MityDSP Hardware Release Notes



Sep 21, 2011
MDK Version 2.10.0 ADS8343 & ADS8344 Version 1.10
  1. Updated a cross-clock domain metastability issue on the latest_sample register to the DSP. This should avoid any issue with the emif sitting on that register. Bugzilla #2019
I2C2 Core (I2C version 2.0) Added
  1. The I2C core was rewritten to support devices requiring 16 bit subaddressing (for example, larger PROMS such as the FM24CL64B). Because of the scope of the rewrite, the original i2c core (version 1.X) was preserved for legacy programs and to avoid regressions. Version 2 and above will be captured in the I2C2 netlists.
  2. Support for 10 bit slave addressing is included, but untested (no hardware platforms available at the time of this delivery).
  3. The number of bytes that may be transferred in one continuous cycle is now 65535. However, you may essentially extend that infinitely by controlling the issue of the stop control bit of the bus protocol. There will be a small delay between commands, however.
  4. Clock stretching/extension is not yet supported.
  5. Slave mode is not supported.
