The main reason I fixed this was that prior to this fix, you would have to physically unplug the device and plug it back in to get the host to re-enumerate and 'talk' again, which made doing updates a bit of pain. I can envision that there could be issues when using the official Fischl USBasp f/w in this environment.

#Micro snitch startup code#

The official Fischl USBasp f/w will not force re-enumeration on startup as the code that was attempting to force the host to re-enumerate was improperly handling the USB signals so it would not work.

#Micro snitch startup update#

Should the bootloader start first and enumerate as a USB device and then start the application image (USBasp f/w image) or be used to update the USBasp f/w image, the USBasp f/w image will force the host to re-enumerate correctly as a USBasp device with its usb descriptor parameters as soon as it starts up. The new USBasp f/w that I've been working on will force a re-enumeration by the host when it starts up.

kinda like dual boot windows and mac in a one computer, or something like arduino as ISP, but much easier to use. Here is the simple concept: there are 2 memory sections in avr: bootloader and main memory We will have Usbasploader in bootloader, and there is no reason why you can't load an Usbasp program into the main memory and use it normally as a usbasp. So it works now? it should work as a regular usbasp too. its a wonderful project and was just as easy to setup as digispark thanks again for a great idea. So its working great as a self programmable m8 module which is very useful if there is no other programmer available. i think it makes less sense to have this anyway because that code goes away after first use. So it fails to work as regular usbasp but this is not important. select juno, upload with programmer, and led sketch runs. Ignoring the normal usbasp mode problem and resetting with j2 short it does work properly as virtual usbasp. when plugged in it does not negotiate as a usb device but give the not recognized error regardless of j2 so thats not working. I did not get far enough to press reset after seeing that message. I also develop a board with this Usbasploader setup. This bootloader is better than digispark. You can still use all the pins, but itвЂ™s risk since that pin is grounded, writing a high to it will short it out. Once you uploaded your code, to upload again, you also need to press the reset button again. Then the вЂњusb device not recognizedвЂќ will turn into Usbasp. There are 2 modes: 1, normal program mode 2 boot-loader enable with virtual Usbasp mode.ДЎ,When you powering it up, it will go to normal program mode, regardless.Дў, To enter Virtual Usbasp mode, you need to shorted boot-loader enable jumper, plug it in, then press the reset button. Remove j2 and short j3 then replace programmer with the target usbasp.

actually would then have 6 io for user w/o mods not 4 counting j2 bit too. why short j3? other objdev methods do not require this and it seems odd to delete this potential io. I would be interested to hear of independent success using same procedure.ДЄnother question.

any suggestions what i may be doing wrong? Regular programming firmware and the led blink program work fine if flashed directly into the same usbasp using normal isp. Usbasp_hack_Usbasploader_Atmega8_fd_.hex flashed. On target usbasp j2 shorted j3 open and fuses changed under xp with libusb_1.2.4.0 using normal usbasp.

However for some reason i am unable to get yours to work: i usually just connect to another usbasp but also had success with digispark type setup although not as convenient because of the button push annoyance. i often use usbasp as controllers and think its use beyond regular programmer is underestimated.

Writing high to this pin will short out the pin.
