Feather-sized SAMD51 with M4 core serving as UART bridge to WROOM ESP32
There's a known issue with NINA firmware on the SAM32v2.4 causing it to dominate the SPI bus. This causes intermittent issues with concurrent ESP32 and SD card access (for example)....
IoT projects can be difficult on university campuses when dealing with WPA2 enterprise access points.
The same way folks are building micropython/circuitpython to runon embedded hardware, another effort is underway for Rust. Would be neat to get this up and running on the SAM32! Master...
Looks like adafruit is also exploring the idea of using the ESP32 as a "co-processor." See the link before for getting started.
Both SAMD and ESP are configured as masters on the SPI bus to the SD card. If, through software mis-configuration, they both try to access the SD card at the...
