Hi Community,I am using STM32H747I-DISCO board, I'd like to use 2 FDCAN but I can only find PA11 and PA12 on STMod+ connector for FDCAN1, seem like all of the FDCAN2 pins are not available but I'm not sure.Could you please help to find out ?By the wa...
I am using STM32H7 family of microcontroller as SPI Master Transmit device which needs to talk to 4 SPI slave devices receive only which are also all STM32H7 MCU's. Both master and slave are configured for software slave management. The confusion is ...
How can I avoid this?
Dear all,I am in difficulty to adjust Timer 3. Let me explain with examples:Internal Clock is 72 MHz and it is used for also Timer 3 as an input clock.1- When PSC: 36 and ARR: 124 it should generate an interrupt every 62,5 us (we can assume it genera...
Hi people.I have a circuit which must enables an LDO by pressing a button which applies 4.2~3.7V to EN pin of regulator. after enabling LDO, MCU (which is from F0 series) powers on and takes control of LDO EN pin by applying a HIGH output on EN pin w...
Hello!I am trying to generate COMP2 interrupt on the rising edge on Input[+] of COMP2.Input[-] is conected to ground and Input[+] is connected to pull down resistor.What is strange that interrupt is generated only when Input[+] is connected to ground...
