I2C and Block Factory

I am trying to use the hardware I2C for use with Grove Modules. The existing blocks do not seem to allow a write to a memory location and I cannot write data from variables.

I have tried to create a new block and copied the stubs into the I2C files. The new block does not appear on the list.

I tried to duplicate an existing I2C block and change its name (and the names in the block). Again it did not appear on the list.

In both cases, I restarted BlocklyArduino.

I checked the documentation but couldn't find anything to help.

Can you point me to any documentation on the topic?

Thanks for all your help.

Hi,
really sorry about the I2C block, can you send screen capture of the bad ones please?
I hope this old wiki could help: http://technologiescollege.fr/wiki/doku.php?id=fr:arduino:blockly_rduino:creerblocsmultiling and the english version is deprecated http://technologiescollege.fr/wiki/doku.php?id=en:blockly_rduino:create_blocks
No time for that, sorry.
With specific files and asking on forum, you could have help.

Thanks for the documentation,it has enabled me to create a custom block.

Here is more information about the I2C problem. I need to use the Hardware I2C to communicate with the Grove Shield. The blocks available are as follows.

I can use the blocks to successfully read a device such as the PCF8591 ADC but I can only write data by setting a constant in the Write block. There does not seem to be any way of writing data from a variable. There is also no direct way of writing data to a memory location.

I can control motors using UIFLOW with the following blocks.

Although I haven't looked in detail, I think there may be a similar problem with the Software I2C.

Thanks for all your help.

Hi,
I've not tested this blocks, I've not created them...so if there's any bug, feel free to fix it and send a patch.
Any help is welcome!
Thanks.
