^ Overview

2021-10-01 - This page to become central point on Neela Nurseries wiki for Zephyr RTOS notes, references and findings.


^ High Level Zephyr Topics

Zephyr RTOS documentation (latest) regarding sensor API, with explanation of enumerations sensor_channel and sensor_attribute:

High level topic "sensors":


Existing Zephyr notes on this wiki remain to move here. Note on Zephyr without threads:

What's this mbetutils test of snprintf() about? Found while searching for Zephyr use of snprintf() function in ~/projects/zephyr-based/z4-sandbox-kionix-work/zephyr:

./tests/crypto/mbedtls/src/mbedtls.c:65:#define mbedtls_snprintf   snprintf
./tests/crypto/mbedtls/src/mbedtls.c:89:static int test_snprintf(size_t n, const char ref_buf[10], int ref_ret)
./tests/crypto/mbedtls/src/mbedtls.c:95:	ret = mbedtls_snprintf(buf, n, "%s", "123");
./tests/crypto/mbedtls/src/mbedtls.c:108:static int run_test_snprintf(void)
./tests/crypto/mbedtls/src/mbedtls.c:110:	return (test_snprintf(0, "xxxxxxxxx", -1) != 0 ||
./tests/crypto/mbedtls/src/mbedtls.c:111:		test_snprintf(1, "", -1) != 0 ||
./tests/crypto/mbedtls/src/mbedtls.c:112:		test_snprintf(2, "1", -1) != 0 ||
./tests/crypto/mbedtls/src/mbedtls.c:113:		test_snprintf(3, "12", -1) != 0 ||
./tests/crypto/mbedtls/src/mbedtls.c:114:		test_snprintf(4, "123", 3) != 0 ||
./tests/crypto/mbedtls/src/mbedtls.c:115:		test_snprintf(5, "123", 3) != 0);
./tests/crypto/mbedtls/src/mbedtls.c:185:	 * Make sure we have a snprintf that correctly zero-terminates
./tests/crypto/mbedtls/src/mbedtls.c:187:	if (run_test_snprintf() != 0) {
./tests/crypto/mbedtls/src/mbedtls.c:188:		mbedtls_printf("the snprintf implementation is broken\n");
