Hi, I have an external device(board) which gives data at the rate of 240 bytes = per second. This data is sent at a baud rate of 4800 baud, 8 bits, 1 stop b= it, and no parity. I need to collect this data into my lpc2138 board and print it to hyperterm= inal via UART0 To print some sample string from the lpc2138 board to the hyperterminal via= UART0, I had to set the baud rate to 9600 (i...

Hi! Sorry if this is a stupid question, but I haven't found any good info about the UART levels so I better ask! Need to connect a LPC2138 to a Maxim (Dallas) DS2480B which is on 5V. Can they talk as it is or do I need a 3.3 to 5V buffer between? Thanks for any help! Cheers /Johan

Hi All, I am seeking clarification of the SPI slave operation for the LPC2138 When an LPC2138 is configured as a slave. Please assume the SPI control register has been configured correctly for slave eg: bit2 BitEnable= 0 (SPI set to 8bit size) bit3 CPHA (set same as master) bit4 CPOL (set same as master) bit5 MSTR = 0 (set as slave) bit6 LSBF (set same as master) b

Hi, I'd like to measure the performance of some code I'm using, but this doesn't seem very easy to do with the LPC2138. (using freeRTOS and Rowley). In windows I'd use QueryPerformanceCounter() to get a time stamp before and after. Is there an way to do this with the LPC? Or do I need to set up a timer interrupt every 1?s or something to increment a counter? Thanks.

Hello All, I have not used any of the LPCxxx devices before. I am considering using an LPC2138 in an application which must read data from an ADS1271 24bit A/D using an SPI interface. In looking at the SSP specification for the LPC2138, it can handle a m

Been working with LPC2138 with IAR just fine. Trying to move to smaller LPC2131. When I download the same app it won't run to main. Anybody do this yet? I think I'm looking for the equivalent LPC2138.i79 and iolpc2138.ddf (device description file) for the 2131. Anything else? Thanks, Jeff

Hello, I am new at LPC2000. I have downloaded eval version of KEIL =B5vision3. I will have to=20 develop an application with LPC2138. After studying examples, I am trying to create a simple project that=20 displays a character on serial 2 of the simulator (This is very=20 close to the "Hello" example). The program should display a single character once only. Here is the code (very simple...

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

Hi all, We have been trying to use the SSP controller on the LPC2148 (master) and LPC2138 (slave) as SPI. The hardware design is such that LPC2148 and LPC2138 are connected over the SSP interface. There are some sensors connected to the LPC2138 and the LPC2148 has to read these sensor values over SPI. Typically while developing the driver for any interface you would have t...

I'm working on a design with an LPC2148. However, the LPC2148 has a long lead-time in the US. So I'm going to use a LPC2138 until the LPC2148 is ready. The obvious difference is the loss of the USB interface. The rest of the device appears to be electrically and software wise the same. (The LPC2138 does have two 10-bit DACs instead of one on the LPC2148). Any other problems or issues ...

For a hobby project I'm trying to use the LPC2138 LQFP-64 package on a 2-layer board with most of the pins connected. Has anyone ever done a layout on a 2-layer board in Eagle CAD? I'm wondering what settings you use to successfully lay it out and get it routed. Thanks

If anyone has successfully used a 32 KHz crystal with the LPC2138, please explain how to connect the crystal. I saw an example on the Keil eval board where a resistor was connected in series with the crystal. I don't understand how that circuit operates.
