HAL_I2C_Mem_Read(I2C_HandleTypeDef, Address, REGUSTER, rsz, buff, bsz, tout);If the device address is 0x77,what is th proper way. I can find non consistent answers, though i cannot read. I get HAL_ERORis it:Anyway each option returns non consistent d...
Hi,I suspect that I encountered with undocumented silicon error of STM32L432KC, while I'm playing with a Nucleo32-L432KC board. Here is how to reproduce it:Start a new project with CubeMX v.4.27.0Select SPI1 as a full duplex master(PA1:SCK, PA6:MISO,...
Is there a way to retrieve the value APBx timer clocks are set to?I have found functions to get the PCLK1 and PCLK2 frequencies but there is a multiplier that can change the final timer clock so that is not reliable.
I am able to receive only 0x0D in receive buffer, but I can see different data in Receive string.Please can someone help me..unsigned char i = 0, k = 0; //HAL_GPIO_WritePin(GPIOC, GPIO_PIN_2, GPIO_PIN_SET); //Switch ON GSM LDO __HAL_UART_ENABLE_IT(&h...
Hello.I want to use AS4C8M32SA-6BIN ( https://www.alliancememory.com/wp-content/uploads/pdf/dram/Alliance%20Memory_256M%20SDRAM_AS4C8M32SA-6_7BIN(BCN)%20A%20die_rev%201.0%20November%202016.pdf )But I can't pick up the settings.The names in HAL and th...
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...
