To do SCM Development UART,SPI and I²c are our most commonly used hardware interface, I collected the relevant specific materials on these three kinds of interfaces are explained in detail.UartThe UART is a universal serial data bus that is used for asynchronous communication. The bus bidirectional communication, can achieve full duplex transmission and reception. In the embedded design, the

Last year, noridc developed a chip that integrates Bluetooth 4.0 and can communicate with 24l01. The film encapsulation can be very small, and the power consumption is very low. It is very suitable for wearable devices, so I recently had a set of second-hand ak ii and no becon board. I first played some basic peripherals, And now I started to develop ble. Under the official SDK directory, we can find the project file Nordic \ nrf51822 \ board \ pca10001 \ ble \ experimental \ ble_app_uart, in ad

0 IntroductionWith the widespread popularization and application of embedded system, UART (Universal asynchronous Receiver Transmiller) is widely used as a serial data transmission method. The UART allows full-duplex communication on a serial link. Serial Peripherals to Rs 232-c Asynchronous serial interface is typically implemented using a dedicated integrated circuit, the

Find the source of a development environment that supports information about AVR, MSP430, and ARM-general Linux technology-Linux programming and kernel. For more information, see the following. The avr-libc of Ubuntu 8.04 is too old to feel bad. By luck, we found a third-party source. Http://think.objectweb.org/toolchains.html It contains three development environments: AVR, MSP 430, and ARM. I hope it will be useful to you. An environment th

(){ReturnReadkey ();} To implement scanf call, you also need to set it. For detailed settings, refer to: MSP430 library In this way, the scanf port of the keyboard is completed. to use it, you only need to include the stdio. h file, and then initialize the keyboard. Example: Here, the example implements simple interaction between the keyboard and the LCD. When the keyboard inputs data, the LCD is displayed normally, just like the keyboard an

LCD is one of the most commonly used display devices in single chip microcomputer systems.ProgramThe database is tested on the msp430f169 and msp1430f149 single-chip microcomputer and can be used with confidence. LCD uses the 12864 liquid crystal of the ocmj4x8c model and the control liquid crystal uses the parallel method, the three control ports are p3.0, p3.1, and p3.2, and the data uses the P5 data IO port.

Using MSP430 (f149) for infrared reception is simpler than sending. The infrared sensor I use is hs0038b. The original output is low when receiving a 38 K infrared. Otherwise, the output is high, we can start to writeProgramBecause there are many circuit diagrams of hs0038b, I will not post them here. The following is a specific example.Code: # Include Include the sorted infrared transmission and receipt. Here we will make a record. If you have a

Why I use P1out ^= 0x01; and p1out = 0x01^ is a different or calculated symbol so each operation is reversed. This operator, however, is maintained at a state of 1.P1out|=bit6 the value of P1out if it is 1, if it is 0, take the value of BIT6What do you mean, p1out |= BIT7?Define the P1.7, which is different from the definition of 51, 51 needs sbit, if you need to define p1.2,p1.3, you can write: P1out |=bit2 + BIT3, and then you can operate on it, such as P1out ^= BIT0, so P1.0 output high level

Today, it has been a long time since the JTAG download problem of MSP430. In the end, it is actually a problem with the port mode. In My bios, the default port is the SSP mode, but if JTAG is used, it needs to be changed to the ECP or EPP mode. after entering the BIOS to correct it, there is no problem, debugging is now available. There is another problem that I don't know why. I have bought a 430 Development Board for a long time and used it out. T

This section provides sample code for the msp430f5438a SPI Read and write SD card, using the official library msp430_driverlib_2_60_00_02, using IAR for msp430 6.3 by compiling. This section of the code does not differentiate the SD card, so only the SDHC card is operated, and the program is verified to work properly on the Kingston 8GB SDHC microSD card. sdhc.h #ifndef _sdhc_h_ #define _SDHC_H_ #define SDHC_INIT_CLK 125000 #define SDHC_HIGH_CLK 312

Abstract:Cp2101 and its upgraded product cp2102 are highly integrated USB-UART bridging circuits manufactured by the United States's silicon company. They can use the simplest external circuit, the least external device and the smallest area of the circuit board for easy conversion from USB2.0 to UART. This paper introduces the main features and practical application methods of the circuit. Keywords:Cp2101

Principles, differences and Applications of SPI, I2C, and UART Serial Bus 1. UART is a two-line interface. One transmission and one receiving interface can communicate with each other in full duplex mode, and the number of lines is relatively small. Data is transmitted asynchronously, with strict timing requirements on both parties, and the communication speed is not fast. It is used most frequen
