I call HAL_PWR_EnableBkUpAccess() but writes to backup RAM (4K in battery backed domain) won't stick. Data always remains 0. No error or fault on write.What else can be missing??RTC backup registers write test on same board is successful (means, tamp...
Hello,On my custom design board, I use external 12 bit ADC (ADS7886) and STM32F767VI. I try to get digitized ADC values with SPI interface. I set the SPI as Receive only master than prescaler as 8; baudrate as 13.5 Mbits/s; polarity as 1; phase as 1...
Hi everyone, I'm using SMT32L073RZ as my MCU and it has connected through SPI a flash memory (microchip's SST25VF016B).So the connection is as follows:PA5 ------> SPI1_SCKPA6 ------> SPI1_MISOPA4 ------> SPI1_NSSPA7 ------> SPI1_MOSI)PA0 --...
Posted on July 05, 2017 at 10:53While using SDMMC with FatFS to interface with SDCards occasionally I get Command Timeout when issuing:SDMMC_CmdReadSingleBlockThis is when using new 1.7.0 drivers. Did anyone experience similar issue?
There is no TIM5 in the 'F0.Textual search for TIM5 in RM0091 rev.9 reveals it occurs twice:in Internal clock source (CK_INT) subchapter of TIM15/16/17 chapter; this is a typo and it ought to be TIM15 (because TIM16/17 don't have the slave-mode contr...

We have a system up and running with STM32H743 and are very aware that Rev Y is really a buggy one. Rev V is supposed to fix most of the problems (USART handling, reading 2 CAN Busses in parallel, etc.) We contacted several distributors (DigiKey, Far...
MODBUS RTU frame start and end with >=3.5 char interval i want to detect this interval using stm32 uart interrupt after detection of frame and i can process data further.How can i detect this silent char interval using uart interrupt or any other way...
UART DMA receive unknown length of data (maximum data length 64 bytes) but in every message terminate with 3.5 char times silent interval ( MODBUS RTU FRAMING) so to detect silent interval i'm using IDLE interrupt occur before new message start.When ...
Hi,I try to work with the JSN-SR04T distance sensor. The working principle is very simple :put the trigger pin to high for 10 uscount the elapsed time in us on the echo pin between the rising and falling eventdistance is proportional to the elapsed t...
