I'm using STM32F407 as a USB host. I have multiple devices in which we are using CH340E as the USB to serial communication. The problem is if that device somehow turns off and CH340E loses its power. The USB Host can not transmit data to the other de...
I was trying to interface a microSD card (32GB) with STM32F407 through SDIO. Tried 1-bit and 4-bit modes. But it always gets me back FR_NOT_READY. and the program always stuck here: FATFS configuration: SDIO configuration: Clock:Where I'm doing any m...
While uploading/running the firmware/hex to the MCU, the STM32CubeIDE jumps into a random page. How can I stop it? It's really annoying closing those random pages all the time.
I'm using STM32WB55CGU6 (UFQFPN-48) for a design and trying to connect with the ST link. But seems like it is not connecting in any way. Can anyone tell me how can I connect this MCU and upload the firmware to this MCU? Why it is not responding?
I have been using STM32CubeIDE for the last couple of years. Recently after getting a low space warning in C drive found that STM32CubeIDE is taking over 32GB of space in C drive. There I found that some libraries are there with previous versions. A...
What solutions/tips solved your problem? I'm also having a similar problem. No mater what the configuration is, it is not detecting the SD card through SDIO. MCU:STM32F407
Tried with v2 both with clones& original one. It can not detect the MCU. The clonesone uses STM32F103 inside. I don't think it's ST-Link. It's the MCU itself not working. But I tried 10MCUs. also checked the circuit diagram many times. Did not find a...
VDD:3.2V, NRST:3.2V. BOOT0:0.44V if kept open. I used pull-Up/Down options to test. No way it responds. Tried USB, did not work. Did not try USART yet. But seems like all these MCUs are just sleeping. No response. No sign of life.
