I had tried many delays between reading and writing and between any possible changes that needs delay
but the problem when first time erased the EEPROM and program it with some certain numbers using the programmer
I was able to write to the EEPROM only once
and then when I try to write...
Thnx :)
but realy the problem I have in writing to the EEPROM itself not the communication
it appears that the status register won't be cleared
when i set the write enable it is enabled but the write protection is on and the two block protect bits is also on
after writing 0x00 to the status...
i have fxd the reading and it's working fine with a small problem that the address 2B is FF even though that data in it is not FF...
but i am still cant fix the writting and dnt knw wt to do ?!
plz give me hints if u knw coz i am time limited currently
sorry for not posting the code
here is the code , at the end i want to test if it has saved in the External EEPROM by reading it and puting the data in the Internal EEPROM
#include<pic.h>
__CONFIG(INTIO & WDTDIS & PWRTDIS & MCLRDIS & UNPROTECT & UNPROTECT & BORDIS & IESODIS & FCMDIS);
unsigned...
hello my frnds help is needed...
i am using 16f690 microcontroller and would like to connect it with an External EEPROM using the SPI connection, i have written the program but it is not working i dnt knw what is the problem or hw can i fix it ...
i have done all what the data sheet say's...
hello guyz :smile:
I have a problem with the pic program
I've wrote a program to send a single letter to the PC using the serial port
but the letter keeps printing on the screen???
#include<pic.h>
__CONFIG(INTIO & WDTDIS & PWRTDIS & MCLRDIS & UNPROTECT & UNPROTECT & BORDIS & IESODIS &...
it worked worked but with troubles the data dont stop from being transimted from the microcontroller and recived by the transimtter i have un-enabeled the transmission but still i am getting the data ??! wt to do
Goood news frnd the program worked ... ;) but still some troubles the data doesn't stop from coming (receiving), the microcontroller transmit in a loop and never stop i have un-enabeld the transmition but nothing changed. ??! wt else can i try ?!
no it ddnt we always had problems :( and nw in vb6 the com port is not identified eventhough we have downloaded the driver ??!! i dnt think the problem is with the program it's connection problems.. we have tried sending only or recieving only and nothing is happning
thnx for the help ... i have changed to vb6 coz i've been told it's better for hardware inteferance but having problems with receiving and sending data no i dea y ?
to connect between the microcontroller and vb6 i used UM232R (UART to USB) converter.
hey ... iam trying to connect 16f690 microcontroller through UM232R (UART to USB) converter into vb6, it looks like the data are being sent from the microcontroller but they are not recieved in the vb6 and i cant see them on the form, also i am not able to send to the microcontroller .... hv no...
hi all
i have to connect a microcontroller to a pc through serial port and use VB.net 2008 to receive the data ... and i m stuck neeed hints or a simple program that will receive the data from the microcontroller.... thanks in advance
hello :)
I have to do a mobile communication project using matlab
so I chose to work on zigbee and i'm new to it
I need help in building the model in sinmulink
or if you have any other suggestions for the project:roll:
