![]() An Arduino Uno (a nano should equally work).The following components are required to perform the firmware update: To help users who need this feature, today’s tutorial will spotlight the process involved in updating the firmware on your USBASP programmer to the latest version. While features like TPI has been around for a while, using a USBASP programmer is still a problem as both old and new USBASP devices require a firmware update before they can be used. One such advancement is the Tiny Programming Interface (TPI) that allows external programmers to access the nonvolatile memory (NVM) of certain low-end Atmel microcontrollers like the ATtiny series. While this firmware-only USB driver approach increases its compatibility, it also introduces a major challenge to the programmer as it requires regular updates for compatibility with advancements in how microcontrollers are programmed. Unlike what you find to serial programmers like the USB-TTL converters, it does not use a dedicated chip as it runs on an atmega88 (or atmega8), and uses a firmware-only USB driver with no special USB controller required. It is a USB ICSP (In-Circuit Serial Programmer) that allows developers to easily upload firmware/bootloaders on AVR microcontrollers. The USBASP programmer is an important tool/accessory for embedded systems engineers/ firmware developers. ![]()
