I'm using a stm32G0 with a UCPD and i'm trying to figure out if the Dead battery pin have any other benefit then just saving the need for 2 resisters on the board. From my understanding i could create the same functionality of the dead battery pin by...
Hi,we are planning to use STM32H742xI/G controller in our design, we have reviewed the datasheet and need a clarification on the IO logic for QSPI.Does this controller supports 1.2v IO logic for the QSPI.
The Errata sheet for STM32G030x6/x8, ES0486 - Rev 6, states in chapter 2.2.9:After connecting the debug interface and until the device power-down, the boot source upon reset or wakeup from a low-power mode is determined by the PA14-BOOT0 pin level be...
So i was looking at the 16-bit ADC characterisics in the datasheet of STM32H723ZG. Here it says for LQFP packages, values might differ. I have LQFP 144 , and i can't find any package specific datasheets. Where can i find the information for my packa...
Moved from this post . Hi @mƎALLEm ,Is VREFINT and VREFBUF output same?In documents I have seen VREFBUF can be set as 2.048, 2.5, 2.9, is that same VREFINT?
We are developing a STiROT/OEMuROT bootloader for a customer using the above chip. This is based on the STM32H7S78-DK sample. The customer has developed the main application and have added support to download a new firmware image over Ethernet. This ...
Hi,I’m using the STM32G491RET6 MCU and currently working on the ADC.I have three analog inputs:Two connected to ADC1One connected to ADC2At the moment, the ADCs are configured to use an external VREF+.I would like to switch to the internal reference ...
I am using STM32F767 with LWIP and LAN8742 PHY.Ethernet initializes but I am facing Ping does not work reliably. This is the Schematic.
I'm trying to read ADC1 on channel 12 using ADC with DMA in a Zephyr OS environment, but I'm getting a BUS FAULT error when using the adc_read_async() API.This is my prj.conf fileCONFIG_LOG=y CONFIG_MAIN_STACK_SIZE=4096 CONFIG_ADC=y CONFIG_ADC_ASY...
I am using STM32U575 (MCLK = 160 MHz) with ADC1 in scan mode (4 channels).ADC conversions are triggered by TIM3 TRGO and results are transferred by DMA in circular mode.Continuous conversion is disabled.TIM3 is configured to trigger ADC every 100 us ...
