We have a STM32H745 MCU, an IS45S16320F SDRAM on the FMC interface, which is used for a Codesys application code execution.This is the SDRAM init:/** Perform the SDRAM1 memory initialization sequence */ hsdram1.Instance = FMC_SDRAM_DEVICE; /* hsd...
I'm using LC709203F to measure RSOC. It is going to sleep mode after 1.2 Ms.To wake up from sleep mode , I have write 0x0001 to register 0x15 in fuel gauge.Prior to that , I have to set SDA line to low for particular time.Please help me to set SDA li...
I need to feed STM32F427 with external clock generator and at the same time use PH1/OSC_OUT pin as GPIO output.What I doing.STM32CubeMX 6.3.0, FW_F4 v1.26.2 Firmware, "Pinout & Configuration" TAB -> Categories -> RCC -> High Speed Clock (HSE) BYPASS ...
I setup my custom board with STM32F401RE. I am using the HSI a the moment with configuration shown in the image below. All I am doing is printing some lines using this function on the UART2:#ifdef __GNUC__ /* With GCC, small printf (option LD Linke...
I want to use ADC for audio conversion. I have an ADC which is triggered by timer with the freq of 8kHz. Then on EXTI the ADC-DMA channel starts. It have to transfer samples to buffer circularly and when half or full transfer complete IRQ appear, the...
I'm working with an external loader. I choose it from debug config and save my images to the qspi flash. However, everytime I debug my code, do I have to save images to the qspi flash again and again?
I am working with the STM32 Nucleo-64 development board, which has an STM32L476R microcontroller. My SystemCoreClock is 16 MHz and TIM17 is clocked at 4 MHz. To my surprise, the code below only works well (the timer doesn't miss the next interrupt an...
I have my own board and it wants to take >20mA at 3V3. I don't want to increase the current limit if there's a short, but I don't know what it needs. What sort of current should I expect before I program it? Thanks
i want to interface shift register(74HC595) with STM32F103C8T6 MCU using SPI Transmit only master mode.I need to continuously write shift register so it is continuously update op pins. so i set SPI DMA in circular mode and when transmit complete i ne...
