I am using the LPC2368 and have reproduced this problem several times: In my application, there is a serial console for debugging on UART0. The application is working normally, periodically sending a status message out TXD0 when suddenly, often in the middle of a message, no more characters come out TXD0. My board has two interfaces (UART0 and an RF interface) so I'm able to query it via the ...

Hi everyone, I am using an LPC2103, compiler IAR EW. While it is easy to get the polled version of UART0 communication to work, I can't get the interrupt based version to work. Can anyone point me to an example on how to initialize a simple interrupt based communication via UART0/1 using IAR EW for an LPC 2103? Or froma similar controller? Thanks a lot, Tappo ----------------------...

Hi, I am using local IDE for lpc2138 in which there is no facility to know how much flsh has been used by our hex file which is loaded in controller through uart0.I am not using jtag debugging, i am just using uart0 for programming and debugging. But I want to know how much flah memory has been occupied in controller flash memory and how much is left. Please tell me how to calculate the...

I am running the lpc2148 at a low clock speed of 12 mhz to reduce power usage. This is working, the power consumption is down and a light blinks at the correct rate. for each speed I reset the Uart0 parameters to take the pclk into account (code below) the PLL_int(code below) sets processor to 12mhz(slow). At 60mhz Everything is working fine fine and I can read the output debug text without...

can someone help me, I am confused by the datasheet and by what I appear to be getting when setting up the clocks. I am using FreeRTOS. Basically I have some simple code that just flashes an LED and I am now trying to get UART0 up and running but the baudrate is wrong. I think this is because CCLK is not what I think it is. My main XTAL is 4Mhz and I will need to use the USB so luckily...

Hi Everybody , First of all , Merry Christams and I hope a happy new year for everybody. May be already answered but I couldn't find it . I tried to read data from UART0 by initializing exactly based around Insider Guide book from Hitex . I could not receive data by Hyperterminal . After checking all parameters , I used Oscilloscope and I had serial

Hello, I have sent posted to the group yesterday (seems to not have worked first time around) - so if repeat please discard Im having trouble with my UART functions, the send seems to be working fine but when receive the buffer does not seem to be empty and is resent as if there was a interrupt triggered every time there is a send.

I have a requirement for 3 RS232 links to my LPC2148. I have run one directly to UART0. The others (for connecting a PC and a modem) I have input into a 3V CPLD and am doing the switching in there to UART1. However, I didn't take into account the signal differences. I was using a Linear LT1382 between the PC and the CPLD, but that won't work because the LT is a 5V TTL out and the CPLD ca...

I've spent a lot of time trying to get this UART Interrupt to work. Not enough I suppose. What have I missed? This is written for the OLIMEX 2148 compiles and runs under GCC and uses the Phillips std LPC214x.h I hope this will be useful to others who have tried and failed! Thanks for your help!
