RTC aware file copy

This program copies a file to a new file and runs RTCREAD to update the system time from RTC hardware so that the target file has a correct date and time, if the RTC has correct date and time. Does not create long file names.

usage:
copy d:fromfile.ext d:tofile.ext

Set VS1010D RTC time from file system

Dear all, Here's a VS1010D utility program to set the current time of the RTC to whatever is the latest file creation or modification time in a given directory, if it's later than the current time of the RTC. Usage: SetTimeFrom [?][!][folderspec] Folderspec can be a drive such as S: or D: or a subdi...

Re: VS1000 vs. VS1010

Hi again! Right.. SPI flash and SPI NAND flash are two totally different things and indeed there are 128 megabyte (1 gigabit) SPI nand flash chips in the market, and even larger ones. Ok, so here's the deal. In the ROM, there's no support for SPI NAND flash, but support can be added with a custom VS...

Re: VS1000 vs. VS1010

Hi! Hmm... VS1000 is an old IC, VS1010 is new. Cost is similar. VS1000 is a monolithic target, e.g. it runs one statically linked image. VS1010 has an operating system (VSOS) with built-in filesystem drivers and executes programs from a FAT filesystem (SPI flash or SD card). Both allow SPI flashes w...

Re: ADC solutions for real time parameter control?

Yes, there is SAR AD converter (Successive AppRoximation), a few ch, 10 bits (or 12?)

Re: ADC solutions for real time parameter control?

Inside our office? We would probably use VS1005 instead of VS1053... :D

Re: Standard C libraries not found

Hi! VSDSP supports the original Ansi standard C. Not C99, C11 or other extensions, just plain and simple original standard Ansi C as it's defined in the Ansi C edition of Kernighan & Ritchie's book "C Programming Language" in 1990. All standard libraries are included as they were defined in ISO/IEC ...

Re: Does VS1053 Support i2s In and Out?

Is there any plan to make your devices conform to I2S normal frame length, for compatability with most i2s dacs? Or, a simple way to adapt your existing devices to the standard? Hmm.. :D Funny you should put it that way... You see, when the VS1053 was designed, 32 bits was a perfectly valid frame l...

Re: Are VS10XX Plugins Standalone?

Hi, John, and welcome to the forum! I'm confused. Not trying to combine applications with plugins. I'm not talking about applications. Why do you mention applications? I think it's because you mentioned loading without a uC. And applications are loaded without uC. Plugins are basically always loaded...

Re: Does VS1053 Support i2s In and Out?

VS1053 I2S does not use the normal frame length and most i2s dacs can't handle it. VS1053 I2S uses 16 bits/sample, 32 bits/frame. Most i2s dacs expect 24/32 bits per sample and 64 bits/frame.
