Hello, I use the DAC together with the DMA in circular mode to generate a sinewave of a few Hz. A buffer is filled with the predefined values of one sine period. The frequency is adjusted with the DAC clock and the sine amplitude by updating the sin...
I have application that fits comfortably in 128K bytes and has some persistent storage (data tables that are occasionally written by the application journaling-style, and occasionally a need to erase some of the data to accommodate more Here is my qu...
I have a product line using an STM32F427ZIT6 MCU which has been in production for several years. Suddenly it seems to be unavailable. Both Mouser and Digikey have zero stock and cannot even quote a lead time. Our production will be halted very soon. ...
I am trying to use the RNG on the STM32L4A6ZG but every time I enable the RNG clock RNG_CR |= RNGEN the RNG_SR shows CEIS and CECS.The AHB bus is at 80MHz and RNG_CLK is at 48MHz. I've tested with configuring the RNG_CLK to come from either the HSI48...
Attached images of both systems and I really appreciate suggestions to understand and be able to solve the problem in debian.

Hi,I'm almost new to the STM32 and have the following question: I'm triggering multichannel ADC1 conversions using timer 1 and storing the readings in a buffer using the DMA. It works fine until I configure ADC2 (which doesn't support DMA) to be trig...
