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...
Currently, I have a project using a secure application for the STM32N6570-DK. I am able to run and debug the FSBL and Application with the system in Dev Boot, but have yet to be able to attach and debug when booting from the external flash (Boot1 and...
Hello,I am trying to implment MODBUS Slave RTU with STM32F030C8T6. I havce used RS485 for physical layer for communication.As per MODBUS protocol, a stream of 8 bit data will be sent from Master. As a first step slave must capture all the data in an...
In order to make informed decisions on chosing a mcu model, we need... well... information.The older STM32-family infographics contained a fair amount of information about what to expect in terms of available peripheral mix from a given family and it...
