Hi there. I'm having a lot of trouble.I've managed to get UART (just direct calls, not interrupt based), PWM, and ADC working on a Nucleo board (namely, the STM32F070RB board). However, I'm having serious trouble getting a simple push-button to fire ...
Hi, AllI am using STM32F303CB to build a modbus environment which connected to RS485 bus. (BTW, MCU as slave side)I using STM32 HAL lib to setup whole UART & RS485 setting. I suppose DE pin waveform should be matched to Slave_Tx ( X wrong)-> The DE p...
Hello,I implemented a simple function generator as part of a project with a NUCLEO-L496ZG-P board.A cosine signal is generated using TIM2 (internal clock, no prescaler, period set by ARR value) -> DMA (with 256 point cosine table in memory) -> DAC (t...
I had build a host-client system , both host node and client node based on STM32F103C8T6. If host does not received client‘s [I'm alive] message though CAN bus for a while (about 2 seconds) , host power off client by turn off a P-Channel MOSFET, ...
I am using a STM32072B-EVAL board because I need a working demo about HDMI-CEC.It is clear that there are problems: the original firmware already on the board has errors about icons (some graphics is broken), about images (it hangs if try to show an ...
Registers "TIM3_CCR1" "TIM3_CCR2" that should hold the frequency and the duty cycle of the signal always equal zero
Hello,I want to use TIM3 as 32-Bit counter. Clock source is set to ETR2. The corresponding Pin is PA0. For test purpose I use TIM3 to generate a clock signal (Pin PC6) to feed the TIM3 counter.Connecting these to pins together (PA0 and PC6) results i...
I have an analog mic connected at an Audio Codec (MAX98090) which provides an I2S connectivity.I would like to connect this Codec over I2S to the STM32L4 . I have SensorTile and the Nucleo, both have the STM2L476 chip with 2 SAI ports to test the con...
Dear friends,there are two threads in my application , one is used for TCP/IP using lwIP and the other one is for RS485 protocol. Everything works fine correctly and I can send and receive data on RS485. After two or three hours or sometimes sooner, ...
Hello,I use stm32cubeH7 examples.I find in some of them call to sprintf, yet I don't understand where is the output of the sprintf goes to:I tried opening the "STMicroelectronics STLink virtual com port" - nothing is printed hereI also tried to searc...
