The switch IC specification is uploaded. The two resistors connected to the V pin of the TOP switch chip (in the circuit structure of Figure 1) R1 and R2 resistance calculation formula refer to Figure
The installed version is CCS5.5. This version only supports software simulation of the C55 series but not of the C54 series. Therefore, I used the TMS320C5510 chip for this experiment. The process of
When doing modbus485 communication, some parameters are stored in the 430 information segment. Now the parameters are written as other collected data. This happened twice, and both times they were wri
