Hi,
I working on a project that involves developing an automatic floor scrubber. I am using plantery gears for my project. Could someone please advise me on this project. Are there any good books to be recommended?Any form of help would be greatly appreciated. Thank you.
pic16f877 sd card
Hi,
I am trying to interface a SD card to PIC16F877 microcontroller. The purpose is
to develop a datalogger.( There would be a sensor that would be interface to the PIC and the sensor readings would be recorded onto the SD card). The readings stored would than be read...
Hi Silvio,
I have tried to read through the manual for the past 2 weeks, but i do not understand some of the code in the protocol, would it be possible for me to clarify them with you? Thank you.
HI,
Does anyone has experinece interfacing 8051 microcontroller to a SD card. I working on this project. It would be very helpful, if someone were to offer me some advice. Thank you so much. (by the way i am using AT89C52 and using C to programme).
HI Silvio,
I have solved the Problem. Thank you so so much, It has to do with my 74LS245. As you had mentioned earlier,I have to disable OE before i use the HP Display.Thank you again....I shall continue with my project......
adc0804 + project
Hi,
I have tried to interface ADC0804 and HY62256(S-ram) to AT89C52 microcontroller. The whole idea is to do an A/D conversion using ADC 0804 and than storing the data input to the SRAM. The Value that is stored on the SRAM is displayed on the HP display to check whether the...
HI Silvio,
I have tried what you have suggested, it still does not work. I am attaching my schematic and the code...I dont know whether my hardware is wrong....
I do have another doudt, I have always tied the EA (Pin 31) to high cos i am reading my program from the internal ROM...
8051 timer0
HI,
I am giving you a sample code for delay function using Timer 0 for 50ms,Hope that helps
void delay (void) // Delay function using Timer 0 for 50ms.
{
TMOD &=0xF0;
TMOD |=0x01;
ET0 =0;
TH0 =0x3C;
TL0 =0xB0;
TF0 =0;
TR0 =1;
while(TF0==0);
TR0=0;
}

HI Silvio,
Thanks for your help again, Yup with regards to storing data, i do think it is storing cos the LED switches off after some.
with regards to
It is the first one where *addr++ means :
increment the addr and then store the value of advalue to a cell memory pointed to by...
HI Silvio,
Thanx for pointing out my mistake, i have rectified them and it seems to work. But now i have another problem. I am trying to store the data into the SRAM and also trying to display the value on a display. The display does not seem to work, it always display 0. And another...
