EVM430-FR6047: need help on finding a variable to monitor Delta time of flight value without launching the GUI

yes, that is working, some how i wanted to show value in code by putting the break point. pls help.
USS_Algorithms_Results_fixed_point algResFixed; tried monitoring values of structure, value gets updated only when a request from GUI. but i want to avoid GUI.

we have built a custom board using 6043 and it does not have LCD, i wanted to verify the DTOF values by putting the break point the code. 

Hi,

You can add the break point right after calling USS_runAlgorithmsFixedPoint(). The dTOF value will be updated in algResFixed.

yes, i am able to observe the values which is not same as values on GUI, i need float values pelase.

    if(true == DC_User_Params->appReqData) where to set this parameter to TRUE, then i can view the values, please guide.

in hmi.c, i i can read float values only DC_User_Params->appReqData is set to true, it will set to true only when a request comes from GUI. how to read float values without a GUI.

Dear Cash Hao, 

1. need help on how to route measurement values over UART and observing values over GUI.
2. DC_User_Params->appReqData how to set to true without initiating the GUI

Thank you.

out of my learning, where to set parameter to ture. kindly guide me.

Hi,

Well, I do not have much experience on where to set it. But I think you can just directly set DC_User_Params->appReqData to true in the main loop of the code.

i tried it , its not working. 
we are building water meter using MSP430FR6403 and i found that ReVA chip has some issues with respect to the below. 

The MSP430FR6043 Rev A microcontroller, particularly when used for ultrasonic sensing applications, can have some known issues. These include challenges with ADC waveform capture, potential cycle slip issues affecting time-of-flight (ToF) and velocity flow rate (VFR) readings, and the need for careful system and clock configuration. 

due to recommend to use revB chip ? if yes, how to order it asking RevB specifically

Hi,

There are only Rev A version and early sample with X marked for FR6043. There is no Rev B version device. 

Best regards,

Cash Hao

if i understood correctly, there is no RevB version available in the market. latest version is RevA and there is no errata right, we can use it for water meter solution . 

Dear Cash Hao,

could you please help me to understand the interfacing the LCD on EVM KIt. any reference datasheet of LCD about interfacing. 

Thank you.

I can only find this one for the LCD.

/cfs-file/__key/communityserver-discussions-components-files/166/FH1138P-REV-1_2800_N_2900_.pdf

need help in interfacing this LCD with MSP430FR6043. 

Hi,

What do you mean by interfacing with LCD. Do you need to know how it operates? Then you can check the files in project->USSLibGUIApp->fr6043_USS_app->lcd_statemachineDC for the details about how the LCD stat machine runs. 

Best regards,

Cash Hao

i wanted to understand how LCD can be interfaced programmatically and enabling each segments. 

Hi,

You can also check the code in hal_lcd.c. It contains how to interface with LCD by coding. It is in project->hal->fr6043EVM->hal_lcd.c

Best regards,

Cash Hao

is there any document or reference is available to understand how to turn on each segment / symbol / displaying digits it's respective positions.

The muxRate is how many MUX is required in your design. There is a basic introduction of LCD driver in this app note. You can check with it first. https://www.ti.com/lit/an/slaa654a/slaa654a.pdf

Thank you let me go through it.
is it required to connect exact LCD pin number ordering to MCUs pins. exp LCD pint to be connected to LCSD1 , LCD Com0 pin to COM0 of MCUs only.

It is not strictly required to match them. But I would recommend to do that since it can keep the same definition on both sides, otherwise it could be confusing somehow.

can i connect Com1 of LCD to LCDS1 pin of MCU ? if i connect like this, do i need to change the driver code? 

is it required to connect COM pins of LCD to COM pins of MCU ?

can i connect LCD pin 1 to P1.0 which is a normal GPIO ? pls suggest .  

kindly verify the below LCD pin mapping to MCU. please help.

MCU pin : 53 (MSP430fr6043) has P6.5/COM1/LCDS34. so, if i need COM1 and LSDS34 to be connected to custom LCD, how can i use its functionality.

Thank you so much for you help and support. great help.
