Summary on program burning of AVR (tested ipv8) Single Chip Microcomputer

Recently, I made a joke and continued to play the learning AVR (mage8) microcontroller. I am still so familiar with it. However, this time it was a little difficult, and it was not suitable for the first time. The program cannot be downloaded !!!! Of course, the biggest reason is the download tool. If you are not using the usb isp download tool, it may be different from mine. Of course, it is not here to blame those who developed usb isp. I admire the

What did I do when I started the AVR application (head. s)

Because our firmware does not want to use the C library, the linker script and C-runtime both need to be written by themselves, but they have not been written yet. It is nothing more than a few lines of the C library. There is nothing to say, so we will write the main record of the avr c-runtime: 1. set the interrupt vector table (vector), which is defined in Datasheet. Each chip is different, and the number of vectors is also different. To achieve

How to create an AVRGCC project under AVR Studio

Serial Port and PC communication code based on AVR (uart8-bit data ), In order to continue to improve the function based on this code in the future, we will put the code here and learn it with everyone. /************************************AVR clock: 8.00 MHz * 8-bit data with a baud rate of 9600 (51) and 1-bit data is stopped. When the baud rate is set to 19200, UBRR = 25, 4800 = 103 * Note: The best baud

Arduino when avr Development Board

The principle is not complex, because arduino is already a database with a bunch of avr +, just find a tool that can compile and translate hex and download it to the board. However, we still encounter many problems. First, make: Interrupt/Exception caught (code = 0xc00000fd, addr = 0x4217b3) appears during eclipse + avr plugin compilation) Make cannot contain spaces like Program Files in the path. Copy o

Old text backup: AVR read-write EEPROM analysis

Since the EEPROM write cycle of the AVR is longer (generally milliseconds), special attention should be paid to it during programming. There's nothing to say about reading an EEPROM, it takes 4 clock cycles to read a byte of data, it can endure, it's more troublesome to write, Although the data placed in the EEPROM is not frequently accessed, although it is possible to use the read-compare-write mechanism to reduce the EEPROM write operation frequency

Repeat MCu-set up the AVR download Environment

author cldio often rode a horse named pony. to commemorate his horse, he named the software ponyprog (pony programmer ). Of course, this is just "said ". You can download the latest version of ponyprog from the clodio personal homepage http://www.lancos.com. Although the latest stable version is v2.06, we do not recommend that you download it because this version (and earlier versions) does not support newer AVR Microcontroller (such as tiny13 ).

How to use C language to manipulate the I/O port of AVR (taking iccavr as an example)

How to use C language to manipulate the I/O port of AVR (taking iccavr as an example ): Example 1: Define pb0 as output and output as high Ddrb = bit (0); // defines pb0 as the output. Portb | = bit (0); // pb0 outputs a high level Example 2: Define pb0 and PB1 as outputs, and pb0 outputs Low levels. PB1 outputs high levels. Ddrb | = bit (0) | bit (1); // defines pb0 and PB1 as the output. Portb | = bit (0) | bit (1); // pb0, PB1 output high level

Selection Guide for AVR MCU

Atmega169 tqfp package mainly has the following models: ATmega169V-8AU, ATmega169V-8AI, ATmega169-16AU, ATmega169-16AI. Model ID description:(1) The difference between "V" and "V": the voltage range supported by "V" is 1.8-5.5 V. If "v" is not provided, the supported voltage range is 2.7-5.5 V.(2) The numeric part of the suffix represents the maximum system clock that MCU can support, such as ATmega169V-8AU and ATmega169V-8AI refers to the system clock that can support up to 8 MHz. While ATmega

[003] AVR Microcontroller controls Light Emitting Diode

microcontroller uses this port to control other circuits, it needs to modify the port level value, which will affect the original level value. So we need to use latches to maintain the original level, and it will not be affected by the new level value of the port.

AVR Hardware Design

(general-purpose registers and I/O registers) are also zeroed by the reset operation.There are 5 reset sources for the ATMEGA16 microcontroller, which are:1, power-on reset. When the system supply voltage is lower than the power-on reset threshold Vpot, the MCU resets.2, external reset. When the external pin reset is low and the low duration is longer than 1.5us, the MCU resets.3, the power-down detection (BOD) reset. When the BOD is enabled and the supply voltage is lower than the reset thresh

Bit operations in the avr c Language

Bit operationOne common task is to program the microcontroller MCU to enable or disable some bit of the IO register. Fortunately, standard C has good and applicable bit operation functions, without the help of assembly instructions or other non-standard C structure C defines some bitwise operations that are very useful.A | B-bitwise OR this expression indicates that A is bitwise OR operated by B in the expression. This is usually used to open some bits. | = For example, Porta | = 0x80; // open
