I am unable to control GPIO output pins with the H5 GPDMA. I am able to control GPIO with the F103 using this project...https://github.com/mnemocron/STM32_PatternDriver...where the DMA is much simpler. Section 3.7 of AN5593 (How to use the GPDMA fo...
So new problem while trying to bypass non functioning SWD...Using a working NUCLEO_H723 I can use the STM32CubeProgrammer to access it via STLINK (internal and external) as well as via USB DFU after reset with BOOT0 high.From my reading of AN2606, on...
Here is the code: void DMA_Init_SPI2(void *rxBuffer, void *txBuffer, uint16_t rxSIZE, uint16_t txSIZE) { RCC->AHB1ENR |= RCC_AHB1ENR_DMA1EN | RCC_AHB1ENR_DMAMUX1EN; // DMA1 Channel 1 для SPI2_RX (Peripheral-to-Memory) DMA1_Channel...
I have an STM32G431 doing FOC on a little gimbal motor, but am getting strange noise on the current sense ADC when it's being triggered by TIM3. It shows up as random spikes, which values always end up being dividable by 8. Weird thing is, if I have ...
Hi all, I have an STM32L071VBT6 and want to test the UART functionality. I configured UART4 RX and TX and physically connected them to do a loopback test. I define 2 arrays to start with /* USER CODE BEGIN PV */ uint8_t Send_buffer[] = "Gateway tes...
Hi everyone, I’m working on CAN communication using STM32F746 in STM32CubeIDE.My goal is to transmit CAN frames continuously and verify them using BusMaster or PEAK CAN analyzer,but I’m not seeing any CAN frames on the bus. To help review my setup, I...
As reported here, this is obviously incorrect.Also, this has been already reported by Uwe Bonnes for 'F411/RM0383, which has indeed been corrected in the registers description, but the GPIO register map still contains the incorrect value. So, could S...
Hello,I am not sure if this is the right place to report a documentation errors!There is a typo in Table 11 in page 99. The address should be 0x0803 F000
Hi everyone. I am driving a Neopixel LED with a PWM signal in DMA mode using a timer. Even though all variables are the same, my code works with timer 3, but the same code doesn't work with timer 2 with the same timer configuration. Why could this be...
