    CC3200 transceiver mode in energia.

    in Energia - TivaC/CC3XXX

    Posted

    Hello,.

    My idea is about connecting two CC3200 without a separate WiFi router like with their own like for example share it app which connects two devices using wifi one device with hotspot and one connected to that hotspot and share data.
    Is it possible to do that? As my idea is to share short text data between devices. using energia

    I want to continuously  send/receive data between 2 cc3200 without any other modem unit or with another cc3200 which will be an access point between 2 of them. Is this possible ? If so , where should i begin?

    cc3200 (unit a) <-------> cc3200 (unit b)             or         cc3200 (unit a)  <------via cc3200 (as AP) -------> cc3200 (unit b)

    Thank you

    Use of UART on pin numbers 3 and 4 on cc3200.

    Hello there,

    Ive been trying to use the UART on pin number 3 and 4 by using serial for monitoring the received data and serial1 for connecting and controlling the hardware(GPS) but the by  using serial1 i think  the uart isnt active.

    i see by connecting gps to putty that there is no data sent from the cc device .

    I checked the hardware serial .h and .cpp file where in the cpp file there is serial1 functions mentioned but in the pins_energia file i see no pin initialized as uart only analog, timers and gpio's are initialized. So what can i do to make it work.

    Serial1.begin(112500);
    Serial.begin(19200);
    delay(50);
    Serial1.println("AT");
    delay(1000);
    Serial1.println("AT+QGNSSC?");
    delay(1000);
     
    Serial1.println("AT+QGNSSC=1");
    delay(1000);
     
    Serial1.println("AT+QGNSSTS?");
    delay(1000);

    Splitting a string of data in Energia.

    in Energia - MSP

    Hello there,

    I connected a gps module and it gives me the gps data but im unable to segregate the following data on energia

    +QGNSSRD: $GNRMC,044927.000,A,1301.7816,N,07731.3016,E,0.00,93.73,290319,,,A*4F

    so i need to separate the latitude and longitude, time and date.

    So can anybody help me in understanding how to get the required data from the above.

    i attached my code below as you can see im getting stuck in the serial read please help me in correcting this.

    ?

    Hercules support in Energia?

    Hercules is a great processor but it is also a bit to niche for Energia. With that said, if there is growing demand for it I might consider adding support for it in the future.

     

    What would your application be if we would have Energia support for it?

    Hi,

    When is the support for hercules launchpad is added?

    MSP430FR6989 pins_energia file

    in Energia - MSP

    Posted

    Hi there,

    I've seen that the pins_energia file for MSP430FR6989 is designed for launchpad itself. So i,m developing a custom board using MSP430FR6989 will that same pin out file with the launchpad pin numbers can be used, or is there any pins_energia file only for that IC with all the pin numbers for each pin, or should i modify it accordingly?, if needed to modify then what changes can i do to make it compatible please help.

    Thank you

     

    Getting fatal error assert.h on MSP430FR6989 while using the U8g2 128x64 lcd library

     Hello,

    Im getting an error while compiling the 128x64 LCD u8g2 library on msp430fr6989. I tried the hello world code on it full  buffer.

    I complied the same code on msp432p401r it compiled and even the display worked but the same code when changed the board to FR6989 its says fatal error assert.h no such file or directory, the screen shot is attached below.

    Please help me with it.

    Thank you

    128x64 Graphical lcd display interface with MSP432 or 430

    in Energia - MSP

    Posted

    Hello there,

     

    I have 128x64 graphical dot matrix display lying around with the driver ST7567,  so ive been thinking can i interface it with msp432 or 430?

    i found a library for arduino in github but when i added the library to energia and compiled it i get the following error attached below. I have attached the library and the screen shots below, in that library there are for many  lcd controllers i selected " U8G2_ST7567_JLX12864_F_4W_SW_SPI" it worked out fine on arduino.

    can any one help me out??
