Posted on March 06, 2012 at 13:40Hello, while studying the STM32F4xx datasheet i found the following passage:25.3.1: ''The NSS signal is driven low when the master starts the communication and is kept low until the SPI is disabled.'' This leads me ...
Posted on April 16, 2012 at 22:16Hi all, I am currently using the STM3210C evaluation board and have discovered something which is puzzling, and has to do with the clock frequencies. I am currently using Atollic to program the board and have initia...
Posted on April 21, 2012 at 16:32Hi all, I'm building a custom bootloader and need to provide a way to write protect/unprotect the memory. In order to commit the change, a system reset is required, which I sought to be a software-triggered reset. Fi...
Posted on April 23, 2012 at 21:16It looks to me like the hardware for Tim4 will support PWM input capture on channel 3/4,but when I look at the source code for the standard peripheral library (V3.5.0) the procedureTIM_PWMIConfig appears to be hardw...
Posted on March 16, 2012 at 13:34Hello, I’m trying to force my device (STM32F417) into system memory boot without physically setting the boot pins (cannot access them) and resetting the board i.e. jump to it from my application when the user reque...
Posted on April 23, 2012 at 11:29Hi, I'm trying to test the Audio_playback_and_record Project in the STM32F4-Discovery board, but even if I use the bin file included in the fw package(V1.1.0), the audio quality of the digital mems microphone is very...
Posted on April 20, 2012 at 09:26 Hello, i try to configure the CAN on a STM32F103R8. I would like to use the filter to block messages. Only messages with the ID 0x701, 0x581, 0x185, 0x285, 0x385, 0x485, 0x205 and 0x305 shall not be bloc...
Posted on April 22, 2012 at 08:16I have configured my time 1 to operate in the PWM mode1 to generate a signal of fixed duty cycle. I want the generate an update INT every 4 th overflow of the TIM1 CNT . I have loaded value 4 into my repetition count...
Posted on April 22, 2012 at 22:03Here is a Simple Project Change ... Running Your Project / Discovery Board off ONLY ONE SINGLE AA BATTERY ! :Did you know - that you may be able to run your Projects (like a Stm32 Board, Stm32F4disc, Stm32LDisc, etc)...
Posted on April 21, 2012 at 08:27Hi Everyone, I have developed a program on STM3210E-Eval, in which I have configured both USART1 and USART2 to send data on their respective interrupts. Unfortunately only USART2 is sending data. UART1 is not sending...
