I'm working on OKI 431 microcontroller. This is 8-bit microcontroller. We don't like to have any floating point operation to be performed in our project so we've eliminated all floating point operations and converted them into integer operations in some way. But we cannot eliminate one floating point operation because optimizing the calc...
What happens if you disable an interrupt inside that interrupt's ISR? For example, if I am transmitting data over USART from a buffer and that buffer runs out of data then I want to stop transmitting temporarily, so after sending the last byte in the buffer, I disable the interrupt. (This is on a PIC18F4580) The datasheet for the PIC18...
Hi! All I've a Good Command over C++, But I've never done anything anything on device programming. I've some basic understanding on Digital Logic Design. But I am complete Noob in Electronics. Currently I am getting huge interest on microcontroller Programming. Where To Start ? I don't think one really needs to have huge amount of know...
I have used and like the Atmel ATMEGA and ATTINY series microcontrollers, and think them quite good. One thing I am not terribly fond of though is the fact that they (and Microchip PIC uC family also) are all Harvard machines, meaning I can't really put external memory to use or execute out of RAM, only the flash. While there are obviou...
I would like to control an RC model via USB from my computer. I don't need a real radio control, so controlling the servos directly through cables is sufficitent (yes, there will be cables between the model and the controlling unit). I thought I would build some microcontroller-based device which would be connected to the computer via US...

Hi, I was given a Sanyo #B00224 4 wire stepper motor, and for the life of me cannot determine the drive sequence, e.g. what order to power the coils and in which direction. As far as I can tell it is a bi polar stepper motor and should be drive-able with: Winding 1a 1100110011001100110011001 Winding 1b 0011001100110011001100110 W...

Hello all, I am trying to program Blinky program from Keil complier to P89LPC936 microcontroller through a universal programmer(SuperPro). But the microcontroller is not running. But when i write a simple program in assambly and program the same hardware it works fine. Please I need help regarding it where i am doing wrong. Here is cod...
This is related with microcontrollers but thought to post it here because it is a problem with algorithms and data types and not with any hardware stuff. I'll explain the problem so that someone that doesn't have any hardware knowledge can still participate :) In Microcontroller there is an Analog to Digital converter with 10 bi...
I have a LPC1768 microcontroler that I am trying to use to read a joystick. I am using the usblite sample code provided with the microcontroller to get a head start. It is meant for a flash drive but from what I have read the enumeration is the same no matter what the device is. However when I connect any hid device, it fails to write to...
Hello all, I want to make an application where PIC18F4550 send its internal eeprom data to the pc through usb.

Hi stackoverflow, First of all, I wanted to thank the community. You've been of great support lately ! Usually i don't even need to ask the questions because they're already there. Now i have an issue that's not directly related to code but programming itself. I'm working with a FTDI Chip and C# programming a communication protocol in ...
