I am trying to read several adc channels on the stm32 microcontroller, but it won't let me, it only reads the first one.
I am trying to read several adc channels on the stm32 microcontroller, but it won't let me, it only reads the first one. I have seen in the registers that when changing channel what it does is that it sets the selected channel bit to 1 and does not m...
Resolved! STM32G0 - how to achieve 40nA shutdown current as per documentation?
Hi I am using an STM32G071 Nucleo board and would like to know if it is possible to achieve the advertised current of 40nA in shutdown mode.I have no problems entering shutdown mode but the observed current with my nRF PPK2 is closer to 1uA. I have d...
Resolved! STM32G4 Timer Input Filter. Can I read the filtered input pin directly or is it only routed to the timer block?
we use the timer capture for Hall inputs. we were able to program the XOR input using the filter and can geneate an interrupt, but I also want to read the individual inputs using the filter.feature. When I read the corresponding IDR it seems it is ...
DAC Outputs Not Equal
Hello,I use the internal DAC of the processor. Even the initial value of the DACs are equal, I got 1V out from the first output of the DAC, and 2V output from the other DAC output. Why is that happen?/* USER CODE BEGIN PV */ // DAC Settings float...
CANFD multiple senders - Tx Issues
I've been doing the majority of my FDCAN development with 1 or 2 nodes.Recently, I have expanded my "network" to 7 nodes. 4 of these nodes send data at the same time.(I mean, 1 second intervals from power up. They are all powered simultaneously)With ...
Online STM32 selector
Anybody noticed?https://www.st.com/content/st_com/en/stm32-mcu-product-selector.htmlFor what it's worth. After oh so many years.JW@Lina DABASINSKAITE , this is example of information which would need to come from ST here, regularly. This is what wou...
STM32F427 - No SPI4 Communication
Currently, I am seeing no signals on the SCLK and MISO/MOSI lines on the SPI4 lines from a STM32F427 chip to a SPI flash during an attempted read/write. At the moment, I've done the following:Enable GPIO clock (HB1) and SPI clock (PB2)Configure CS:pi...
Resolved! native i3c support
Any chance STM32 MCUs will adopt native i3c support any time soon? Many new devices, including some from ST (like the LPS22HH), support it. It's a compelling (new-ish) standard.
