Hi friend, I'm trying to communicate two pics(16f877a) using spi of is very greatful if anyone can help me by giving Microc codes and fin diagram.Please give your guidence for success my project. for spi fin diagram, google Internet, and for MicroC code, MicroC Editor has built in library for (...)
Hi, You can use any of the serial communication protocols like spi, UART, One-Wire Interface or I2C(TWI) or parallel communication, ie just connecting one port of master to one port of slave. I suggest using UART, as it can be used over a reasonable distance, requires only two transmission/reception lines and is fairly simple to code. Hope (...)
you can use the pic16f877 and c.i 74ls595 wich is a converter spi, you can use many of this c.i are very interesting
I can not comunicate 2 16f877 in spi mode; Is there any one whit an example working. Tanks in advance.
Here's my version of universal board: all ports on separate 10-pin headers with pull-ups/pull-downs (jumper), integrated max232 and USB connector, DC plug with 7805 and 4 multiplexed spi connectors and an ICSP (RJ12) plug. Board can be powered either from USB, DC plug or ICSP But, there are two design errors to fix: 1. DB9 connector was routed

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 (...)
