Re: C version of BASICchip

According to the NXP web site, Mouser has 3500 or so in stock We haven't ported the Csample.c code to the 1114 yet, right now we are more focused on the BASIC side. The IO ports of the 1114 are the old ARM style with address mapping selecting bits, so the defines using the NXP style port will have t...

Re: C version of BASICchip

The DIP version of the LPC1114 is listed as non stock item at digikey. I'll check around. I tried to use MakeItC by selecting LPC1114 under Options, and Build HEX on an old sample #include "constants.h" #include "coridium.h" // this is required #include "cor_init.h" // sets up UARTs -- could toss th...

Re: C version of BASICchip

The short answer is no.

But you can buy the LPC1114 from Digikey, the same chip.

Our MakeItC tools supports that part.

Re: SPI performance

Got this working now, thanks for your reply. This is definitely the way to go
for SPI stuff. It is so fast, I have to lower the clock speed to the peripherals
so as not to exceed their specifications.

Re: BASIC compiler update

Version 8.16c of the compiler is attached here Per user request, the ADDRESSOF operator accepts CONST arrays. In order to support that, CONST arrays now allow multiple lines so Code: Select all const multi = {0,&H11,&H22,&H33 ,&H44,&H55,&H66, &H77,&H88,&H99 } if *(addressof multi +(9<<2)) = multi(9)...

Re: SPI performance

Generally the way SPI works is you have a master and one or more slaves. The master provides the clocks. The master will select a device via the chip select and sends/clocks out the command while the slave is sending back status or a response to the command in sync with the master clock. So data is ...

Re: SPI performance

Does anyone have any experience with using the SPI handler that is built in to the LPC1756(SuperPro)? I am trying to use 3 or more SPI devices that each have their own chip select, but share SCK, MISO, MOSI signals. I am confused about the whole Master/Slave thing. In the case of writing a value to ...

Re: SPI performance

Thank you! The throughput is now more than twice as fast. Good enough for most
things I want to do. Still not fast enough for some things however. I am very
interested in learning more about the LPC1756 internal SPI handler. I will start
a new thread about it.
