I've been reviewing AN5027 (Interfacing PDM digital microphones using STM32) and am a little unclear about a 4x2ch mic configuration using 4 of the SPI/I2S peripherals available on the F412.Looking at the figure below, could I connect all 4 stereo pa...
Posted on March 07, 2018 at 13:57My hardware is STM32F429ZI6 and LCD.External ram or etc no other hardware.Is fsmc and fmc different?Is that valid this data for the command stm32f429?#define LCD_REG (*((volatile unsigned short *) 0x60000000)) #defi...
I have LCD connected to FSMC, 16bit parallel interface.It works, but all signals are twice slower.SYSCLK is 120MHz (checked using MCO), HCLK divider is 1 (checked with debugger).Timers TIM2, TIM3 and TIM4 give expected results, so the system clocks ...
I am using STM32F030K6T6. My project is a 433MHz one way data link. The RF receiver blocked from the radiated noise of STM32. So, the distance is reduced between the link. In order to make it work, RF receiver and STM32 have to be at least 5 inch far...
Posted on June 21, 2018 at 18:10Hi, I've got a strange problem when generate the bin file from my project. I'm using atollic true studio and then generate the file the dimension are too hi! Anyone have any suggestion?See attached imageThanks
Hello guys.I have two int variables in my application and need to save them. Somebody told me that you can do this by software that is called EEPROM emulation. I searched what it is and I'm confused.Can anyone help me do it step by step? (If you can ...
I am working on a project based on stm32f429 chip. I made the project using CubeMX and added RTX codes. and made changes like this link:https://www.keil.com/pack/doc/STM32Cube/General/html/cubemx__r_t_x.htmlBut still it doesnt work...What is the prob...
Posted on June 25, 2018 at 12:17Hi,Today I tried the STM example (see below path) of low power stop mode on my STM32L053, While stepping trough the code in debug mode, somewhere in SystemPower_Config(), line 237, HAL_GPIO_Init(...) the connection wi...
Before you say it, I know dynamic allocation is usually a bad idea with embedded software, this is more of a technical question. If I create a new blank C++ project based on my Nucleo-L152RE in SW4STM32, the "text" portion of my compiled project read...
Hi,I'm working with CubeMX (V4.27) on a STM32F205RBT6 (Cortex M3, Firmware Version: V1.7.0) and Atollic True Studio. When I generate a code leaving everything on default settings, the MCU will hang in an infinite loop once it calls HAL_Delay() becaus...
