Hi.I use a trigger source to trigger SPI tx/rx linked-list DMA (not circular). But have no clues how to jude if the tx/rx DMA is done. I traced the IRQ handler, it calls, the code below: /** * @brief DMA SPI transmit receive process complete c...
Any suggestions as to why power down, then reconnect debugger (JLINK pro) is clearing the TAMP registers to 0?Device is STM32L4P5The clock source seems to be present, it doesn't enter the if statement if (LL_RCC_GetRTCClockSource() != LL_RCC_RTC...
I'm working with the STM32U575 and using all four i2c blocks. My i2c code is interrupt driven.I can't find the right way to check which i2c block trigered the interrupt, suggestions please? void HAL_I2C_AddrCallback(I2C_HandleTypeDef *hi2c, uint8_t d...
I followed this tutorial and I'm able to transmit UDP packets from my nucleo board to my computer. I've configured the code to use lwIP without freeRTOS. I'm trying to receive packets on my board over Ethernet by setting up a callback and it never en...
Dear all,I'm struggeling to get FDCAN2 working on my board. I also use FDCAN1 - which is working pretty good.For FDCAN1 I selected the RxFifo0 and for FDCAN2 I selected RxFifo1.But for some reasons, I dont get the callback for HAL_FDCAN_RxFifo1Callba...
I decided to replace the STM32F105 with the STM32G0B in my project.I have problems setting up FDcan.The STM32F105 had an “automatic bus-off management” setting, but the STM32G0B does not! This feature is enabled by default, how can I disable it? So t...
Hello, I have never used STM before and I am trying to choose a product, but I cannot buy and try each of them due to their prices. I am doing high-frequency work and I need a screen. STM32H735G-DK is a suitable board for me. However, there is a que...
Why the uart stops working on stm32h755 device once the core clock has been modified and code has been generated using cubemx. It comes with a BSP code for serial communication (which i tried seperately) , that is also not working once the core clock...
Hello all, I have to develop an application with a 7 inch screen driver SSD1963,for the choice of cpu. I'm deciding between an STM32H7B3 and STM32F7xx, on the card I need RAM for screen storage,touchscreen management, communication with an FPGA in SP...
Hello, everyone. I'm trying to use an STM32F103C6 to toggle some pins once per second. To this end, I have set up the RTC "seconds" event to fire on the appropriate interval.When busy waiting until the `SECF` bit of `RTC_CRL` is set, it works just fi...
