At present, with the development of ARM, the main frequency of ARM is getting higher and higher. At the same time, ARM has a price advantage over DSP. Therefore, more and more ARM+FPGA control archite...
The principle of encoder speed measurement: Everyone knows that in a closed-loop servo system, the number of feedback pulses from the encoder is proportional to the position of the system, but not man...
I am designing a GSM wireless temperature alarm based on Beaglebone. The temperature sensor is DS18B20 and the display is 1602. Now 1602 can display normally, but DS18B20 cannot detect the initializat...
Let me talk about the environment first. I use Vxworks5.5+Tornado2.2. The BSP is Pentium4. Because there is no Pentium 4 machine, I use VMware to virtualize a machine on the machine. The compiled self...
Dear experts: MSP430F2012 has its own LF oscillator circuit. As long as a crystal is added to the external XTin, it can be started to oscillate, thus providing a clock for 430. Can a high-temperature ...
