Hello,what is the difference between configuring GPIO pins from software and leave as default(no code). does it have an impact on other register settings that are not being set/clear in default configuration. because I am having a problem when I leav...
I'm trying to use memory-mapped QSPI with STM32H743XI, but it always crashes when reading the last few bytes (something like 96 bytes before the end address, but not entirely consistent). It crashes without a fault and just disconnects the debugger a...
According to the STM32H747xI/G datasheet, the STM32H747IG has a VCAPDSI pin, but no VDDDSI pin at all.I'm sure i get something wrong here, because without VDDDSI pin, the VCAPDSI pin would be a miraculous source of energy! ;)But seriously: do i have ...
Hello everbody!Im new to the STM32 platfor, and i want to learn about it. For a personal project i want to make de device that tracks a crypto valuta. Just for fun.I have a ESP8266 with the AT firmware, and I could send commands via FTDI using putty....
On this site:https://www.st.com/content/st_com/en/arm-32-bit-microcontrollers/arm-cortex-m0-plus.htmlit says that STM32G0 have bit banding, other sites state that Cortex M0 and M0+ don't have bit banding, also I can't find a define of SRAM_BB_BASE an...
Dear all,I was trying to verify STM32F479 and STM32L476 microcontrollers compliance with SD memory card version 3.0. Both reference manuals state "Full compliance with SD Memory Card Specifications Version 2.0".Using HAL functions provided by ST I ha...
I am trying to set up a hal can receive interrupt. After thorough googling, I found that HAL_CAN_Receive_IT is deprecated and that I should now be using HAL_CAN_ActivateNotification with a callback function. Unfortunately no one describes how to do t...
Hi all,In the past, I've used HAL_UART_Transmit() with HAL_UART_Receive_IT() which freeze RX interrupt in case of RX interrupt while TX is still processing (see https://community.st.com/s/question/0D50X0000AhPrkRSQS/haluarttransmit-with-haluartreceiv...
Seen this on two board designs, about two year different in age and many steppings of STM32H7The H743I-EVAL and H745I-DISCO have 1Gb (128MB) of Micron QSPI flash, one as a dual die single chip, the other as two SOP16Using the BSP code I can access th...
In AN4899 it specifies that one should add a zener diode from the 5V rail to the 3.3V rail in order to have complete safety when using FT pins with 5V pull ups. Does anyone know what the specifications of the Zener diode should be (currents, resistan...
