Posted on December 12, 2012 at 10:22I need to scan 3 ADC channels each second.I prefer to use ADC3 for all of the channels to save power.The example below uses ADC3, channel 7 with DMA2 stream 0.Can I configure the DMA+ADC so I'll will have all thre...
Posted on December 12, 2012 at 22:34I'm trying to program an STM32F415VG on a new board design. The board has power (3.3V) and the connectivity appears to be correct from the 10-pin Cortex Debug header to the chip although I'm doublechecking right n...

Posted on December 10, 2012 at 03:33 I have been trying to get UART working for the last couple of days with no luck. I have tested an UART example code and it worked. So clearly there is something I am missing. I would really appreciate any hin...
Posted on December 10, 2012 at 18:29Hi all,I noticed that there is an high traffic in I2C2_EV_IRQHandler() with status 0x70080 (EV8 =I2C_EVENT_MASTER_BYTE_TRANSMITTING) after all the bytes was transmitted with success by DMA (but it's the same probl...
Posted on December 12, 2012 at 10:29I have face a problematic state.After I finish to collect on DMA and get TCIF0=1 I collect the data and reset that flag. After that I want to write a new value in the NDTR so I disable teh DMA by register S0CR->EN...
Posted on November 13, 2012 at 17:38 I want to create a simple PWM implementation which uses an external clock source and is synchronised to a trigger pulse (one pulse per PWM period). I need at least three (ideally four) channels of output with...
Posted on December 01, 2012 at 22:27I need to configure a software reset so that it occurs when my firmware detects that my ADC value has reached a maximum or a minimum value. I realise that I need to have a RCC interrupt.Is there someone who can he...
