TPS2540: D+/D- pass-through for OTG dual role devices

October 16, 2019, 3:00 am
$

0

Part Number: TPS2540

The TPS2540 datasheet shows a "Host Sense" block in the diagram on page 9, but doesn't describe its function.  If the TPS2540 detects the DM_OUT and DP_OUT pins are in a device mode state, will it simply turn on the data switches from in to out?

If not, is there another way to get the TPS2540 to pass through the D+ and D- signals, but not pass power from the OUT pin?  Or is there another product that behaves as a USB charge port power switch controller for a OTG device in host mode, but a signal pass-through when in device mode?

Part Number: EVMK2H

Hi,

I need to write a kernel module for PCI and then cross compile it using ti-evmk2h-processor-sdk-5.02.00.10. How do i have to set up the make file, i tried one with the following

obj-m := pci_mod_PBv7.o

KDIR := /home/sheraz/ti-processor-sdk-linux-k2hk-evm-05.02.00.10/board-support/linux-4.14.79+gitAUTOINC+bde58ab01e-gbde58ab01e
#CCFLAGS:= -O0#yaseen add to force no optimization

ARCH=arm
CROSS_COMPILE=arm-linux-gnueabihf-


PWD := $(shell pwd)
default:
$(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules

 but when i make i get the following

make[1]: Entering directory '/home/sheraz/ti-processor-sdk-linux-k2hk-evm-05.02.00.10/board-support/linux-4.14.79+gitAUTOINC+bde58ab01e-gbde58ab01e'

LAUNCHXL-CC1352P: need FATFS on support on the cc1352 for extflash

October 16, 2019, 4:00 am

Part Number: LAUNCHXL-CC1352P

As I read in the related thread it seems possible to port the FATSD example from the cc32xx to the cc1352.

As we need filesystem support on our device I wanted to try this out but instead of an SD card we just want to use the external flash (which then in the end will be a bigger variant then the one on the launchpad).

In the board file from the launchpad there is already a setup for SD card with CC1352P1_LAUNCHXL_SDCOUNT=1

This puzzles me a bit because the launchpad has no SD card.

How can I use the FAT filesystem with the external flash already on the launchpad?

Part Number: THS6222

The signal generator is used to input 100mV1MHz ac signal, and the observed signal with oscilloscope is vp-p =280mV 1MHz.

The input signal is amplified 10 times by the THS6222RHF Evaluation  Module. The output signal with oscilloscope is used to output vp-p1v 1MHz signal.Why not Vp-p=2.8V1MHz?

Part Number: SN65DP159

Dear all,

I would like to ask 2 questions about operation timing.

The contents written as meaning at td1 in the table below are “VDD / VCC stable before VCC / VDD”.

What does "stable" as used here mean in the state of VCC or VDD?

(For example, when the voltage has risen to 90% of VCC or VDD, or when VCC or VDD has risen and stabilized)

Also, in the above table, can td1 and VDD_ramp (VCC_ramp) parameters be considered to indicate the part in the figure below?

Best Regards,

Y.Ottey

PROCESSOR-SDK-AM57X: Context switch latency

Part Number: PROCESSOR-SDK-AM57X

Hello,

Software: PROCESSOR-SDK-LINUX-RT-AM57X V04.03

Hardware: AM574X-IDK

I m measuring the overhead of context switch by lat_ctx which is mentioned on this page. The result show that it spends around 10~15us on context switch each time which is more than I expected. Is the number reasonable? If it is, do we have any ways to optimize the overhead? Like increasing CPU clock, or upgrade Linux version? Thanks for any comment.

TAS2559: TAS2559 setting question

Part Number: TAS2559

Hi all,

 We want to test TAS2559EVM with external I2S source. Here're some questions:

1. In ROM-Mode 1, is TAS2559 worked as I2S master mode? can we change the setting to slave mode by I2C register rewrite? How to do it?

2. For 48KHz/I2S input/ 16bit data length source from ASI1 input, would you please helping to provide a sample cfg for reference first? We'll use learning board to fine tune the speaker in the next step. Or, I can use learning board to build up a simple cfg first?

 Thanks for your kindly help.

Best regards,

Gary Teng

BTW, I dump ROM-mode 1 register setting as cfg file. FYI. It's master mode now...

CCS/CC3200: Is there a WIFI AP status monitoring API in the CC3200 SDK?

Part Number: CC3200

Tool/software: Code Composer Studio

When using the Apple mobile phone to connect to the WIFI hotspot of the CC3200, there is a certain probability that the WIFI hotspot will disappear. At this time, the computer or mobile phone cannot scan the hotspot again, but the module can work normally, waiting for 20-30 seconds later. This WIFI hotspot has returned to normal; does the SDK have an API interface that can determine whether the AP status is normal, so it is convenient to check the interface periodically, and if it is abnormal, it can be processed in time; look forward to reply as soon as possible, thank you for your support.
