This programmer is exactly the same as our other listing here: ATTiny Fuse Repair Programmer V2.1
EXCEPT that it comes with advanced mode (MODE3 or terminal mode) This mode requires a PC terminal connection using either a USBtoTTL interface or an RS232 Interface.
MODE3 Bonus Features:
Have you ever been curious to know what the fuse values are when your ATtiny device has been corrupted? MODE3 allows you to read the fuses.
Write custom fuse values. In MODE3 you can enter the 8 bit fuse values from the terminal. These values will be programmed in the device as long as it is in the supported device list (see below)
If your device supports HIGH VOLTAGE SERIAL PROGRAMMING and it is not in the supported device list, there is another option to "Disable Signature Verification". In this mode whatever the fuse values entered will be programmed even if the device has corrupt signature bytes. (this sometimes happens, most times you can still program it)
This device is an AVR HIGH VOLTAGE SERIAL programmer that is designed to program all fuses, regardless of the current state of the fuses. If you mistakenly programmed the RSTDISBL fuse, OR disabled the SPIEN fuse, or programmed the wrong values in the CKSEL fuses, NO PROBLEM! Simply insert any ATtiny from device list below and connect power. Within one second, fuses will be restored to factory settings. The LED'S will reveal the results.
The Green LED indicates programming success, the Yellow LED indicates programming error. It's that easy. No computer required!
It's easy to do something wrong when you are programming your ATtiny fuses. Sometimes the fuses just don't get programmed correctly, no matter how careful you are. I wanted to build a unit that was easy to use without using a computer, software, usb drivers, etc...
In 2008, I designed the board and wrote the code for the very first version. It wasn't very long until other sellers had copied the programmer. Even when I released an update, soon afterwards the copies were updated with the same feature.
Rest assured if you buy this item you will receive email support for any problem ATtiny devices you can't program. Just send me an email message here and I will do my best to help you successfully program your device. Once the ATtiny device is restored, you can reprogram using your favorite ISP programmer and software. NEVER WORRY ABOUT PROGRAMMING YOUR AVR AGAIN!
Another time saving feature of this programmer is the ability to preserve the flash and eeprom contents while restoring the fuses so you do not have to reprogram the code in your device. To do this, simply install jumper J1. This will skip the erase command and preserve the devices' memory.
(In this mode, the programmer will not restore the fuses if the LOCK bits were programmed, the erase function MUST be enabled.)
Some Important Notes regarding the use of this Programmer:
YOU MUST USE A POWER SUPPLY THAT EXCEEDS 14.5 VDC with positive center (not included) to ensure reliability in programming. It is a good idea to measure the output your DC power supply with a voltmeter to ensure correct voltage and polarity. I am trying to keep the cost and shipping weight down, therefore the power supply cannot be included with this item.
If the lock bits have been programmed, the device must be erased before the fuse restore operation will be successful. In order to accomplish this, J1 jumper must not be installed, therefore the flash and eeprom contents will be erased when the fuse restore operation is being performed.
Instructions will be included with your purchase. If you are purchasing this item, please check your email messages on Tindie for instructions. I recommend you read the manual before using the programmer. **
|Socket 1||Socket 2|
**The following devices are supported, however they must be directly to socket #2. ATtiny441, ATtiny841
This is the easiest and most convenient tool you will ever use!
The power supply is not included. I am trying to keep this item as affordable as possible. The extra weight involved would increase the shipping cost greatly. If you would like to purchase the power supply please send me a message.
