Hi, I am a newbie to the board but I have tried my best to find the answer to my question before posting for help. I am using a QuickStart LPC2106 board with a 14.7456 crystal. I want to be able to accept data from the PC on UART0 and command a PTZ camera using UART1. UART0 is working just great. The camera requires 9600 bps and I am configuring PINSEL0 with the following code: //i...

Hi. Is there another way to send the LPC2106 into power down mode, other than writing in the registers? In other words, can the processor be sent into power down mode by an external event (PIN, insufficient power, etc.)? In advance, thanks. -- Emmanuel Viollet Software engineer Webdyn e-mail : E...@webdyn.com Tel : +33 (0)1 39 04 29 55

Hi Folks, I've got a problem with an LPC2106 uC at the moment that I'm really struggling with. When I power up the board (or press the reset button) I get a stream of mostly garbage from TXD0 lasting several seconds then it goes silent. Sending a '?' to RXD0 sometimes yields more garbage back, but mostly does nothing. After this stream of data the line doesn't always return to idling high (a...

Hi LPC group, I have several copies of lpc2106/01 (new silicon revision) - and for a challenging project in high-speed information processing I just can not get my code to work sufficiently fast at 60MHz. So I started running the chips faster (overclocking). A 16MHz external crystal allows 64MHz, 80MHz, or 90MHz. In my current design they do very well at **all** of these speeds (includin...
