2016-06-02Use DMA for UART RX instead of interrupts.Fredrik Thulin
DMA is more efficient and less prone to miss characters than interrupts. An open question is if circular mode is really the best. If someone copy-pastes more than the RX buffer size of configuration into the CLI, we risk the DMA controller catching up with the reader and overwriting data not yet read. Since we don't have flow control back to the users terminal, we will always fail if too much data is entered before we can process it. The question is if failing to stuff new data at the end of a buffer might be better than data being overwritten - thus messing up the commands in unpredictable ways.
2016-05-16Use baud rate 921600 instead of 115200.Fredrik Thulin
Don't want to wait longer than necessary for firmware file transfers.

2016-05-13Implement support for the two UARTs on the alpha board.Fredrik Thulin
2016-05-12Test both UARTs, and also test receiving data.Fredrik Thulin
2016-04-24This time for sure - async receive, and everything that flows from that.Paul Selkirk
2016-03-16Added uart_recv_char() to support RPC.Paul Selkirk
Moved hal_io_fmc.c to libhal repo.
2015-11-11Lots of cleanup.Paul Selkirk
Clean up and simplify(?) Makefile. Add copyrights as needed. Add include guard to stm-fmc.h. Move MX_USART2_UART_Init back to stm-init.c for possible copyright reasons. Move libc, src, and include files to top level.
