We improve the AVRDUDE software such that it can handle this particular situation. I looked into this with my colleague Johan - who is a true makefile wizard - but we couldn't figure it out. We find a way to implement the first two steps in the makefile anyhow. The user cannot run his project outside our IDE anymore. Hardcoding (part of) the flash procedure in the IDE itself defeats this goal. The makefile is well-explained, with plenty of comments. We provide a makefile to each sample project our users can download, but it is not touched thereafter. ![]() The user simply needs to invoke clean, build and flash targets to do all the magic. We achieve that in two ways:Īll Embeetle projects are makefile-based. In other words: if one of our users decides to work on a project outside Embeetle IDE, he/she is free to do so. At Embeetle, we have the desire to keep our users informed and free. I could just hardcode the first two steps in Embeetle IDE and run them behind the scenes before launching the third step. I know how to put the third step in a makefile, but I have no idea how to implement the first two. The flash procedure explained above consists of three steps. Do it quickly, because this serial port is only active for a couple of seconds.Īrduino IDE does it this way. Store that port name and go on to the next step.įlash the firmware through the new port (eg. As soon as the board has completed the reset, it should present itself with the serial port for flashing (eg. Observe the serial ports from the OS (Windows/Linux). COM9) at baudrate 1200 and close it immediately thereafter. Open the serial port through which the board has identified itself (eg. I observed how the Arduino IDE deals with this case: COM10) which is only available for a couple of seconds just after a reset. COM9) while you need to flash them through another (eg. Unlike others, the Arduino Leonardo and Arduino Micro boards identify themselves through one port (eg. ![]() Finally we can look into potential solutions. I'll first review how it works precisely, then I'll explain why this is a problem for many users of AVRDUDE. The flash procedure for these boards is quite complicated. So far most of the example sketch's either fail to verify with a string of errors, or contain much more than I need (8 axis 32 buttons like the one I tried).The ATmega32u4 microcontroller is present on a couple of Arduino boards, such as the Arduino Leonardo and Arduino Micro. Ive had the leonardo appear in joy.cpl as an 8 axis 32 button controller with a modified HID.cpp + USBAPI.h, but have not gone any further as to add any inputs. I understand there are limitations with the ch340g chip found on most arduino's which is one of the reasons I bought a leonardo which has a proper usb interface. I can see the potential in these products so dont worry about how many Ive got, I will make some use out of them one day. They were all so very chinese cheep I had to buy them. (Ive made Arma2 missions which is the closest Ive been to programming in C previously) I have purchased a few diff Arduino based products since my post and have been playing around with each of them learning the basics of the sketch's. Thanks for the reply's you two, I really do appreciate your inputs. ![]()
