Zhang family portrait, are at work we used several downloader. Hand to these, there are several others in limbo.
One by one to talk to you for reference, not to discuss the parameters, not the whole of that imaginary egg with the actual use of experience was important, after all, the heart was hand along the smooth.
J-Link
Famous, various versions, different styles, up to the amount of support chips. But remember not to pick the version in the upper left corner of this map, very worried about the wrong handle it one day squeeze broken.
Suitable scene: If you make the project files are large, choice, fast and steady download, simulation debugging is also a lever artifact.
- Pros: The fastest, steady as an old dog. Found STM32F407 chip 8 seconds + 109K codes burn-in process is completed, the downloader FIG., The number of the fastest it.
- Disadvantages: most expensive, harmonious version of the four or five yuan start, genuine to several thousand dollars. Note: Most V9 version following J-Link does not support STM8.
ST-Link
With several years of monopoly STM32, ST-Link also fire properly due sales of a brother.
To suit the scene: the highest price, most brothers in school suit. Because the brothers more than generous attempts, by opening out the bad people also! Joking ~ ~.
- Pros: Cheap, cheap, cheap! x Bao 13 yuan shipping. KEIL driver package in a folder inside the file itself.
- Disadvantages: not stable enough, from time to time to a pop!. Why is instability? 13 yuan shipping business, the devil knows how to fight out!
CMSIS-DAP
Fairly new thing. Because more and more open with people, it is because a lot of people know little new technology and Li Chong EDA open source project. Slightly more expensive than STLink.
Suitable scene: stm32 of play, this is the best choice.
- Pros: Open source, virtual serial port, free drive. Love virtual serial port, so cool, so cool, (some also download virtual serial ports), but did not love it open heart ~ ~.
- Disadvantages: nothing disadvantage compared to ST-Link, cheaper, more stable, no copyright issues, compared to J-Link, 109K code is measured burn for 10 seconds, it is not too slow.
DAP-Link
CMSIS-DAP upgraded version.
Suitable scene: ah, if your ability superb, the most appropriate hardware and software are open source, high playability, such as to be a drag offline download ......
- Advantages: Drag burning, upgrade firmware. Including the advantages CMSIS-DAP: the open source + + virtual serial port to avoid flooding.
- Disadvantages: Do not buy this map in the lower right corner, you will find very smoothly, block line of sight, afraid to pick the wrong line when connected Du tie, impractical, two hand went into limbo.
ULink
- Has been very curious, because open Keil download selection list, which accounted for the first three options! ! On the frequency of use, useless how many people use (x amount of treasure rarely show), on letter rankings also far from it, then it neatly Pa his head three seats it for the hair? ? ? I love CMSIS-DAP and artifacts J-Link had to be honest it came in the rear end? This guy in the end a few two kilograms of?
- Unfortunately, I did not used, downloader hands head too much, can not find reason to buy.
Use Summary:
- Play STM8 / 32, and what dim. I did not need more than what the parameters. 109K code, download a twelve seconds difference is I do for you, not to mention most of them are dozens of K. Buy it the first choice CMSIS-DAP, pass to kill Cortex M0 / M1 / M3 / M4. Not the legendary seconds STLink, but 20+, compact and stable, really easy to use.
- Play Cortex A5 / A8 / A9, the first choice for J-Link! ! Note that the goods are not genuine homemade, pay attention when the pick, do not turn your turn dry expensive chips.
- In their work, there is CMSIS-DAP playing board did not own a shell, did not stand to look good family portrait inside the top, bottom reissue a photo essay. Many unknown error when downloading other downloaders do not weigh in with a big chance of success it can always download, do not know why, after use will be specially element back into the box, I feel it is their trump , was well protected, ha ~. Actually that J-Link with a minimum of actual road, although it always feels a little faster a little bit, but with the accustomed convenience CMSIS DAP.
- Further, there is a veteran embodiment, usually set of circuits, when adjusting module's need to download I! ! Because more direct: integrated development board downloader! The brothers spent most clearly, peace of mind save time when this type of development board province, is set weapon program, to avoid a lot of unnecessary time cost, debugging errors. Hand common witch technology F429 development board with wireless communication, 130 +, less than a JLink expensive, and integrated or own love of CMSIS-DAP (pick when the attention of some development board integration is the ST-Link. Gengshuang, it routines with the GPIOSet, EXTISet, NVICSet function, similar to the atomic brother lazy style, better clarity, than with standard library does not know how much code you want to save, use digress ...... such development board, work on the desktop, leaving only a line of Android, electricity, download, serial debugging fixed up the whole desktop clean, neat work, but also to plug in the phone idle when nothing ......
