STM32L031G6U6 - Stop mode I2C back-to-back transactions not working
Hello,I've got a setup where I put the STM32 into STOP mode, with wake-up on ADDR match on I2C.SYSCLK is PLL 32 MHz.APB = 32MHz.I've configured I2C to use HSI, and enabled STOP_WUCK.(The I2C uses DMA).If I enable HSI16KERON then the device responds a...
Resolved! Could an stm32h7 be a graphing calculator
I was wondering if an stm32h7 could run open source calculator Firmware epsilon, i would need to rewrite an interface layer, and don't want to work for days so i can find out that the stm32 is not strong enough.
Two physical USB ports (host and device) on STM32H7 possible? Better ust STM32MP13x?
Hi, i need to build a system that has two physical USB ports:- USB-Host: Type-A USB2.0 HID device to connect an external Midi-controller- USB-Device: Type-C USB2.0 or USB3.x to act as a multi-channel audio sound card, and also HID device (MIDI contro...
