Stm32F3xx Flash read and write uses but focussed around byte size operations
Hi ,I ma looking at using the internal flash for EEPROM emulation, using Atolic and STM32F302ccI have read the aplication note on eeprom emulation and quite a few stackoverflow discussion as well as a few ST community posts which seems to focus arou...
I2S on STM32F446ZE micro controller to check(test) microsemi ZL38063
Here I am trying to generate a simple example of sine wave to pass over I2S and just send the data on ZL38063(slave) using STM32F446ZE . Clock is working fine @1.5Mhz and WS @48Khz and also getting PWM data on SD line. I am not able to hear any kind ...
Resolved! STM32F429 and Controlling a timer to control another timer that is a one shot to update the internal DAC.
I am trying to set up a timer go to a one shot timer that goes to the DAC update command (to output data that was written via DMA). I am little confused on how to set everything up. I want to set up timer 1 to go to timer 2 and timer 2 will be a one ...

Resolved! ST-Link Utility bug in V4.2.0
I Previously used V4.0.0 (At least I think so) but sometime ago upgraded to V4.2.0. Now every second time I read a .hex from disk it crashes (having programmed the chip between file openings). The .hex is for a stm32H7 (doesn´t know if it makes a dif...
stm32f091 rtc error
Hi. As you can see in the picture I haven't got the LSE crystal resonator so I have 40 Khz as RTC input. The datetime is not well calculated.How can I resolve the problem? Is there a way to have an affidable rtc whitout the resonator?
