	Hi! I'm trying to use VisualMicro to write some code onto an attiny. I've selected 'ArduinoISP' as the programmer, and I have a board file for the ATtiny45. If I build & upload, i get Code Compiling 'TempSensor' for 'ATtiny w/ ATtiny45' Binary sketch size: 1,772 bytes (used 43% of a 4,096 byte maximum) (0.10 secs) Uploading to I/O board using 'ArduinoISP' The uploader returned an error avrdude: Error: Could not find USBtiny device (0x2341/0x49) If I deselect "Always use programmer for upload", I get this instead. Code Compiling 'TempSensor' for 'ATtiny w/ ATtiny45' Binary sketch size: 1,772 bytes (used 43% of a 4,096 byte maximum) (0.30 secs) Uploading to I/O board using 'COM3' The uploader returned an error avrdude: invalid baud rate specified '{upload.speed}' The upload works fine in the Arduino IDE.

	Hi, Please switch on "visual micro>verbose" then upload and post the output or email to info[at]visualmicro.com. Also provide the following:- 1) arduino ide version 2) where downloaded attiny cores from? 3) where/how installed attiny cores? 4) if clicking "uploading using programmer" in the arduino ide or using standard upload Thanks

	Hi, I'm running Arduino 1.6.5. I'm using the attiny cores from Code https://raw.githubusercontent.com/damellis/attiny/ide-1.6.x-boards-manager/package_damellis_attiny_index.json It's version 1.0.1. I installed them through the "manage boards" window in Visual Micro explorer. I'm using the standard upload in Arduino, and it deploys fine. Here's my verbose log.

	Hi, I have looked into this and first of all you do need to select the "'Arduino as ISP'" programmer in Visual Micro or it will show the 2nd error in your first post. The attiny definitions could be a bit better and cause some confusion. The definitions declare an "upload.tool" but the definition is incomplete and I think its a mistake. In this case the arduino automatically uses a random programmer and visual micro tries to use the standard upload.tool. (In my case the arduino tried to use the "AVRISP MKII" programmer and not the "Arduino as ISP", so the Arduino Ide failed. The 'Arduino as ISP' is certainly the correct programmer to use with the attiny boards. I can see in your report that you are not using the 'Arduino as ISP' in Visual Micro but instead a programmer with a similar name 'ArduinoISP'. So my question to you is do you have both 'ArduinoISP' and 'Arduino as ISP' in the programmers list in Visual Micro? Thanks
