Hi We're trying to interface a PIC micro to an 8052 micro using the Parallel Slave Port on the PIC. The 8052 can read bytes written to it by the PIC ok, but when the 8052 writes to the PIC, the PIC tends to read what it last wrote and not what the 8052 sent. The voltage levels on the data bus show contention with "half levels" when the PIC and 8052 are opposite states. Is there some...

Hi! For an embedded project I have to implement the md5-algorithm on a 8052 CPU. First I thought it might be a more or less easy task, but after looking a little deeper into the problem I got in touch with a few problems: - 8052 is only a 16 bit processor. Most md5 (reference) implementations are based on 32 biut - For my project I only have 32k of flash memory. If I use one of the ava...

Hi. I am interested in how a program could detect if it is running on an 8052 compatible device, or just 8051. It should be reliable, i e if the device is not 8052 compatible, the test sihould not hang up the device. One idea I have, is to write to the idata space and read back. But then I need to know that NO 8051-non8052-compatible device has the extended, 256 bytes, internal memory. S...

hi, i was wondering how to connect an adc and a dac to a 8025 (DS89C420). do i have to use the two UARTs or it's better to use the "raw" i/o pins? what i'm trying to do is a sort of audio filter: the signal is converted in digital, read by the 8052 (where the fx are applied), and sent to the dac. moreover i'm using BB's PCM1802 as the ADC and PCM1744 as the DAC. the problem is these are all ...

A news bulletin concerning website changes has been freshly posted on my 8052 microcontroller HomePage at: http://members.iinet.net.au/~vanluynm/ Get around to taking a last look at the site in the next 1-month if you can, as it will comprehensively vanish at the end of that period.

Greetings, I'm looking for a basic 4x4 matrix keboard scan routine for the 8052 family of chips. I want to use one port with 1 nibble as outputs and the other as inputs and periodically scan for keypresses. I've done this many times in the past but it's waaaay past and there isn't much need to reinvent the wheel. If someone could point me to a source I'd appreciate it. I looked all over...

I got some 89c51's from a canceled project at work. I'd like to learn about how to make a project myself. I've found BASCOM-51. I've found some LED projects. I'd like to start with BASIC programming, since I don't know C. Is there a windows based development system that I can learn on? I've heard of 8052-BASIC. Is there a way to put the 8052-BASIC in the AT89C51RD Flash? thank you -- ...

I'm working on a senior design project involving an 8052 microcontroller. We currently have a hardware setup from a previous semester's team that has an HD44780-based 16x2 character LCD as the main means to displaying information to the user. The C library we have from the previous team does not compile with what we now have. I would appreciate any information anyone might have on where to fi...

I am tring to interface PS/2 mouse (optical) with a 8052 (AT89S52) microcontroller. From what I get from the internet without adding any extra hardware I cannot interface the mouse directly with the UART (serial port) of the microcontroller (mouse has data and clock lines; uC has RXD, TXD). 1. Are baud rates defined for asynchronous serial communication? What are the common baud rates used ...

Does it even matter? I've been doing the smaller micros (PIC, 8052, etc) in assembler for quite a while now, and I'd like to tinker with some ARM type stuff using C (gcc will be fine). I want to be able to use TCP/IP on the board. Looks like Olimex makes some pretty decent looking dev boards for cheap, but I don't know if I should lean towards the LPC line or the SAM7. What say ye? ...

I'm near the end of a project and would like to learn more about ARM processors for embedded use. I have experience with 8052, 386, HC11, and 6800 derivatives, but nothing with the ARM. Since this is a learning exercise (for now), the requirements are minimal: * Documentation: complete and reasonable well done. * Form factor: don't much care, but easy interface with peripherials nice. ...

Just been handed a possible job that requires a encoder IC to be set up via SPI, about 20 r/w 8 bit registers. I'm going to use a 8052 with a 2 line LCD that's memory mapped, just because I have a couple of boards lying around I'll add a few buttons, but I was wondering if there is any neat way of organising the code (in C ) to play around with the registers while prototyping ( mucking...
