How to connect 8 SDRAMs 512Mbit each, in the FMC of an STM32H7?
Hi!I’m developing a board with the STM32H755XIH3 and I need to increase the RAM memory, so I pretend to use the FMC, but the thing is that I will need 4Gbit of capacity, which I think is the maximum capacity available for the FMC, so I select an SDRA...
Resolved! What is the purpose of the PMOS switch for VBAT-SYSTEM STM32L0x1 see AN4718
AN4718 "How to design a V BAT system based onSTM32L0/L1 ..."Case 1b, it is stated, quote:"V DD /V DDA can also be switched to V BACKUP when STM32L0/STM32L1 MCU goes into STOP mode, to allow user to remove main supply in very safe way."End quote.Quest...
Resolved! STM32H723 Custom Board - St-Link V2 very slow
Hello,After prototyping with a Nucleo H7 board, I'm setting now up a custom board with a STM32H723ZGT6 MCU (the same MCU present on the Nucleo).I connected my USB Dongle ST-Link V2 via SWD to program the MCU and after having struggled a bit, I have f...
Resolved! Hello, I'm begginner on stm32 and i try to program, without succes, a VCP on NucleoBoard L152re.
My code is simply :HAL_Delay(100); HAL_GPIO_TogglePin(GPIOA,GPIO_PIN_5); uint8_t buffer[] = "Hello, World!\r\n"; CDC_Transmit_FS(buffer, sizeof(buffer));But nothing...> The led is blinking.> The VCp is define via *.IOC with no error.> Comp...
Doubts on Nucleo-H753ZI
I'm interfacing Nucleo-H753ZI with DAC8775EVM through SPI4. DAC8775EVM works on logic HI in range of 5V and expects the same logic from Nucleo-H753ZIbut Nucleo-H753ZI MCU itself runs at 3.6V so Logic Hi isn't read by DAC8775EVM.How to Change the logi...
Resolved! Explain how part of the circuit works with operation amplifier on board B-G431B-ESC1
Hello.I will try undestand how work plate 'B-G431B-ESC1', more precisely schema operational amplifier (on image).I have not understood, what does resistors R1, R2, R3 need on cicuit with getting current from shunt? What is the idea behind their work?...
STM32H743ZI2 NUCLEO board Ethernet doesn't work when moving to JP5 to 1.8V (MCU_VDD)
Hi All,I use the STM32H743ZI2-NUCLEO board with JP5 on 1.8V for MCU_VDD.Running the LWIP example, the Ethernet doesn't work (It does work when running with 3.3V).Any idea how to make it work with 1.8V?Thanks,David
Resolved! How to download ST-LINK V2.J32.S7 firmware
Hello. We are working on a project that uses STM32H747 dual-core MCU.The ST-Link firmware is updated to the latest version, so debugging is not working well.So I'm going to lower it to the version I used before, but I can't download it. The lowest av...
STM32F446RE Schematic Diagram
Hi, I am looking for STM32F446RE Schematic Diagram. Can any Help me, where to find the Schematic Diagram of STM32F446RE, I have checked the documents of ST(https://www.st.com/en/microcontrollers-microprocessors/stm32f446re.html#documentation) I did n...
STM32F405: Can we use Port A0 (T2.1-ETR or T8 ETR) to trigger a capture on Port A5 (T2.1-ETR or T8.1)?
When we enable the RTC feature on our controllers, we do a calibration in Production against a GPS-locked 10MHz signal. Usually, we'll use the T2 ETR to clock the 10MHz signal in and an RTC-generated 1Hz signal on one of the other T2 channels such a...
