Hi everybody! I keep trying to out a PWM signal, using TIM1 ch1. CC do trigger fine, but the output pin doesn't change. Please help!void TIMER_init(void){ //PA8 - CH1 GPIOA->MODER &= ~((3 << GPIO_MODER_MODE8_Pos) + (3 << GPIO_MODER_MODE9_Pos)); //Sw...
I'm having trouble with my STM32h757 processor. I'm trying to sample 2000 samples using ADC3+DMA1/DMA2/BDMA, but it's not working as expected. I set up the ADC to work in continuous mode and the DMA to work in circular mode with the address increment...
Hi guys,I'm "trying" to establish a STABLE communication between USB FX2LP sync slaveFIFO and STM32 MCU, in particular with the STM32L412KB for now.I need a stable data transfer from STM32 DMA-GPIO to FX2LP slaveFIFO with DMA clock 3MHz (later higher...
I am usinghttps://os.mbed.com/platforms/ST-Nucleo-L496ZG-P/#board-pinoutwith this manualhttps://www.st.com/resource/en/user_manual/um2179-stm32-nucleo144-boards-mb1312-stmicroelectronics.pdfNow I would like to learn Analog-to-Digital Conversion (ADC)...
Hello,I am trying to access an external flash memory (32 mbit) using stm32L4. Stm32L4 has OctoSpi. i have configured the OctoSpi with dual quad disabled but yet, i am not able to access the external flash mem. The external flash memory supports sin...
According to the STM32L433xx/443xx device errata, the result of an ADC conversion done more than 1 ms later than ADC calibration or previous ADC conversion might be incorrect.The workaround suggested by the errata sheet is, "Perform two consecutive A...
Hello,i am using stm32f103C6 ( 48 pin device) and i use TIM1 Channel 3N to generate a pwm via PB15 pin. The tricky part is that i am using SPI12 in receive only master mode.Therefore MOSI pin is not used, but since i have little pins available, i...
Hello, I have two different projects in parallel right now, both of which use STM32G0B1 MCUs. On both projects, with completely seperate hardware, the VREFpin that connects to the internal VREFBUF peripheral is innacurate. These pins are just brought...
Hey all, I'm trying to generate DMA PWM for a row of 3 Neopixels. I succeeded on a Nucleo-based L496, but translating to a L4P5 target (custom board) results in no output on the GPIO at all. I've compared the generated HAL code for both and cannot fi...
Started a project based on the STM32L010 which needs to receive six bytes from the UART. Works fine if I use it in interrupt mode. Does NOT work if I use it in DMA mode. Saw multiple posts about the DMA needing to be init'd before the peripheral in q...
