Re: Problems with powering Pmod Grove RTC using backup battery

Hello,
that means, when you use a 3v battery, you can not use 3.3v as the VCC, but 3.3v can still be used as a logical level.
And most boards of 3.3v as logic level provides a 5v pin. So you just need to connect the 5v pin to VCC pin of the grove by a jumper and then it can work.

Re: Does mic_array.get_direction (from mic_array.py) work?

hello, pls switch your mic_array.py with the following code. Then it can work with 6-mic array. The mic array detects all the voice source in the environment and it is also reflected in the results of the program.so the results seem to be mixed with random numbers sometimes…but you can still find th...

Re: Possibility of using GSR

Hello,
Why not? The GSR module output simple Analog signal. You just need to write the ADC program for FPGA yourself then it can work.

Re: Music Shield V2.2 opening a specific folder

Hello, I'm sorry for that I have read the music shied library and it does not support to retrieve subdirectories. But why not classify your music like this? It can also help you to find what you need. Links: https://github.com/SeeedDocument/forum_doc/blob/a607ae55d53db7193a1d63610d911e75a51171b8/ima...

Hello, I have heard a loooooooot of problems about Linkit One's I2C port, the problem is that its official I2c library sucks, and can not compatible with many code based on standard Arduino Libraries unless you rewrite your code or the MTK update its library.

Re: RTC not working together with 'digital light sensor'

Hello, I tested the official example while digital light sensor and RTC are all pulged on the i2c bus, but did not meet your problem. Only if the RTC is not on the bus it happens(In fact the serial data received means all i2c data is 255, maybe it can not read anything). Are you sure you have reset ...
