This project does not include the ZigBee protocol stack, as a transitionExperimental phenomenon:
One EB2530 (terminal A) is defined as the transmitting module, and the other EB2530 (terminal B) is def...
I originally studied PC software, but now I'm working on embedded systems. I'm going to make a board recently, but I don't know much about electrical knowledge. I'd like to ask if there are any specia...
It's a very simple main program. After making the following settings, can I measure the MCLK and SCMCLK signals from the P5.4 and P5.5 pins? Then, when I single-step, the XRESET signal of my P4.4 is a...
The CE 5.0 PCMCIA driver is loaded. When I insert a CF card, the message "Unconfirmed PCCARD adapter" pops up and asks me to enter the driver name. Do I still need the driver? CE comes with a PCCARD t...
I want to make a switching power supply with an output of 200W and an efficiency of 90%. I want to use a half-bridge circuit. I would like to ask you which chip is better to use. Is TL494 okay?...
