Hello,I'm trying to figure out the max. reliable clock frequency for NOR flash connected via SPI or QSPI interface.I've read here or here that there are custom board and evaluation board designs which are reading data at single transfer rate up to 1...
Hi.I'm not very familiar with STM32 yet.Can STM32F103 delay up to 62ns or 125ns to raise GPIO and lower it again during that time interval?Thank you :)
Hello,I had a problem with Nucleo H723ZG ADC, i needed ADC error to be less than 1mV and a sampling rate of 2.5MSPS, but the built-in ADC was having errors around 20mV. (topic).So i decided to proceed with an External ADC, ADS9219 The problem with th...
Possible errors in PM0223 STM32 Cortex®-M0+ MCUs programming manual (version 9.0, 20 Jun 2024):Detailed description of possible errors are giving fully in 'possible errors.pdf'At last part of the pdf doc, you can find corresponding file version and d...
Hi，There is a STM32F407 on my board to configure and control the optical module. Also, STM32F407 use SPI to interface with CPU. STM32F407 work as SPI slave mode, and CPU work as master mode. Some protocol require one flow control byte in SPI timing, ...
Hello all, I have been struggling with DMA transfers from SPI transactions and would love a second opinion on what I could be doing wrong. I have confirmed that polling works and I can corroborate the data I see in the RX registers with a scope. I do...
HI,I need help because I'm going crazy.I’m trying to use SD card with STM32H747 on the M4 core using FatFS and SDMMC1 and FreeRTOS, but the MDMA write never completes and the write complete callback is never called. This happens when I try to format ...
I am having some issues with getting UART uploading working. I can read the chip and get it's ID, but it keeps saying it cannot get acknowledgments. Everything is directly connected. Serial TX/RX to their corresponding pins and RTS to Boot and DTR t...
Hi everyone,I started designing PCBs last year and have completed a few projects using Arduino and ESP32. For my new project, however, I need to use an STM32 microcontroller. I could technically use an ESP32 as well, but STM32 is more suitable for in...
Hello,I am having trouble memory mapping both OSPI ports at the same time. Can I run a QSPI Flash on OSPI1 and a OSPI Hyperbus RAM on OSPI2 and have both be memory mapped or do both OSPI ports need to be running in the same mode to be memory mapped?T...
