On initiating I²C communication, status register SR1 gets reset immediately
With the following code to handshake an EEPROM STM_enableRCCAPB1PeriphClock( RCC_APB1Periph_I2C1, ENABLE ); STM_resetRCCAPB1PeriphCmd( RCC_APB1Periph_I2C1, DISABLE ); I2C_Cmd( m_pEE_I2C_TYPE, ENABLE ); I2C_ITConfig( m_pEE_I2C_TYPE, I2C_IT_ERR, ENABLE...
Resolved! Write firmware to an STM32 via CAN
Hello community members. I would like to know if it is possible to write firmware to an STM32 via CAN bus?I intend to implement something for this purpose.
Help debugging HardFault on STM32F446 using STM32CubeIDE
I have an application running on an ST32F446 using code generated by STM32CubeMX. I use SPI1 in slave mode to receive commands, and have FATFS operating with USB HOST to connect to a USB FLASH drive. I can send commands via the SPI interface to open ...
Only single ADC in F401 and F411
This is not a question, more like a statement and proposal to update datasheet.In these two datasheet:DS9716, STM32F401xB STM32F401xC, DS9716 Rev 11, page 105/139DS10314, STM32F411xC STM32F411xE, DocID026289 Rev 7, page 114/149It are specified sample...
STM32L4S5VIT - Create a muxed PSRAM by using a standard PSRAM.
Hello, I am using STM32L4S5VIT in LQFP100 package, i want to control a non-muxed PSRAM Memory of 64Mb (ref: IS66WVE4M16EBLL-70BLI) by FMC bus.The problem is that the MCU have just the Muxed Mode as shown below :Can i add a multiplexer to connect betw...
Problem with two simmilar projects
Greetings everyone!Lately, I have generated two projects for Nucleo-STM32H745ZI EvB.The first one was generated just for the MCU and for the second one I have chosen the EvB as a reference. So now I do have two quite simmilar projects where the first...
Resolved! Can dual circular DMA buffer be implemented on a single RX USART?
Hi everyoneI was wondering if it would be possible to implement a DMA setup without interrupts that maintains two circular buffers for the same USART? I would like to save both the SR and DR register values in two separate circular buffers every time...
STM32H7 Huge program with UART Tx using DMA
Hey guys!This probably came up 5000 times, however I did try to look for a solution before I ask this one. Couldn't find one.I am having issues transmitting data via uart with DMA.Problem:The problems I am having is that the RxBuffer is not receiving...
