Multi-Channel ADC and I2C

I'm using an IMU 9250 (who works with I2C) and I need use at least 4 ADC single-ended channels. but, unfortunately, I'm not able to accomplish it. When the STM32f303k8 has the code (i2c + 4 channel ADC with DMA) and the 4 ADC pins are not physically ...

Why is this code not being able to change the default SPI value of 0 to 1, and also the bit shift on timer is not working

#define SPI2_CR2 *(__IO uint32 *)0x40003800#define timer4_CR2 *(__IO uint32 *)0x40000800void setup() { Serial.begin(115200);}void loop() { Serial.println("SPI"); Serial.println(SPI2_CR2,BIN); SPI2_CR2=SPI2_CR2|(1<<0); Serial.println(SPI2_CR2,BIN); Se...

DAC in STM32F4 and STM32F7 poor accuracy

I am trying the DAC in the STM32F4, so far I am using just the HAL_set_value function and I am trying to get a clear output voltage. I am using the STM32F46 nucleo board.I see that the ripple at the output (using the internal amplifier) is far highte...

RTC of stm32l031k6 counting more

I want to use RTC of stm32l031k6. But once I tested it I noticed that it counts 8 seconds more in a minute. I need a precise rtc. Do you have any advise what should I do.Thanks,

PSRAM with 32-bit data bus width?

According to the STM32F4/F7 data sheet FMC controller support 32-bit bus PSRAM. For my application I would like to use this configuration, due to a high bandwidth requirement. However, in the market it seems very difficult to find a PSRAM with 32-bit...
