Resolved! STM32H503 OTP BUG
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...
Resolved! STM32L412KBU3 DFU
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...
question about STM32G474 dual banks
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...
STM32H503 UART bootloader read protection
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...
STM32H753 ADC calibration after being disabled for an extended period of time
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!
STM32H7B0 has incorrect ADC scale
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 ...
Resolved! Correct data is intreppted by STM32F0 from UART even when paity is wrong.
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...
Resolved! First ISR of the timer is exected even after it is reset
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...
Please make infographics usable again
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...
