Serial port class Two ttl modules are used on win computer You can see the information of another serial port when inserting. The other serial port I see here is COM11 You need to install the serial port tool in advance. Here I choose the conda environment, so I just switch to the virtual environment, and then install pip Let's start wi ...

1, RT thread 1. Introduction RT thread nano is a minimalist version of hard real-time kernel. It is developed by C language, adopts object-oriented programming thinking, and has a good code style. It is a tailorable, preemptive real-time multitasking RTOS. Its memory resources are very small, and its functions include relatively complete ...

summary S32K1 has rich Timer resources. Today, we start with the simplest LPIT. LPIT: low power periodic interrupt timer. LPIT is a periodic interrupt timer with multiple timer channels. When a timer reaches the programmed count value, the corresponding channel will generate pre trigger and trigger output signals, which can trigger other modu ...

summary By analyzing the official S32SDK of NXP S32K1, this paper analyzes its DMA code, so as to better use DMA in the future. virtual channel In MCU, there may be 1- multiple DMA instances, and each instance has several different numbers of DMA channels. Therefore, the concept of virtual channel is introduced into the DRV of S32SDK to ...

This article can be regarded as an end to the smart car. Later, we'll see if we can share other things. It's a little lazy. At first, we thought about whether we can be Zhou Geng, and finally it became Nian Geng. hhh, I don't know whether the things mentioned before have helped you. The electromagnetic loop is divided into several parts. First ...

About the program I wrote, there's nothing to upload I've been taking notes with txt before, but later I thought of writing it on csdn because there was too much code The following is the text, in no order, where you want to write. Some basic -In the 138 decoder, the first three bits represent 5, 6 and 7 P2=0xA0 corresponds to 1010 0000, th ...

Design requirements Use DMA to move data from memory A to memory B 1, Basic knowledge DMA (Direct Memory Access) Direct Memory Access can greatly reduce the workload of CPU. The CPU executes instructions according to the content of the code. Among these instructions, there are instructions for calculation, control program and data tr ...
