... No, I2C have short wires; CAN is very long lines. Rules in Czech: all wires, what is on the conectors must be EMC protect and galvanics isolated, test wawe...
Hi all. I my application, I have a typical need. I am using a LPC2103. I get an interrupt, EXT_INT1, and I go into the ISR. Its an IRQ. Now, in the ISR, I want...
... Now, in the ISR, I want to load the stack with an address of a function, such that when I 'POP' the stack, the address for the next instruction should be...
Hi, I'm using the LPC213X and the PWM controller using PWM2 as a double-edge controlled output. It seems that no matter what I do, as soon as the GPIO pin...
Hi Philip, Am I right in thinking that you want the pin to go directly from <forced high> to <pwm> without a period of <forced low> ? If that is the case, why...
A new UART Baudrate Calculator has been posted on the NXP Standard ICs Website. The calculator allows you to enter in the clock rate, the baudrate and the...
Hello Group, I am using Keil RealView on an LPC2210 target. Recently, I decided to use 16-bit external memory interface on an S29AL016D flash memory chip....
Dear All, I'm planning to use LPC2106 for a new design. My question is how big program could be up-loaded via ISP/IAP. I know that for Atmel SAM7 is...
Hi Brendan. See it goes like this. I want to write some value in 24C64 (EEPROM, which is I2C based) when I get an external interrupt. So when I get the...

Danish, Thanks for the reply. As soon as the PINSEL command executes, the IO line will drop to LOW. When the timer starts on the next instruction, the line...
... Well, with ISP, it is written in small chunks: 256, 512, 1024 or 4096 bytes. It is true that some LPC2000 Flash sectors are 32K in size, but you don't...
A protocol has been defined for memory and register read write with I2C. The protocol has been provisionally named I2C2MEM. Information available at...
... I'm not using Keil, just gcc to configure the external memory controller to use a 16bit bus to a CY7C1041C33 (Cypress) SRAM. All I had to do was program...
... OH! Just a thought, if you have a commercial JTAG unit, they have Flash programming built in. Perhaps you could program the Flash from JTAG, then...
... Yes, I know what you're doing. I had a program on an 8051 which did the same thing, a multiple-task. You are correct in that you would have to do it...
Kai I absolutely understand you frustration. I have been struggling for a couple of days now on writing and reading from USB. My problem now is that on certain...
Hi David! No, I did not recognize any lockups. Did you enable the USB clock (USBCLKEN) as mentioned in a previous post from me? It is very important not to...
We've seen quite a few of these calculators appear over time (I have 4 saved now!). The one problem with all of them is they insist on one particular baudrate,...
Hi, Im using the lpcusb stack on a 2148, and i get the code to compile under crossstudio and when i have it running windows will ask me for the driver and and...
SPI works now. I'm using it in a run to completion style code like this: if ( ! spi_transferring) { sel.select_action = SELECT_ACTION_SEL; ret = ioctl(...
Thanks Brendan, Robert and Tom. Really appreciate your replies. For your information, I have already done what you said, set a flag in the ISR and polled for...
... How long (about) is the low period ?? Can you maybe load the PWM counter with a value so the compare is true ? If necessary, an external gate and GPIO pin...
Hi all, I am using graphic LCD with ARM LPC2106. I have written initialisation code for lcd. but i am facing the problem that sometimes it is getting ...
Hi I was just looking around for Projects where uCLinux has been ported on LPC2378 or the LPC23XX family of Micro\'s. Will appreciate if someone can lead me to...
Hi Philip, The behaviour you describe is not what I expected. (Which is not to say that it is not true...) I don't understand your description ... ^^^^^^^^^^^ ...
Hi Guys, I need to implement Bulk In write endpoint of data as much as 2kbyte reliably.using the VCOM code provided for LPC214x. 1. what is the consideration...
