Posted on January 30, 2016 at 17:47Hey folks, I've been working on USB host driver for MIDI, and so far I can enumerate the device and get data flowing. But as soon as the device is attached I get crazy numbers of interrupts related to IN transactio...
Hello STM32 Teams, I want to use STM32H7A3QIY6QTR + 1.8V HyperRAM solution. STM32H7A3 datasheet said that 1.8V HyperRAM is supported. But I can not find any 1.8V HyperRAM solution from both stm32 community and EVAL Board. All STM32H7A3 VDD Power p...
Hi everyone,I am working on a power-saving application using the STM32G030 series IC, and I need to configure the UART to work at a baud rate of 9600 with an external low-frequency oscillator (32.768 kHz).My goal is to ensure that the UART baud rate ...
I am looking at strategies for updating flash over CAN for the F446 (STM32F446RET6). A small loader program resides in addresses 0-0x8000, and loads the addresses above 0x8000 while there is other CAN traffic running. (This has been done and works wi...
Hello.Has anyone successfully read data from an SD card using CMD18 ( READ_MULTIPLE_BLOCK ) SDMMC in STM32U5?... or ... Can anyone confirm that these microcontrollers have a manufacturing error in SDMMC operation?IDMA from SDMMC reads data into the ...
Hi,We have some problems with booting a mcu (stm32g070), we have custom hardware.i can generate a mxcube project that works fine, every time a power the mcu on the custom hardware. this works onall pieces which we have producedWe created a project (t...
I know in some peripherals, like in a lot of times, the external clock is resynchronized to the CPU clock.In an ADC, that could add jitter. Does anyone know if using an external sample clock on a SAR ADC will be resynchronized to the CPU clock or wil...
In the datasheet of the stm32l053x in the section of "Memory mapping" it says "Refer to the product line reference manual for details on the memory mapping as well as the boundary addresses for all peripherals."I looked at the reference manual and di...
Well, I'm developing a system for reading sensors and sending them to a server.I'm using a GSM LTE module to do this sending. At first it worked well, but after a while the system stopped sending messages to the server.We can see this clearly in the ...
I've successfully set up an evaluation project on the STM32U5A9J-DK PCB with a custom 640x480 MIPI/DSI display in video mode. I've also configured the HexaSPI PSRAM in memory-mapped mode at 160MHz, which I've verified with a scope. My memory tests ha...
