Part Number:SN65HVD1781A-Q1
Hello,
I am looking into Automotive grade RS485 Transceiver. So Came across SN65HVD1781A-Q1 and SN65HVD1781-Q1. Can you please tell me the difference between the two parts. I have check the comparison between both. Everything is almost same except the price. I am attaching the comparison table in this post for your continence.
Note : I have check the signaling rate for the SN65HVD1781A-Q1 which is also same as SN65HVD1781-Q1.
Thanks,

Part Number:SN75LVCP600S
Hi team,
My customer would like to use a SN75LVCP600S in his project,
According to the datasheet this device allows a hot-plug feature.
Does it mean he can remove the SSD while transfering data?
If so, what is the difference between this item and eSATA?
Thanks in advance.
Kind regards,
Shai
Part Number:INA180
Hi all.
I have ordered samples of the INA180A2IDBVT current sense amplifier. It's the 5-pin sot23 package. On page 3 of the datasheet it shows that it has 2 different pinouts , A and B.
How do I know what pinout's my version has. I can't find anything in the datasheet that shows any difference in the part numbering?
Cheers
Rob

Hai all,
I am using the CCS V6 and the TMS570ls3137 , How can I generate .bin file from the CCS?
Could you please help us to resolve this issue.

Hello,
I'd like to know what's the maximum nominal load current with this quad-channel switch please.
In the datasheet, it is written 2,5A in RECOMMENDED OPERTAING CONDITIONS, but I'd like to be sure this value stands for "per channel".
Thank you,
Best regards

Part Number:TMS570LS0714
Hi,
we use a TMS570LS0714 and have implemented the diagnostic test for the Flash in our application firmware.
Periodically we run this tests with test type FLASH_ECC_TEST_MODE_2BIT but the firmware hang after the instruction:
flashread = *(volatile uint32 *)flashBadECC2; (line 1280 of sl_selftest.c version 2.4.0)
How can we manage it?
NOTE: In the first part of the flash (from 0 to 0x0020000) we have made a custom bootloader version with ECC disabled. It could be a problem?
Thank you.

Hello,
Referring to my previous post 
While going through tda2p-evm user guide, I found that "UART3 peripheral boot and terminal access requires a on-board resistor modification".
The reference of the same is attached. So please suggest do we need to do this resistor modification in our case for UART (mflash) boot.

Part Number:TPS2511
Hi Team,
My customers do not pass BC 1.2 (DCP only) compliance test.
Please give me advice to pass.
<BC 1.2 compliance test items and results in DCP mode>
・DCP Overshoot and Undershoot Voltage Test ：PASS
・DCP Voltage and Current Test ：PASS
・DCP - Handshaking Test ：FAIL
Check D- voltage is in range VDM_SRC (0.5V - 0.7V). [DCP12, DCP13]
ERRO: D- voltage was not in range VDM_SRC (0.5V - 0.7V), D- = 772 mV.
・DCP Resistance and Capacitance Tests ：FAIL
Measure voltages at D+ and D-. The difference must be less than 0.67V.
INFO: D- = 63 mV
INFO: D+ = 1489 mV
ERRO: D+ and D- difference was not less than 0.67V, Vdp - Vdm = 1426 mV
Please contact me if you need additional data.
Also, please let me know about recommended test equipment, test environment information.
Best Regards,

