Hello,should LSERDY assert with LSEBYP?I have a SIT1533 (32.768 khz Mems ocsillator) connected to PC14/OSC32IN on a L412. I first reset the backup domain, than I enable LSEBYP and with next command I enable LSEON. On a cold start, where the SIT1533 m...
On the STM32L072 series, the reset state of all the pins are "Analog mode", except for PA4, PA13 (SWDIO) and PA14 (SWCLK).When I put the STM32 into STOP mode, PA4 (configured as an input) causes the current consumption to increase by ~10uA. When I co...
Hi,I am working on the STM32F030C6 MCU to develop the alarm Buzzer tone generation.I need to buzz the buzzer with different melody tones and also need to control it Volume.Can anyone please share and suggest me how do we achieve the above functionali...
In the manual, it states that it is better to change an input pin to analog to disable the Schmidt trigger input current consumption during STOP mode. How much does this save? Should the pull-up / pull-down be disabled too?If a GPIO pin is configured...
What is the best way to set up FD CAN in classic mode on stm32 nucleo h743zi board?Currently, I'm using FDCAN with 16 Mhz frequency on the bus and I want to get 500kbit/s.My settings are:hfdcan1.Init.NominalPrescaler=2;hfdcan1.Init.NominalSyncJumpWid...
I'm toggling an I/O in the SYSTICK interrupt every 0.5 seconds with the processor running at 168MHz and using an RTC interrupt to wake the CPU from sleep. This all works well and the processor wakes up after the programmed interval. As per the HAL ...
Hi All,I need to enable interrupt on GPIO PC0 only for 1sec: before and later interrupt form PC0 must be ignored.I've tried with disable the interrupt at the init and enable in a thread, wait for 1 sec and then disable again, but it doesn't work!stat...
I'm evaluating the STM32H742x and its cousins. My design has four identical high bandwidth SPI based analog front-end peripherals, each peripheral with its own MOSI and MISO. I would like to command them with in a concurrent fashion (analogous to SIM...
I am reading the example code F303C_EVAL / F303E_EVAL and I don't understand it.Why is stereo half of total size?
In the datasheet for STM32F4 https://www.st.com/resource/en/datasheet/stm32f413cg.pdf, the first page says “Up to 109 fast I/Os up to 100Mhz�? and Block diagram on page 18 shows AHB 1 bus 100MHz connecting to GPIO ports. Whereas in STMf2 https://www....
