28335 ADC overvoltage protection circuit
First of all, does the ADC of TMS320F28335 need an accurate 3.0V overvoltage protection circuit? From the principle block diagram in the data sheet, I don't see any built-in protection circuit. The an
c# DDE (Dynamic Data Exchange) client program, how to set up Server and Topic
As the title says. Since DDE is a very old technology, it has been replaced by OPC. But some things still need DDE. .net no longer supports DDE. Fortunately, I found a packaged API. The following is a
LPC800-mini does not seem to be able to use Mbed
I tried to compile an Mbed program for LPC812 and changed the CPU to LPC810. The error message after compilation is as follows:It seems that there is not enough space to put the compiled code.
Will the simple setting cause assignment errors?
As the title says, in the ADS1.2 project settings, I set linktype to simple, RO Base: 0x30008000 (I checked, this address should be correct), but when assigning values to structure variables, errors a
The difference between a programmer and an emulator
I am a beginner in microcontrollers and I don't really understand the programmer's simulator. I want to know if the simulator downloads the program to the microcontroller during simulation. Is there a
MSP432 MCU realizes speech recognition technology
In a world where everything is connected, more and more electronic devices that can understand speech are coming into our sight. In devices such as smartphones, tablets and laptops with Siri or Cortan
