Hi,

I'm writing an DMA library for an STM32F103RBT6. Checking the DMA register addresses I read: on page 193 of the reference manual (revision 9) it is said that the address offset of DMA_CCRx equals 0x008+20d*channel number (1-7). For DMA_CCR1 that's, for example, 0x014. On the other hand, the register map (page 196) states that the address offset of DMA_CCR1 is 0x008.

Maybe that in fact the channel numbering runs from 0 to 6?

best regards,

Jan
