Another year has passed and to celebrate the new year I am releasing some brand new libraries.

The first library is SPIflash. The library supports a variety of SPI flash memory chips from SST/Microchip and Winbond. You will have full access to read and write to the entire chip or use the simple filesystem I have implemented. The filesystem is currently read-only.

The second library is UTFT_SPIflash. This library is an add-on library for UTFT and SPIflash which allows you to load both color and monochrome images from the flash chip and display them on any UTFT-supported display. It also supports displaying sections of color images.

Third and last is the LCD5110_SPIflash library. With this library you can load images from the flash chip and show them on a Nokia5110 display. This library only support monochrome images (naturally) but does support displaying sections of images.

All three libraries are supported on both Arduino and chipKit platforms.

And the first update to SPIflash is out.

An old version of the FlashUploader tool had managed to sneak into the v1.0 archive. FlashUploader has been upgraded to the correct version in v1.01.
Sorry about that...

A new library today: DS3234

The DS3234 is an extremely accurate RTC according to Dallas/Maxim. This has also been my experience :)
So far I have only measured a drift of a few milliseconds over 24 hours. The DS1302 and DS1307 have been measured to have a drift of close to 1 minute over a 24 hour period.

Two new libraries today: DS3231 and MCP4725

DS3231:
The DS3231 is another extremely accurate RTC according to Dallas/Maxim. This is also the RTC used on the ChronoDot.
It is much more accurate than the DS130x RTCs, and it does not require an external crystal/oscillator.

MCP4725:
The MCP4725 is a low-power, high accuracy, single channel, buffered voltage output 12-bit Digital-to-Analog Convertor (DAC) with non-volatile memory (EEPROM). Its on-board precision output amplifier allows it to achieve rail-to-rail analog output.

Both libraries are available for both Arduino and chipKit.

I sorry if the recent server down-time have caused any problems.

The Virtual Host running both my web-, database- and email-servers died due to massive overheating. Several of the capacitors on the motherboard popped...

The servers are now running on my backup Virtual Host and should again be fully functional. There may be some minor down-time in the days to come but each of them should not last long (probably not more than one hour).

Oh, I so need a new server...

Several smaller updates today due to the recent tool-chain updates in Arudino 1.5.7.

The following have been updated:
• Library: LCD5110_Basic
• Library: LCD5110_Graph
• Library: MGLCD
• Library: UTFT (inluding the supplied tools)
• Library: UTFT_Buttons
• On-line Tool: ImageConverter 565
• On-line Tool: ImageConverter Mono
• On-line Tool: Font Maker 5110
• On-line Tool: Font Maker UTFT
• On-line Resource: Icons
• On-line Resource: UTFT Fonts
• On-line How-To: UTFT Fonts 101

Please note that the updates only apply when using Arduino 1.5.7 with AVR microcontrollers.

If you experience problems with previously converted or downloaded icons, images or fonts you should reconvert or redownload them before contacting me.

Please contact me if you still find any compatibility issues as I may have missed some. There were a lot of minor changes needed.

Another update to UTFT today. Current version is v2.79.

Changes:
• added support for more display shields and modules from ElecFreaks
• removed all support for display modules from GE-Tech (including the ILI9320 driver)

----------------------------------------------------
I do not like to remove support for any device from my libraries but it looks like GE-Tech have made some changes to their display modules and I am not sure if their current products would be supported by UTFT. I have tried contacting GE-Tech to clarify the issue but after waiting two weeks for a reply (from their support dept!) I gave up. I cannot in good conscience keep providing support for a company that does not even reply to their support email.

ILI9320 support has also been removed since there are no currently supported displays that use it.

I will not be able to provide support if you are using a GE-Tech display module from today.

SPIflash has been updated to v1.11.

Changes:
• fixed a typo in the FlashUploader chip list
• updated FlashUploader to v1.1
• updated the SPIflash_FlashUploader example sketches
• reduced default SPI speed from 20MHz to 13MHz for chipKit due to some instability issues

Uploading datasets from FlashUploader through a serial link should be a lot more stable now, but it still takes a loooong time for larger datasets.
