I want to know what kind of value we fill in this and what affects the AHB Bus please make me understand.const uint8_t AHBPrescTable[16] = {0, 0, 0, 0, 0, 0, 0, 0, 1, 2, 3, 4, 6, 7, 8, 9};I tried to find out but only figured out the value of 1 to 9 i...
"I'll delete this question once someone answers it, as it is not relevant".Why in second line did some one write ch & 0xFF? ch limits are already 0 to 255 right?
Application needs to use all three (in STM32G431) op amps as inverting PGA handling ac-coupled signals. As there's no internal option to supply mid-point (VREF/2 with a decoupling cap at the device pin) to the non-inverting inputs of the (3) op amps ...
Hi, i have a sensor that generates a TTL signal. I need a couple Pwm signal by using this external signal which is my master. I have Stm32f4 discovery MCU . Is there any way to do this goal. Please help me with any code sample or documents.
Hi,I am using STM32F413 Nucleo board. I am using MDK5 IDE and HAL libraries. I made an example for reading/writing internal flash based upon a cube project. The idea is to erase interal flash and then to write some data to it. I alreay did some simil...
If FLASH register's offset[ex:FLASH_OPTR offset:0x020] refers from the userspace address of Flash memory,writing the user code in flash memory starting address [0x08000000] will overwrite the existing flash registers data?
Hi, I have my PCB that have a processor used as host and STM32U5 (STM32U585AII6Q) used as low power MCU. USART connection is between host and STM32U5.When I enter Stop3 low power mode, and host is turned off, there is a problem with current on USART ...
Hi All,I have an application running on STM32F439 based controller board. And I am planning to use external SRAM.I wanted to know, how we can protect the data in external SRAM ?Or any suggestion on using external SRAM with assumption of security.Than...
I am writing a Programm on stm32cubeide. But during Debugging and Running the Programm, I habe the error Break at address "0xfffffffe" with no debug information available, or outside of program code.I don't know what it means and can I handle with th...
I have read previous posts ,,,I set up dma to read adc ,Although dma's destination address is allocated from AXI RAM, dma does not work when d cache is active.Can anyone share detailed information or a sample code about this?
