I have a board with the STM32F407ZGTx, which has space for an SRAM/PSRAM expansion, using IS62WV51216BLL-55TLI. I installed it, everything was fine.I worked with the old 68000 processor, which had 2 signals, UBS and LBS if I'm not mistaken. Upper Byt...
Hello,I have a problem with the STM32F103RBT6 to setup USB communication.I tried to setup it up according to this instruction: https://shawnhymel.com/1795/getting-started-with-stm32-nucleo-usb-virtual-com-port/Then I found that my MCU has a special p...
My STM32U031R8T6U (CPU: UID=0x20353953_39365013_0030007C Lot#=59S96P Wafer#=19 X=48 Y=124 FLASH=64KB) has 0xFFFF under VREFINT_CAL_ADDR - the Vrefint calibration data are absent.C code:printf("\r\n *VREFINT_CAL_ADDR=%u", *VREFINT_CAL_ADDR);Output:*VR...
Good morning,I am using an STM32G4 Nucleo-32 board (MB1430) and want to drive Relays with its GPIO; I need to know the maximum current that can give a GPIO. I searched on the datasheet of the STM32G431x6 , the maximum power that can be delivered, but...
I am working on a project with the STM32G0 series microcontroller. There is a requirement in my project to identify a BOR (Brown-Out Reset) independently. In the previous version of the project, we used the STM32L4 series, where there is a reset flag...
IssueHigher ambient temperatures cause communication malfunctions with XSPI memories.DetailsOur design is heavily adopted from STM32H7S78-DK which also has the same issue described below.The application uses memory-mapped mode for both Flash and RAM ...
Hello,i have a question concerning the SD-Card functionality and the licensee fee of the SDMMC implementation of the STM32H723ZG.My goal is to log some data on the card. According to the documentation, the FatFs-Filesystem can be used under a BSD-sty...
Hello,According to the documentation, the FatFs-Filesystem can be used under a BSD-style license. How About the exFAT licence fee. Has this fee already been paid with the purchase of the STM32?
Hi there,There are a few projects where having a 16bit DAC instead of a 12bit DAC would be extremely useful.I am currently using the G4 series as analog synthesizer controllers and it would be fantastic to be able to use the 1MHz DAC as a 16bit audio...
Hello,We are working on an induction heater design using an STM32G4 MCU, where we need to measure the coil current via the ADC. The system operates with a half-bridge switching frequency of 30kHz.At lower frequencies, the current waveform is triangul...
