Sorry, wrong cpu written: I think it must be one of the following: LPC2212 / LPC2214 / LPC2292 / LPC2294. Board must have big RAM (where i can execute code, store data), but can have no flash.

The first lot will be run somewhere in September after our Summer vacation. It's same as LPC-H2124 i.e. all ports are available on two connectors but have the extra RAM and Flash on board.

Does anybody have a CAN bit timing value for a 14.745 MHz crystal. The new CAN_All sample from philips_apps is designed for a 12 MHz crystal. Is there a CAN bit rate calculator developed for ARM systems yet. I've seen calculators for 8-bit CAN controllers. Thanks Pauric

If you already have Ashling EVBA7 board you could get an adapter from http://www.adapt- plus.com/products/philips_arm_lpc/prod_philips_arm_lpc.html CA144QFP-J2J3PS --- In , capiman@t... wrote: > Sorry, wrong cpu written: I think it must be one of the following: LPC2212 / > LPC2214 / LPC2292 / LPC2294. > Board must have big RAM (where i can execute code, store data), but can have > no flash. > > Regards, > > Martin > > ----- Original Message ----- > From: <capiman@t...> > To: <> > Sent: Saturday, July 17, 2004 10:14 AM > Subject: [lpc2000] Board with LPC21xx and big RAM ? > > Hello, > > > > does someone know if a Evalboard with a LPC21xx with big RAM exists ? > > Who sells such a thing ?

Has anyone tried using a Wiggler with a USB to Parallel port converter (e.g. startech)? Curt

Hi Pauric, We don't have a CAN bit rate calculator for the LPC2xxx readily available, but if it is just one rate we can help you calculate it... Which rate do you need? Pls. note that 14.745 might limit your choices in available bit rates... Olaf Tutor at ESAcademy www.esacademy.com www.canopen.com

Olaf, I've tried to calculate my own bit timing values for the 14.745 MHz crystal but they are a bit out on the actual baud rate. 125k baud: I got 0x001C001E (for the LPC's CANBTR register) that's a BRP of 30 but that gives 122.875k baud. Is this tolerable? 250k baud: I got 0x001C000F (again for the LPC's CANBTR register) giving a BRP of 15 that gives 245.750k baud. Again is this tolerable. I haven't tried it for any other baud rates. I'll try higher ones to see if the level of error is reduced.

The LPC-SBC2 at http://www.theARMPatch.com may have a bit more on the board than you need, but it definitely has BIG RAM (1MB).

Unfortunately this is a common problem with most CAN controllers. Typically the CAN bit time is divided into time quantas and the length of a time quanta is directly related to the CPU clock. So to achieve bit rates of 1Mbit, 500kbit, 250kbit or 125kbit you typically need "straight" frequencies like 8, 12, 24MHz. That is why several microcontrollers with CAN came up with different or additional clock generators for the other serial interfaces, or at least allow an external clock signal to be used for some of the other serial ports. In short: if you need typical CAN bit rates (for example those used by CANopen), you must choose an "even" frequency. Olaf Tutor at ESAcademy
