Posted on September 04, 2017 at 15:45Hi.I bought 2 eval boards STM32F429I-DISC1 and STM32F10x-DISC1 and found STM32F10x_StdPeriph_Lib_V3.5.0 of STM32F10x.But I'd like to get STM32F4x SPL file not en.stsw-stm32054.zip STM32F10x_StdPeriph_Lib_V3.5.0...
Posted on September 04, 2017 at 05:42HI.Currently I'm trying to understand about STM32F10x's interrupt.So I've got some snippet code as the below,USART1's IRQ number is 37.// interrupt example snippet code //unsigned int vector_table_start_addr = *(...
Posted on August 31, 2017 at 16:29Hello to all, I need to write the bootloader for a cortex M0. Could someone explain to me what I have to do. What are the code that I have to write and how I have to modify the linker and the sturtup .s file? In the...
Posted on September 04, 2017 at 09:49In AN2784:Using the high-density STM32F10xxx FSMC peripheral to drive external memories.There is a rule:tsu(Data_NE) + tv(A_NE)=2tHCLK + 25. I use STM32F207 on my board. What is the value of tsu(Data_NE) + tv(A_N...
Posted on September 04, 2017 at 09:44Hi.I have enabled MPU for different regions with different attrubutes (mainly read only, execute never and no access attributes). For peripherals region I enabled also bufferable attribute (MPU overrides global w...
Posted on September 04, 2017 at 09:19Hi everyoneI'm on a project where i need to create 300 us pulses every 1s so i need 100000 samples on my DAC, but the RAM is not enough to handle with that number of samples. The thing is the pulse information is...
