Re: CAN Bus shield 2.0 OBD Jumpers

Hi Alex~

You can connect the DB9 default to OBDII directly without cutting the pads and soldering to right pads. If you solder to right pads, please make sure the OBDII singals also swaps, or else, both DB9 CANH and CANL signals will be connected to OBDII GND singal. thanks.

Re: FastLED 3.3 and Grove - RGB LED Ring

Hi there~ Yes, it is compatiable. You can test with below 2 examples. example #1: just turn one led red and off #include <FastLED.h> // How many leds in your strip? #define NUM_LEDS 20 // For led chips like Neopixels, which have a data line, ground, and power, you just // need to define DATA_PIN.

Re: Event based Grove button v1.2 in grove pi+

Hi Babu~

Do you mean the falling/rising edge trigger function? I checked the dexter python library that it does not include the edge trigger function. You can post a question to https://forum.dexterindustries.com/c/grovepi, dexter team will reply the issue directly. thanks.

Re: Cannot upload the code to Hercules Dual 15A 6-20V Motor Controller

Hi there~ The bootloader on the board is quite old. You have to update the bootloader first and then you can program the arduino code from serial directly.  I use the arduino uno to burn the controller bootloader by following below instructions. https://www.arduino.cc/en/Tutorial/ArduinoISP   Then y...
