Re: Connection confusion

Hello, Different interfaces on Base Shield use the other 2 pins for different purpose. For example, 4 pins of UART are GND, VCC, TX, RX, while TX and RX are used for data transmitting and receiving. By modifying pins configuration in the source code you can determine what pin you want to use. BTW, d...

Re: Is there a Grove connector eInk display?

Hi there~

Yes, it is. It can be connected to port UART of Grove-Base Shield and we also have another Triple Color E-Ink Display whose dimension is 1.54''.

Here is the link:

Re: control Grove RGB LED Ring and Seeeduino V4.2 under Matlab

Hi there~

In theory it's possible to control Grove RGB LED Ring and Seeeduino V4.2 under MATLAB but I'm so sorry we don't have such code.

Thanks sincerely,
JL

Re: XBEE SLEEP_RQ and CTS signals on Stalker V3.1

Hi Todd According to documents, If you enable hardware flow control (D7 command), the CTS pin asserts (low) when the device wakes. There are two figures. Figure 1 shows where the CTS port is, and figure 2 shows the schematic of Stalker. You can see it's not connected to ATmega328P MCU. You need a ju...
