Re: Suggestion on references for working on Seeeduino board with gps with loriot server(raspberry pi3 as gateway)

For your first question, when rerun the procedures, your board didn't work. That is because your board would not connect the server automatically unless your write setup code for it. You can refer to the following code. void setup(void) { dht.begin(); SerialUSB.begin(115200); //while(!SerialUSB); lo...

Re: Seeeduino LoraWan with Grove-TF Mini LiDAR

Hello, I implemented your code, it works well when I have replaced unsigned int t1 = Serial1.read(); //Byte3 unsigned int t2 = Serial1.read(); //Byte4 with unsigned char t1 = Serial1.read(); //Byte3 unsigned char t2 = Serial1.read(); //Byte4 https://github.com/SeeedDocument/forum_doc/blob/ddec2926be...

Re: Stalker v3.1: Question re: I2C selectable voltage

Hello, Do not worry, look at the shifter circuit in schematic there. When you plug in grove of 3.3V or 5V directly, the circuit will match the level automatically. https://github.com/SeeedDocument/forum_doc/blob/582b95e2495ffec87d143b8d1c55dbdd238bbf9f/image/QQ%E5%9B%BE%E7%89%8720190201163756.png?ra...

Re: Arduino R3 UNO + 1.2 CAN BUS, stuck at init, HELP

Hello, Could you please show me how you connect both boards? Thx Here is the right method to connect them. Make sure you have plugged those pins into the position. https://github.com/SeeedDocument/forum_doc/blob/a5304b816ee7ab90b56858ac6d745fff67fd3bc9/image/QQ%E5%9B%BE%E7%89%8720190201154807.jpg?ra...

Re: Seeeduino LoraWan with Grove-TF Mini LiDAR

Hello,
I'm not very sure, but are you sure this line code to definate as unsigned int instead of unsigned char correct?

Code: Select all

            unsigned int t1 = Serial1.read(); //Byte3
            unsigned int t2 = Serial1.read(); //Byte4

I
Could you please post how you connect the wire?

Re: MP3 player 2 with ESP32?

Hello, You need to change the pin number definition in the code first before you compile the example code. The pin definitions of esp32 are different from those of Arduino boards. Here is their 1-to-1 relationship. https://github.com/SeeedDocument/forum_doc/blob/0cf3d6177f6dfb5c7897bb6fc36c8461778e3...

Re: Lipo Rider PRO overVoltage

Hello, I'm sorry to tell you that it looks like there is no Triode on this board so it can not protect itself from high voltage. It looks like that your smoothing capacitors are burned, so the voltage of this board become instability. You can try to switch them, but I can not say there are no proble...

Re: GPRS shield turns off on incoming call

Hello,
Sounds that you have already solved your problem, using USB for powering is a common mistake, I even burn my USB interface when I am a novice.
Thank you for your support.
Good luck!

Re: Can Bus Lighting Control System

Hello, “Message Sent Successfully” showed you can initiate your shield successfully, there is no problem with your hardware. But “Error Initializing MCP2515”. was also shown in some examples, so I guess that you forgot to check this line of code, the value is 9 or 10, which depends on shield version...
