STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Using an STM32F373, I setup a USB DEVICE virtual port class. The connection does work but it takes disconnecting/reconnecting the USB cable once or twice before it gets detected successfully as a serial port/usb device on my linux box. I use lsusb ...
Hi AllI'm having a problem with FDCAN transmissions and would appreciate any insights. I have a pair of H563ZI Nucleo boards, and am transmitting FDCAN messages, but the 20th of the 29 bits in the FDCAN extended identifier is always received as 1, r...
I want to port a STM32F103C8T to a STM32F1 series. I go on my .ioc file, click the pinout compatibility and then find the board but i can't seem to see the import option anywhere. Image is attached
Hello, SDIO 4 bit R/W with 32 bit HC works. When 64 GB XC is used getting error at:SD_PowerON() > HAL_SD_ERROR_CMD_RSP_TIMEOUTMore questions: when to enable HardwareFlowControl (at times R/W is success when enabled) and why set BusWide as 1 initiall...
