Errata entry needed for STM32F3
Posted on June 07, 2013 at 00:37 For DMA_CCRx, halfword and byte write access is broken. In both cases, an interrupt is generated on the instruction following the write instruction. Also, if a byte is written to [15:8], the value is replicated t...
STM32F4 Discovery board for ethernet development
Posted on June 06, 2013 at 05:05I went through STM32F4 family and STM32F407VG is the best one which meets product requirement. As you know STM32F4 serial does not integrate ethernet physical layer. So my question is:1. please recommand the ethernet ...
