Re: Documentation, broken link

We rely on the many eyes looking over our shoulder at the documentation. So keep us honest and keep letting us know about broken links, misspelling, bad grammar, or wrong info.

thanks in advance.

Re: new website

I'm not sure what kind of browser you are using, but initially read as a showcase of what we have done for people, seems like you were looking at https://www.coridium.us/coridium/other/consult Consulting not https://www.coridium.us/coridium/shop/boards Boards which has all the current boards for sal...

Re: USB vs. UART communication

When you get to 95 feet, simple TTL might not cut it, too noisy.

But RS-485 differential transceivers would handle it and more.

Re: BT/tclterm function

That button starts out as RESTART when you load BASICtools (BT). At that point it will launch a program previously saved in the ARM. If you choose a program to compile it will switch to RUN, which will compile and load and run the program. It then reverts to RESTART which will again restart the prog...

Re: Multi-tasking

Not seeing that here with the stock Multitask example. But looks like another interrupt active, though I am surprise it would act quite like that.

Re: Simple Benchmarks

Got a couple micromites, as I was curious about performance on those interpreters. 48 MHz PIC32MX170F256B which according to Coremark are a bit faster than the same MHz ARM Cortex M0. float test -- 23.606 seconds integer test -- 81.992 seconds While it a cute solution if you have a VT100 lying aroun...

Re: Timing Loop Variations

while x x=x-1 loop is the fastest (an IF test and EXIT lengthens the loop. There will also be variations depending on the size of the constant. ARM assembly allows 8 bit values to be loaded in one instruction, some constants can be done by combining shifted constants. For longer one a PC relative l...

Re: Tool for exploring timing of ARMbasic Code Constructs

When I have wanted to measure the time of some function, I usually just to a simple loop i=1000000 while i ' insert code to be tested here i=i-1 loop while loops counting down are the most efficient in BASIC, and therefore the least overhead. On most of the 50 MHz parts this loop takes around 300 ms...
