Hi, I need help for Writing some data in mmc the read specific data from mmc and display on the LCD. If anyone shares with me some example it will help me a lot. You will find the circuit with this post. If I press the "Button 1" one string (ex. This is text number one) will write on the mmc. Button 2 (...)
hi my friend i want to write to mmc(sd) with avr and compiler bascom +avr_dos . i can write in mmc but i want to operation TAB between 2 varibale when i write in mmc . please help me thank you
I would like some help in selecting the simplest micro-controller for my project. I will have 22 momentary SPST switches and 22 very small relays whenever a switch is pressed (regardless how long the button is held down for) a corresponding relay will fire for 3 seconds. So I need a minimum of 44 general purpose io lines. I have a $300 budget. w

Hi, Microchip provide SD/mmc stack for its various microccontrollers (pic18 and above). Select a microcontroller read the stack documentation. There are a lot of example that will help you in developing your application. One more thing which dsPIC controller are you using? dsPIC30 or dsPIC33. For dsPIC30 you have to edit some files so that the stac

hi.... i have a need to design blood pressure devices using the PIC16F877, in my case, the data is need to be save in the memory card, but i don't have the code to write the data into the memory card.. can somebody help me? this is my email : manjung_4@yahoo.com thanks for all your help..
Hi adm1, You may use MikroC compiler and it has got built-in functions for accessing sd/mmc cards. See its help files.
Hi, If you download the mikroBASIC or mikroC or mikroPASCAL compiler, there are examples for writing to mmc card, although they use the mikroElektronika library functions. You might want to take a look. Hope this helps. Tahmid.
