Differences in setting up for SMBUS:On F4, I set the following bits in CR1: PEC POS ENPEC SMBTYPE SMBUSOn F7, are there similar bits?I see PECEN - is that the same as ENPEC on F4?How do you set up SMBUS on F7? (on F4, it was done with SMBTYPE and SMB...
I've been messing around with a LMT86 temperature sensorThis sensor is deemed high output impedance as the documented loads it drives is 50uA.ADC noise on STM32 isn't 'new'. Just that for a first time I'm observing such volatility up close. The probl...
Hello everyone ; I dont know if this is the right place to write ; we are using stm32f429 in our products we use about 20K / year . we are doing the plan for the next year we are getting a long ..very long shippng dates like 80 weeks ! even now we...
I'm attempting to connect an adafruit SD card reader via SDIO to a Nucleo L476RG.I'm reading through the source code to do a test of the basic read/write functions.Initialization and getting card info is successful. if (HAL_SD_Init(&hsd1)!=HAL_OK){...
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...
