1. Change in Magnitude of Differential Output Voltage and Change in Magnitude of Common Mode Output Voltage are the changes in output voltage
when DI input changes state.
3. The transceivers are put into shutdown by bringing RE high and DE low. If the inputs are in this state for less than 50ns the device does not enter
shutdown. If the enable inputs are held in this state for at least 600ns the device will be in shutdown. In this low power mode most circuitry is disabled
and supply current is typically 650nA.
4.Hot-swap circuit adds pull-down resistance to first DE or RE transition.
The following is the McBSP program to implement the asynchronous serial port, mainly to debug the DSP (TMS320C5410) to send data.
However, I cannot see any data using an oscilloscope or the serial por...
Hello everyone, I recently used the lps22hb chip and found that the pressure value I read was wrong, only 0.7kPa, and the temperature value was correct. The official provided the read_data_simple.c ro...
