logger_sd_spi_direct

Direct SPI SD Logger that saves pprzlog messages to SD Card. Supported SD cards: - SDv2 cards. Old SDv1 cards are not supported. - Both SDSC and SDHC/SDXC are supported. Some SD cards need to be zeroed out before use: https://askubuntu.com/a/511476 This module logs data directly to an SD Card which is connected on a SPI port. Logging can be started/stopped by setting sdlogger_spi.do_log from the GCS or by defining SDLOGGER_ON_ARM to TRUE. The values to be logged are defined in the telemetry config file. An example is available in rotorcraft_with_logger.xml. The logmessage is defined as the default message in the process “Logger”. A LOGGER_LED can be enabled which indicates if the logger is writing or reading data. Downloading of the data occurs over the configured serial device using sw/logalizer/sdlogger_download. There is no check to verify that all data is transfered. For UART it is recommended to use an FTDI cable.
