We are using BLE IC CC2642R, wi-fi controller CC3220S and temperature sensor HDC2080 in our project. We are doing DC and AC analysis before schematic design. Below information is missing in their datasheets:
CC3220S
DC Analysis
CC3220
VOH (Min) V ?
VOL (Max) V ?
And for AC analysis, we need timing analysis for I2C interface for CC3220S.
The considered design has the controller feeding I2C configuration, Reset control and I2S on an independant board with dedicated powzer supplies. To the TAS3251 may be powzered ON qnd OFF independantly of the controller board.
Reading the datasheet, I did nout found reasons for this configuration not to work, especially if there is a pull down on the Reset_Amp pin and and a supply voltage supervisor to control that same pin (as on the TAS3251EVM).
1) Would you confirm the above?
2) Any additional advice to avoid pops for the Power OFF sequence, to complement the supply voltage supervisor ?
3) Is there an advised minimum delay for the supply voltage supervisor (didn't found any in the datasheet)? Would 200ms be OK ?
4) From the datasheet, I considered that 100 mA was the maximum needed for the 15V part of the power scheme (then delivering the 12V and 3.3V subsections) Is this correct ?
In our application, we need to wake-up the MCU when there is a signal on pin P1.1 & then measure the voltage present on the same pin.
For this, we have followed below approach.
configure Pin P1.1 as digital i/p pin - enable interrupt for the same - go to sleep mode (LPM0)
upon wake-up, by interrupt on P1.1, reconfigure this pin as analog i/p channel A1
calculate voltage on P1.1 using ADC & do other tasks
Go to Point - 1
But, it doesn't work. MCU wakes-up & performs the voltage calculation task, when interrupted on the pin P1.1 for the first time only. After that, MCU doesn't generate interrupt on pin P1.1.
Can anyone help us to resolve this issue? If there is an alternate approach to fulfill our application requirement, please share it with us.
We were reading the 'TIDL: Trouble-Shooting Guide' in the documentation provided for TIDL Import tool tidl_j7_01_00_00_00. Under the title 'Steps to Debug Functional Mismatch', it refers to a document named '!tidl_fsg_quantization.md::did_tidl_quantization_Types'. The file is not a hyperlink and we are not able to locate the file in release.
Could you please guide us on how to locate this file?
I'm working on rfEasyLink project. I want to send a sensor data periodically every 10seconds. For that I'm using the Clock_Construct api from utility.c file. But even after including the file header and giving path of the same, im getting the following error while linking. please let me know how can I solve the issue. I'm new to CCS compiler.
error #10234-D: unresolved symbols remain error #10010: errors encountered during linking; "test1.out" not built gmake: *** [test1.out] Error 1 gmake: Target `all' not remade because of errors.
Our customers would like to know the battery lifetime of the coin cell battery if all the sensors are active all the time using the zigbee or 6lowpan network for the CC2650STK.
Are (BQ25892)charger and fuel gauge (BQ28Z610) compatible? During Gauge BQ28Z610 broadcasting desired current and voltage target values through I2C, can BQ25892 receive these values to drive VBAT ( Battery Pack Voltage ) ?
DRV10987 empty stata start motor and enter closed mode speed 100hz current 0.37A, then change the load speed 100hz current clamb until 0.76 A then gui show overcurrent and motor stoped . why current cannot continue clamb to max 2A？
DATEsheet show the DRV10987 rated current 2A ,and MY MOTOR rated current 1.8A.
I want to realize cia402 on AM3359.I have generated the ethercat_slave_full project and redfined the "ecat_def.h".The project ran well on AM3359ICE board.But why the program displayed on TwinCAT is the program of AM437x.It shows TIESC_CiA-002.The xml file said TIESC_CiA-002 should run on AM437x.TIESC_CiA-001 is used AM3359.Even if I chenged all the "ProductCode" to"54490001",it still does not work.There are a few pictures and the "ecat_def.h".
I am a freshman in this field.The whole project is hard for me is there any article to help me understand the whole project,It is best to have the running process on TI RTOS.
I have seen MSP430F6779A's data sheet (SLAS982A) and also see "Using power solutions to extend battery life in MSP430™ MCU applications" (SLYT356A). From my point of view all of recommend supply currents in MSP430F6779A's data sheet might be increase in linearly as well as below figure from SLYT356A. Am I right?
Because I have problem about finding current consumption of MCU when it is supplied with 3.3 V of power supply. But entirely data sheet is specified in range of 3.0 V as below figure is from Active mode supply current in MSP430F6779A's data sheet.
We connected the EVM input to a DC Power Supply. EVM Output is not connected to any load. As soon we apply input from 0V and gradually increase towards 1V, the input current drawn shoots up suddenly, towards 2A. We switched off the input instantaneously at this point of time, foreseeing any damage to the EVM. We repeated this and got the same result, means no additional damage occurred to the EVM due to our powering up exercise. We did not try with POE PSE, in order to avoid possible damage to the EVM.
But they want to build a 8k monitor. Is HD3SS215RTQR able to support this function?
As I check the HDMI data rate. For 8k application, the data rate is up to 16 Gbps(HDMI2.1). HD3SS215 is only able to support HDMI 2.0(6.0 Gbps) is that correct? Do we have any suitable device?
