For details of the control registers, see the SCP1000 data sheet. 最近再做一个关于stm32f103系列单片机i2c通信的项目，因为以前没有玩过单片机所以有一些东西实在搞不懂，也没人可以咨询，所以来求教各位大牛了. Master/Slave capability. 24C08B/16B DS21081G-page 4 2004 Microchip Technology Inc. Each of the two UARTs on the wildcard is capable of full-duplex communications, meaning that both transmission and reception can occur simultaneously (although the RS485 protocol is half duplex as explained below). SPI (or Serial Peripheral Interface) is a protocol named by Motorola. The source code is developed by a large community of professionals and enthusiasts. SPI（Serial Perripheral Interface）串行外设通信接口，主要实现设备（主从）之间的通信。硬件上由CS、SCK、MISO、MOSI四根通信线连接而成。关于SPI更多介绍不再详细描述，本文主要以STM32F103为主机、W25Q16为从机进行SPI通信实验。. Download OpenVPN for free. 使用硬件IIC控制器 应该是官方的i2c_ee代码 读取24LC02的 不挂总线直接测试的时候会卡死在 while(!I2C_CheckEvent(I2C2, I2C_EVENT_MASTER_MODE_SELECT));这句话上 挂上总线，将I2C1的PB6 PB7外接上拉电阻拉高之后，打开 #define RT_USING_I2C_BITO. Its not just about reading this register that makes everything work, its that readying this register(or, as I stated in question, some other register in I2C, before toggling the STOP bit), does "something" , which makes possible proper STOP condition generation. On the SWD connector the pins PB13,PB14 are on pin 2,4 of the SWD connector. To turn off the LED blinking, master must write data byte 0x00. They also allow designers to use a smaller microcontroller rather than moving to a. STM32 microcontrollers are supported by a complete range of evaluation tools ranging from highly affordable kits to fully equipped, high-end application development boards. Решта портів працюють аналогічно. The book will guide you in a clear and practical way to this hardware platform and the official ST CubeHAL, showing its functionalities with a lot of examples and tutorials. How to use the high-density microcontroller to play audio files with an external I2S audio codec. if it uses ST HAL library, it will very nice. These routines are hardware independent and can be used with any MCU. STM32F103 devices use the Cortex-M3 core, with a maximum CPU speed of 72 MHz. STM32F103 vs GD32F103 round 3: UART - gStore - […] the part 3 of Sjaak's post comparing the GD32 to the […] Submit a Comment Cancel reply Your email address will not be published. The installation must be able to be done with Windows, but some sudden complications for the installation of the drivers, I propose you to compile and load the firmware from your Raspberry Pi. bin”When MCU starts ,If the file is existStart firmwareupdateelseJump user AppI’m using FLASH-FS to read firmware file from SD CARD, andwrite is mcu flash. 1、MDK工程目录（创建工程方式略)，工程结构与前面 "STM32F103 DMA模式操作UART" 类式. I want to use SPI master configuration and send some data just to capture it with Logic Analyzer. AN2824 I2C master programming examples (DMA, interrupts, polling) Doc ID 15021 Rev 4 5/16 1 I2C master programming examples (DMA, interrupts, polling) 1. USB interface tutorial covering basic fundamentals. This is exactly what I'm going to do today. The ADS7846 is a next-generation version to the industry standard ADS7843 4-wire touch screen controller. Trackbacks/Pingbacks. Blending all three communities together, the Embedded Pi helps you to get the most out of each platform. Converting a Blue Pill STM32F103 board to a Black Magic Probe Recently, I learned about the really awesome Black Magic Probe - an interesting JTAG and SWD adapter that essentially has its own, built-in OpenOCD server so you can use only the GDB client to connect directly to this device for debugging!. Contribute to avislab/STM32F103 development by creating an account on GitHub. println output for debugging. This has different setup instructions depending on the board you’re using. STM32F4 has capability to output different clocks on specific 2 pins. When looking at a few pages on the STM32; I was a bit skeptical on how easy it would be to program this board. In addition, the flags used are different – the IT flags are used instead. Here you can find tutorial about usage u8g2 library with stm32 MCU. To get going, I first read the FAT on [SD cards] tutorial by Thiadmer Riemersma and Claudio Toffoli of CompuPhase, and I really suggest you to read the 1 page of text under the heading “The Master Boot Record and the partition table” at this. Khung truyền dữ liệu là 32 byte data, tốc độ là 9Mbs/s, LSB đi trước, 2 bit 1 xung clock. I want to use SPI master configuration and send some data just to capture it with Logic Analyzer. Based on STM32 RF adapter (second board in post w/o RF parts). Each slave device also has a chip select (enable) pin, that is used for activating the device. Orange Box Ceo 6,452,956 views. 速度，跟51和AVR相比，相当快了。 2. AFAIR it was just simple while loop doing I2C transactions with infinite timeout. View and Download ST STM32F103 Series application note online. The picture above shows sending two bytes from master to slave and 1 byte back from slave to master, but the data is always zero. […] STM32F103 vs GD32F103 Round 1: Solderability | smdprutser. So depending on the design of your Chinese FR4 the firmware might be forced to service setup packet just after power-up (PITA debugging and restarting USB) if DP is hard-wired. ¹ The frame rate can be up to 125 Hz. I made a small 5×5 development board, soldered it up and started programming. 最近再做一个关于stm32f103系列单片机i2c通信的项目，因为以前没有玩过单片机所以有一些东西实在搞不懂，也没人可以咨询，所以来求教各位大牛了.
