I want to interface pendrive to PIC24FJ256DA210. I want to read text file from PenDrive.
We are using MicroC PRO for DsPic compiler. I have ready code for PIC 24FJ256GB110 which is provided by Micro Electronica.
I have converted it for PIC24FJ256DA210. But not getting proper output , means my pendrive is not getting detected.
Hardware is already tested for HID application (USB Key Board). I am using same hardware for this application.

Have you planned to develop code for PIC or PIC32 for sensor LSM9DS1? How different will be from the existence code for AVR and ARM?

Dear members I have a problem, I have prepared the code of GSM CONTROLLING APPLIANCES THROUGH SMS and when I compile it no any error comes after compiling and when i tested it on proteus using PIC16F877A all lights are turned on initially and always remain on until i stopped a simulation. Any one who can collect my code please can help me.. Below it's my code the code was compiled in MikroC for PIC.

Respected Sir/Madam
I have recently purchased Linefollower click from you, but i don't get the library for mikrobasic version, in your library it is only in mikroc version, can you please provide me the library for mikrobasic version.
Thanks & regards

The university has a custom microcontroller that is to be programmed. (It is actually only an implementation, running on top of a Xilinx Spartan-3A FPGA, but for all purposes at hand, it works as an MCU.) It has its own architecture and list of instructions which does not equal any real-life MCU available in the software.
How difficult would it be to add the architecture to one of your software (such as mikroBasic)? Documentation is available - I certainly could write an interpreter for it (I did...), but not an (optimizing) compiler. Could this be done by me? If not, by you? I looked at the data that mikroBasic stores about various devices and it looks like something that's not meant to be modified by the end user.
Thank you in advance
P Sisak
