Hi everybody,I'm trying to set up a communication with a can bus.I'm using a STM32F446. I use PB12 & PB13 (CAN2). I can see RX frames on PB12.I'd like to read frames that I received by using interrupts.I've found this example : https://github.com/STM...
Hi,couldn't find any STM32 dev kit that has DSI display interface and a demo where it plays video (or at least graphics) directly from SD card using DMA.Which ST dev kit does that? Thank you
Specifically, I require a timer for creating a clock to a peripheral. I chose PH5 (Timer12 Channel 2) because of the allocation capability in CubeMX, however, the datasheet for the STM32H757 does not show that as an alternate function.I have confirm...
Hello,I'm planning to use the STM32F413VGT3 in my project. It says it has three CAN buses. Can I use these three lines independently? Some of my research (ChatGPT) indicates that the third CAN line is not a standard CAN bus. I'd appreciate any clarif...
Hi everyone, I'm stuck on the transition from my low-power mode versus my power consumption.I already have a “sleep.c” code that is capable of putting the device to sleep at 2uA power consumption (which is my goal, everything's fine here).This code e...
Hello, I'm using STM32L471 and Micron MT25QL NOR Flash with single SPI interface. MT25 is also connected with other MCU (NRF52) using the same lines. I'm trying to write STM firmware in BOOT0 serial bootloader controlled by NRF using STM's USART3. Th...
Hi everyone, I'm using STM32G474 with dual-bank Flash enabled (nDBANK = 0) and booting from Bank2 (BFB2 = 1). I'm implementing OTA firmware update by writing to the inactive bank while executing from the active one. The update from Bank1 → Bank2 work...
Hi, what is the best way to wake from Low Power Sleep when an Encoder is rotated?I have TIM2 setup in encoder mode and it works when in Low Power Run. I just want to switch back from LP Sleep to LP Run when it's turned. Looking in stm32l4xx_hal_tim.c...
Hello,I'm having an issue with the STM32L4A6(1Mb) and the dual-bank.First of all, I tried with the NUCLEO-L476 and a simple blink led. It worked fine.Now, my project is based on a STM32L4A6, but the firmware doesn't start in BANK2.For simplicity, I d...
I am using an STM32H747i-Disco board for a time critical application. I would like to periodically output simple text messages to the display.but I don't want to use an RTOS, so TouchGFX is not an option. In LCD.c there appear to be no functions to s...
