[b]I downloaded a DS18B20 driver, and after pressing it on the arm board, I read the value. It can be reset, but it gets stuck after sending the temperature conversion signal, and I can't read the val...
I got the launchpad development board from the agent last week and applied for a few samples (MSP430G2232). Since it was the first time I debugged the MSP430 chip, I directly implemented the functions...
The machine is not with me, and the device selected is stratixII:AUTO. The circuit is a full adder. When downloading to the chip, it prompts that the ID of the corresponding device of JTAG does not ma...
The DM9000 network card on the WINCE platform works fine when it is pinged by the host at first, but after a period of time (half an hour to two hours, it seems to be random), it stops working and mus...
In the ADS1.2 C compiler, what does it mean if a number is followed by an L? For example: i = 0x12345678L; I have read the description of this representation in a book before, but I have rarely used i...