Please help me on how to use roundf function which are available in math.h.
roundf function is working outside CLA.
When used within CLA, I'm getting implicitly declared warning.
Part Number:TMS320F28335
Tool/software: Code Composer Studio
I'm trying to calculate speed from the position encoder mounted on my PMSM. I'm successfully able to get the position(in degrees). I tried to do speed = (new_position - old_position)/delta_t but i'm plotting the result in DAC, I'm getting random large peaks in between. I'm not able to figure out what the problem is.
P.S. I'm getting position after every 400us(synced with PWM ISR) but the speed function is executed only in intervals of 10ms.
Part Number:TMS320F28335
Tool/software: Code Composer Studio
There is two project in F28335, one is bootloader and another one is App. When power on, first bootloader will run code from default code_start address(0x33FFF6). Then branch to App project code_start address(0x300008). Both code_start is as following(i.e. DSP2833x_CodeStartBranch.asm) and the watchdog is disabled.
code_start: .if WD_DISABLE == 1 LB wd_disable ;Branch to watchdog disable code .else LB _c_int00 ;Branch to start of boot.asm in RTS library .endif
;end codestart section
I add code in App project to check watchdog WDFLAG bit as following(follow the errata document to resolve XINTF module bug)
EALLOW;
if((SysCtrlRegs.WDCR & 0x0080) == 0)
{
SysCtrlRegs.WDCR = 0x0028;
SysCtrlRegs.WDKEY = 0x0055;
SysCtrlRegs.WDKEY = 0x00AA;
}
else
{
SysCtrlRegs.WDCR |= 0x0080;
}
EDIS;
However, after the watchdog reset, the code "SysCtrlRegs.WDCR |= 0x0080" seems cannot disable watchdog. However, code_start should have disabled the watchdog. How to understand this problem? What the differene related with code_start between power on and watchdog reset? thanks.
Part Number:MSP430F2112
Hello,
Despite the following description, my customers mention that incorrect password erases Information Memory.
"When an incorrect password is given, a mass erase is initiated. This means all code flash is erased, but not Information Memory."
The description is in chapter 3.5.2 of the following document.
www.ti.com/.../slau319r.pdf
My customers use MSP430F2112.
In case of MSP430F2112, is Information Memory erased by the incorrect password?

Part Number:SENSOR-CONTROLLER-STUDIO
Hello,
I'm working on multirole project on stack simplelink_cc2640r2_sdk_1_40_00_45, XDC tools 3.50.4.43 and cc2640r2f custom made sensortag devices.
I want to use sensor controller studio to program my sensors and merge this with multirole project is it possible.
As I'm new to sensor controller studio, can anybody suggest what all things need to be done.
Part Number:LAUNCHXL-CC2640R2
Tool/software:TI-RTOS
I Have developed my Firmware taking Project Zero as reference,
And i have changed the name of the code (i.e., for both app and stack file ) and all things are working fine not any issue,
However When i export the code (i.e., Both app and stack file) and try to import the code in any other work space it gives an error that Project_zero_stack file missing,
Though the same Project_zero_Stack file is alerady imported and are present in the work space but with changed name, I think even after changing both code name app and stack the app file is using Project Zero Stack
So how an resolve this issue as when i such change the name of the app and stack the stack still is linking with project zero
Please help me with this.
Thanks and Regards

Part Number:AMC1210
Hi Tom,
I am using SPI interface to read AMS1210. However I am getting fluctuating data register values for fixed DC voltage input given at AMC1204 input.
The configuration registers programmed are as follows.
Control Parameter : 0x0010
Sinc filter: 0x0F1F
Intergrator Parameter: 0x0000
High Level Threshold: 0x7FFF (default)
Low Level Threshold: 0x0000(default)
Comparator : 0x0000 (default)
Control Register: 0x2000
Clock Divider: 0x0810
I have tried by making integrator ON, however there is no effect.
What can be the reason for the fluctuation? How to make the data stable?

Part Number:RM57L843
Hi,
I wirte to the DPRAM data with this simple code:
unsigned int Ext_Async_Mem_Write2(unsigned int Ext_Mem_Address_Ptr, unsigned int Data_To_Write_Ptr, unsigned int No_Of_32BitData)
{
unsigned short *Addr = (unsigned short *) Ext_Mem_Address_Ptr;
while(No_Of_32BitData > 0)
{
*Addr++ = Data_To_Write_Ptr++;
No_Of_32BitData--;
}
return 0;
}
On the digital analyser I see only the addresses 001, 003, 005 but the data is in the right order, check the pic attached. I don't unterstand why?
Part Number:AM3359
Hi
I understand the AM3359 datasheet section 7.7.2.3 covers the routing guidelines for DDR3 placement, length, spacing between nets etc..
Is there any guideline / recommendation available for Serpentine / Meandering Routing for DDR3 signals? what will be the appropriate space between the serpentine loops that are in parallel (same net)?
Regards
