Hi, I am trying to read/write data at any sector of CF with a 8051 in Language. I don't understand very well how CF works and i need to complete m project very quickly. I would like to know if there is anybody that could give some help ( code, for example) to communicate Compact Flash with 8051 at True ID Mode. Thank you very much for all attention and help Best Regards, Tiago M...

I'm in problems!! please Help Me!!! I'm interfacing an 8051 from Atmel (AT89s8252) with an USB to serial converter from FTDI (FT232BM). The FT232BM is Bus Powered and the 8051 is powered through the BUS too. The interfacing i use is simply through the UART of 8051 directly to the TXD and RXD pins of FT232BM. Just for testing, I've programmed the 8051 t osend a byte to the port conti...

Respected Experts, I am Ravikumar.N, working on 8051 microcontroller. I have an issue regarding the pulses of unknown frequency. I am equipped with the following things: 1) I have an 8051 based development baord. 2)I have an unknown frequency source. My Purpose: I want to measure the pulse width of the unknown frequency that will be fed to 8051....

Lots of companies have 8051 compatible chips... Atmel, Dallas, Philips, Siemens... Is the 8051 CPU public domain, which could explain why so many guys chose to use it? Or do these guys still have to pay royalties to Intel? Thanks.

Hi, I have a problem with a timer interrupt on a CC1110 (8051 with wireless interface) that I have been staring at for an hour with no success. 8051 is not a strength of mine so I would appreciate your comments - Given the (very!) simple program: char x; int main( void ) { char c = 0; ____IEN0 &= ~pdBIT_7; ____SetClockSource(); // Setup processor clock. ____vInitTimer3( 100...

Hi, I've been developing some 8051 based projects and the programming is getting a bit taxing in assembly language. I'm a bit familiar with C and was thinking of using that to program the uC. Does anyone have any good websites where I can find some in depth information on starting off programming the 8051 in C? Thanks a lot. - Al

I'm working on my final year project. I have to receive voice(8KHz and 8-bit is enough) with an ADC and send it to a computer via Internet. So I have to choose a microcontroller. The embedded system that I want to design includes: 1. ADC and DAC 2. Network Controller 3. Graphical LCD *I have experience with 8051. Do you think 8051 is enough for this project? I have doubt about required...

One of the most common I receive - "Can you help me run Linux on my 8051", or more often than not "Can u plz give me source code for Linux on my 8051, waiting your reply. Urgent. Thx". I've just been looking at the search stats for last month on the FreeRTOS.org site, and believe it or not, the number one search with more than 50 entries (so more than once a day!) is "Linux 8051". I wo...

Hallo, I'm doing a project (for a university exam) based on a 8051 microcontroller that comands with at commands a siemens cellular using 8051 serial port. Siemens cellular is connected to 8051 through its data cable,but: 1)if i send at commands to cellular with hyper terminal,it' ok 2)if i send at commands from micro to pc,it's ok 3)if i send at commands from micro to cellular,it doesn't r...

I have project for school where we are using the Cygnal 8051 mircocontroller to capture acceleration. My part of the project is to take the data stored in memory and use MatLab to produce graphs and such. My question is where do i get started... how can i directly interface the 8051 with Matlab.

I am working on an 8051 project. The code size has grown very large. I am currently using code banking which makes compiling and linking of the code very time consuming. For example to do a re-build take about 2+ minutes using the Keil Compiler. I know that some people have used Visual C/C++ 6.0 to do 8051 development (these are systems where there is almost no assembly except for the startup...

Hello I am new to the 8051 compatible controller. I am used to PIC as well as Renesas and using C. The 8051 does not have a "Port Direction" to set. I have some questions regarding this: - How to set it as input? I read something of writing 1 to the latch. However, this is as using it as output and set it. I don't get its function. - How to set it as output correctly? - There is a d...
