The MAX3740 and MAX3795 laser drivers provide a laser diode average optical power monitor output voltage. The monitor output is derived from the monitor diode current of the laser assembly. Laser driv...
I am making a phone call software on PC, using C# + MSCOMM control + AT command, and have realized most of the functions. Now I hope to get the information of each call duration. The problem is: 1. I ...
I want to ask: After AD conversion, I read the change every 400MS. The change is 50 words in 2030-2050. My input signal is jumping at +0.001V. The reference voltage is +- 0.001V (5.101-5.103). Is this...
[size=4]1.6 Interrupt Controller The ARM core only provides two interrupt vectors: fast interrupt (FIQ) and standard interrupt (IRQ). However, each semiconductor manufacturer adds its own interrupt co...
There is an array uint8_t buf[] = {7,8,9,1,2,3,4,5,6};
There is no need to judge the values stored in the array. If only one variable "uint8_t tmp" is allowed, how can I quickly set buf to {1, 2, 3, 4...
