After using cubemx, I tested the single channel round-robin acquisition and there was no problem.After changing to DMA acquisition, as long as VREFINT and VBAT exist at the same time, the data of the first channel is wrong. The following is the corre...
Posted on July 14, 2014 at 12:19 Hello, I have a trouble with my DAC, for example when I set the DAC output (Channel1 orChannel2) to the maximum voltage, the DAC generate the minimum voltage: DAC_SetChannel1Data(DAC_Align_12b_R...
Posted on May 30, 2014 at 17:16Any ideas what would cause a STM32F4 Discovery board to suddenly invert the DAC output, such that 0 gives 3V and 4095 gives 0V? This does not seem to be a programming issue as the identical program worked fine prior (a...
Hi, I'm trying to set the following parameters for I2S in Device Configuration Tool (STM32CubeIDE v1.14.0): - Master Clock Output enable - audio frequency: 48kHz - Data and Frame Format: 16 bits I want to connect an external 12.288 MHz clock to the A...
I am working with an STM32D103C8T6 and I want to store some data on the flash memory.I have some idea on how to do It but not sure about some details.My procedure is the following:1- Add a new section in linker at a defined address near the end.I und...
Hi, I'm trying to use AMC1336 Delta-Sigma Modulator with STM32U5A9 MDF. I have tried using polling and interrupts for data acquisition and got expected results. But when I tried switching to GPDMA the data jumped around and is not usable. I took 100 ...
Here's a corrected version of your text:Hi!I would like to ask the community if my design of the SDIO and USB bus looks fine. Previously, I was using a dev board (BlackPill STM32) to write data to an SD card, but I encountered some issues during the...
I’m new to the STM32L4 community and currently working on an assignment for my studies, using the STM32L475VGT6. My task involves configuring the DFSDM to acquire audio data.I followed the setup tutorial in this video: https://www.youtube.com/watch?v...
Hi ST.Can help to advise on how to interpret on the body marking of the of the IC below? And what is the red marking on the chip itself? Are there any changes on manufacturing process regards to this part? STM32F723ZET7 Thanks.
I want to monitor my 4.2V battery and cant find any MCU which can convert such high voltage . It will be even better if it has differential ADC [can do 1.5-4.5].Previously tries STM32F303C8T6 but all the ADC pins are only 3.3V Tolerant. Its my first ...
