Posted on January 10, 2018 at 21:56Hello, I've just built the UART sample code for the 722ze Nucleo board and have a problem. I have not modified the code (except for the transmitted character buffer). The sample code shows setting up the unit for ...
A reference to an existing explanation would be fine.I can't find a reference manual
Hi everyone, I was just wondering if there was any STM32 MCU in a flip chip packaging configuration ? I have seen some BGA packages but I came to understand that it didn't mean that the chip was flipped inside...Any info on the matter would be appre...
Hi everyone,I'm slightly confused here.I'm putting my micro into stop mode, but I can't seem to wake it up using an interrupt.Here's how I'm setting it:__HAL_RCC_GPIOA_CLK_ENABLE(); GPIO_InitTypeDef GPIO_InitStruct; GPIO_InitStruct.Pin = GPIO_PIN_4...
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
