Posted on January 14, 2016 at 16:43The default examples are for the Discovery board running at 72MHz. Mine is running at 65.536MHz, meaning that I need to adjust the baudrate to get the round number I desire eg 1M, 500k, 250k, 125k etc.It is not obv...
Posted on July 10, 2013 at 15:27I need to output a simulated quadrature signal on two mcu pins. Is there a way to cleanly do this using the advanced timing features of TIM1 & TIM8?I know that there are other ways that essentially amount to using tim...
Posted on January 14, 2016 at 11:06To sample the temperature sensor I am using the HAL_ADCEx_InjectedConfigChannel. Since the ADC_CHANNEL_TEMPSENSOR and ADC_CHANNEL_VBAT share ADC channel, only one of them can be sampled at a time, depending on the ...
Posted on September 26, 2014 at 02:00I am using an STM32F427 processor and wish to implement a USB device CDC virtual serial port on the HS USB port. I am generating my initialization/driver code with CubeMX. I am having a hard time figuring out wha...
Posted on January 13, 2016 at 04:53Hi Everyone. I've looked through some of the older posts re: timer delay function, and I have used one of those posts as a base to what I have implemented. The problem is, when I run the delay function in a loop to...
Posted on January 12, 2016 at 22:06How do you recognize, which edge lead to EXTI, if it is configured for rising and falling edges?Now, I look a state of that pin in IDR register, immediately when EXTI occurs. But in that time, between cause of inte...
Posted on February 12, 2013 at 16:17Hello, I am able to accurately capture one PWM input on each 16- and 32-bit timers on the STM32F4x and STM32F3x Discovery boards (using IC1 and IC2). But, I have not had any luck capturing two PWM singnals on a si...
Posted on January 13, 2016 at 17:06I would like to see an example about how to drive a LCD with F10X or F20X. Like bit banking RW/WR and handling data. I saw something for Nucleo boards, but I wonder would that help with other boards.
Posted on January 13, 2016 at 10:23Hello,I try to use the RTC M41T93 with a microcontroler STM32L052. I use the SPI1 for the communication. It seems to work well as I am able to read the time, to write the time and some registers.The problem is that...
Posted on January 11, 2016 at 11:46 Hi Guys, I am setting up my F427 with a master-slave timer (TIM4->TIM1). TIM4 triggers two capture and compare interrupts, CC2 (CCR2 = 1), and CC4 (CCR4 = 5000). TIM1 is triggered by CC2 signal. ...
