Hello Everyone,
I have this questions particularly from someone that already use the chip MCP23S17 and how to program it with Mikro C PRO using Port_Expander Library with PIC18F4550. I see some sample codes with circuit diagram in Mikro C PRO and I manage to test it and it works, my Question is...
Hi, I'm working with my project using PIC18F4550, my goal is to expand my I/O ports so I guess I need a Port Expander like MCP23S17 and connect my PIC18F4550 with USB and the PC. My first plan is to use the USART(RS232 Serial Communication to PC) but I see a little bit details of PIC18F4550's...
Hello,
Can anyone have this idea about using 2 Port Expander MCP23S17 and PIC16F877A? I'm using MikroC Pro and I see some sample codes in the library of SPI and Port Expander and I've tested it but the problem is the sample uses 1 Port Expander only and I need 3. Thanks in advance
Hello DineshSL, I need some help in using PIC16F877A-SPI-MCP23S17.... About what you said at your reply, YES, I'm planning to use MCP23S17 as a regular PORT like PORTA and other PORTS that can use either INPUT/OUTPUT in PIC16F877A... Can you give at least a Sample Code in C about Setting Up...
Hello Magnatron, I have a friend that shows me a sample of SPI communication using 1 Master and 1 Slave. So I'm sure that I learn a little bit about some setting of SPI into MCU but I know that it's not enough just to know the settings. Can you give me at least a simple code for my project using...
Hello, I'm not familiar about some special functions of SPI like...

I read some forums about SPI and I find it very difficult to understand. HAHAHAHAHA...
I'm a newbie in MCU's ability.
Look at this thread.....

Hello Everyone, I have a question about Microcontrollers ability about sending and receiving data using I/O Ports only. My goal is to keep a synchronous sending and also receiving a data from MCU1 to MCU2. The logic is like this.................

Hi there,
I have problems in configuring my MCU as Input and also Output in my simple project. My goal on my program is like example, when RA0 of PORTA is toggled, all PORTB will blink ON-OFF, if I toggle RB0 of PORTB, all PORTC will blink ON-OFF, and if I toggle RC0, all PORTD will blink...
Hello Everyone, I have questions about Microcontrollers. So lets start with...
1. How to connect a 2 PIC16F877A using UART?
2. Is there a need of MAX232 to execute this? like a bridge for 2 MCU's??
3. I'm not sure if my codes are correct...I'm using MikroC Pro and ISIS for simulations.
I'm...
Hello Brian,
What do you mean by "use the TRIS Registers in the PIC rather than the Port Drivers to control the connecting wires"
and the "wired-OR"? Did you the second attachment that I show? Is it Possible?
About the post earlier about RS485, can I use that type of protocol in my project...
