Posted on April 14, 2015 at 06:06Hello, I have a stm32f429 discovery board. I am trying to confirm that I can achieve the max baud rates listed in the RM0090 document. I have tried using a pclk of 42 and 84 mhz, with oversampling of 8x and 16x. The ...
Posted on April 16, 2015 at 15:59Hi! I'm using MTF32F030R8 and I need to develope my own bootloader. I use the first 8K of flash for bootloader (from 0x800000 to 0x8001FFF) and from 0x8002000 my SW application. I'm not finding how to set the ...
Posted on April 16, 2015 at 21:53We are using LwIP running under CMSIS-RTOS and we are trying to initialize the Ethernet peripheral on an STM32F429. I have traced the problem to a line in the ST Cube code v1.5.0, in the file stm32fxx_hal_eth.c. It...
Posted on April 16, 2015 at 14:12Hello I want to measure the duty cycle of an input frequency on the stm32f4. For that I need to use the TIM3 or TIM8 and there I have to use channel CH3 and CH4. But now I'm looking for TIM_PWMIConfig(...) and there ...
