I want to make i2c monitor that can read data sent by slave with specific address (0x42). So monitor has to capture sequence of1. Start2. Slave address (write)3. Command byte 4. Repeated start 5. Slave address (read)And then start reading actual dat...
I have a sensor which generate an input signal. By using this signal rising edge , I want to generate some pwm signals and additional Dac signal from DMA which synchronize with input Signal. When I visualize signals on ossiloscope , I aware some sli...
Hi, I am using the 176 Pin STM32F407 microcontroller. I want to generate the phase correct PWM using timer 4 ch1 and ch2, so please guide me for the same. The wave form is attached for driving a dual input boost converter. The "gate driver" image is ...
I have 36 leds on my board. I will connect dimmer my board. How can i adjust leds brightness with dimmer? Because i need to manage 36 output pins. How can i do it?
Hi,I want to interface two SPI peripherals on the same STM32H743 nucleo, am configuring SPI1 as Master and other as Slave and connecting them with each other. Am transmitting in polling mode via SPI1 and receiving in interrupt mode on SPI3. I am rece...
Any ideas why values would be non linear in the approximately the upper 1 to 2 bits?For the setup below, it is linear to between -17000 to +14000. Doubling the + output only yields around +18000. These are raw values. This really acts like an overflo...
STM32H7 SPI configured as Master with the Clock Phase and Clock Polarity 0 (mode 0). During the HAL_SPI_TransmitReceive() call, before the CLK the pulse is observed on the MOSI signal. Due to this the slave device is behaving differently. Agree the...
uint64_t write = 0x1111111122222222;HAL_FLASH_Unlock();if(HAL_FLASH_Program(FLASH_TYPEPROGRAM_DOUBLEWORD,0x0807F000,write)==HAL_OK) { HAL_GPIO_WritePin(GPIOG,GPIO_PIN_12,GPIO_PIN_RESET); } HAL_FLASH_Lock();
The STM32F3DISCOVERY board's main perk are the MEMS gyro and MEMS accelerometer/magnetometer combo.In different revisions of the board, these chips were changed (whatever was the reason). This of course has impact on working of software, including ex...
