Hello everyone, I encountered a problem with overwriting OTP memory both from a user application and from the stm32 programmer.I write data to the OTP cell, close the memory using standard hal functions, turn off the power of the debug board, turn on...
I am currently trying to use the LCD screen of the STM32N6570DK development board. But when I integrate the relevant information from the official firmware package into my project and try to use CUBEIDE for DEBUG, an error message will appear like th...
Hello Guys,I have a STM32H743IIT6 on a CustomBoard, my Clock is a Quarzoscillator with 25mhz. I have a SDRAM from Winbond with 32 MiB on Bank1, my debug port is USART2, with sdcard for linux later.I checked out the last release of u-boot from https:/...
Need some clarification on implementing the DFU functionality on STM32L412KBU3.According to the note in AN2606 (page 350), it states: "VDDUSB IO must be connected to 3.3 V" however, on the STM32L412KBU3 (UFQFPN32) the VDDUSB pin does not exist.Curren...
I have a test question about STM32G474 dual banks to ask :A test program for LED flashing has been successfully constructed in the IAR environment.Use STM32CubeProgrammer to load BANK1 starting from 0X8000000, DBANK=1,BFB2=0, and the program runs OKW...
Hello everyone, please advise, I encountered difficulties when removing and installing memory read protection when programming h503 via the built-in UART bootloader.I use commands {0x92, 0x6D} to remove read protection and {0x82, 0x7D} to install rea...
Hi,In the STM32H753 reference manual revision 7 ADC section 25.4.8 page 932, there is a statement about ADC calibration:Anyone know what the extended period is that I should worry about? Thanks!
Dear,We are using the ADC2 in 16-bit resolution at 100 kHz, operating in differential mode.The internal voltage reference (Vref) is set to 2.5 V.A 1 kHz sine wave with a peak-to-peak voltage of 2.5 V (ranging from 0 V to 2.5 V) is applied to the ADC ...
IS61WV25616MEBLL and IS64WV25616MEBLL are recent Muxed PSRAM from ISSI. I would like to use these with an LQFN100 STM32H750VBTx to avoid complicated routing with SRAM and going to a larger LQFN or BGA package.The FMC of this MCU supports Muxed PSRAM....
Hi, with STM32F030C8T6, I am implemeting MODBUS protocol in RTU (Slave) with UART as physicsl layer. I use QModMaster (A master simulation software run in PC). I use oscilloscope to probe the actual information through the RS485.Recently I inplemente...
