You can manipulate the internal register values directly from BASCOM. They are also reserved words. Each register acts like a memory location or program variable, except that the bits of each byte have a special meaning. The bits control how the internal hardware functions, or report the status of internal hardware functions. Read the data [...]

AVR Internal Hardware
The AVR chips all have internal hardware that can be used. For this description of the hardware the 90S8515 was used. Newer chips like the Mega8515 may differ and have more or less internal hardware. You will need to read the manufacturers data sheet for the processor you are using to learn about the special [...]

PIC Programming Tutorial With PICALL Software
You can learn how to make the PIC Programmer (Tutorial) here. Install and run the PICALL programming software. You can download the PICALL installer for free from this link: http://picallw .feniks-pro.com/zip/paw016.zip As shown in Figure, select the P16PRO (instead of PICALL) from the drop-down menu. If the P16PRO board is powered up and connected to [...]

USB Microcontroller Programmer
The PICkit™ 1 FLASH Starter Kit is a low cost programmer for Microchip’s 8/14-pin FLASH microcontrollers. On the surface, the PICkit 1 is an easy to use programmer. What may not be so obvious to its user is the PICkit 1 is also a useful design example illustrating primarily two things: (1) a Windows®-based low [...]

linux microcontroller programming
Other than using Windows Operating System, AVR microcontroller programming was also done on the Linux Operating System. Linux also is available on software that can be used to perform programming, one of which is kontrollerlab software. Kontrollerlab is a GUI-based Linux software programming that can be used easily as we like to use AVR microcontroller [...]

programming The Microchip PIC in CCS C
Basics All computer programs have a start. The start point in Microcontrollers is the reset vector. The 14 bit core (PIC16Cxx family) reset at 00h, the 12 bit core (PIC16C5x and 12C50x) reset at the highest point in memory – 1FFh, 3FFh, 7FFh. The finish point would be where the program stops if run only [...]

motor driver program in the AVR microcontrollers using BASCOM
Most of AVR microcontrollers have PWM channel in its chips. This facility makes use PWM become simpler and more accurate. Timer or Counter in the AVR can be used in PWM mode without disturbing the basic functions of the timer. Timer1 can be pre-configured in PWM mode by setting bits to the register PWM11 and [...]

OPERATIONAL AMPLIFIERS : part 10 (Differentiator and integrator circuits)
By introducing electrical reactance into the feedback loops of op-amp amplifier circuits, we can cause the output to respond to changes in the input voltage over time. Drawing their names from their respective calculus functions, the integrator produces a voltage output proportional to the product (multiplication) of the input voltage and time; and the differentiator [...]

USING RS485 serial communication
RS485 RS485 is used for serial communication and well suited for transmission over large distances. Similar to RS232 we need a level shifter. sample above uses a MEGA161 or MEGA162 which has 2 UARTS. This way you can have both a RS232 and RS485 interface. The RS232 is used for debugging. In order to test [...]

Memory usage in avr microcontroler
SRAM Every variable uses memory. This memory is also called SRAM. The available memory depends on the chip. A special kind of memory are the registers in the AVR. Registers 0-31 have addresses 0-31. Almost all registers are used by the compiler or might be used in the future. Which registers are used depends on [...]
