Posted on June 22, 2012 at 20:54Hi, I am using the STM32F103ZG device and looking through the reference manual (RM0008) I cannot find how, when a pin is configured as ''Input Pull-up/pull-down'', to select the pull-up or pull-down option. Having don...
Posted on June 21, 2012 at 09:40Hello.I have a probem with the ISO IN Endpoint. Double buffering is not working.The STM32F103RD is sending right data only from one buffer. Data from another buffer is wrong.My code: /* Initialize Endpoint 1 */ SetE...
Posted on June 07, 2012 at 18:46Hello, i connected sdcard to my stm32f4discovery board, used SDIO example for low level init, and fixed fatfs so i can write data and read that later with computer But fatfs code is to complex for me to understand, do...
Posted on June 22, 2012 at 12:56 I'm using a STM32F103RBT6.Basicly I want to clock TIM1 (it should work on this frequency because of the Fmax from APB2) external with an 25.5 Mhz signal and use the Update_IRQ. Thats all.I can start TIM1 and use the...
Posted on June 22, 2012 at 13:27I am writing a program to download and I do not know what this parameter.The size of the flash can I ask you?thank you
Posted on June 21, 2012 at 14:26The USB EP buffers defined in usbd_cc_core.cpp definitely NEED to be 4-byte aligned. Otherwise you end up in Memory-Alignment fault / Hard fault (if it is enabled by setting SCB->CCR |= 0x18 - this you definitely shou...
Posted on June 22, 2012 at 08:38In main function when we set or reset PA6, it will land into interrupt, while I have explicitly defined in EXTI9_5_IRQHandler , that only interrupt should happen on PA5 not on PA6. I don't know what is going on Please...
Posted on October 17, 2011 at 12:26STM32F2xx reference manual Doc ID 15403 Rev 3 doesn't list a Flash size register in chapter 33 Device electronic signature Is there really no such register? #missing-functionality
Posted on June 11, 2012 at 13:45Hello, I’m trying to get the uID from a STM32F207 microcontroller using the integrated bootloader connected through the USART1 (as described in AN3155). I’ve already implemented this feature for other microcontrol...
