So my advice is to never rely on those libraries being up to the job. These libraries are designed to lure in developers by showcasing some capabilities, but they seldom get anywhere near the optimum performance of the silicon. That would have cost my customers huge amounts of money. If I relied on those vendor libraries for either of these products they would have either been abandoned or would have had to be massively redesigned to use far more expensive and more power-hungry circuitry. End result: dig through data sheets and write my own functions. The DMA library just glosses over the more useful DMA settings (burst size etc) causing unacceptable sampling jitter due to DMA bus contention with the CPU. The USB libraries are only "hello world" performance level and are incapable of sending data at any more than about 1MBytes/sec. This device streams data at approx 12MBytes/second (read by CPU doing 250k interrupts per second) into buffers from which it can be send by USB.

The second is a system based on an NXP LPC43xx. Spend a bit of time looking at the data sheets and figure out the direct register calls you can get about 17MHz. With the "warm fuzzy" libraries the fastest square wave you can achieve is about 4 MHz - not fast enough (absolute minimum is 12MHz). This project needs to generate quite a few different signals not supported by peripherals by bit-banging GPIOs. Two examples from projects I'm currently working on: are using a 70 MHz 32-bitter to do things we would have done in the 1980s with an 8-bitter). Very seldom do these libraries actually make for the useful basis of a product unless you massively over compensate (i.e. These libraries are designed to make the part look very simple to use and therefore encourage their use. I have a very different experience from vendor libraries and embed etc than Jon does. I gave up on the latter long ago.Ĭharles Manning is unhappy about the overhead in some of these libraries:

Energia, and now mainstream Arduino IDE 1.6.10+ with Energia libraries, is a better way to go for playing than CCS. Paul Carpenter wrote a long note about this issue here. Jon Titus' laments about the pain of getting an MCU configured generated a huge number of replies. We Need Simpler Ways to Access I/O on MCUs - Redux So, at the end of February, 2017 we'll award these to two lucky contest winners. He feels these address the issues Jon Titus identified. Andy Nevill of Cypress sent a couple of CY8CKIT-044 PSoC 4 M-Series Pioneer Kits (Cortex M3 based dev kit with Capsense, Programmable Digital (CPLD) and programmable analog) for the giveaway. The work isn't complete and new releases are planned.Īs noted below, a lot of people express frustration with vendor's libraries and tools.

Although there are always areas to be improved, we do care about the documentation, software architecture and the user experience. The development team is doing its best to deliver the product with quality built-in.

So far, Windows and Linux platforms are supported and one can download binary files or installation packages. So it makes the tools reserved for RTL engineers useful also to firmware people. It just transforms textual logs into VCD (Variable Change Dump) format files which can be easily viewed and processed by any VCD viewer available on the market.

Surprisingly, this is not a graphical tool. It allows for easy visualization of textual logs firmware engineer tend to create to analyze their systems behavior.

The tool is free and open (available on the GitHub). Wojciech Rynczuk writes about a tool he and his colleagues wrote: Here are the tool reviews submitted in the past. Please submit clever ideas or thoughts about tools, techniques and resources you love or hate.

"Don't comment bad code - rewrite it." - Brian W. The Navy said that showed the part was too strong, and thus too heavy. In the 1950s his company got into trouble because the tests wouldn't fail! The Navy want the test to break a tail assembly on a fighter jet, but it was so strong it wouldn't break. There are a lot of insights into this issue, but here's one amusing (and true) story: My dad was a mechanical engineer. See for more details.Ī number of people commented on last issue's quote which advocated using test to stress a system's margins to see if the system would work.
