This is on the STM32L053R8T6 Nucleo Board. Is there an error on COMP1&2 working in Window Mode?
This issue had been brought up almost a year back, and there looks like there has not been a fix to the libraries?So basically, after code generation with STM32CubeMX, under MX_COMP1_Init, hcomp1.Init.WindowMode = COMP_WINDOWMODE_COMP1_INPUT_PLUS_COM...
STM32F7 SMBUS vs STM32F4 SMBUS
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...
Resolved! ADC noise on stm32f401
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...
stm32f429 shortage
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...
Trouble with SDCARD - SDMMC_FLAG_RXOVERR
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){...
STM32L071x8 GPIO configuration as analog input or input
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...
Resolved! STM32H7 crashes when reading the last bytes from a memory-mapped QSPI
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...
Resolved! There seem to be a mismatch in the STM32H747 documentation: The 176 pin version should have an VDDDSI pin, but it's missing in the pin definition and in the pinout. Is it a typo?
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 ...
AT commands via UART, STM32F4 -- ESP8266
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....
