#Arduino leonardo pro micro atmega32u4 serial
I am assuming that MOSI on the Pro Micro goes to MOSI on the SD Card, and MISO goes to MISO (etc), and that you don't swap them around (like serial transmit to receive). also found SS in pins_arduino.h under the SparkFun board info. I have also hunted around and found references to changing the SS_PIN in Sd2PinMap.h. Also using a slightly modified CardInfo program from the SD Card demo. So whatever is stopping the Sparkfun board from working has to be to do with the bootloader.and that's what I'm trying to figure out.Using a 5v Pro Micro and going to the 5v input on the sd card. However, the Deek-Robot "Pro-micro" and the Sparkfun Pro-micro appear to be using identical hardware and board layout - the pinout, component placement and silk-screening are 100% identical apart from the logo on the back and the color of the board itself. That would certainly lead me to believe that the Sparkfun Pro-micro and the Leonardo are incompatible with each other for some reason. The problem is that the Sparkfun Pro-micro doesn't work with that setup. Sparkfun describes the Pro-micro as Arduino-compatible ( ) - and the Deek-Robot clone of it certainly is.

It also runs my software perfectly and interfaces to my project hardware through A0.A3 and D10.D13 just like the Leonardo. So, yeah - the Pro-micro is a tenth the size of the Leonardo and is clearly a different board layout - however the Deek-Robot Pro-micro clone works great with the exact same ".hex" file and avrdude parameters, and plugged into the exact same USB port as the Leonardo.

Since neither of those boards need the double-reset to get them into download mode - I imagine that perhaps the Sparkfun board has a newer bootloader or something? I've tried doing a double-press on the reset button - but that doesn't seem to make a difference. Software Version = 1.0 No Hardware Version given. There isn't anything else on my machine that could be accessing the port.Īvrdude says that both the Deek-Robot pro-micro clone and the Borderless Electronics Leonardo-clone are:įound programmer: Id = "CATERIN" type = S When I look in /dev, the ttyACM0 device exists and has a timestamp that corresponds to the time I plugged the board in. The stock arduino IDE has similar problems. It says:Īvrdude: ser_open(): can't open device "/dev/ttyACM0": Device or resource busy I use this to upload to the machine:Īvrdude -DV -p atmega32u4 -P /dev/ttyACM0 -c avr109 -b 57600 -U flash:w:Blink.hex:iīut the same avrdude command doesn't work with the Sparkfun Pro-micro board.

My build scripts, uploader and all of my code run perfectly.absolutely identical to the Leonardo. The Deek-Robot Pro-micro clone works great - it seems to be 100% compatible with the Leonardo-clone. The two pro-micro boards look absolutely identical except that the Deek-Robot is blue and the Sparkfun is red. A Pro-micro-clone (from some place in China labelled "Deek-Robot" - with both the 3.3v and 5.0v checked?!?).A Pro-micro (from Karlsson Robotics - a Sparkfun board - with the 3.3v box checked on the silk-screening).A Leonardo-clone (from the Borderless Electronics $9 Arduino Kickstarter).Hence I ordered two Pro-Micro's (from different sources) to play with. But for the production system, I plan to use a Pro-Micro. The project is a complicated thing with software in the PC, on a web site and in the Arduino - so using the IDE is inconvenient.hence I'm using Makefiles under Linux so I can type "make" and have all the parts of the project update/upload/etc together.Īnyway - all is well with the Leonardo prototype - it works perfectly. I've been developing a project on a Leonardo-clone.
