People, I'm reading DS of this device, and is not clear for me if the pins are 5V tolerant just in I/O functions, or if in second functions, like CAN and UART this remains tolerants. Thks, leomecma

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

hi, everyone, Is there a kind of MCU that includes at least one on-chip CAN transceiver(like LPC11c24), plus the following features? 32-bit ARM7 architecture, 128K flash, 16k SRAM, two SPI interfaces, RTC, UART, IAP, watchdog. It would be best if it contains one ethernet port, and be able to run uclinux. ------------------------------------

Hello, Can anyone point me at a PC utility to program the LPC11Cxx parts via CAN (and optionally UART) using the built-in ISP bootloader? Only the CAN port is accessible in my hardware, so I would like to be able to use this as a fallback if the device somehow gets bricked during IAP. Thanks, Kevin. ------------------------------------

I think I may be missing something stupid, but can anyone help me? I am tring to write to UART0, but it doesn't seem to work. I am trying to write a software buffer to help out the one byte hardware buffer. Specifically I am using the LPC 2294. Below is my code. I am us

Hi Folks, I am very new to the lpc2xxx family (although I am competent at PICs) so I am looking at what other people do with the peripherals. My current line of investigation is the UARTs, which are described as "550-compatible". Of course I want everything i.e. interrupt-driven and externally-buffered serial input and output, but I don't seem to be

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. (hence going back to the vUAR0RX function) -so my questi...

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...

Hello, I use a LPC2138 microcontroller with a 25MHz xtal. I set the pll multiplier at 2 and de devider =2 (in the startup code of KEIL). This gives 50MHZ CPU clock. This works out fine, in determining the speed for the UART (baud rate is ok). But when I run a very small program, toggeling the LED's, I only get 16 MIPS out of the controller. The

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!

Hello all, I am trying to develop a board similar to MBC2300 for LPC2368 actually I need only UART and ethernet module. This is the first time my interaction with ethernet. I tried the same connections for DP83848 as provided in MCB2300 Schematic but unfortunately it is not working out me and I am not able to figure out the problem. Also I am not using any Ferrite Bead - SMD ( L) as ...

Hi Alex, and everyone else, Working with a LPC1114 I encountered the same problem. After having programmed the uC several times, it suddenly started failing to communicate through SWD. I know the uC works because it still responds to commands sent through UART, leds blink, etc. And I know ULINK2 works because I tried it with other boards. Did you find a solution to this problem? I've ...

Hello Group, I am trying to get this chip to work on my Phytec board with lpc2220 on it. So far, I have found code samples online that are compatible with the 8051 system. Has anyone used this chip on the LPC or ARM environment who can provide me sample code to make my life easy? Tips, comments, curses welcome. Thanks. Karim.

Hi, I am very new to ARM processors, and as a first simple task I just want to dump something a pc can read. I am using Keil uVision 3.5 with RealView compiler. The processor is a LPC2103, XTAL 19.6608, CCLK 58.9824, M 3, P 2. I am trying to dump Hello World! to UART0 but nothing. I calculated U0DLL based on the Phillips application note AN10369. Any Ideas?
