I'm having the same trouble as many on here in that I can't persuade USART1 of my STM32F4 to come out with the correct baud rate. My transmitted data appears as garbage when received at 115,200 and if I attach a Saleae logic probe to the Tx pin it me...
The STM32F407xx datasheet (DocID022152 Rev 8) specifies on page 113 that a supply overvoltage is applied to each power supply pin, in conformance to the EIA/JESD 78A. What is the applied voltage profile? The standard specifies 1.5 x Vmax for a T up t...
I need to have ADC1 and ADC2 run sumultaneously. Each ADC has 2 injected channels. I want to start the ADC once and then have it constantly run converting the 4 injected channels, putting the result in the 4 associated JDR registers and raising a fla...
Hello,Does STM32F7 support differential or pseudo analog reading?Also Other than that if we read two single ended channels which are connected to a differential pair and then in software we do the common mode rejection does it have the same performan...
Example. The MCU should wake up automatically every 5 seconds. This is possible with the RTC. But are there other ways to achieve this? (so not using the rtc?) Timers don't seem to work because the clock is turned off.
NUCLEO-F103RB with STM32F103RBI want to use the DMA in a burst mode to write data from buffer in RAM to the TIM1_CCR1,2,3,4? that are in PWM mode. DMA burst transaction is requested on the TIM1 Update (UEV). Number of transactions in Burst mode is se...
I want to use RTC module in STM32. Eventhough i try to update the date and time registers, their values are not updated. I have given my code. I would be thankful, if someone can point out what is the wrong with my procedure. uint32_t _Time_Tens=0,_T...
