Hello,I'm working on a projet where I need to drive 4 (or 2 x 4) GPIO at the same time with high speed on the STM32U545RE.I'm trying to use the DualQuad SPI (with OSPI) but I can't have the clock working...At first I tried to write a code with a send...
Hi Everyone,I am working on a project with TouchGFX. I'm working with STM32U5G9ZJT6 and I have an external RAM APS12808L-OBM-BA connected via HSPI (Fclk-hspi 100 MHz) in mapped mode. The project is working, but the image animation are not working wel...
If the STM32H743IIK6 is clocked by an external 25MHz clock generator, but we still aim for minimum current consumption until a wake-up is required, what is the lowest achievable current draw assuming everything is powered down except for the external...
In the last weeks, I was working on running W25Q256 nor flash chip from vendor Winbond with STM32F746 MCU on a custom board. My guideline in this road is ST's how to run QSPI flash video tutorial (5-part video) and of course some genius guys in the c...
:warning:Note: The internal GPIO structure has been simplified for better conceptual understanding. (Components such as ESD protection diodes, pull-up and pull-down resistors, etc., are not shown.):warning:Warning / Disclaimer This analysis is based ...
Hello,I am working on a project where I need to both read and write regularly into the STM32 flash memory. I have some concerns and questions regarding its endurance.First off, I posted a question not long ago about writing to FLASH using ST EEPROM l...
Hi, I am using two rotary encoders on an STM32U5G9ZJT. Currently I have:- TIM8_CH1 and CH2 available- TIM3_CH3 and CH4 available I know that standard encoder mode uses CH1 and CH2. CubeMX shows options like:- Encoder Mode (with remap CH1/CH2)- Encode...
COO DetailsTop MarkingWe are experiencing critical issues with the COO data provided for STM32H5 series MCUs. There is a persistent mismatch between the website (non-China), the physical chip markings (CHN), and the final invoices.If this is not coun...
Hi!I'm building a device using a STM32U31xx, connected to a Network Chip via I²C (PB6/7) and 2 GPIOs for Reset and BOOT0 Pin. The intention is to have new firmware downloaded onto the network chip, and flash new firmware to the STM32U031 via the syst...
Hello Team,We are using the internal SMPS configuration for the core power supply. However, the power-up sequence does not specify the timing requirements for the different stages.Could you please provide the timing details for the following? What sh...
