Resolved! Problem to Jump from bootloader to application on STM32F412
Good morning everyone,I am trying to modify a bootloader that is already in production and working.My problem is that if I call the JumpToApplication() function right after peripheral initialization (as the production bootloader does), everything wor...
Resolved! STM32 H5 I3C 0x7E start byte in I2C waveform
Hello,I am trying to use the I3C interface between STM32H563ZI in MB1404 board and NXP's temperature sensor P3T1085UK. I have found a question would like to be answered: Is there any way to send the IBI header (7'h7E) with SCL signal configured in I2...
STM32H563 / H573 Dual-Single SPI as a double write only master
Hi Experts,Is it possible to use STM32H5 OctoSPI interface (configured as Dual-Single-SPI) as two individual transmit-only SPI masters?Requirements:1. Two devices connected to MCU are identical but receive different data2. Devices are not a memory3. ...
Resolved! STM32F030 Halts upon enabling ADC
Hi,I am new to STM32 MCUs and working on a small project at the moment. I following the reference manual but facing an issue that as soon as I enable ADC in CR, the MCU stops responding. I have attached the following code if someone could guide on wh...
Issue with Running Application from Bootloader
I seek your assistance with an issue I'm encountering while attempting to jump from my bootloader to an application stored at a specific address in the flash memory of an STM32H723ZGT6TR microcontroller. I am able to successfully flash the applicati...
STM32 Timer PWM mode, strange behaviour
Hello!I am using a STM32F303 MCU. I am generating a complementary PWM signal with a dead time. During operation I am changing the dutycycle of the PWM. I noticed a very strange behaviour. As soon as the counter value reaches the compare value, the ou...
Resolved! HAL - Interupt-driven I2C, USART
Hi,I am new to the STM32 world and currently working on the following application on a STM32F103CBT6 @72MHz:1. Collect data from I2C sensor triggered from external interrupt @800Hz2. Read commands (MODBUS RTU) from USART and respond.I set up the uC w...
STM32F4 HAL I2C (FMPI2C) Library disable STOP after transmit
Posted on April 02, 2018 at 13:08As the title suggests, I want to modify the HAL I2C library so that after a transmit (HAL_FMPI2C_Master_Transmit), it will not generate a STOP. I think I have to modify the file stm32f4xx_hal_fmpi2c.c but I have not ...
Resolved! STM32H755 FMC LCD working on M4 core but not on M7 core
I'm using an STM43H755 (on a NUCLEO-H755ZI-Q) and I need to send pixels to an external LCD module (320x240, 8bit MCU bus on ILI9341 controller, 3.3V compatible).I've used plenty of single core MCUs like F0, F4, F7 and others from ST in the past but I...
