I need a stereo I2S ADC. Digilent makes what looks like a nice development board: http://store.digilentinc.com/pmod-i2s-stereo-audio-output/ ...but I'd love to have a click board. I second that but I2S standard requires additional pins which does not exists on click-board socket. My main interest i...

Any plans for FT81x and STM32F7 series? I'm using FT800 ConnectEVE 4.3" board but for my project I need bigger "intelligent" screen with, at least, 800x480 resolution. FT81x series is almost ideal for my project. Also new STM32 Cortex M7 series is pin compatible with old M4, so cost for development ...

USB throughput is shared among devices attached to USB controller (modern PC control logic have more than one controller). For normal use you do not need to worry about this characteristics.

If you run your program trough software simulator observe how LCD commands are slow: Lcd_Cmd(_LCD_CLEAR); // 5.51mS Lcd_Out(1,10,txt); // 5.69mS Alphanumeric LCD displays are very slow devices. With only one line you are further slowed down by half HID speed: Delay_ms(2); // small delta ! (minimum t...

You can't change HID communication protocol by changing PIC file descriptor. HID is interrupt transfer type and for bulk or isochronous transfer types you need complete USB stack with supported functions. For example: go to: http://dangerousprototypes.com/docs/index.php?title=Open_source_USB_echo_de...

Start from MikroE USB HID example and simple add A/D conversion.

Did you consider life time for encoder in this application (only 15K cycles!)? This type encoder is for manual input by human hand. Better to use optical infra red transmiter/receiver and transparent disk with printed coding lines. To answer your question: first check output pin for direction (risin...

From MikroC help file: 1: interrupt mode: void interrupt() { USB_Interrupt_Proc(); } 2. polling mode: while(1) { USB_Polling_Proc(); kk = HID_Read(); if (kk != 0) { // do something here } } Once your code enter while loop while(1){.....} never read from USB or code is not complete.Error on PC side p...

What exactly is problem with your program?Hardware connection,
PIC configuration, PIC<-->PC connection or something else?
Without complete project it's very hard to tell anything useful.
MikroC example files are very good for beginners.

Does check boxes "Append CR" or "Append LF" help you?

- 18F2550 do not have port D and E( TRISD,TRISE,LATD and LATE registers do not exists). - MCU clock should be 48MHz(CPU core works on 48MHz, USB uses 96MHz).If necessary change appropriate configuration registers to meet your board design(critical is crystal configuration-search forum messages for d...

From USB library function list you can see correct interrupt handler name: USB_Interrupt_Proc You interrupt routine should be: void interrupt(){ USB_Interrupt_Proc(); // USB servicing is done inside the interrupt } What is you project settings(CPU,freq,fuses...)?Did you choose 18F2550 as uC type?Als...

First you must determine that project configuration works!Forget USB and connect LED diode on free uC pin(do not forget to configure PORTx.Fy as output).Then with various Delay_ms values turn on/off LED in desired intervals(0.5s-1s is detectable with eyes, for anything less use scope). For 4MHz crys...

Sorry, but I do not have Proteus software.I'm using only
real hardware for development/debug.
Is code I posted previous works in Proteus?
