CCS/TMS320F28035: CAN sends data as the data to be sent the previous time

Part Number:TMS320F28035

Tool/software: Code Composer Studio

Hi:

CAN debugging encountered such a problem: After the chip reset, start sending a frame of data, assuming that the transmitted data is 01 01 01 01 01 01 01 01, the data written to the mailbox register is 01 01 01 01 01 01 01 01, the length (DLC bit) is 8, but when the CAN analyzer is used to capture data on the bus, this frame has a data length of 0 and no data segment.
 The frame data is sent again (10ms or more) and the data is sent correctly.
 Send another frame of data (02 02 02 02 02 02 02 02), the data written to the send mailbox register is 02 02 02 02 02 02 02 02, the length is 8, but when the can analyzer is used to grab the data on the bus, Still 01 01 01 01 01 01 01 01.
To sum up, the problem is:
1. The first frame sent after the chip reset is not the data in the actual mailbox register, but the frame with length 0 and no data segment.
2. The subsequent data frame is the data frame that was previously written to the mailbox, not the data frame currently written in the mailbox register.

hello

1. Where can I download dis55 and ofd55?  I want to show the disassembly code.

2. And I want to know If I save memory of program as *.out file.  Can I rewrite into other device?

3. I am worried about that the binary is cloned by bad people.  Could you give me good suggestion?

Our chip is tms320c5515, and the *.bin is burned in nandflash.

Thanks a lot

DRV8833: fPWM Current control PWM frequency = 50kHz

Part Number:DRV8833

Hi all

Would you mind if we ask DRV8833?
There is the description "fPWM Current control PWM frequency = 50kHz" on the datasheet.
Does it mean that this frequency is for current control PMW light?

It is not relation to input PWM, right?

For example, we assume as follows;
Input PWM=5Hz -> Output freqency = 5Hz.

Kind regards,

TIDA-01606: UC5320S schematic question

May 9, 2019, 8:39 pm

Part Number:TIDA-01606

Hi,

I have several questions for the schematic below:

1. why need 10ohm(R33) for the primary side 3V3, but not needed at the secondary side 12V and -5V? And why R33 is chosen to be 10ohm?

2. R10 and R50 are both 0ohm, I guess only one will be soldered in the final board, right?

If we solder R50, then there will be no negative power  supply at VEE2. Then do we still need C42, C43?

3. Why R36 and R39 are 3.3ohm? Is it chosen by calculation or by trying different value on the real board?

4. In this board we are driving IGBT with UCC5320. Are there anything different need to pay attention if we are driving SICFET? From both schematic and PCB layout point of view.

If SN65LMVD206 and SN65MLVD040 are in the same bus, will there be problem that these two MLVD transceivers has matching issue? We have concern these two devices are different devices, not sure whether it will have communication issue.

Moreover, for SN65MLVD040 RX mode, do we recommend type1 or type2?

Hi,

customer want use TPS23755 for POE. The output is 5V/2A, and also they also need 12V adapter input.

Can TPS23755 do AUX function, like TPS23753? I found that for TPS23755, AUX is used when the adapter is main power and POE as back up, I'm not sure is it can be used as AUX power?

if it is, do wen have some reference design to show it?  Thanks.

SM72442: MPPT mode not behaving correctly

May 9, 2019, 9:03 pm

Part Number:SM72442

Hi, I'm using SM72442 to supply power to a battery charger (LTC4020). My circuit has 6 different solar panels so I used one SM72442 for each one, but now I'm testing just one of them. You can see the schematic and the PCB design attached.

My device is always in panel mode (I've checked PM out pin and I'm getting the square waveform). I'm testing wit a solar array simulator as input (Agilent E4350B) and a DC electronic load (Maynuo M970), I've tried with different solar array curves (Voc=2.65V , Vmp=2.35V, Isc=0.4613A, Imp=0.4456A and Voc= 4.71V, Vmp=4.1V, Isc=0.474A, Imp= 0.456A); I've tried with different modes of the load (constant current, constant power), I've tried changing load power, changing solar array curve, and only got it into MPPT mode twice, once for each curve. I verified the outputs for the H-bridge driver en the second curve case and it was working in Boost mode. In every cases, the power at the output is way below MPP of the set curve. In both cases, when I reduced the load current below the 125mA threshold, it began the PM mode but then it didn't coma back to MPPT mode even if I increase the current again or change the input curve. Can anyone tell me what I'm doing wrong? 

I also have some questions about theoretical behavior of the SM72442:

1) The voltage set in A0 is the maximum output voltage, as it is written in the datasheet, or is it the initial output voltage set and then it can then be changed through the I2C communication, as is written in AN-2121?

2) Through pin A2, one can set the exiting panel mode power variation. Is this Input power variation or output power variation? I've tried both and my controller still in panel mode.

3) Is the start-up circuitry shown in Figure 9 of AN-2121 always required when  panel voltage is lower than output voltage? I've set my maximum output voltage (trough A0) to 55V. It was intended actually to be a maximum output voltage limitation, not a regulated voltage at the output. But if it is the set voltage at the output, maybe that is why my design is not working well, I don't have the start up circuitry.

Thank you in advance for any comment on this issue.

Hi SIr 

We used Processor-SDK-04.01.00.06 for development and used LIDD  setting to send data/command to  RA8875 chip for display.

For RA8875 , we can create framebuffer driver and can use this driver to display photo on LCD.

We would like to use QT for GUI development. Does TI have any suggestion or document how to use QT to call kernel driver to display GUI ?

or how to do connection between kernel and RA8875 driver for display?
