STM32-HAL library 09-CAN communication (loopback mode)
1. Materials used: STM32F103C6T6 Minimum System Board STM32CUBEMX (HAL library software) MDK5 Serial debugging assistant 2. What you learned: Preliminarily learn how to use the CAN communication function of STM32. In this chapter, we mainly achieve the effect of on-board CAN communication, that is, 32 sends CAN information and then prints it out through the […]

oracle switches temporary table spaces, creates indexes, creates temporary tables, and creates large and small table spaces
1. The temporary table space of the switched database is temp1/the undo table space of the switched database is undotbs01 1. View the table space of the current database select tablespace_name from dba_tablespaces; It was found that there are no above two table spaces. 2. Create temp1 temporary table space and undotbs01 table space #Create […]
[Link loading and libraries] Organization of Linux shared libraries
Organization of Linux shared libraries Due to the many advantages of dynamic linking, a large number of programs have begun to use the dynamic linking mechanism, resulting in an extremely large number of shared objects in the system. If there is no good way to organize these shared objects, the shared object files in the […]
PHP uses recursion to integrate its two-dimensional array into a hierarchical tree, where the hierarchical id is in a uuid format. The weird problem has been solved.
No more verbosity, just go directly to the source code. <?php function findChildren($list, $p_id){ $r = array(); foreach ($list as $k => $item) { if ($item[‘fid’] == $p_id) { unset($list[$k]); $length = count($r); $r[$length] = $item; if ($t = findChildren($list, $item[‘id’])) { $r[$length][‘children’] = $t; } } } return $r; } function findChildren2($list,$p_id, & amp;$sike=[]) […]
