Could you please help me analyze the relationship between the input current and the load current when R1/R2=R3/R4? I have done simulations and found that the load current is (R3/RS) times the input cu...
Common problems in debugging the TMS320C3x series?
1) TMS320C32 memory configuration: The program memory of TMS320C32 can be configured as 16-bit or 32-bit; the data memory can be configured as 8-bit,...
I would like to ask if any engineer friends have been awarded the senior surveying title? No region limit, as long as you have been awarded the senior surveying title, you can do it. No need to work i...
1. Is the external connection of 51 single chip microcomputer-UATR divided into 232 or 485? Is there any difference in wiring? Isn't it 2.3.5 in DB9? 2. Is the format of sending "start bit--data--crc-...
