Hai All!I use 2 pieces of APS25608N PSRAM on OSPI bus with memory mapped mode. The MCU run at 1.8V, 160MHz system clock. Previously, I used APS12808N at 80MHz and 3.3V VDD without any issues.Currently, the PSRAMs run at 50MHz, but need to speed up to...
Hey guys, I'm looking for some suitable HexaSPI PSRAM and also the OctoSPI Flash for the STM32N645 board I am just building.. I cant find the parts used on the DK so do you have a list of supported memories? I need 256Mb PSRAM and will start with a 1...
When I write code, should I keep the microcontroller on, or turn it off and only turn it on when I want to test the code?
Hi, I use the stm32f103 to read the IMU(BNO055) via I2C to get the Quaternion data,I use this library from ivyknob, https://github.com/ivyknob/bno055_stm32The AR Anchors result is well (Head Mount Display application), I use the USB VCP to Transmit t...
Hello, I am planning to use the STM32G474RET6 and would like to confirm whether I can use the internal VREFBUF. This product's package is LQFP-64 and while reading the datasheet I noticed the note : ''The VREF+ pin is double-bonded with VDDA on some ...
Hello,I stumbled over a weird problem when trying to debug Memory Protection Unit (MPU) settings which I want to document here in case any other people have the same issue:SetupThe used MCU is a STM32H7S3L8H6 on a STM32H7Rx/7Sx Nucleo-144 board (MB17...
Hello,The datasheet and reference manual are missing information about the 4 KB Backup SRAM in the memory map.Where can I find details about it?We need to use this memory in both Secure and Non-Secure projects.Thank you.
I am implementing a TCP Server on an STM32H563ZI (Nucleo-144) using NetXDuo. The software initialization part is working perfectly; the ThreadX kernel starts, and NetXDuo reports that the IP instance (192.168.2.55) and TCP are successfully enabled.Th...
Hi,The external nor flash AT25XE321D is 32Mbits, support quad IO/XIP spi operation, max. 133MHz Freq. Std. JEDEC/SFDP. It is connected to STM32H7R7Z8J6 with with XSPI1 port-1 interface.I am using MX v6.116.1 to setup project for my board. By IDE v2.0...
Dear all,I'm trying to generate a waveform using DAC OUT1.I configured pin PA4 as analog (works)I configured DAC1 without DMA and it worksI configured TIM6 and it works Then I configured DAC with DMA, configured DMA, but output never changes.Where ca...
