My last post stated that Atollic got acquired by ST Microelectronics. The new TruStudio would be free courtesy of STM. I just got the message from my contact that gave the link to the download for the latest version of TrueStudio. It’s not up on their website yet so this is an early present for everyone looking forward to this. Enjoy!
I’m about to start a new project using STM32F4x ARM Cortex M4 from ST Micro. I was planning to maybe get Keil uVision 5 since most of my training had been done using Keil. I have explored other options like a bunch of GNU tool chains and such but found them to be really annoying to put together and many times don’t work real well especially with ST ARM devices. I came across Atollic TrueStudio Lite a while back and I really like it. All my codes that were written in Keil uVision 5 compiled with no issues using TrueStudio. I first started looking at Keil uVision 5 pricing and it’s $5k for a node lock perpetual license or $9k fro a perpetual floating license. Maybe I could convince work to buy the license, but after spending 17K on Altium Designer license and subscription I don’t know whether I could get Keil license too. Fortunately, I went to Atollic website again to see how much a TrueStudio Pro would cost. I found this news announcement:
Basically, it said that ST Micro just acquired Atollic and they’ll make TrueStudio Pro FREE!!! Wow! I can’t wait to try the Pro version since the Lite version was pretty good (except for the annoying long loading splash screen at the beginning). Some people might say the TrueStudio is still technically a GNU compiler and Keil would be a better tool. Nevertheless, I don’t think you can beat a free professional tool. Even TI made their Code Composer Studio free a while back which actually annoyed me because I did pay for the license just a couple months before they made it free. I did consider using MSP432 since it’s also an ARM device, but you don’t have the freedom to clock it to 400 MHz like you can with ST ARM devices. The STM32 Cube tool was decent but it’s annoying without having a decent IDE to use it with. As I mentioned before, I tried to roll my own GNU tools, but the success of compiling the codes from STM32 Cube was questionable without a lot of manually fixing a lot of things. It works well with Keil and TrueStudio right out of the box though. Now I can see an even better integration between ST software and TrueStudio going forward. Maybe they’ll bundle STM32 Cube already inside TrueStudio and it’ll be a one-click code generation. That would be incredible.
Free good professional software is the name of the game these days. That’s really the reason why I picked Atmel products over Microchip 10 years ago. Atmel has Atmel Studio which was a quality C GNU compiler tool for free while Microchip charged you a lot of money to use their C compiler.
In any case, looks like I have a perfect solution for my ARM Cortex M4 project.
