uh oh, I think the avr-gcc still makes its operations on 8 bits if both operands are 8 bits, so return ((resh << 8) | resl); effectively returns resl only.. try making a cast return (((unsigned int)resh << 8) | (unsigned int)resl); I think the (int) cast on resl isn't necessary, but lets try... also check with another
There i no way, you can use Atmel Studio 6 on Linux. There are alternative IDE's (ie Eclipse, or Code::Blocks) that work on Linux. And avr-gcc is working fine on linux (you can even download Atmels version for linux) Debugging is going to be a challenge though. /Bingo
I want to convert 24Hr-to-12 mode in RTC DS1307 with atmega16(11.0592Mhz). Its ok with 24Hr mode. For its solution i had referred its datasheet....and read about 24/12 hour bit but in my code i cant find that where i have to make that change so that i can convert that time in 12HR. Compiler avr gcc. #include <avr/io.h> #incl
dude, that's a I2C memory, not a microcontroller... what exactly do you need? an avr sample in atmel studio (avr-gcc? or avrASM?) to write an I2c memory (your at24c512) trough the TWI interface? (something like this could
I remember pablin did pong & tetris in a TV with a pic16f... I myself made some games with a GLCD with a PIC16F88 in Assembler and later ported them to avr-gcc for a Atmega32... please note my implementation could be very diff
I have used the library from ihsan Kehribar (which is made in avr-gcc) and it worked at the first try...
I am trying to implement a GPS module with avr Atmega32. I am finding difficulty in splitting the text read from GPS module, namely the $GPGGA line. I need to split segments of this line that are separated by commas and use the latitude, longitude and altitude for further processing. Any help in few line code to split this line will be very us
The reason is simple, the compiler is totally removing the for loop if there is nothing to do inside the loop. Generally compiler acts little bit smart on busy loops, gcc based compilers do this mostly. Now when you include the statement it is decreasing to 16KHz because the soft float implementation in avr will take more cycles. There is no hardwa
Please refer to this.
i have big problem to using array the array work until my array have 4 but after i add 5th number, avr starting joking.... Define "joking"
I am trying to do what arduino SHIFTOUT function does, but not sure how to code the following line in avr gcc : "digitalWrite(dataPin, !!(val & (1 << (7 - i))));" void shiftOut(uint8_t dataPin, uint8_t clockPin, uint8_t bitOrder, uint8_t val) { uint8_t i; for (i = 0; i < 8; i++) { if (bitOrder == LS
I would recommend using Code::Blocks rather than Eclipse for an IDE, Code::Blocks is also compatible with gcc distros like Mingw, avr-gcc, etc. Code::Blocks Code::Blocks Installation w/Mingw BigDog
Check this application note from atmel If you are using avr gcc, softuart library is available on the net
Hi, I have used avr microcontrollers before (using avr-gcc library) and the arduino platform. But for a project I have to use a PIC microcontroller for the first time. I have a few doubts: 1) I am planning to use pic32mx250f128b which has a built in USB. I wanted to know how easy will it to implement this USB functionality (...)
there is any starter guide with some example for gcc-avr or avr-eclipse & how can i found the lcd(16*2)(or other graphical) & other lib for both compiler
Dear kalbun I have a problem with building my Project in avrStudio4 with Winavr-gcc. I use some Library (avrlib) files in my *.C files. It could find included *.h files but it could not find the functions which are described in library .c files. Which configurations i must add in avrStudio to eliminate the (...)
Suggestion: If you use avr Studio or avr-gcc, it is much more simpler, and safer, to use for usart baud rate setting as it can handle the USE_2X bit automatically. Errors: F_CPU MUST be defined before including , if you don't get any warnings at compile time, then it is defined somewhere else, thus (...)
Only a guess (I don't use avr) but shouldn't you clear the interrupt in the interrupt routine or is it automatically done for you? Keith
The xy coordinated access one char at a time, there is no string type in C. There is a string manipulation library in libc that may come handy The eeprom access is done using You can read this tutorial d
where can i find built in functions used in avr gcc ?
