TSC2013-Q1: TSC2013-Q1 dual touch details confirmation

$

0

Part Number: TSC2013-Q1

Hi Team,

My customer would like to confirm if TSC2013-Q1 could support common dual touch function like below. We checked the link but found the dual touch zoom in/out seems not doable by using TSC2013-Q1? Please help to double confirm.

Also, please help to confirm and share the Linux drive again which was listed in the discussion but the link is not valid now.

earlier discussion here:

https://e2e.ti.com/support/data-converters/f/73/t/426404?tisearch=e2e-sitesearch&keymatch=TSC2013%20DUAL

"No, we don't have the reference Windows driver for TSC2013-Q1 now.  Instead, there is a reference Linux driver available.

Here is its link e2e.ti.com/.../3151.reference-linux-driver-for-tsc2013-q1"

 


LAUNCHXL-CC26X2R1: JesFs V1.5 updated

Part Number: LAUNCHXL-CC26X2R1

Hi community,

Starting with a new product on the CC13xx / CC26xx, I was playing with the Serial Flash of the Launchpad.

I have been using similar Serial Flash on this and other platforms to implement a very robust File System for data files and firmware files.
JesFs was designed as an ultra robust File System for Embedded System and I use it for my own daily work (which is ultra low poer scientific data loggers).

Well, here we are in V1.5: https://github.com/joembedded/JesFs 

JesFs is is licensed under LGPL 3.0 and hence anyone can use it for free.

Cheers,

Compiler/TMS320F28335: The problem of changing from interrupt mode to non-interrupted transmission and reception mode

$
0
0

Part Number: TMS320F28335

Tool/software: TI C/C++ Compiler

Hi Sir,

The DSCs has a serial port because the peripheral needs to change from interrupt mode to non-interruptive transmission and reception mode. There is no use of FIFO. The data sent out is available.

The received data can also be observed with an oscilloscope. The "RX" mark cannot be read! Not sure what the problem is and would like to ask for suggestions.

*Schematic: Color is the motherboard side, black & white is the communication board side, WK2132 is a serial port 1 to 2 device.

*Waveform: Blue is sending 0x40, yellow is receiving 0xf0.

Initialization code:

---------------------------------------------------------------------------------------------

void scib_init(void)

{

   /*����B����*/

   ScibRegs.SCICCR.all =0x0007;   // 1 stop bit, No loopback

                                   // No parity,8 char bits,

                                   // async mode, idle-line protocol

   ScibRegs.SCICTL1.all =0x0003; // enable TX, RX, internal SCICLK,

                                   // Disable RX ERR, SLEEP, TXWAKE

   ScibRegs.SCICTL2.bit.RXBKINTENA = 0;     //�����ж�ʹ��

   ScibRegs.SCICTL2.bit.TXINTENA = 0;     //�����жϲ�ʹ��

 

   ScibRegs.SCIHBAUD   =0x0000;

   //ScibRegs.SCILBAUD   =0x0028;// 115200 baud @LSPCLK = 37.5MHz.

   ScibRegs.SCILBAUD   =0x0051;// 57600 baud @LSPCLK = 37.5MHz.

 

       ScibRegs.SCIFFTX.all = 0x0000;

       ScibRegs.SCIFFRX.all = 0x0000;

 

ScibRegs.SCIFFCT.all = 0x00;

   ScibRegs.SCIFFTX.bit.TXFFINTCLR = 0;

 

   ScibRegs.SCICTL1.all =0x0023; // Relinquish SCI from Reset

  

}

 

void scib_xmit(int a)

{

   while (ScibRegs.SCICTL2.bit.TXRDY == 0) {};

   ScibRegs.SCITXBUF = a;

}

 

int scib_receiv(void)

{

   while (ScibRegs.SCIRXST.bit.RXRDY == 0) {};

   return ScibRegs.SCIRXBUF.bit.RXDT;

}

AM5728: Is it feasible to implement the machine vision and motion control based on the AM5728?

$

Part Number: AM5728

Now, our company use the AM5728 of TI, mainly machine vision, but we want to implement the function of motion control
and machine vision based on this platform. it is hoped that the engineers of TI can help to evaluate the project
plan and technical support: Is it feasible to implement the machine vision and motion control based on the AM5728?
When the AM5728 is used to realize the motion control, it is difficult to control the synchronous design of the
multi-axis motor. If AM5728 is not supported, can you recommend some other options? Thank you!

BQ24610: BQ24610: Problems about temperature

$

Part Number: BQ24610

Hi,

The schematic diagram of the circuit being debugged is as follows.

The relevant parameters are as follows.

(1) Input voltage : 24V;

(2) Battery charge voltage : 12.6V;

(3) Battery charge current : 2.8A;

(4)Precharge and termination current : 0.3A;

(5)Safety timer: 9.3h (CTTC-0.1uF);

Charging function is normal, but the chip bq24610 temperature is very high. The surface temperature of the inductor is also very high. Heat sink pad is connected to GND, and copper coating area is also large.

Please help to analyze the possible reasons.

p.s. Input voltage is 15V, the temperature is not high.

CC3220SF: Cannot open source file

Part Number: CC3220SF

Hello,

I am trying to port tcpHandler function from tcpecho example to cloud_ota project. 

while compiling after porting the function to cloud_ota project compiler returns an error

#1965 cannot open source file "netinet/in.h" 

same goes with other BSD support files

/* BSD support */
#include <netinet/in.h>
#include <arpa/inet.h>
#include <sys/socket.h>

I don't understand why including header files get compiled in one project and cannot in another project.

Can someone please help me resolve this issue.

Thank you,

Kris.

Dears

when customer test the TPS65150 VGH, they find there have many voltage step on the output, like the soft start, but this phenomenon not mentioned in the datasheet, would like to check if this is ok or there have some design issue. thanks

Part Number: LMK04806

Dear team,

Customer find some test result unmatch with datasheet. For example, customer config as description marked yellow as below picture shows. But the test result shows only CLKINX_SE_MODE=1 the clock could lock, which is different with the description.

Could you help clarify this? Or do we have new LMK04806 material?

Thanks.

Part Number: DRV10983-Q1

Hello i am engineer in amotech. co

I am making 3 phase motor for my customer.(massive product date will be on 2021-1-15)

My customer said that they can send my motor maximum 90% PWM Duty. but they requst 3000rpm motor speed.

but my motor only rotate 3000rpm by using 99% pwm duty.(i change parameter value a lot. i cant find proper value. i thought it is not possible to meet customer request by turning drive ic)

So I want to know the way to make my motor ratate 3000rpm by using 90 pwm duty( or let me know whether it is possible or not)

I hope receive your answer as soon as possible.

Thank you.

IWR6843ISK: IWR6843 static clutter removal

$

Part Number: IWR6843ISK

In IWR6843, TI provides the capability of static clutter removal. I have some question on this feature.

1. Is there a way to disable such a feature? If so, how can I disable it?

2. If it is enable, does it mean all the static targets would be filtered filtered out? In other words, do you separate static target from static clutter?

3. As a user, can I specify a threshold value so that only those static clutters whose SNR is below this threshold would be removed?

Thanks!

Part Number: TMS320C28345

Tool/software: Code Composer Studio

I download my out file from JTAG and it runs very well. However I download it from SCI by boot rom it goes into illegal ISR and reset repeatly.

The same out file produces the different result. Is there any differences between the two operations?

who can tell me the reason?

Wait for the reply eagerly!

THANK YOU!
