I am writing data to an SD card for a data logger application, but I have very little experience with writing to SD cards so I want to ensure I am writing the data efficiently.My understanding is that data is written as a sector of 512 bytes. So eve...
Hi,Does anyone know if it's normal for the RTC_IRQHandler not to trigger when the MCU wakes up from standby mode using the wake-up timer? I tried setting a breakpoint in the RTC_IRQHandler, but the problem is that it doesn't hit the breakpoint when t...
Hello,STM32F103RB microcontroller.7-bit master transmitter (see Figure 273).When I send Address then I receive AF bit of I2C_SR1 register equals "1" (Acknowledge failure). But the diagram taken from the oscilloscope shows that after the address there...
Hello :)I have created a project for a STM32H745I_Disco board in TouchGFX, imported it to STM32CubeIDE and enabled:USB_OTG_FS -- Host_Only and VBUS sensingUSB_HOST_M7 -- Mass Storage Host Class + Platform settings for enable PinFATFS_M7 -- USB Disk, ...
HelloAfter running the code for about one to two hours I always get Hard Fault exception. Readout of the registers in this Hard Fault while loop are:HFSR=0x4000 0000CFSR=0x8200BFAR=0x20020000MMFAR=0x20020000AFSR=0 Readout of the SP register shows:SP=...
Hi All,we are evaluating the possibilty to use a BiSS-C encoder in our project. First time using BiSS-C.From the BiSS-C standard it seems to me that BiSS-C can be implemented at STM32 level by mean of an SPI peripheral connected to an Rs422 transceiv...
Found a bit of an odd issue when switching from MSI (with a 160Mhz sysclock) to HSE (also with a 160Mhz sysclock).We're using the HAL_UART and its giving a error callback with a zero value uart->ErrorCode.The cause of it seems to be in the library HA...
I have timer 1 setup to PWM a wave form and timer 2 setup to PWM a different frequency wave form. I need to restart timer 2 when an output compare match (CNT = CCR) on timer 1 occurs. It appears that I can do this with master/slave configuration of...
I want to generate a ~200us pulse on the DAC (variable output) that occurs at 20Hz.The DAC itself is no problem, the 20Hz is done with a timer interrupt.What is the best way to implement the 200us timing? Preferably non-blocking, Another timer that s...
Hi,Is it possible to distinguish an STM32G0B1KBU6N from an STM32G0B1KBU6 based on the UID?Is it possible to read this UID in FW in order to recognize whether the correct controller is fitted or is this only possible via the SW interface?
