Micro log library for embedded systems.
Simple example:
#include "ulog.h"
...
ulog_init(ULOG_STDOUT);
static const char* TAG = "i2c";
ULOG_INFO(TAG, "init");
ULOG_ERR(TAG, "sending rc:%d", rc);Set level of logging:
#include "ulog.h"
...
/* Init ulog. Print to stdout */
ulog_init(ULOG_STDOUT);
/* Set log level. Print message >= ULOG_INFO_LVL */
ulog_set_level(ULOG_INFO_LVL);
/* Will not print */
ulog(ULOG_STDOUT, ULOG_DEBUG_LVL, "spi", "send %d bytes", n);
/* Will print */
ulog(ULOG_STDOUT, ULOG_INFO_LVL, "uart", "init");
/* Will print */
ulog(ULOG_STDOUT, ULOG_WARN_LVL, "i2c", "wrong data: %s", err);Log into file system or stdout:
/* Init ulog. Print to stdout and file system */
ulog_init(ULOG_STDOUT | ULOG_FS);
/* Print to file system */
ulog(ULOG_STDOUT, ULOG_ERR_LVL, "protect", "overvoltage: %f", v);
/* Print to stdout and file system */
ulog(ULOG_STDOUT | ULOG_FS, ULOG_INFO_LVL, "can", "received id: %d cmd: %s", id, cmd);With timestamp, level and tag:
