Interrupts are set up to enable the CPU to handle external asynchronous events. Usually, the DSP works in an environment that contains multiple external asynchronous events. When these events occur, t...
Our company is now urgently recruiting c/c++, host computer development, DSP software development, ARM embedded software development engineers and radar navigation and other related positions. For spe...
I used PB to burn the nk.bin compiled by this project to the board and it can start normally. Then I added these three lines in config.bib: ROMSTART=80067000 ROMWIDTH=32 ROMSIZE=00b00000 The nk.nb0 ge...
This is a 4-20MA to 0-5V circuit! Let me first talk about the basic principle of this circuit! The op amp ICD (the op-07 below) is mainly used to offset the voltage on the sampling resistor R10 when i...
