Add i2c_get_index for consistency - just calls i2c_hw_index
it would be useful to lock the release/tag for projects that depends on the pico-sdk. We can use PICO_SDK_FETCH_GIT_TAG to specify a release tag for the Pico SDK to download....
To make stdio logging quicker it's probably a good idea to set the default uart speed 921600, but it's only configurable by adding this define to your project. Make it...
I have a project where I want to get a callback for when I receive characters from the stdio USB virtual serial port. It works fine if I call `getchar`...
Hi, I am working on a Pimoroni RP2040 product that involves regular communication with some onboard I2C devices at 400KHz. During my testing I was encountering frequent lock-ups after a...
Using FreeRTOS-Kernel-Heap3 library leads to deadlock across cores, race condition on core spinlock
I describe the full issue here: https://forums.freertos.org/t/multicore-smp-rp2040-port-deadlock-when-using-heap-3/19255/ In summary, FreeRTOS heap_3 calls `vTaskSuspendAll` which grabs the task lock before calling malloc/free. At the same time, if another task is using...
