  • TMS320F28054M-Q1: Material：TMS320F28054MPNQ

    Part Number: TMS320F28054M-Q1 Phenomenon: When the program is running, the motor itself will emit an electric current sound. As the voltage increases (12V, 24V, 48V, 110V, 600V), the current sound increases. The customer speculates that the phenomenon…

  • RE: TMS320F28054M-Q1: FAST&motion related issue

    Could you please provide more details about this question? Which board? TI EVM kits? Or customized board? Which lab is using? What motor parameters? What PWM frequency? Share the user.h please?

  • RE: TMS320F28054M: TMS320F28054M

    Do you use the CSM on this device? And are using the isolation JTAG debugger? If you have initialized all of the using variables, seems like there is any further update for you if you didn't use the CSM. Milind Bapat said: If I use run mode instead…

  • RE: TMS320F28054M: TMS320F28054M

    Thanks for posting the contents, I don't see any thing that is in violation of the memory map. As an experiment, in Uniflash instead of picking the F28054 device, can you configure Uniflash as if you were using the F28055 device instead, to see if…
