I have a question. If a subroutine is not called, will it not occupy program space?I removed several uncalled programs, and after compiling, the program space occupied remained unchanged.
Please give ...
On March 25, we will introduce the industry's first high-speed isolated USB repeater that complies with the USB 2.0 standard. Our isolated USB repeaters can help engineers design more powerful and rel...
From the P1 port diagram provided by TI, the output of P1OUT.0 is not affected by P1REN.0. However, if you do an experiment, you will find that this is not the case at all:The following analysis uses ...
I don't understand the description of NWAIT in the datasheet. Is it like this? For example, for an external FPGA, after EBI outputs a read command to the peripheral, the peripheral FPGA pulls the NWAI...
I would like to ask how to calculate the pull-up resistor of an OD gate. Why is n the number of load gates instead of the number of input terminals for a NAND gate load? See the figure below. I am a n...
Because you want to DIY a fast-charging version of the constant temperature soldering iron, in order to achieve wide voltage inputs such as 5V, 12V, and 20V, you need to use a boost chip. By using the...
