Posted on August 30, 2013 at 03:17hi guys i'm new to stm32, i got a problem that i used sdio and fatfs to test maximum speed of write sd card, its only around 330kb/s but when i try to use sd card reader its up to 2mb/s, so i want to figure out why ...
Posted on September 04, 2013 at 18:14I'm trying to flash a custom bootloader to one of these devices: http://www.mikroe.com/mini/stm32/, and they seem to have protected their bootloader. I'm using an STM34F4discovery board for SWD, and OpenOCD (0.7...
Posted on September 04, 2013 at 22:45Hello everyone, I'm trying to transfer 2 bytes using SPI in master mode and DMA. Additionally I have to set and reset CS signal by software. CS signal is low before starting transfer and is high after transfer.So...
Posted on September 04, 2013 at 21:37Hi,For my project I need additional RAM, is it possible to add memory to the STM32F407VG (in the STM32F4-Discovery Board) using the FSMC interface?
Posted on September 03, 2013 at 17:15Hi, i'm working with a STM32F207VGT and i dont achieve to wake up my board from STOP mode with the RTC. The RTC is configured with the LSI because the external crystal for LSE is not mounted. I have read another ...
Posted on September 04, 2013 at 08:22My platform's MCU is STM32f205. I try to modify TIM10_PWMOutput example from STM32F2xx Standard Peripherals Firmware Library to generate one PWM signal by using TIM10_CH1function of pin PB8. But it doesn't work?...
Posted on August 19, 2013 at 13:59I may have some spurious or unhandled interrupts and want to see where and when with software catch. Is there a default (in absence of specific) IRQ handler i can overwrite / install? (E.g. as you would with HardFa...
Posted on September 03, 2013 at 14:51hello, at the moment i'm working on the DMA-USART example from the FW library to fit into my application. the transmitting process(uC=> PC) is working as estimated, but the problem is i have to update the ''DMA...
Posted on February 10, 2012 at 20:00HelloSTM32RBT6 should control 1 servo with PWM output. For all TIM2 - TIM4 I tested it seems to be OK, but for TIM1 Channel 1 which is one I need it is working only occasionally what is very strange.Sometime I jus...
Posted on September 03, 2013 at 21:50Hi everyone, I have a problem with a stm32f207 device. I use the NSS pin of the SPI2 as a GPO. (The chip select to my SPI2 devices comes from an external I2C IO expander). NSS pin (I4) seems to be working ok as ...
