I have enabled USB Device FS and successfully use it as a virtual com port.I now need to determine the best way to send messages from master to slave over this port, and how I will handle potentially corrupted data, timeouts, and how enabling CRC wil...
Dear ST,I try to use SPI1 in full-duplex slave mode with hardware NSS and interrupts.Interrupts work fine, the only problem is that data is all 0After connecting the logic analyzer I noticed that the CS and SCK signals are ok but the MOSI and MISO ar...
Hello,I'm trying to use the I2S transceiver on a STM32H7.I did a first simple experiment using the HAL function: HAL_I2S_Receive_DMAI use a basic loop in the main:while (1){ if (i2s_bsy == 0) { i2s_bsy = 1; i2s_status = HAL_I2S_Receive_DMA(&hi...
OK so here is the finale of the trilogy (first two installments here and here).If SDA is pulled low externally *after* I2C is enabled by setting I2C_CR1.PE, I2C_SR.BSY goes high; and if under that condition master communication is started, there's no...
i am using IMU ICM-42688-P sensor communicating with stm32 GOB1CET6N board using spi protocol. but, i am not able to read WHO_AM_I Value for more than 2MHz frequency. i have tried all settings but nothing is working. datasheet of sensor says SPI work...
I'm using a Nucleo-H563ZI in non-secure mode.When I access the FLASHSIZE_BASE address:#define FLASHSIZE_BASE (0x08FFF80CUL) /*!< Flash size data register base address */I get a hard fault (16 or 32 bit access).In the debugger the memory dum...
Hi to all!I have the following question: why do the relays in the circuit start switching when I connect the STM32F1 microcontroller to the computer through the programmer?And similar happens when I initialize RCC. As if all the contacts are being ch...
Greetings,I'm attempting to make use of the tamper backup registers.I am enabling the RTC and have using LSI as the clock source.ROP is not enabled, I am not using the TAMP input pins, and i am debugging via SWD.As it is at the moment, writing a valu...
I am using STM32G0c8t6 microcontroller to make a BLDC motor controller. I am connecting the Rx and Tx of UART to a VCU and they are sharing the same battery. Apart from these, there is no other connection between them. And sometimes, for some unknown...
Hi Team i am facing some issue related to flashing code. previously i flashed the STM32Cube_FW_WL Lora wan example code into my stm32wl5cc controller PCB using J-link debugger. after successfully flashed the code i am trying to flash another code int...
