I wanted to use RTC in both my cores M7 and M4. Is RTC a shared peripheral ? Can we use RTC to set or get time from any core asynchronously ? Please share any configuration need to be done for doing so ?
I'm configuring I2C4 as a slave receiver, using interrupt method. I noticed that when the I2C master (another MCU) sends the slave address, I2C4 detects an address match and sets the ADDR flag in the I2C4->ISR register. What baffles me is that at thi...
Hi,I configure the ADC as the following code; but sometimes(not everytime) the code will run to Line 70 : "Beer_Out_Dis(1);" ,and ADC will not work.Did I do something wrong? Thanks verymuch./* ADC1 init function */ static void MX_ADC1_Init(void) { ...
This is just a test. Has anybody else been unable to submit questions? I keep getting a red error message.
In my design, I have two MCUs, the STM32F103RCT6 and an ESP32. At some point, the ESP32 will perform a firmware update of the STM32. So it will need to reset it through the NRST pin, controlled through a GPIO. I have checked rapidly the datasheet, th...

There is a point that confuses me, I am reading from the datasheet, but I wanted to ask some questions.For stm32f4, there is FB_MODE bit in the SYSCFG register (8th bit), if the FB_MODE bit is 0, the address 0x08000000 becomes BANK1, if it is 1, the ...
Why the operating frequency of ATM32H7A3/7B3 is limited to 280 whereas the other families in H7 series supports minimum of 480MHz
Hi all,I'm working on an STM32L552E-EV and trying to declare some constant data into the NOR Flash connected on the Octo-SPI interface. I want to have the Octo-SPI in memory-mapped, so that the constant arrays can be accessed easily in my code. To in...
Hi,We are using the OCTOSPI2 on a H735 in memory map mode.We are copying 32 bits values one by one, from the internal RAM to the Octo memory.We transfer around 5000 x 32 bits in 2ms which is around 10MB/s.I think, it is a bit slow. What is the maximu...
