ADC Sampling rate understanding

I do not understand the difference between the different sampling rates (cycles3 - cycle480). I know it is related to the time given for the ADC capacitor. I also realise that more time should mean more stable reading. I ran some quick tests and I f...

Output of STM32F100RB DiscoveryVL board when connected to 3v3 converter only shows from 2.58 to 3.19 volts on the input and alway 5v on the output of converter.

I have a Value Line Discovery board - STM32F100RB and three of the outputs are connected to a 3v3 converter to get a 5v output. I have tried another controller board with 3v3 outputs to drive the convertor board and I get a clean signal. (Either 0 or...

Can't erase flash on STM32407VG Discovery

I'm a bit lost by this one. I can write to the flash but cannot erase a sector. I can erase sectors with the ST-Link Utility. The result codes at every step indicate success, but the flash is not actually erased. I am using the Standard Peripheral Li...

Resolved! Sending data to SPI via DMA

I'm using STM32F429 and trying to use HAL library to communicate to SPI slave via DMA channel. I'd like to ask how is resolved problem with for example sending data to SPI via DMA? Is there any kind of synchronization between SPI and DMA to disallow...
