T-SIMCAM Groove interface

[EvanChristan123]

Hi there, I have a few questions related to the groove on T-SIMCAM:

1. Can I use groove as gpio instead of serial?
2. is it compactable with seeed studio grove LED products? If yes , how can I work with these products? Do I need any converter with that?
3. Is there any example of using the groove interface on T-SIMCAM?

Hope somebody can help with that, thanks!

Nope

Nevertheless, base on #33, with 4 pin Female Jumper to Grove 4 pin Conversion Cable (https://www.seeedstudio.com/Grove-4-pin-Female-Jumper-to-Grove-4-pin-Conversion-Cable-5-PCs-per-PAck.html?p=2#detail-target-2) help, we can use Groove interface as addition gpio ports to control non-grove module, maximum 2 gpio ports provided I think

if u look at this issue we can see the groove connector has an issue and is not compliant with groove standard so that needs to be fixed as well, and the pin mappings written in there seems to be correct

That answered my second question

The groove interface can be configured as serial or GPIO or I2C.
You only need to pass in the specified Pin during initialization.
For example,
I2C

Wire.begin(43//SDA,44//SCL); 

Serial

Serial2.begin(115200,SERIAL_8N1,43//RX,44//TX)
