I tried to use c0851F060's UART0,but I found there is no output signal from tx0 and rx0(I using crossbar to mapping tx0 rx0 to P_0,P_1),I don't know why?,so can anyone remind me that any passable wrong I colud make?

Hello I am working on a communication programme on PC which should work i the old DOS mode and am using Turbo'c'. The baudrate needed i 115200. How does one set this baud rate (bioscom does not support) the mother board is about three years old so I guess it may be havin 16550. Can any one suggest where I can get documentation on this IC I tried interrupt to receive and it works OK in win2...

Hi all, I am having problems using the Hitachi SH7043 for RS232 communication beyond 38400 Kbps. ( I keep getting Overrun Errors). I suspect that the UART's reliable communication limit is 38400Kbps Any help would be greatly appreciated. Thanks in advance, Vivek

Hi, I am doing the simulation for a system-on-chip project, the processor is PowerPC and in my code I have something like this, int main (void) { print("Hello \r\n"); print("ByeBye --\r\n"); return 0; } But in the simulator I can only see the "\r\n" after "Hello", I can not see it after "ByeBye --". Instead I see all are 0x8, which is BackSpace. I just wonder ...

I want to implement low cost rs485-connected data collection nodes, and need to choose a microcontroller for them that will support baud rates of more than say 400 kbps, preferably up to 1 mbps. I know there are some PIC18Fxxxx's that have an "Advanced UART" that are claimed do this. Other alternatives? - Chris

I have some experience programming in C on microcontrollers. On an upcoming project, I will be outputting data from the micro via UART. Someone else will write a Visual Basic program to read this data and display it on a PC. It will be a while before this program is ready. Before this is done, is there a way I can capture my data and look at it from the PC side, via something like Notepad, fo...

Hi. I have only one available UART on a micro but need to connect two serial devices (chips on the same board). Is there some type of chip that can be used that will accept two serial inputs and then I can use a GPIO pin to switch between the sources? The two serial sources need not be used together (meaning when one is being used, the other is not required). Thanks

I am bringing up my first ARM project (based on LM3S1439) and am looking for some advice. In my particular target application the processor will be communicating with several peripherals via SPI (2) and UART, maintaining a file system, keeping track of time and date as well as performing a lot of GPIO manipulation. The board is also designed with a few external communications ports so that future ...

I'm looking for a low cost solution to connect a TFT LCD at least 7" to the microcontroller by UART/SPI/I2C. I have to show only static graphic with touch operations. FT800 chip looks nice, but unfortunately it only supports a resolution up to 512x512, and 7" TFT has 800x480.

Hi everyone. Has anyone here used Chipcon transciever parts? I'm thinking about using the CC2500 or maybe the CC110 for a project and wanted to find out the pro/cons for these devices. Also, is anyone aware of a part in this class (embedded RF, SPI or UART interface) that can do 1 Mbps? Finally, how good do the PCB screened antennas work for indoor use, near and around computers?...

Hi, I want to connect a GPS Smart antenna SAM LS from u-blox, to the UART of an atmega128 running under 5V. Unfortunately the GPS runs in 3V and has 3V compatible IOs. I set up a 3V regulator already for the power supply. Can someone explain how to build a level shifter from 3V to 5V with a transistor ? (How do I choose it, how to...

I'm just wondering if anyone is aware of any > 100MHz 16 bit or 32 processors that are available in QFP packages? I need lots of GPIO as well as SPI and UART ports. I've looked at a couple but it seems to jump from 50-60 MHz general use processors from the likes Atmel and Freescale to > 200MHz processors on par with PDA types of duties which are way beyond what I really need (and tend to be in

Hi - I was wondering, what microcontrollers are there out there that have FPUs? I'm working with a board that uses an Atmel AT91SAM7X256 (Atmel ARM uC with ARM7TDMI core), and it is perfect except for the lack of a FPU and maybe the max speed of 55Mhz. So what is available as a replacement? Ideally I'd like to see this: 32b FPU SPI (at least one) UART (at least two) TWI CAN timers...

Has anyone here used this chip. Its a USB to UART Bridge with GPIO. I purchased a breakout board from sparkfun but I could not get the drivers to work on W98se or w2k. http://www.sparkfun.com/shop/index.php?shop=1&cart=404139&cat=66& [about half way down the page.] Thanks for any insight. donald

Hey, I am trying to link the 5V serial port on my ADuC831 (8051) to the 3.3V serial port on my Analog Devices DSP board. Transmission is one way only (5V -> 3.3V). I have no idea what to do to drop the voltage. I read somewhere that it should simply be a case of adding a series resistor, the value of which could be calculated by finding out the max current from the data sheets o

Hi, for a low-cost design I need a small 8-bit microcontroller (1-2k Flash will do) and now the question is whether I need to plan for an external resonator or an internal oscillator is good enough. My application will have to communicate through a serial interface to the outside world. I don't know yet if that's going to be a UART or SPI or I2C, could be different for some of our customer...
