Hello, I have a problem that UART1 on LPC2138 is dropping characters.I am communicating with a GPRS modem to send data to a server using AT commands.I am using RTS ,by writing to the U1MCR resgister,switching it OFF in the ISR if 30 characters queue up and ON in the Getch routine when 2 characters remain to be read.This is not AUTO RTS,since LPC2138 does not support it,only LPC2138/01 does. ...

After much digging I found a November, 2004 prelimary LPC2138 User Manual posted here in the Files section. It looks like it's just the same old set of Arm peripherals. But I'm starting on a LPC2138 board design and am feeling a little nervous about any LPC2138-specific "gotcha's" that might make the 2138 a tad different than other LPC2's, and cost

Hi All- I'm currently experiencing a very frustrating issue with the LPC2138 bootloader. I can successfully and reliably use the Philips flash utility to download an image to a blank LPC2138 once and only once. After that, the flash utility is never able to communicate with the LPC2138. I have been monitoring the recent bootloader thread that was resolved by manipulating the watchdog

Hello there - I need to interface LPC2138 with an external device (Coolrunner CPLD), and would like to keep a common crystal for both. For LPC2138, if I keep in osc mode, it is using XTAL1 and XTAL2 as crystal input pins. My question is, if I want to supply a 12 MHz clock from LPC to CPLD, how should I do it?
