This exactly what i was thinking about... but i couldn't find any detail about this. now its more clear.
Yeah i saw that in the datasheet "10,000,000 ERASE/WRITE cycles guaranteed" but it just for testing the SPI. I have buy some 23K256 SRAM to use for my buffer but i made a mistake because i...
I try to understand how to use multiple SPI devices on a PIC18F4550.
I have read on the daisy chain using different chip select all on the same SPI BUS but i cant find any detail on how the data travel...
Example;
If i use a SD card as a data logger using the SPI and a EEPROM as a LCD buffer...
Here my schematic;
The base of the code is the one of romel, i have replaced the lcd code by my lcd code and the spi by the builtin spi from HI-TECH
Here is the main.c
#ifndef MAIN_C
#define MAIN_C
#include <htc.h>
#include <stdio.h>
#include <string.h>
#include "HardwareProfile.h"
#include...
just testing out the CK on PORTB1 and a get a pulsating 5Volt... my PIC is powered by a 5V and my SD slot on a 3.3V.. As i can see the SD card is powered by a ~3V and his clock signal should be at ~3V right? what should i do? a voltage divider with a resistor? or there is an option to set the...
yep. i use HI-TECH V9.63 and i try to find a FATFS working demo for a PIC18F4550 i was having the same error as romel_emperado in his first post. I have edited the PIC18f4550.h by replacing all "DIR" by "DIRT" and my error was gone :)
but my code actually not working... I was wondering now if a...
