I use labview 8.5.1 to communicate with microcontroler (PIC 18F4550).I programmed PIC by MirkoC, use HID Library for USB communication. I also use NI_VISA Driver wizard for USB on my PIC, and the labview had recognized it. When i communcate Labview with PIC by USB_RAW, I can write data form Labview to PIC but can't read data from PIC to Labview. Could u help me to solve the problem. Thanks all! I also use temple of Find example in labview usb raw but it still like it. T_T It's the first time i post in forum so sorry how can insert image? maybe my E not good! Thanks again! This is the code C for microcontroler: unsigned char Reader[64], Writer[64];void interrupt(){ HID_InterruptProc(); // Keep alive TMR0L = 100; // Re-load TMR0L INTCON.TMR0IF = 0; // Re-enable TMR0 interrupts}//=============================================================void main(){ ADCON1 = 0; // Set inputs as analog, Ref=+5V ADCON2 = 0xA6; TRISA = 0xFF; // Set PORT A as inputs INTCON = 0; INTCON2 = 0xF5; INTCON3 = 0xC0; RCON.IPEN = 0; PIE1 = 0; PIE2 = 0; PIR1 = 0; PIR2 = 0; T0CON = 0x47; // Prescaler = 256 TMR0L = 100; // Timer count is 256-156 = 100 INTCON.TMR0IE = 1; // Enable T0IE T0CON.TMR0ON = 1; // Turn Timer 0 ON INTCON = 0xE0; // Enable interrupts Hid_Enable(&Reader, &Writer); Lcd_Config(&PORTD,7,5,6,1,2,3,4); // SETUP CHO LCD Lcd_Cmd(LCD_CLEAR); // Clear display Lcd_Cmd(LCD_CURSOR_OFF); // Cursor off Lcd_Out(1,1,"WRITE DATA TO LABVIEW");//============================================================= while(1) { Writer[0] = 'A'; Writer[1] = 'B'; Writer[2] = 'C'; Hid_Write(&Writer,3); }Hid_Disable();} another code include form this program #include "Definit.h"#include "VARs.h"unsigned char const HID_INPUT_REPORT_BYTES = 3;unsigned char const HID_OUTPUT_REPORT_BYTES = 3;unsigned char const HID_FEATURE_REPORT_BYTES = 2;unsigned char const NUM_ENDPOINTS = 2;unsigned char const ConfigDescr_wTotalLength = USB_CONFIG_DESCRIPTOR_LEN + USB_INTERF_DESCRIPTOR_LEN + USB_HID_DESCRIPTOR_LEN + (NUM_ENDPOINTS * USB_ENDP_DESCRIPTOR_LEN);unsigned char const HID_ReportDesc_len = 47;unsigned char const Low_HID_ReportDesc_len = HID_ReportDesc_len;unsigned char const High_HID_ReportDesc_len = HID_ReportDesc_len >> 8;unsigned char const Low_HID_PACKET_SIZE = HID_PACKET_SIZE;unsigned char const High_HID_PACKET_SIZE = HID_PACKET_SIZE >> 8;unsigned char const DescTables[USB_DEVICE_DESCRIPTOR_ALL_LEN*2] = {// Device Descriptor USB_DEVICE_DESCRIPTOR_LEN, 0, // bLength -
