Non-profit educational purposes means that you may not use the J-Link EDU and its J-Link software You may use the J-Link EDU for non profit educational purposes only. Debugging limitations inherited by the number of hardware breakpoints (2 on ARM7/9, 4 on Cortex-M0 and typically 6 on Cortex-M3) are completely removed. The Flash Breakpoints option allows the user to set an unlimited number of breakpoints within a device’s internal flash memory. Via GDB-Server, the supported tool-chains also include Atollic TrueStudio, Yagarto, and other GDB based or compatible development environments. The J-Link EDU is natively supported by IAR EWARM, KEIL µVision, Rowley Crossworks, and CodeSourcery G++. The only limitation is that it may not be used to develop a product. The offer includes free use of Flash Breakpoints. J-Link EDU is available for everybody who does not use the software to develop a product for sale. Banging the hardware is only tenable if you are a masochist with a lot of time to waste, or an expert who has already built up their own codebase.JTAG/SWD Emulator with USB interface for educational use, SeggerĪ package for educational pupose, which includes J-Link with a license for Flash Breakpoints.

In the past it was different because the HAL was poorly documented and CubeMX was full of bugs, so some of us tried to work without it - and failed. I could never do that without this technology. Today I create large projects with STM32 thanks to CubeMX + HAL

Then you have a choice - learn the hardware and write your own code (preferably using the same HAL system), wait for ST to update the HAL, or go to another MCU with better support. There may come a time when either the HAL libraries can't do what you want, don't have the performance you need, or have bugs you need to work around. By going through the Hardware Abstraction Layer you are shielded from all that and can concentrate on application code, which will then work without modification on different STM32 chips. They don't want you to bang the registers directly, because then they would have to document them properly and you would have to know about any differences between devices (including hardware bugs). It's just.better if you compare the price and what you get.ĭo STM assume that working with registers is not necessary when I use Today I create large projects with STM32 thanks to CubeMX + HAL libraries. Should I program a STM32 with registers or should I use CubeMX + HAL libraries? Notice that this is a 32-bit microcontroller of tons of documentation and not a simple AvRTiny8.
But I'm worried if I become "stupid" if I use CubeMX + HAL just to make it easy for be.
I have no problem to use SMT32 with CubeMX + HAL libraries. Well.that's great! But do STM assume that working with registers is not necessary when I use STM32? Now is like "You want to create a STM32 project? Well, you never going to use register anymore so we choose for you! Here, have a CubeMX with HAL-libraries project! Ready to run!" There is no "Create a blank ARM project in C" as it was before. Great! That's really good.īut.to create a project for a STM32 microcontroller, you need to create a CubeMX project. Seperate software in other words.īut today Atollic TrueStudio and CubeMX is merged together into one software.
Before I have to download both Atollic TrueStudio and then CubeMX. But today I upgraded my Atollic TrueStudio and STM have implemented CubeMX into Atollic TrueStduio. Super easy and super fun!Īnd now my real question, why I started this question. Luckily STM offer CubeMX so the user can setup a complete project with HAL-libraries without using any registers. They do require more knowledge about C programming and what a microcontroller can do, because you can do more with STM32 than Arduino.Īnyway! I have tried to blink LED and read digital inputs e.g toggle with a STM32 by program it with registers. I quit using Arduino and starting to use STM32 because they are more cheap, faster and just better microcontroller. I have been using Arduino for a long time.

Do I really need to learn how to use registers when I program a microcontroller?
