When I read the datasheet, the introduction doesn't mention the number number of cores. Digikey says this is a multicore chip. Mouser doesn't either talk about multicore.Several pages down (14) on the datasheet I can read that this is indeed a multic...
I am developing an audio processor product that requires 8 audio output channels. I intended to use I2S2 and I2S3 for 4 stereo Tx pairs. The other I2S interfaces are used for other functions including audio input channels.I had to work around the H...
Hi,I am using Standby mode on STM32F446ZE, but I faced with a problem. Sometimes MCU doesn't enter in this mode. Exiting Standby mode via RTC wakeup.Below is present steps which I perform for entering StandbySCB->SCR |= 0x00000004;PWR->CR |= 0x000000...
Hi all,I am capturing 10 pwm pulses from proximity sensors by making the all pwm pins in rising falling interrupt mode.PWM is captured by a timer at every 100us interrupt.some times pulses are missing, I don't know why this is happening.I am sharing ...
Hi there this is Akash, I am doing a project on STM32F100RB Discovery Kit, in this project I am controlling stepper motor with some parameter given by the user using rotary encoder, basically I want to run the motor in the while loop, and through ext...
Is there a limit on how many bytes to send over I2C from the slave?The MCU in question is STM32F469NI, and I have programed the board to act as an slave using HAL, it works fine if amount of data sent from slave is less than 100, but gets corrupted f...
Hi,I'm trying to use the QSPI peripheral on the STM32F746, specifically on the STM32F746 Discovery board, however, as soon as any QSPI interrupt is enabled there is an interrupt present but upon reading the status registers there is no visible interr...
Hi, I designed my first own board with a STM32F030F4P6 on it. Additionally a got me a ST-Link V2 for programing and debugging. As IDEIuse CubeMXIDE. I already successfully programed some Nucleos with it. With my own board I don't get a connection to ...
HI!I am currently trying to minimise the standby consumption of a STM32H7 down to theabsolute minimum. Only the change of one Pin (PA0) is selected as wakeup event. No need for backup ram, Pin drivers, RTC nor anything else. The MCU shall only switch...
I want to periodically check the state of the RAM ECC detection in my firmware on a STM32H753.The ECC mechanism is well described in the Reference Manual for the Flash but not very well (in my opinion) for the RAM.I've seen that there are dedicated i...
