Hi,I'm trying to implement an external loader for the Arduino Giga R1 board with AT25S128A 128Mbit of external flash. After following the guide given in the external loader repo, I'm running into the problem, that I can erase, write & read from the m...
Resolved! USBX MSC + FileX + NAND Flash - Windows I/O
Hello,I am building and application with a STM32U575 and a 4Gb NAND Flash. What I am trying to achieve now is to upload files from my PC through USB and then used these file within the STM32 using FileX.I already managed to set up FileX and LevelX to...
Resolved! Overcurrent Fault Issue with STM32G0 + TCPP02-M18 PD Implementation
Our team is using the STM32G0 with the USBPD stack and the TCPP02-M18 as the protection circuit. Please find the attached schematic for reference.We are configuring the PD contract with a maximum of 15V, 3A. When connecting an HP G11 laptop to the US...
STM32H7S7L8 dual USB
Hi ,I'm working on the STM32H7S7L8-DK and i would like to know if it is possible to use both USB_FS and USB_HS as two separate Virtual-port-com Device mode When I try to do it for one it is impossible in cube MX to do it for the other.Thanks !
Resolved! Using I3C2 port to communicate with I2C EEPROM (M24C32-RMN6TP) on STM32H533RETx
Hi everyone,I have a question regarding the compatibility between I3C and I2C devices on the STM32H533RETx.I’m using the I3C2 interface on my MCU:PC6: I3C2_SCLPC7: I3C2_SDAOn this bus, I have only one device connected – an I2C EEPROM (M24C32-RMN6TP)....
