Hi,I have a problem with the ADC2 calibration on STM32H743VIT6(V). I use ADC1 and ADC2 in dual mode(Regular simultaneous mode). On some boards the ADC2 calibartion doesn't work. (The ADCAL-Bit in ADC_CR is not cleard after start).On the boards where ...
I am using an STM32f446RCT6 microcontroller in my hardware, and I need to use a virtual COM port on this device. I have enabled the USB device in the middleware as a virtual COM port, and my system clock frequency is 16MHz. I am using CDC transmit to...
I am developing my own hardware debugger (SWD based, as a hobby project) for an STM32F0 based board. I have access to the official ARM documentation about the hardware implementation of the SWD debug functionality. This however only mentions the vari...
Hello every one I want to use EMMC instead of SD card with SDIO interface with STM32F407VET6. I have tried SD 1bit and 4bits wide bus. (I am choosing SD to enable FATFS)First I've used f_mkfs to create a File System on the eMMC. It returns FR_OK. And...
I am using RTOS based timers in STM32F205VET6, does it have any constraints or restrictions on using RTOS in my project like how will it affect my program ,Any other limitations are given like only this much tasks/timers only we could use...?
Hello,I want to use ST's default OpenBootloader that the virgin chips have on board.The pheripheric I wanted to use is the UART1, and on the AN2606 Application note I saw that the pins I need to use are PA9/PA10, or to be more precise PA11/PA12 sinc...
I'm trying to set TIM2 in PWM mode, but I'm getting weird results. CH1 to CH4 are enabled but CH3 on PA2 shows no output no matter I do. The weird thing happens when I try to remap TIM2. There are three remap options, Remap2 is the one I'm intereste...
Why does PB9 idle high in reset for the STM32L4P5? At least I'd like to know this the next time I design a board, where I could find this reference. Full part is STM32L4P5RET although I'm guessing its the same across multiple parts.
Hello,I have problems with building the cdc_msc example on STM32CubeIDE. My board is STM32F411 blackpill.I have followed the instructions in https://github.com/hathach/tinyusb/discussions/633 but get errors when building.Below I will link my entire p...
Customized hardware with STM32H723 + LAN8740A for MII mode.LWIP Settings:#define NO_SYS 1#define LWIP_DHCP 1 #define LWIP_NETIF_HOSTNAME 1The DHCP client, UDP and TCP server and ICMP(Ping) are all working fine.But host name didn't show up on DHCP ser...
