Posted on October 12, 2011 at 10:48Hi, I need to reset individual bits in already written word/byte in the on-chip flash (from 0x0800 0000). The problem is that according to Programming manual PM0075 (STM32F10xxx Flash memory microcontrollers) : Fla...
Posted on October 14, 2011 at 13:08Dear all, I''m facing some problems with FSMC configuration. I've STM32F103ZE connected with M29W640GT NOR async non multiplexed flash external memory. I've already read AN2784 and studied STM32F10xxx firmware lib...
Posted on September 30, 2011 at 08:33I am using STM32F105RC microcontroller on a custom designed board, the microcontroller runs at 72MHz, no crystal (& its decoupling caps) is connected for RTC, CR2032 3V battery is connected to Vbat directly (no o...
Posted on October 14, 2011 at 04:53Hi all: The device is connected to PC via USB. The software I use is DFUse demonstration V2.2, I can use the software to turn the device into DFU mode, and make it exit the mode too. But after load DFU file and cli...
Posted on October 13, 2011 at 13:58Hello all, I have linebuffer[256] and want to quickly send it to GPIOB15-8. In TIM2_IRQ, I enable DMA and TIM3 is used for DMA requests. I am trying following configuration: RCC->APB1ENR = RCC_APB1ENR_TIM2EN | RC...
Posted on October 07, 2011 at 11:21Hello, I'd like to know if there is a unique ID available on each STM32F10x, that can be read from ROM, and that can not be changed by the user. I would like to realise a copy-protection function with that ID. if...
