UM2033 mentions that Wi-fi connector of stm32f769i-discovery development board can be configured for i2c board using signals EXT_SCL and EXT_SDA that are connected to PG3 and PG6, however datasheet of MCU (DS11532) these pins do not support I2C.Is th...
HelloI'm using the latest HAL library for STM32F030. I've set up a 512 byte transmit buffer for holding bytes that are to be transmitted out the UART using DMA in circular mode. The goal is to treat this 512 byte buffer as a circular transmit queue...
Hi,Is there any one success with ESP-PSRAM64H in memory mapped mode?We are able to read ID (0x9F) in spi mode. But when we read/write, it return 0xFF. We don't see EnableWrite command, does this chip has EnableWrite command?We also wanted to use thi...
Hello, everyone! MCU: STM32F765ZIT. FLASH size: 2MB. I have a problem when running my firmware, with FreeRTOS, with or without a debugger. My code is crashing in the HAL_Init() function when nDBoot¹ is enabled. When I initialize the code through the ...
Hi.I'm trying to configure a wake-up alarm (Alarm A) to wake up (for a test) after 5 minutes, being time 0 when I turn it on, but I can't even make it work the first alarm because it keeps waking up every 30 seconds or so.I'm using the U585.Sometimes...
Hello,- STM32H743-SPI2 Slave mode, RX onlyIf the frame has the format N x data + CRC, is it possible to receive the CRC and not just the result of comparing it with the calculated CRC?Receiving a CRC does not set the RXP bit and is not entered into t...
I am using stm32l073rz neucleo board for my project.when i am trying to use uart 2 for my application, its not working as desired . That is when i connect A TTL module with the pins PA2 & PA3 on nucleo board i didn't get any output . But the same cod...
Problem: ADC reading a battery voltage jump by twice as much when the battery voltage goes from just under 3.55V to anything above (jump is about 1000 in raw adc reading at 12 bits).Background:We have a custom board with STM32G0B1CB on which we are t...
Does ST have a good default MPU configuration for the STM32H573? When I start a CubeMX project for the H7 series, it asks if I want to use a default configuration. But for the H5 it does not. While I can find forum posts regarding the need to disa...
I want to send USB HID Reports as fast as the MCU or the USB protocol allows. In order to send an USB HID Report on an STM32F103 I'm doing something like: USBD_HID_SendReport(&hUsbDeviceFS, (u8*)&report,sizeof(report)); HAL_Delay(some_delay); or even...
