Target not detected via STlink V2 ISOL
I am utilizing the STM32F767Zi microcontroller unit (MCU) on a customized printed circuit board (PCB). During the debugging process, we are using the ST-Link V2 ISOL debugger. However, we are encountering an issue where the MCU is not being detected ...
Half bridge, complementary outputs and dead-time insertion
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...
I want to create a highly accurate GPS time synchronizer.
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...
Resolved! Debug port
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...
STM32L452 RTC wakeup timer works, but just once
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 ...
Read While Write in STM32U5A9J-DK
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...
Resolved! How to test STM32 MCU SPI communication using Host PC ?
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 ...
cannot communicate STM32CubeProgrammer with STM32G030 ST Embedded bootloader
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...
RTC_OUT pin on G070 gives different frequencies when I attached it a multimeter (or 10K resistor)
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...
