I'm using a STM32G070 MCU which I flash via i2c when the boot0 pin is set to high. This works fine until I connect a ST-link to the MCU, program it and then disconnect the ST-link again. After that the i2c flash will fail, I have checked the boot0 an...
Hi, I need some help with designing an oscillator for an STM32, I have some questions:1. I use the 32KHz oscillator only for the watchdog, so I don't need much precision, but is it still necessary or advisable to use an external crystal or is th...
Hello?We are reviewing a high-speed USB communication interface that connects to the STM32H7 series.Among the currently commercialized products, there seem to be about three that are used a lot, but there is no choice.First is the STUPLI01 (made by S...
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...
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...
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...
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...
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...
