What's the difference between STM32L4S5ZI and STM32L496RET?
Hello, I just wanted to ask is there a big difference between STM32L496RE and STM32L4S5ZI. Other than STM32L4S5ZI having a larger RAM and memory. As well as no display interface but with encryption. I'm asking because the STM32L496RE is now out of st...
How to Turn ON the STM32 with button?
Hello!I have a question about power supply and ON/OFF capabilities of microcontroller.Normally, When power supply is turned ON, the microcontroller Start executing the program.In my case I want that after Power supply is turn ON, the microcontroller ...
Resolved! How to make use of "Normal Mode" available in bxCAN(STM32L476RG Nucleo Board)?
I can able to do "Loopback Mode" and I'm getting the desired output signal(CAN_TX). When I opted "Normal Mode" I can not see any output signal at TX pin.Here I have selected polling method only and not used any of the interrupt(eg:CAN1_RX0,TX Interru...
STM32F2xx USART DMA read gets stuck (timeout), unable to recover?
First time posting here, please bear with me if I'm making some rookie mistakes.I am having a weird issue with the USART and DMA reception of STM32F217VG. There are two issues that I am struggling with:1) not able to find the reason why the DMA read ...
Resolved! How can I use Capture Compare as external trigger source?
Hi!This might be a simple question, but I still haven't solved it. I want to create an external trigger source for SDADC 16-bit and I have selected TIM12 Capture Compare 1 as external trigger source. Then I have enable the Output Compare, because I d...
Unable to read from ADS8686S properly via SPI
I am trying to read registers from an ADS8686S ADC from TI. It has the following timing diagram for register reads (from https://www.ti.com/lit/ds/symlink/ads8686s.pdf?ts=1624204868114&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FADS8686S):...
Error in the NUCLEO www page https://www.st.com/en/evaluation-tools/stm32-nucleo-boards.html
In the Nucleo page https://www.st.com/en/evaluation-tools/stm32-nucleo-boards.html the links are shifted: E.g. the link for NUCLEO_G491RE is to NUCLEO_F401RE who is just above.Another remark: some NUCLEO do not have a link to a page.
