    LCD (16x2 @ 8bit) C programming

    lcd programming in c Hello All, I wrote ASM code for huge project, but it still has few bugs. So I'll try to program it again with C language. Reazon is not working I2C communication between two PICs (Í disscuss with that problem earlier in here). Maybe it is easier with C ?. I use 8 bit...

    Connecting two PIC18Fxxxx microcontrollers together with I2C

    i2c between to 2 pic I did have same problems. So I can't help. I think microchip's i2c hardware is not so easy (with assembler). I worked almost month with the I2c problems. Today I replace communication to SPI or similar software based data communication. Reazon is that I do not have any...

    Connecting two PIC18Fxxxx microcontrollers together with I2C

    comunication two pics i2c Hello, I made PCB for the mainboard about 1½ years ago. I impelemded some PORTC pins to extra connector and TX and RX pins to controlling second controller. Now I need that extra connector to use with new board. Unfortunately there is no available RX/TX pins...

    Connecting two PIC18Fxxxx microcontrollers together with I2C

    ssp1buf I am writing software for gaming project. (Flip a coin machine). For an example, i made one game electronics few years ago: **broken link removed** That machine has two PIC microcontollers, second pic executes payouts and main pic sends commands to second pic by USART (RS232)...

    Connecting two PIC18Fxxxx microcontrollers together with I2C

    i2c communication between two microcontrollers Hello, I am starting programming programs whitch communicate between two PIC18F6520. (It is possible to use SPI also, but what is maximum cable lenght between SPI devices?) The protocol should be very easy. It will be send only 2-4 bytes at one...
