I've been trying to find examples of HAL-based i2c messaging, such as writing changing to reading without restart condition, and request-response messaging (= start, arbitrary number of bytes written, restart, arbitrary number of bytes received, stop...
I have MPU6050 accerlometer, i need to interface with stm32f0 (via I2C).Firstly i am check if the sensor is responding by reading the"WHO_AM_I (0x75)" Register.If the sensor responds with 0x68, this means it’s available and good to go.but the code is...
Hi,I would really like to understand why ST changed SPI on H7. What can be done with SPIx->CR2.TSIZE? Is it possible to generate an ISR only after TSIZE bytes transfer?Why 16 bytes FIFO? Is it possible to generate an ISR only after 16 bytes transfe...
Hi,I'm developing a PCB which uses the STM32H750VBT's timers TIM2 - 5 to drive a bunch of LEDs for a user interface. I've verified that the timers are all outputting their data correctly. The start of TIM2, 3, and 5 are all triggered by the start of ...
This micro-controller has 16 Analog channels and I have read somewhere that all of these analog channels are sharing the same ADC. I want to connect 8 RTDs to the analog channels and I want this micro-controller to do conversion simultaneously. Is i...
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?
