STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
The FRAM chip I'm using is cypress.For details, here's a screenshot of my chat with Cypress.Thank you very much.
I am currently experimenting with programming flash memory. I want to figure out how many sectors to erase before writing data into memory. I came across the following snippet uint32_t Flash_Write_Data (uint32_t StartSectorAddress, uint32_t *Data, ui...
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？
