Do you have any wifi adapter module or datasheet? The interfacing depends on what communication to use. UART, spi, I2C. PIC16f877A and PIC16F887 is commonly used, that enough to use UART, spi or I2C.
Dear all I m trying to communicate two 16f877 PICs with spi protocol. And USART is used to display the received data from the slave. But my program is not working. I used variable Y=7 in master and send it to slave and then read it from USART. here is my code. Master // code for spi master void main() { trisc.f3=0;
hello guys , can anyone help in this ?? i want to connect a 16f877 pic to a bluetooth circuit.. all what i need is to transmit data through bluetooth ,, it will be an analog signal and the 16f877 will convert it to digital and send it via bluetooth
spi Communication between two pic 16f877
Hi, The first code is for the slave, ie receiver. The second is for the master, ie transmitter. Data is sent from the master to slave (Tx to Rx/Transmitter to Receiver) via 2 data lines (it can be sent from Rx to Tx if required as well). You need the 1st code for one 16f877, the 2nd for another. Be careful, you specified 16f877, there's another 16

I am new person to this,any one know the circuit diagram,coding for LED Moving message (permanent)from PIC 16f877.pls help me
I can not comunicate 2 16f877 in spi mode; Is there any one whit an example working. Tanks in advance.
16f877 Proto board in Proteus
Hi, my buddy and I are embarking on a small project that includes the demonstration of the spi interfacing capability of the 16f877. I fully appreciate if you have a sample code to share that sends 2 bytes in succession via spi. Thank you! Added after 38 minutes: Oh I'm using HITECH C-Compiler....
You might also note that 16f877(a) has 8 times the codespace of 16F84. Additional hardware present at 16f877(a): Timers, spi, I2C, Capture, Compare, PWM ,Voltage Reference Module ... best regards
I am afraid you can not extend the code memory of a PIC 16f877. You could for example if you have lots of strings in your program put these strings in an external eeprom which can be acessed via I2C or spi bus. You would have to get the string whenever it is required from external EEPROM. I have no idea if your application allows this. Anothe
