scope question on variable wrt I2C ??

I have the following two wrapper functions:void POT_Load_Value(uint16_t value) { uint8_t w[2]; w[0] = 0; //reg w[1] = value; I2C_Write(POT_ADDR, w, 2); }   uint8_t I2C_Write(uint8_t device, uint8_t *pValues, uint8_t size) { if (HAL_OK == HAL_I2C...

ADC conversion speed - I'd like to be able to achieve an ADC 16 bit conversion at up to 1MHz

I'm measuring on ADC1_IN0, triggered by a timer. I'm using an output pin to indicate the timing of the conversion start and completion. The ADC clock is 60MHz, clock prescaler async / 4. A 16 bit conversion appears to be taking about 6uS. What do I n...

MDIO bit banging data rate Hello, We have implemented MDIO(Management Data Input/Output) protocol by bit banging in the STM32 Nucleo-L series board and the corresponding frequency of MDIO is 2.8MHz as of now.

My requirement is to increase this frequency since the MCU operates at 110MHz. Kindly share your ideas ! --regards
