After I learned Linux+C, I wondered whether it would be more promising to develop in the embedded field or in the network programming (TCP/IP and socket) field. I have successfully interviewed two com...
Communication - combined with the book, there are the following contents:
Digital logic of CAN communication, implicit level 1, dominant level 0CAN communication frames are divided into data frames, r...
I graduated from computer science and took the postgraduate entrance examination for computer application this year. I originally chose embedded technology. In fact, I don’t know much about this field...
Now we are making a meter reading system. Each meter controller has a 485 communication port. However, there are usually more than 50 meters in a building. A 485 bus network can connect up to 32 meter...
I have to say that the previous method still doesn't work. I have always felt very strange about this. I just read the posts and thought that one of the posts by a buddy is worth noting. However, I am...
How much does it cost to develop a chip, development environment, protocol stack, etc.? Which one is better for industrial control, TI or EMBER? Or other ones? Does anyone know? [[i] This post was las...
