Resolved! how does HAL_ADC_Start_DMA() behave if the DMA is set to half_word

HAL_ADC_Start_DMA() takes a pointer to a uint32_t buffer, but the cubeMX can configure the DMA for word, half_word or byte.So therefore you can only configure the DMA for word transfers?I was setting the cubeMX to half_word or uint16_t and using 12bi...

Resolved! I2C Slave address

Hello everyone!I am making a project with STM32F072 MCU and I have 3 devices that need to be controlled via I2C: a DAC, an ADC and a current monitor that has an ADC integrated. I've made the connections and part choices so that I have 3 different 7-b...

Resolved! How can I view the number of ADC conversions per second?

Resolved! The correct value cannot be read without resetting after flash writing with the B-U585I-IOT02A

I use B-U585I-IOT02A to read after writing Flash Memory, 0xFF is read, but once I reset it, I can read the written value.Similarly, when I use it to read after erasing the Flash Memory, the value before erasing is read, but once I reset it, I can rea...

Resolved! Timer 1 Hallsensor interface - No interrupt from external signal.

This is how i the GPIO for the timer:// Hallsensors (Tim1 capture) my_GPIO_InitStruct.Pin = GPIO_PIN_0 | GPIO_PIN_1 | GPIO_PIN_2; my_GPIO_InitStruct.Mode = GPIO_MODE_AF_PP; my_GPIO_InitStruct.Pull = GPIO_PULLUP; HAL_GPIO_Init(GPIOC, &my_GPIO_Init...

Resolved! How to set a nand flash with FMC?

Hi there,I want to try touchGFX on my homemade board with the STM32F429BIT6 and a band flash chip H27U1G8F2B.I initial the FMC NAND flash by following the code:and test the NAND flash as below:The LOG output is like this(the data value sometimes chan...

Resolved! HAL_Delay() stopped working after touchGFX initial?

Hi there,I am trying a touchGFX demo on my homemade board with STM32H743IIT6.Everything is OK except the HAL_Delay() is not working after the MX_TouchGFX_Init().The following code works well: ... MX_GPIO_Init(); MX_FMC_Init(); MX_CRC_Init();...
