Hi,I want to realize ir transmitter with pwm signal but i do not understand the basic principle of pwm ir transmitter. What is the right way for creating ir transmit signal with pwm? Which peripherals must be used for this( pwm, timer interrupts...?)
Posted on January 26, 2015 at 11:58 Hello List, I,m struggling with reading, without DMA, from multiple channels. Every, say, 10 msec I call: var1 = Get_ADC_Value(11); var2 = Get_ADC_Value(12); Both variables ALWAYS get ...
Hi All,I'm trying to implement the eval board for a project seems like they have used a lot of different types of memory from HW perspective. I wanted to know what memory is being used for what purpose for this specific board so that I can change it ...
Hi,I need to generate a special waveform via DAC on a STM32F446. DAC samples must be generated at about 240kHz but with minimal jitter. A DMA channel with timer trigger will provide the data from internal RAM or flash. What best case - minimal - jit...
Hello everyone.I'd like to ask about the possibility of purchasing pre-programmed STM32 parts with our application.For now, we expect a low volume production in the mid term, but it is expected to grow around 1 year after product launch.Is it possibl...
Hello, my work mate made a design where we have to measure a low voltage in a smaller range (0-.120mV) on an Input.His assumption and hardware realization to meet the requirements based on datasheet DS10690 Rev 6. Here on page 63 you can find the ta...
I am encountering with a following problem in MCU STM32L432B.1. When the MCU enter to low-power mode (Stop 2) ones does not wake up while VDD is low than 2.1V, instead of it turns to mode with power consumption more 10ma. 2.When operation of the MCU...
STM32F446 RTCI seem to have a problem with this part of the MCU.I am using the HAL to retrieve date and time.Yesterday evening I set the time (about 22h something).Time was displayed correctly.Today in the morning I have a time of 33h27 retreived by ...
Hello, guys!I have problem saving data in STM32L0's flash memory.If I save the data twice in the same location it works fine.If I save the data once CRC check fails - data writing goes wrong?!I have attached my code.Sorry for the "magic" numbers in t...
