"FreeRTOS Source Code Detailed Explanation and Application Development: Based on STM32" is supplemented by a large number of routines to comprehensively explain the principles and source code of FreeRTOS. The main content includes task management and task scheduling, system reduction and configuration, time management, queues, semaphores, software Timers, event flag groups, task notifications, low-power Tickless mode, idle tasks and memory management, etc. At the same time, "FreeRTOS Source Code Detailed Explanation and Application Development: Based on STM32" is equipped with a large number of illustrations, which is a good choice for those who want to learn the principles of RTOS systems in depth.
I use 149 single chip microcomputer and DAC5571 to synthesize sine wave, and use the table lookup method to synthesize, but I find that the output frequency is generally only a few hundred Hz at most,
It's been a long time since I got the board, but I haven't started to play with it. I used to be a loyal fan of atmel, from 51 MCU, arm7 (s64), arm9 (9200,9260, etc.), it can be said that my technical

I'm making an electronic keyboard recently, using a 51 chip, but I can't tune the corresponding tone. Please help me, is there a problem with the circuit or the program? My idea is to generate a squar
The microcontroller is PIC16F688. I use the interrupt function void interrupt isr (vvoid) {...} and it stops in the interrupt after running, but does not enter the above interrupt function. Is the for
