user). So I know how to burn a boot loader, and then to program the chip using the TX, RX. But I would like to program it directly using ISP, without a boot loader. So I am…

Extend program space by getting rid of bootloader on NANO

I just have a complex program that runs on a NANO. Now when I use my printlns for debugging I am running out of memory. I read about using a programmer to get rid of the bootloader that uses 2K space on a NANO. I bought an USBTinyIsp and got it to…
