Log on a SD card, either text or binary data.

Based on ChibiOS HAL and Threads. If board allows it (ex: Apogee), the log file is automatically closed on power down. Files are written on a FAT file system using the FatFS library and can be accessed by using the autopilot as a mass storage (plug USB while the board is running).

Example for airframe file

Add to your firmware section: This example contains all possible configuration options, not all of them are mandatory!

 <module name="tlsf"/>
 <module name="logger_sd_chibios">
   <define name="SDLOG_START_DELAY" unit="s" value="30" />
   <define name="SDLOG_AUTO_FLUSH_PERIOD" unit="s" value="10" />
   <define name="SDLOG_CONTIGUOUS_STORAGE_MEM" unit="Mo" value="50" />
   <configure name="SDLOG_LED" value="none|num" />
 </module>

Module configuration options

Configure Options

name: SDLOG_LED value: none|num
Description: LED number or 'none' to disable. Default: none

Define Options

name: SDLOG_START_DELAY value: 30
Description: Set the delay in seconds before starting the logger. This delay can be used to get plug USB cable and get data without starting a new log. Default: 30s
name: SDLOG_AUTO_FLUSH_PERIOD value: 10
Description: Data flush period. Shorter period may decrease performances. Default: 10s
name: SDLOG_CONTIGUOUS_STORAGE_MEM value: 50
Description: Try to reserve a given contiguous mass storage memory. Default: 50Mo
