I'm using an STM32G4 series microcontroller with a Type 3 DMA. It's going to be set up as a SPI slave. It will produce data of x bytes at a rate of 10 kHz and a SPI master will want to read this data at 1 kHz asynchronously. The SPI master will only ...
Hello,I'm trying to use the LTDC peripheral with DMA2D to be able to send a image to the display without using the CPUSo first i used the example LTDC_Horizontal_Mirroring to have a working LCD . Compiling it i have the dolphin on my screen and flip ...
Hello, I'm trying to use the HPDMA1 with channel 0 to transfer the data from UART1 to AXIRAM5 (from 0x342E0000). I want to receive all the data (about 150KB) from the UART through DMA at once (it can only transfer 64KB at once because of the limited ...
I am using the STMG0B1RET on a custom, battery-powered board. During normal operation pin PC4 is used as UART1 (with an external pull-up resistor). In Standby Mode pin PC4 must be LOW in order to shut down the external device. For this I convert PC4 ...
Hello, I have a display connected by PWM to the MCU. I am trying to control it using __HAL_TIM_SET_COMPARE, however I am getting no results. I have a LTDC display.
Hi,I’m working with an STM32H743 and trying to use the RTC. Everything works fine using the LSI, but when I try to use the LSE (with an external oscillator permanently connected to VBAT to keep track of time even when the system is powered off), I ca...
I am experiencing an issue with SPI communication on the STM32F746BG microcontroller:Current Setup:SPI2 connected to ADCSPI6 connected to EthernetCurrent Behavior:When testing SPI2 (ADC) alone: Works properlyWhen testing SPI6 (Ethernet) alone: Works ...
Both STM32H730 datasheet and application note AN5050 mentions that a write operation can be performed on external Flash memories through the OctoSPI peripheral.However, the STM32H730 reference manual (RM0468), has the following info on section "25.4....
I am using a NUCLEO-F767ZI Board.Previously I have not used or configured any GPIO. Then I used CubeMX to reconfigure 3 Pins to Inputs with Pull-Down like this: if (HAL_GPIO_ReadPin(button_uncouple_GPIO_Port, button_uncouple_Pin) == GPIO_PIN_SET) {I...
HelloI have found a bug that stops updating the RTC_TR register. There is no problem with the RTC clock itself, it is ticking but the content of RTC_TR might in some specific use cases stop updating.I use the latest STM32CubeH5 Firmware Package v1.5....
