520K RAM is huge for most typical embedded apps. Most micros are typically around the 48K->128K SRAM.

This isnt an x86 emulator that can run a DOS box, this is NT running natively on PPC. So... no DOS games I'm afraid.

Agree... As an embedded developer for over 25 years, I would never use the provided hardware abstractions from one particular vendor. Typically, you use your own abstraction layer over multiple vendors BSPs/OS/libraries. One of th

true, my point being that "printf not working" is nothing to do with FreeRTOS.

You still didnt define what "cursor addressing" means. Its not a common term to use for these UIs and doesnt seem to get to the crux of what separates a typical GUI from these. For me, the crucial difference is that they're u

This is a microcontroller (Cortex-M) not an application processor (Cortex-A).

FreeRTOS has nothing to do with printf, thats a toolchain/standard library thing for his particular board.

If you're buying it... could you return it? If so, how would they refund you without an account?

You're trying to see a small change over a large fuzzy area. You need to look at the deviation from the mean (or some other reference), maybe filtered to remove the seasonal changes.

If you're doing that from user space, the noise will be from scheduling delays as Linux context-switches your process to run other stuff. You can minimise that type of effect thru use of cpu-affinity but not get rid of it completely.

You would have to ensure each bonding-channel was on a separate RF-channel, otherwise instant collisions.

GPS chipsets use Kalman Filters, its standard practice. I think you have an incorrect perception here.

The ability to explain yourself clearly and precisely in the written word is a skill not much appreciated by most engineers (sadly).

This is sqlite, not a db-server like mysql, its an in-process db that forgoes those sort of issues in the name of performance and lightness.

ctrl-z doesnt kill the runnning program, just puts it to the background. The process is still present with all RAM still held by it... you ca use "fg" to bring it back to the foreground. I think you meant ctrl-c which kills the pr

ARM is most dominant in the microcontroller space with the Cortex-M devices. Literally billions of them are made every year. https://www.arm.com/company/news/2021/02/arm-ecosystem-ships...

Its useful to show how much waste there is in a solution. Having an operation that can be executing 250,000 times per second on a modern processor is extremely slow ... not fast.

by TickleSteve 4y ago
So, 250,000 per second on a (roughly 10,000 MIPS I7 core) Each of those task_create calls is roughly 10,000,000,000 / 250,000 = 40,000 instructions. Thats 40'000 instructions of pure overhead as it does not contribute to the task

i.e. Approximate vs precise. But, there is another option. The tool (presumably AI/ML based) that takes the ad-hoc query and turns it into a precise query to the structured-data tool in order to return precise results. I hope that this
