I would like to have a code that can run 2 hall current clicks at the same time on the same board and be able to display it on the 2x16 LCD. Below is the code I have written but have been stuck since. Please correct or guide me into the right coding.
//Lcd module connections
sbit LCD_RS at LATB4_bit;
sbit LCD_EN at LATB5_bit;

sbit LCD_D7 at LATB3_bit;
sbit LCD_RS_Direction at TRISB4_bit;
sbit LCD_EN_Direction at TRISB5_bit;
sbit LCD_D4_Direction at TRISB0_bit;
sbit LCD_D5_Direction at TRISB1_bit;
sbit LCD_D6_Direction at TRISB2_bit;
sbit LCD_D7_Direction at TRISB3_bit;
// End LCD module connections

I am doing a project that requires two NRF24L01 to communicate using two PIC16F877A . One NRF24l01 is a PTX and the other a PRX. I am using Enhanced Shockburst . Please , some should help.T

need pic16f887 interface with with TRIAC interface with zero cross detection algorithm without external interrupt

Hi,
I am using STM32F4 Discovery Board. I am facing issue to communicate 2 boards with each other. Can anyone share code to communicate the boards with each other. There is no concern to use whether SPI, I2C or UART.
Looking forward to your expert solution.
Regards,
Nelson Alexander

I would very much appreciate it if someone could please generate some example code and Library for the nRF C or T Click board in MikroBasic for AVR? I want to develop a wireless hand control for my CNC machnie and the nRF24L01P chip would be great in that application.
Thank you,
Neal Cooper
