Other Parts Discussed in Thread: ENERGIA, MSP430F5132
Hello,
I had this PCB built for educational purposes, but I have not been able to get it to work. I have a few questions.
(1) SL_C is shown connected to C18 to the right of the Phase B power block. I am questioning this since SL_A is shown connected to C19 next to the Phase A power block and SL_C is again shown connected to C22 next to the Phase C power block.
(2) I am somewhat confused by the notes below the 3-phase gate driver on sheet 1 and the note pertaining to R17 and R18 below the current sensing circuit on sheet 4. I am just trying to use the PCB and firmware code "as-is", and I am not sure which components should or should not be installed based on the current design.
(3) I am also curious if there are any specific reasons why the MSP430F5132 was chosen for this design. Is there anything that makes it more conducive for this specific design over all the other variations of MS430 micro controllers? I would like to try to port the firmware code over to Energia once I can the PCB working using the program developed in CCS. However, it appears as though there are only a select number of MSP430 micro controllers that are compatible with Engeria and the MSP430 Launchpad, and the MSP430F5132 is not one of them.
Thanks,
