Part Number: MSP430I2040
Hello,
For I2C communication with MSP430i2040 EVM in previous query why user sending below string as this string is for uart with baud rate 9600? We want I2C protocol details.
byte command_frame[] = {0x68, 0x99, 0x99, 0x99, 0x99, 0x99, 0x99, 0x68, 0x23, 0x03, 0x52, 0x00, 0x00, 0xDE, 0x16};
Please share the link explaining I2C protocol for MSP430i2040.
Thanks,
Anuradha.
My customer is considering LDO.
They are looking for low fluctuate LDOs (1.8V ±5% w/ load transient).
These are conditions.
With 0A-> 250mA fluctuation, it is necessary to keep the drop within 5% from 1.8V.
Could you tell me LDO that TI recommend?

Load transient response
Iout : 0A to 250mA for 10usec (25mA/usec)
Cout : Currently 4.7uF//4.7uF are connected
Vout range : 1.8V +/-5.0%

Hi:
I am trying to use the timestamp.
Host :Ubuntu 18
1.When I try to read the timestamp by this code in my Host:
if (clock_gettime(CLOCK_REALTIME, &ts)) {
perror("clock_gettime");
}
else {
printf("clock time: %ld.%09ld or %s",
ts.tv_sec, ts.tv_nsec, ctime(&ts.tv_sec));
}It shows:
clock time: 1570078608.584780715 or Thu Oct 3 12:56:48 2019
and that is correct.
2.But when I try to use this in my Host:
#define DEVICE "/dev/ptp0"
char *device = DEVICE;
fd = open(device, O_RDWR);
if (fd < 0) {
fprintf(stderr, "opening %s: %s\n", device, strerror(errno));
return -1;
}
clkid = get_clockid(fd);
if (clock_gettime(clkid, &ts)) {
perror("clock_gettime");
}
else {
printf("clock time: %ld.%09ld or %s",
ts.tv_sec, ts.tv_nsec, ctime(&ts.tv_sec));
}It shows:
clock time: 1570107585.623349515 or Thu Oct 3 20:59:45 2019
SO what make the two results different?
--------------------------------------------------------------------------------------------------
3.Then,I try to synchronize my board
My board:AM4379
Host(ubuntu):sudo ./ptp4l -E -2 -H -i enp4s0 -l 7 -m -q -p /dev/ptp0
Slave(board):sudo ./ptp4l -E -2 -H -i eth0 -s -l 7 -m -q -p /dev/ptp0
It works!my board shows:
In my board,I use this code to read timestamp
#define DEVICE "/dev/ptp0"
char *device = DEVICE;
fd = open(device, O_RDWR);
if (fd < 0) {
fprintf(stderr, "opening %s: %s\n", device, strerror(errno));
return -1;
}
clkid = get_clockid(fd);
if (clock_gettime(clkid, &ts)) {
perror("clock_gettime");
}
else {
printf("clock time: %ld.%09ld or %s",
ts.tv_sec, ts.tv_nsec, ctime(&ts.tv_sec));
}
It shows:
the time is correct but the timestamp is not the same to my host
---------------------------------------------------------------------------------------------------------------
I want to get the timestamp in my board.the timestamp should be the same with my host(Ubuntu)
So what is the problem maybe?

Hello experts,
Part Number: LM5017
Hi E2E,
Good day. We have a customer looking for the minimum package height for the DDA (SOIC-8) package of LM5017.
Only maximum package height of 1.7mm was specified on the datasheet.
LM5017 datasheet: http://www.ti.com/lit/ds/symlink/lm5017.pdf
Thanks in advance!

Part Number: DRV5032
Hi, DRV5032 support team
Firsly, Please refer to the attached.
Customer system has 4pcs of magnet. One magnet (MG0) is to detect the open and close of board and other magnets (MG1, MG2and MG3) is to fix each boards. Hall sensor measures the magnetic flux density of MG0.
I would like to know the effect of MG1, MG2 and MG3 against hall sensor. How should I consider the effect of 3 magnets when I calculate the distance between MG0 and DRV5032? Please give me your advice.
Regards,
Tamio

Dear Experts Team,
I have been testing VIENNA Rectifier module using Code Composer Studio. And i have the following Doubts:
(1) Section 6.4.1.2 in User Guide ; Point No 3 :
I have selected Device as TMS320F28379D; But in Target Configuration it is displayed as TMS320F28377D. If i try to change and save, it is not getting changed
(2) Section 6.4.1.2 in User Guide ; Point No 4 :
When I click Run → Debug, i get an error message (Refer Attachment). Kindly provide me a solution for this issue too

Hello,
I have implemented RF network using TDMA method where all the nodes will send the data as per time allocated. But there is no event based system in it. means when nodes got the data then it cannot send the data immediately. it has to be wait until it's time comes.
so from the above i have to implement the event based network communication without changing my flow. How i can do that with TDMA method.
Please suggest any kind of solution which will work on this
Thank You

Hi support team.
Can I connet PWM-pin and SUPPLY-pin?
Jumper-5 of EVM is as follows.
"PWM is connected to SUPPLY via a resistor divider."

Hi Team,
Could you tell me how to set PWM frequency in 1XPWM mode?
Is output PWM frequency same as input PWM frequency to INHA?

Hello Sir,
I want to obtain IQ samples using rtls_aoa_iq_log.py file.
After making hardware connection when i run that python file, it is creating a .csv file of IQ samples but that is empty.
I am getting angle data on RTLS monitor.
So please tell me how to get IQ samples.
Thanks and Regards

Hello,
I have a question,
[Q]
Could you tell me how to calculate the rise and fall times of output?
Do you have information for calculating the load capacity connected to the output terminal?

Part Number: TMS320C6747
Hi,
As you see in the original post, my customer has to move over from DA810 (400Mhz version) to C6747(456Mhz version) on their custom board. My customer is asking if IBIS model of TMS320C6747DZKB4 and D810K013DZKB456 are same or not. I've already suggested the customer that should be same behavior except USB1 related pins (These devices are basically pin compatible. I mean by "basically" that C6747 has USB1, but DA810 does not). Is that correct, right? It seems my customer would like to know TI's comment rather than mine.

Hi
I migrated project from CCS5 to CCS9 and compared the .map files generated by different CCS using the same source code.
I noticed optimization in memory usage but some symbols(functions) which exist in CCS5 map file but not in CCS9 map file. About 100 out of 1100 symbols are missing
I did confirm that the functions exist in the source code.
Can anyone help? Is this issue related to some project settings?
Thank you

Part Number: TM4C1294KCPDT
Hello Everyone,
I am using tiva tm4c1294kcpdt. In my application, i have multiple tasks on ethernet interface: logging data to server, telnet server for debugging, ftpd server to access memory card , etc.
If I try to handle all tasks at a same time then device will either goes into fault isr or gives me watchdog interrupt.
I am calling lwIPTimer() in 10msec systick isr, and all these tasks are written in while(1) loop.
Can any one suggest me how to handle lwip / ethernet isr systematically?
Any help would be appreciated.

Dear Sir / Madam
Very Good Morning
I have few queries related to DAC. I have generated sinusoidal signal using trigonometric function in CCS V9 and I wanted to see the generated waveform in digital storage oscilloscope (DSO). I have tried to configure the DAC but it is not properly working. The waveform captured in the DSO is not the expected one.
Therefore, please provide me information related to DAC configuration and what is the correct procedure to observe the waveform in DSO using DAC.
