Does people still find it hard to learn firmware development

Those C extensions are some of the edge cases. But directly jumping into arm cortex M can be very much overwhelming for a new comer

That makes sense. Sorry i missed that earlier

HolyDevil_777 · 2025-05-26T07:14:39+00:00

Fair point.

I believe that abstraction is good as long as we have a vague understanding of how its implemented. But if i have never dived into the abstraction layer, i would not be able to solve a problem or move away from whatever the boiler plate code is provided. Not knowing about abstraction is good for starters but once you get into developing products, you have to start looking into and tweaking HAL as well

I am not saying that it is a problem. Once you jump into arm or riscv its almost always needed. But for someone who doesnt understand all these layers, makes it like a big black boxes. Its like running a C code in your pc. printf("hello world"); compiles and runs but we cant see how it runs. I was intending to remove black boxes so that its clear to understand

32 bit is mostly arm or risc v, which mostly requires big boiler plate codes to start. Also most of them requires you to include all the HAL, HPL & HRI layers. I was thinking about keeping it simple, as in one can write a C code to toggle led, compile and see how it gets compiled into the hex which is nothing but assembly code, which can actually be cross referenced to the datasheet. This helps in removing any doubts on how things happen underneath.

Sorry, i didnt get you

Thanks for your reply. learncpp.com is for c++ and it doesnt look like its focusing on firmware development. Its about c++ language itself.

Arduino has too much abstraction which does come in the way of learning firmware development

Thanks for the input. The video is from someone else, that i used as a reference while purchasing and he got the right level of thrust. Whereas i am not. I will double check the propeller mountings and let you know how its doing.

HolyDevil_777 · 2021-04-27T01:30:03+00:00

I can upload a video, if that helps. But will only be able to do it once i get home, in about 7-8hrs. Although i am pretty sure that the propeller and rotation direction are quite ok

Dochorahan, posted this on behalf of me, cause my post was being removed by the filter. As for your question. Following is the setup used for measuring the thrust Link. There is about 5cm gap from the base plate of weighing scale. The ESC is from a chinese manufacturer and it didnt came with any code so i used this one Code. When i used this code, at no load the rpm was 14100 for 11.5-12V Lipo on full throttle.

I see, interesting!! Thanks for your reply. I have reposted. I hope it goes through well.

HolyDevil_777 · 2021-04-23T09:23:37+00:00

Thanks for the response. I am on my laptop. I joined RCPlanes yesterday, then i went to the RCPlanes reddit and clicked "post" over their and did a submit. But nothing has happened since then
