Using single Timer to output several PWM on different channels with different frequencies
Hi guys I am a beginner of STM32 user. Now I am learning PWM. I wanted to make use of a single Timer and use 2 or 3 of its channels to output PWMs of different frequencies. I saw AN2581 app notes but unfortunately there were no sample codes there. W...
Resolved! I2C and SPI at the same time?
Hi. I'm not a English speaker. Sorry for my poor English.My code including EITHER I2C or SPI works successfully on STM32F303K8T6 Nucleo Board. However, with my code including BOTH I2C and SPI , Only SPI functions work correctly ,but I2Cs don't.Usin...

UART Bootloader
I am trying to flash the memory of the STM32-L43KC (Nucleo-32) MCU with the UART Bootloader. I have connected the TX and RX pins of the board to FTDI USB-RS232 connecter. To boot from the system memory, I have also configured the option bytes accordi...
On chip temperature sensing dependant on Vref
The reference manual documentation for the onboard temperature sensor for STM32H745, RM0399, chapter 26.4.33 gives a formula for calculating temperature that is only valid when VREF is 3.3 volts, but lacks mention, foot note, etc of any kind that VRE...
ADC
I am using NUCLEO-G071RB. I use 2 ADC channels: GPIO analog and internal temperature sensor. I connect the +3.3V to the GPIO analog pin via. potentiometer. The internal temperature looks like it works well (the temperature rises slightly when I put a...

Request for explanations regarding the ICACHE of H5
Using an STM32H5 I recently came across a problem: triggering a hard fault when accessing data in FLASH (read FLASHSIZE_BASE).It turns out in this thread that the ICACHE being validated, it is necessary to configure the MPU to make “uncacheable” the ...
