I was going through embedded flash programming documentation of STM32F7 . I came across a term called "data read width". can some one explain this term ?Flash memory single bank organization (256 bits read width)Flash memory dual bank organization (1...
For a long time I have been trying to guess how debug components are connected to the Cortex-M7 core in STM32F7 series of microcontrollers. It is supposed to be shown in e.g. the document RM0410 in Figure 587. This figure seems to be a copy of the sa...
The server connects and communicates normally, and the Client experiences a return value = -13, Abort in the connect function.Using the Netconn API, the user program is hercles_3-2-8.exe. PC IP is 192.168.0.223 and Device IP is 192.168.0.222.The code...
There is a misprint in your PM0214 Programming manual "The Cortex M4 processor" in the chapter chapter 2.2.5 "Bit-Banding", above figure 9. Bit-Banding is nicely described there, but of course all bit addresses have to end by "00"... Your first exam...
I have a bug in the I2C bus where sometimes a glitch causes the BUSY flag to be setI found that the only ways to clear it is either by SWRST in I2C->CR1 or by resetting in RCC->ABP1RSTR->I2CxRSTRMy question is, is there any difference I should know a...
For STM32F4 series, when PC14/PC is used for external crystal(32.768k), which power supply is output for crystal? What is the voltage amplitude？
Board Name : STM32F746NG discovery boardI have created the section for QUADSPI & SDRAM in linker fileMEMORY { RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 320K FLASH (rx) : ORIGIN = 0x8000000, LENGTH = 1024K QUADSPI (rx) : ORIGIN = 0x90000...
I work on basic i2c example with DMA using HAL library. When i observed data in the debug section that data read correctly but DMA did not rise flag TCIF(transfer complete flag). What might be reason ?void DMA1_Channel1_IRQHandler(void) { if(__HAL_D...
In powerstep01, voltage mode is more preferable for lower speed while current mode is more suitable for higher speed. Do anyone know what is the reason ?
