Part Number: TMS320F28069 Dear sir, I have to spin and control the BLDC motor usoing launch pad and drv 8302 boosterxl driver . Actually I have taken the PMSM example in control suit development studio and then tried to understand PMSM example . But i dont understand the programming method using lot of macros and state machine method of implementation. can you make to understand the program? i dont know how to change the PWM frequency in that program. Kindly thorw some light. I will be able to solve the problem. Thanking you , Warm regards sundari

Forum Post: TMS320F28375D: Building a JTAG flash programmer H/W and S/W of their own design.
Part Number: TMS320F28375D Hello, My customer requested me a sufficient information to build a JTAG flash programmer H/W and S/W of their own design. Do you agree that? If no problem, could you please suggest reference materials to develop it? The following materials are expected: - JTAG register info - Procedure to program/erase/verify the flash The target part# is F28375D and some other F2837xy. The usage is their production line. Thank you for your cooperation. With your answer I would show other solutions: - TI's faster items like XDS560 and C2000-GANG . Now they have XDS200. - \..\serial_flash_programmer, usb_flash_programmer

Forum Post: MSP430FR2355: Spy-By-Wire
Part Number: MSP430FR2355 Trying to use the LaunchPad for programming a new design which is setup for programming via Spy-By-Wire. Four wires, 3.3V, GND, TCLK, and DIO. Followed all the recommendation for the reset for the Spy-By-Wire. 47k pullup resistor and 1nF capacitor. Resistor and cap are located right next to the programming connector and the programming connector is located right near the MSP430FR2355 embedded controller. Using UniFlash for programming. Issue is that UniFlash sometimes recognizes the target device but most of the time doesn't. Powering target device from the LaunchPad board, 3.3V looks fine. Wires from the Launchpad to the target device are only about 4" long. Checked connections from connector to MSP430 and they are fine. Does anyone have an idea of whats going on. Used multiple different Launchpads and same issue. Used these launchpads on an older design (different MSP430) but uses the same resistor capacitor values and it works fine on the older design. Any suggestions/recommendations to resolve this issue would be greatly appreciated. Trying to get some prototypes up and running for a demo.

Forum Post: Linux/EK-TM4C1294XL: Porting MODBUS TCP/IP on TIVA C with LWIP and MODBUS github stack
Part Number: EK-TM4C1294XL Tool/software: Linux Hey, We are trying to port a modbus tcp/ip application on the TIVA C. We have modified the enet_lwip example code by adding functions from the raw tcp echo code from the LWIP stack on github. We are therefore able to receive TCP/IP packets when we use a packet sender, and are able to echo it back. We need to now port it with the Modbus tcp/ip stack from github so as to configure the tiva c as a client (master). Could you please help us? Also: a) Should we use an OS such as Contiki, because as of now we are using the tiva-c repository available on github. b) Since the modbus tcp/ip stack using files such as arpainet and netinet which are for linux, how do we change this for the tiva c board. Thanks Some aforementioned github stacks and repositories: github.com/.../lwip.git

Forum Post: CCS/LAUNCHXL-F28069M: Rs Identification current spike
Part Number: LAUNCHXL-F28069M Tool/software: Code Composer Studio I am trying to do ID run for a PMSM on a custom board. Hardware is verified as induction motor runs fine in V/f mode. Current,Voltage and Angle graphs are ok and match with readings from external sensors. ID run starts and completes RoverL stage (Rhf and Lhf values are ok) but as soon as Rs stage starts, current suddenly spikes to ~22 A. This triggers overcurrent protection in my high voltage DC supply and it cuts power to the circuit. Instaspin FOC guide says: Section 6.5.4 A DC current is injected into the D-axis with the amplitude defined in user.h as follows: #define USER_MOTOR_RES_EST_CURRENT (1.0) Does this mean that Id PI controller gets a ref value ? Or is actual DC current applied to the motor ? Will the PWM waveforms be a simple square wave at 50% duty cycle similar to offset estimation stage or will they be normal SVPWM type waveforms with varying duty cycle ? Any help is appreciated.

Part Number: MSP430FR2522 In my application Timer_A1.2 capture on the external capture pin, running at 16MHz TA1 CLK with external source, works fine at room temperature. Above 45C, what happens is that the interrupt handler is repeatedly called with COV bit set. Clearing this bit seems to make no difference. Upon cooling, the normal behaviour resumes. (This temperature is taken using the internal ADC on the chip, using the temperature sensor. Uncalibrated, but the value agrees with external temperature measurements).
