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. --- projects/cli-test/mgmt-misc.h | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'projects/cli-test/mgmt-misc.h') diff --git a/projects/cli-test/mgmt-misc.h b/projects/cli-test/mgmt-misc.h index caf7024..b7eb4f4 100644 --- a/projects/cli-test/mgmt-misc.h +++ b/projects/cli-test/mgmt-misc.h @@ -38,6 +38,12 @@ #include "stm-init.h" #include + +#define FILETRANSFER_UPLOAD_CHUNK_SIZE 256 + +typedef int (*cli_data_callback)(uint8_t *, size_t); + extern void configure_cli_misc(struct cli_def *cli); +extern int cli_receive_data(struct cli_def *cli, uint8_t *buf, size_t len, cli_data_callback data_callback); #endif /* __STM32_CLI_MGMT_MISC_H */ -- cgit v1.2.3
