I want to drive havfbridge with STM32G474. I am going to use TIMx with channel1 and channel2 to create two PWM signals, that are 180° out of phase and with the same PWM % that is limited to 0% < PWM % < 49%. Because tohose signals have max 50% duty c...
Option 1:- Use a 10MHz Timepulse signal from the GPS (Ublox M8N) and connect it to the STM32H7.- The STM32H7 will count the timer from 0 to 999999.- To determine when the second has passed and the NMEA signal arrives, check the next timer overflow, w...
Dear sir, dear missis,I'm working with an STM32L053r8 on a step by step know-how. My interface with the bootloader runs fine, and I am able to cover the main features provided through this interface. The issues I try to cover now is the right underst...
I initialize RTC timer by first clearing RTC_CR register,then waiting until WUTWF bit is on, then setting RTC WUTR register to 100, and RTC_CR to 0x4420 (wakeup timer enable, wakeup interrupt enable, bypass shadow). Bypass shadow register is set for ...
Hi Team, We are working on STM32U5A9J-DK for one of our application interfaced with Octal SPI Flash.We needed to acheive RWW operation which is supported by our Flash chip and we have used OSPI1 and OSPI2 in multiplexed mode but we are controlling Ch...
I am using this dev board: NUCLEO-F411RE for developing SPI communication protocol considering it as a SLAVE device. My firmware will receive data over SPI sent by Host machine and acts on it.I have following requirement:How to transmit data packets ...
As described in RM0444I understand my virgin device (STM32G030C6T6) should to connect via UART using STM32CubeProgrammer but as shown I'm not able to establish the first transaction (byte 0x7F reception and answer)I've checked my custom board hardwar...
Hi,While working with RTC smooth calibration on a STM32G070 part, I noticed two strange things:1st strange thing: When RTC_OUT pin is only driven with the battery backup (no main power) I got 512.18 Hz; however, when the main power is restablished, t...
Hello,I was able to update F429 using boot-0 and CubeProg tool via USB. But requirement was to update without boot-0 pin. Please suggest alternatives for update from USB.Also wanted to know: I tried changing boot-0 to do DFU, using SW and HW reset bu...
Hello, I want to ask what is necessary for implementation of 32.768khz RTC XTAL to STM32F411CEU6?In AN3060 I saw in chapter 3, fig6 that external load caps are not needed because they are implemented in STM32 MCU. Then I checked STM32F411CEU6 datashe...
