Posted on May 10, 2014 at 17:58HelloI am searching for the way how to protect my chip. It should:- protect flash memory from reading in all cases, even if somebody flashes his own firmware.- allow to upload new firmware with stock bootloader (usart)...
Posted on May 09, 2014 at 13:45Hello guys!I am currently working on a thesis project where my task is to establish a communication between the USB port of the board (custom board) with STM32f405ZG microcontroller.Could you please guide me how to sta...
Posted on May 10, 2014 at 16:47I am working on a sine wave program as a part of an Amateur Radio project. I have a working code producing what I want using TIM3-- PWM and PORTC. I am unfortunately unable to neither change the TIM3 to any other TIM...
Posted on January 22, 2013 at 08:32Hi, I am using STM32f4discovery board and am trying to write a code which will take moving average of accelerometer data. For this purpose my average variable have to be in floating point. But during initialization...
Posted on May 10, 2014 at 14:12 Hello, I am having a strange problem where my UART1 remap is getting dependent on I2C1 remap. Following is the scenario: If I configure only UART1, remapped to PB6/7 it does not workWhen I enable the rema...
Posted on May 09, 2014 at 22:09Hello everybody.I want to solve a read problem in a special hardware, the configuration of each pin is input:RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOA | RCC_AHB1Periph_GPIOB | RCC_AHB1Periph_GPIOC | RCC_AHB1Periph_GP...
Posted on May 09, 2014 at 19:14I have been reading the ''PM0075'' Programing manual STM32F10xxx Flash memory micro-controllers and I am trying to understand the mass erase feature. In the manual it states:''Bit 2 MER: Mass eraseErase of all user pa...
Posted on April 29, 2014 at 20:24I'm working on the STM32F439-EVAL. I've created my own project using STM32Cube and am able to use SWO output and see the logs on the IAR terminal IO window (I'm using IAR). In order to compare some of the bootup proc...
Posted on May 09, 2014 at 15:48Hello, i'd like to do output compare on four pins: PE13, PE9 (LEDS), PA10 and PA12. Everyone works except PA12. I tried to do that with TIM16 and TIM4 with no luck. And i reconfigured the channels, i understand how the...
Posted on May 09, 2014 at 14:34I have been looking in the stdlib libraries (v 1.0.2) for the STM32F401VE, and there does not seem to be any support for SPI4, even though it is listed as existing in the datasheet and reference manual. What gives?Have...
