I have a project on hand that uses STM8S103K3T6. After adjusting the program, I touched the IO port of the chip with my hand when I was bored. I found that if I touched the input port several times, t...
At present, I know that the frequency range of manganese-zinc ferrite is 1~1MHZ, and that of nickel-zinc ferrite is 1~300MHZ. You are welcome to add or correct me....
Overall analysis, the formula data proves that the ability to complete the measurement work mainly depends on the input voltage, how the reference voltage is related to the level flip, and the role of...
I am using the EPI of the LM3D9B92 chip to drive an LCD. I am planning to use the HB8 sub-mode in the Host Bus mode. In addition to the 8 data lines, do I need address lines in this mode?...
TI's documentation changes the high and low of SCL and SDA by setting P1DIR.Why not set P1 as output and thenset SCL and SDA to 0 or 1 by changing P1OUT? ?...
