The TI motor drivers mct8329a and mct8316 require 100us delay between i2c data bytes. This can't include the acknowledge bit, but requires holding down the clock between transfers for the 100us. it is due to a bug in the TI chips that can't stretch c...
Dear all,I have dev a custom board pcb based on stm32h743ii with 32MB of flash and 32MB sdram FMC for a 7 inch lcd HD. I am new on cubeide i coming from esp32 world and i have some programing dev question .Is it a good idear to implement :To parti...
I am working with the STM32U5G7 microcontroller and have successfully implemented entry into STOP2 low-power mode. My system clock is 80Mhz(HSI, PLL), However, upon wake-up triggered via LPTIM . LPTIM is configured as counts internal clock events wit...

Pin 2 is connected to Boot0. is it Okey to do this (not using resistors).?
Dear STM Community and Experts,we are trying to implement a dual-port USB-C design using STM parts with the following requirements:Port 1: USB-C Power Delivery (PD) Sink, 100W, no dataPort 2: USB-C non-PD Source 5V 2A max., USB 3.1 Gen 1 Data, Displa...
Hi, I have Interface (type MASTER) 10-bit + CLK, FCLK=~9MHzCan I use DCMI to read 10-bit without VSYNC and HSYNC?Or some other method? The usual assembler software method "ldr r1, [port, #....]" is too slow and despite many attempts it has not been p...
Hello, I am implementing audio streaming with H753 board. My goal is like below. 1. Input : USB connected PC, which can be selected one of 48kHz and 44.1kHz sample rate on connecting state. Others are fixed as 16 bit / 2 slot ( stereo ) 2. Ou...
Hello All, I am doing this post after trying everything I can to solve my Issue. I have a STM32F411 Blackpill connected on an Apple II Bus Slot.The Apple II has a clock (Phi0) close to 1 Mhz. Phi0 is connected to Pin A2 where I have setup a Falling &...
Hi all,I'm building a discharger using my STM F446RE, such that it's RTC registers are used to store data that'll be loaded to set parameters in my code every time the discharger is plugged into the power. Just to clarify - I'm NOT using the RTC as a...
