Simple question, I'm trying to locate a user manual for STM32U5xx HAL library but can't find it. The official STM32U5 ST page doesn't provide it. And neither does the STM32CubeU5. Does this mean it doesn't exit yet? But if code is there, then it shou...
Hi ,While checking the "Flash recommended number of wait state for programming delay" list for my project on STM32H723 target, observed the list is not up to 550Mhz. It's showing VOS0(boost mode) [ 70Mzh, 140Mhz, 210Mhz, 275Mhz] , It's listing max LA...
Hello all, I have a fundamental question, I hope it is easy for somebody who has done this before.I started a brand new project for a STM32H7A3VITxQ on Firmware package FW_H7 V1.11.2STM32CubeIDEVersion: 1.16.0Build: 21983_20240628_1741 (UTC)Updated t...
Hi, we are working with a STM32F217 and the RMII bus.In the two documents reported I see an inconsistency on the diagrams (on the one hand rising edge sampling, on the other falling edge). Which one is correct for my chip?RM0033 Figure 328 Reference ...
Dear allI'm starting a design with the STM32L412R8I (or maybe STM32L412RBI6) and I cannot find the VBUS dedicated pin in the datasheet nor in the manual. In this design the USB will be always device (no OTG)Is it enough to have VDDUSB powered to de...
I'm using ADC1 to measure the Temperature Sensor channel and the Vrefint channel. I expect those to vary very slowly and I am in not in a hurry so I am maximizing the sampling time. These are my settings in STM32CubeIDE:It generates the following in ...
This is a question about SPI communication.There is an NSS pin for SPI communication, but is it okay to use GPIO instead of the NSS pin when there is one master and one slave?We don't quite understand the role of NSS. I think it will be useful when t...
Hi,I am using an STM32U545 on which I expect to use ADC4_IN1 and ADC4_IN18 in stop mode 2 (using LPBAM).I want to create two buffer (buff1 and buff2 uint16_t[32]) dedicated to each input.I want to read 32 samples from input1 then 32 samples from inpu...
Hello Dear Community,I am working on an HMI System and using STM32H7B0 with APS6404L-3SQR. I am able to do all operations including Write in Memory Mapped Mode but when I try to write 1 byte, It writes 8 bytes which is not what I expect.I have read m...
Hi Community,During a project we are using the microcontroller STM32H7B0RBT6 with QSPI PSRAM APS6404L-3SQR , it works fine in indirect mode either in quad read and quad write, but the issue is with the write in memory mapped mode when trying to write...
