I need some advice how to fix the 3 failing tests.. |
|
Need some help for solving the stm32_metapac::i2c issues. Locally the code does build for stable and nightly. So why not on the build server? Is it possible to remove the $HOME/.cargo/bin/git/checkout/* directory on the build server, then try again? |

Hereby a proposal for a i2c slave for the stm32.
Goal is to support a slave module with 2 addresses (module address and generic address), which can handle a (limited) burst of transactions from the master (in arbitrary order) in real time.
One can prepare 2 read transactions in embassy context (non real time). The transactions are handled in interrupt context (real-time), and the results are collected in a channel. The transactions can be one by one handled in embassy context, and new transactions can be prepared.
I did choose to make the buffer size NOT generic. Using generics (like generic_array) for the buffer size makes the code (and error messages) extreme complex.
Functionality is tested with tests i2c_master and i2c_slave in the examples/stm32g0 directory.
Note that this branch is a follow up of branch feature-i2c-slave.
