CCS/TMS320F28035: tms

Intellectual 370 points
Part Number: TMS320F28035


Tool/software: Code Composer Studio

currently i am working my project on TMDSHVMTRPFCKIT.but we have developed open source project in control suit related to this kit. when i see this code like sensor less ACI FOC, the code have PWM MACRO DRIVE AT DAC, and ADC DRIVE MACRO AT SENSOR INPUT LIKE VOLTAGE AND CURRENT SENSOR, but i do not need this driver any more my code is different from that of open source code  i.e ACI FOC, instead can i used external opamp  driver for current and voltage sensing also for DAC(can i use external DAC device), if this possible how can access ADC PIN IN this kit. i think ADC pin are not avilable esspecially for this High Voltage + PFC TMDSHVMTRPFCKIT

    Hi Tesfaye,

    Can you elaborate a little bit? What is the core question?

    My understanding is that you want to use some external device to actuate the motor or control the PFC instead of the ePWM, but you still want to use the ADC on the F28035 device for sensing? In this case you'd need to send out the ADC results via some communication interface. For F28035 the fastest interfaces are probably CAN or SPI.

    Hi Tesfaye,

    I haven’t heard from you for two weeks, so I’m assuming you were able to resolve your issue. We would like to close the thread first since you also posted another one similar question about how to use a DAC device on HV-Kit. Please let me know or create a new thread if you have any further questions. Thanks.
