GPIO toggle, uneven high and low.
Posted on December 09, 2011 at 14:39Hi, I want to measure the clock of my stm32f225rg chip. I am doing it by toggling the bit of gpio port B and checking using scope. Rather than using the routines in the standard peripheral library, I am programm...
Setting up the Clock for HSE 16mhz and usart2 baudrate is lower as configured
Posted on December 06, 2011 at 21:27hi, I have a stm32f103zet6 board and im using keil. the external crystal (HSE) has 16mhz. When im setting up my USART2 @ 38400bau in Keil Debugger it shows me that its running with 12668 baud ??? (=38400/3,19). ...
Possible to avoid FLASH_Erase() stall on stm32f103?
Posted on December 08, 2011 at 20:04Hi, I'm using ADC with DMA and periodically erasing the flash pages. But the dma interrupt is not fired while i'm erasing the flash pages. I'm also using a lot of flash constants in my code. Is it possible to avo...
Listening SPI communication between two ICs
Posted on December 08, 2011 at 22:01hi everyone,Two boards communicate via SPI, I try to read what master sends to slave and what slave responds with my STM32 eval board.I simply connected 3 wires to CLK, CS and MOSI lines of master IC to three GPIO...
STM32F1/F4 incompatible I/O
Posted on December 08, 2011 at 19:32From their respective RMs: STM32F1... 0x4002 2000 - 0x4002 23FF Flash memory interface STM32F4... 0x4002 2000 - 0x4002 23FF GPIOI Thus a project predicated on STM32x compatibility must have at least different I/O ...
