Hi, I am synchronizing two timers, actually already succeed but I was stuck two days because the trigger output event TRGO of TIM1 was connected to OC4REF (and CCR4 was accordingly set).With this configuration I didn't receive a pulse in the slave tr...
I read TS_CAL1 and TS_CAL2 values from stm32f303vc and saw that TS_CAL2 is lower then TS_CAL1. Is it correct? I think this is mistake. I check the memory with Visual Studio in debug mode and saw the same values. Why is it so?Thank u in advance!
I've a problem with UART on Bluepill (STM32F103C8T6). Let's say that I need to send some string via UART periodically using Std Peripheral Library . Below I post simple code which 'propably' should work. What I know for sure is that devices (bluepill...
HelloI'm very new to the STM world (just came from arduino) and I'm learning about timers and PWM. I have some questions about some settings that I cannot seem to find any answers. What is the difference between PWM mode 1 and 2And what is the differ...
Is there a fast way to use MCO, mux it to an internal clock souce and use a timer to realize some kind of on/off modulation of the MCO pin?I muxed it to an internal source and tried switching the GPIO between input and output. This works fine but nee...
Hi. I am trying to read 4 ADC Channels sequentially in interrupt mode: ADC2_IN7, ADC2_IN14, ADC2_IN15 and ADC2_IN8. However it only reads the last rank channel every time. Please help me understand what I'm doing wrong.Compiler: IAR Workbenc...
Hello,I am trying to implement I2S protocol for my project with STM32L433RBT6. I should play short (up to 5 seconds) .wav stereo audio samples that are with 44.1 kHz sampling rate and 16 bit audio sample. The I2S line goes into the CS4344 DAC. Thus, ...
I am developping a project around a F439 MCU, so I chose the NUCLEO-F439ZI to work with.I also ordered few NUCLEO expansion boards such as MEMS, TOF modules etc... Unfortunately, none of the project/examples provided with the expansion boards are pro...
Hello, I need to control signals in the order of nanoseconds magnitude (~ 100 ns). For this purpose, I have programmed a hardware timer in order to have an interrupt with 100 ns delay. I'm using a STM32F746VE microcontroller at 216 MHz. I'm using the...
Hello, I'm working with a STM32F746 microcontroller and communicating with a external driver with a parallel bus of 16 bits of data and 4 bits of address. I set the data to the parallel bus doing a sequencial write of the GPIOS of the ports involved ...
