Hi. I have a simple custom board with STM32F412CEU6. I can't connect to the MCU using the ST-LINK through SWD. Here is the circuit. I have tried different settings, still getting the error. I verified all the voltages and settings. They all seem ok. ...
Hello,I'm trying to do pattern generation on GPIO port using DMA timed by TIM trigger, but I cannot make it running.My code:TIM2 INIT void MX_TIM2_Init(void) { __HAL_RCC_TIM2_CLK_ENABLE(); HAL_NVIC_SetPriority(TIM2_IRQn, 3, 0); HAL_NVIC...
Hi Community,I’m having an issue with connecting the STMStudio application.When I plug the programmer USB into the computer, the connection works without any problems. However, if I upload code via Keil uVision, I am unable to reconnect to the STMStu...
Following on from this question USB FS speed vs USB HS with internal FS Phy with DMA it seems that USB HS has access to DMA but there is no information on how this is configured. I do not see any additional DMA options appear in Cube IDE when I have...
I have spent a few days trying to select the correct MCU for a project and trying to minimise the need for external ICs For example, I need the STM32F479VI MCU to appear as a USB Full Speed (480 Mbps) device.However, in CubeIDE, when I select USB-OTG...
Hello, I am a little advanced STM32 user, but I quite struggle with eMMC memory and STM32F7 (on custom board with STM32F756I and Samsung's 32GB eMMC KLMB2G2JENB-041 in the 8-bit MMC interface). Optionally I can solder STM32H753I which is pin-to-pin c...
PLEASE GUIDE US FOR SELECTION OF 8MHZ CRYSTAL FOR STM32L462CEU6 MCU.
Hi, I wish to calc a CRC using the CRC peripheral for some byte data and am using TouchGFX which as I understand it also uses the CRC peripheral. I tried using the CRC unit but I am not calculating the correct ethernet 32 bit CRC for my data. I susp...
Hello, ThereI am trying to implement NEC protocol to implement the IR remote driver, but my code is triggering the p infinte-loop. As I tried to find the problem. I think the problem caused by the following lines: time = ((float)tim_Counter * time_i...
Hi @Amel NASRI, Thanks for sharing the info here. I'm really interested in low power MCUs. I do have one question: where can I find information about the startup current draw of this part? The datasheet has very good documentation on the supply c...
