TM4C123GH6PGE: S76SXE interfacing to TM4c123gh6pge microcontroller

Part Number: TM4C123GH6PGE
Other Parts Discussed in Thread: EK-TM4C123GXL

Hello everyone,

                 Thanks for your suggestions in my previous posts,

I want to start communication with LORA  S76SXE module. I am new to this and i want to start communication between two S76SXE modules. Means i want to take the input from sensor and transmit through first LORA module to second LORA module wireless and interface to two TM4C123GH6PGE modules using UART communication. I request you to please suggest me how to implement this communication.

Thanks,

Regards,

Srinu.V.

  • What is LORA S76SXE? Google search doesn't reveal anything. If you want to communicate to the MCU using UART then I will suggest you start with the TivaWare UART examples. You can find them in <TivaWare_Installation>/examples/peripheral/uart and <TivaWare_Installation>/boards/ek-tm4c123gxl/uart_echo.
  • Hai sir,

    Sorry for the spelling mistake .It is EK-S76SXB.

    It is a LORA module from AcSIP.



    Thanks,

  • Thanks for the clarification. Again, if you want to communicate to the MCU via UART then please start with the examples that I provided earlier.
  • Thank you sir,

    But i have a confusion to how to initialize one LORA (Transmitter) module to one TM4C controller and another LORA (Receiver) module to another TM4c controller for wireless communication.

    I request you to please suggest me how to do this.

    Thanks,

  • Hi,
    I'm clear with your question, perhaps due to the fact that I'm not familiar with the LORA device. I thought you wanted to communicate between the LORA device with the TM4C via the UART interface. If this is not the case, can you draw some diagrams showing how they are to be communicated.

    There is a TI design system example demonstrating how to build a secure cloud-connected IoT gateway allowing access and control of the multiple wireless nodes that you may find helpful.

  • Hai sir thanks for your valuable suggestion,

              I draw one block diagram regarding my experiment for point to point communication by using LoRa transmitter and receiver module. Please find the below attachment.

    I request you to please suggest me how to implement this task.

    Thanks,

  • Hi Srinus,
    Thanks for the diagram. I don't think there is much I can offer to help here as I'm not familiar with the LoRa module. Does the LoRa module contain a processor in it? You will need to read the LoRa datasheet on how to configure the transmitter/receiver and how to communicate with the TM4C123 using UART. The LoRA module and TM4C123 must be configured for the same bauld rate. As I said, I suggest that you start with a simple UART example from TivaWare library and get a hang of it on how it works from the TM4C123. Observe the UART TX/RX pins to see how they behave. Once you feel comfortable with the TM4C123 UART then you can dive into how to send the commands/data to the LoRa module. The key thing is to properly configure the LoRa module to receive UART commands/data so it can send/receive wireless-ly between each other.
