[0032] The following details the three processes of power-on operation, test program download, and burning test of this solution, in conjunction with the above specific implementation methods and accompanying drawings:

[0033] 1. Power on and run

[0034] Connect the +5 to +24VDC power adapter to the following connection: Figure 2 Connect the DC1 socket shown. Close the power switch SW1 to power on the device. The input +5 to +24V DC current is filtered by fuse F1 and C1 and C2 before being input to the DC / DC step-down circuit (including R1, R2, U1, C3, L1, C5, C6, R3, R4, C4, R5) centered around U1 (TPS54302DDCR). After passing through TVS1 and C7, it outputs +5V power. Part of the +5V power is filtered by U3 (AMS1117-3.3) and C15 and C16 to output +3.3V power V33, which supplies the main control circuit. The other part is filtered by U2 (AMS1117-3.3) and C9 and C10 to output +3.3V power, which supplies the CC1310 related circuits.

[0035] After the main control MCU U5 (SWM34SVET6) powers on and initializes all connected peripherals, it performs the following operations simultaneously:

[0036] a. Read the file information in the internal memory U6 ​​(W25Q1128JVSIQ), initialize the LCD module (LCD1), and display the UI interface;

[0037] b. Control the indicator light LED1 (operation indicator) to light blue and flash at a frequency of 1 Hz;

[0038] c. Listen to the "confirmation" key SW2, "up" key SW3, "down" key SW4, "start / stop" key SW5 input, and perform corresponding operations according to different key inputs;

[0039] d. Control the buzzer BUZZER1 to emit a key prompt sound ("beep") when a key is pressed;

[0040] e. Control the RST_CC pin to output low level, reset the CC1310 kernel.

[0041] 2. CC1310 test program download

[0042] Connect the device to the host computer through the USB cable. After pressing the "confirmation" key SW2 for more than 3 seconds, the host MCU U5 program enters the file transfer mode, and the device is connected to the host computer as a USB storage device. The host computer can download the CC1310 test program into the internal storage U6 (W25Q128JVSIQ) by copying, pasting, etc.

[0043] 3. Burn test

[0044] The burn test of CC1310 is carried out in the following steps:

[0045] a. After downloading the CC1310 test program into the internal storage, disconnect the power switch SW1 and then reconnect it to restart the device and enter normal working mode.

[0046] b. After the device is ready, the host MCU U5 controls LED1 to turn blue and flash at a frequency of about 1 Hz, while reading the file information in the internal storage U6 (W25Q1128JVSIQ), initializing the LCD module (LCD1), and displaying the UI interface;

[0047] c. Press the "up" (SW3) and "down" (SW4) keys to move the cursor to select a test program. After pressing "confirmation", the host MCU U5 writes the test program into the CC1310 chip through the adapter P2, P3, and sets LED1 to green constant. After successful completion of the burn, U5 controls the buzzer BUZZER1 to emit a "beep——" long sound, and sets LED1 to blue and flash. If the burn fails, set LED1 to red constant, and control the buzzer BUZZER1 to continuously emit "beep beep" alarm sound.

[0048] d.After the test program is successfully burned into the CC1310 chip, press "SW5" to start the program test. The main control MCU U5 continuously monitors the data received by the wireless module U9. After receiving a valid data frame, control LED1 to flash once quickly, and display the wireless signal strength on LCD1. After the CC1310 program runs normally, the CC1310 controls the IO indicator lights (LED_IO0-LED_IO9) to flash at a frequency of about 1 Hz, and sends wireless data packets at a specific frequency. If an indicator light does not flash, it indicates that the IO pin of the CC1310 chip is not in good contact or the IO is damaged.

[0049] During the test, the main control MCU U5 continuously detects the wireless signal strength of the receiving module U9. If the wireless signal strength is lower than a certain value, it is considered that the CC1310 transmission signal strength is not enough, and the test is failed. The buzzer BUZZER1 continuously emits a "ding-ding" alarm sound. The entire test process continues until the "start / stop" key SW5 is pressed again.

[0050] After the CC1310 program runs normally, it controls the IO indicator lights LED_IO0-LED_IO9 to flash at a frequency of about 1 Hz, and sends wireless data packets at a specific frequency through U8 and related circuits.

[0051] During this process, if an indicator light in LED_IO0-LED_IO9 does not flash, it indicates that the IO pin of the CC1310 chip is not in good contact or the IO is damaged.

[0052] The software program flowchart of the main control MCU and the CC1310 chip during the above running process is shown in Figure 5 and Figure 6 .
