CCS/CC2642R: Lowering the power consumption of Project Zero example

$
0
0

Part Number: CC2642R

Tool/software: Code Composer Studio

Hello,

I'm trying to get a handle on using the CC2642 and I'm trying to setup a sample project that is showing off the low power nature of this microcontroller (I'd like to show something that is showing less than 1mW of power consumption with sparse Bluetooth messages).

I'm starting from the Project Zero example, but I'm having trouble getting it to be low power, and I'm wondering if maybe it's not entering sleep mode?

Here are my results for power consumption measured using the EnergyTrace feature in Code Composer (I'm using this with a CC26x2 LaunchPad (which actually has a CC2652 rev E on board):

With the Project Zero example unaltered, the power during advertising is ~2.7mW and the power during a connection with a phone is ~3.5mW.

To reduce I went into the syscfg file and changed the Tx power from 5dBm to 0dBm. However, the power consumption remained exactly the same.

I then changed the min and max connection interval from 15ms and 45ms to 800ms and 1000ms.

This slightly reduced the power consumption during the connected state from 3.5mW to 3.2mW, but this is still a huge amount of power for such a low connection interval.

Is there something else I should be doing to reduce the power? I was able to get lower power numbers using the very old CC2540, so I'm certain that I'm not doing something correctly.

Any help would be much appreciated!


AFE4490: ATE4490 SPI does not read

Part Number: AFE4490

Hi guys, I am trying to read some registers from ATE4490 using NXP iMX RT1064 MCU. Please see the attached wave forms where you can see the clock in blue and MOSI signals in yellow. I am initially send this 4 byte to CONTROL0: uint8_t CONTROL0ReadBuffer[4]={0x00,0x00,0x00,0x0F}; right after I am sending other 4 bytes to read LED2VAL: buffer[4]={0x2A,0x00,0x00,0x00};

Could you please double check for me what am I missing my configuration. May SPI baudrate is around 100KHz; and I also verified that the reset pin( pin 20) and power down pi(pin 29) are pulled up high.

Hi

Is there any sample code for VIP on RTOS SDK?

I cannot find it.

(Unfortunately, I can find the following note on software-dl.ti.com/.../index_device_drv.html

   "The camera driver support is not added for evmAM572x boards (GP AM572x EVM) - and hence all the tests related to camera are skipped for evmAM572x board.")

Thanks and Best regards,

HaTa.

ADS112C04: Error on ADS 112C04 check value

Part Number: ADS112C04

Hello, everyone!

This is Linmaoxin of Shanghai Baolong Automobile Technology Co. Ltd.. I have one problems here that I need TI to help solve.


1. Regarding the integrity check of ads112c04 chip sampling data, when I opened the CRC16-CCITT check, I found that the conversion data did not match the self-calculated checksum.

When the data was demodulated, it was found that the MSB(high) bit was always 0X95, and the LSB(low) bit data was correct. Columns such as: data 0x95, 0x2f check value 0x31, 0x91

(IIC data reading is normal, read and write registers are normal, hardware is normal).I don't know what caused the problem.

 

              The following is the register configuration and registration address:

                 const ADS112RegisterTable_t ADS112RegisterTable[4] = 
                 {
                          0x00, 0x36,
                          0x04, 0xA0,
                          0x08, 0x25,              

                          0x0C, 0xA0,                        

                };

hi expert,

I have a customer wants to use Ethercat on F28388D, and I pre-study on the demo provided in this path:

C:\ti\c2000\C2000Ware_MotorControl_SDK_2_00_00_00\solutions\tmdxiddk379d\f2838x

after demoing this, I am wandering how much loading Ethercat occupys the ARM4 core, which I want to know besides ethercat, what can I do using ARM4 at the same time?

Awile ago I witnessed what appeared to be a Texas Instruments Radar Tube Socket Enclosure. The enlosure was Aluminum, had tube sockets on the top of the chassis, and beared the Texas Instruments logo on the front of it. Can't find any information anywhere on this. I trying to prototype my own rendition here

Any information some baby boomer can provide would be helpful.

Thank,

Part Number: LMR14030

Hi team,

customer test LMR14030 over current protection. customer applicaiton are that:

input 24V ; output 5V

test condition is connect 5V to ground, power up 24V,  they found that the tempature of LMR14030 will be very high, can reach up to about 100C. also, the tempature of inductior and diode will up to 168C.

could you give suggestions about why the LMR14030 tempature very high, does this the normal? what's the over current protection conditions?

thank you.

Hello Experts,

I have a question as attached file. Would you answer it, please?The main topology can work normally with
load, but the parallel current sharing is very unstable. Is there any problem with the circuit of
accessories? Is there any effect on current sharing if the primary and secondary sides are not isolated?
In addition, whether it can provide some low side high voltage application circuit reference

LMR23610: which product will be working without soldering on thermal pad?

$

Part Number: LMR23610

Hi, Team.

could you tell me what suitable product is?

Vin:36V

Vout:24V

Iout:3A

note

customer doesn't want to use thermal pad.

so they don't solder on thermal pad so it would be floating.

if the product relies on thermal pad as GND, the product wouldn't be accepted in this case.

(I have promoted LMR33630 but it must have "soldering" on thermal PAD so the product can't work properly.)

Hi All,

I use DS90UB954-Q1EVM Quick Start demo circuit to change ds90ub962-q1 chip to support  ds90ub953-q1 mipi output.

But, we find ds90ub962-q1 don't  compatible with  ds90ub953-q1. There will be link loss when 962 connect to 953, and will be link good when link with 933.

TMDSECATCNCD379D: Trim Down Delay Within SPI Read/Write Function

$
0
0

Part Number: TMDSECATCNCD379D

Hi there,

We are working with the EtherCAT slave stack code and trying trim down SPI and Sync0 ISR run time. Digging a little deeper we found that SPI read/write (etherCAT_slave_c28x_hal.c ESC_readSPI and ESC_writeSPI) takes up a lot of time. E.g. in ESC_readSPI there are 3 delays, 10, 5 and 2us. 

My question can I cut back these delay? Will there be any adverse effect? (like maybe mixed up bit, incomplete read/write?)

Thanks for reading, any reply is greatly appreciate.
