Hi. I'm developing a custom STM32 circuit board.I'm trying to use an analog-front-end, AD7124-8 ADC chip.However, this chip generates an interrupt signal through the MISO pin when data is ready. As you know, once we set SPI in STM32, we cannot use G...

Hi. I'm developing a custom board using STM32WB09TEF7TR microcontroller.I had a problem re-accessing the microcontroller using SWD once I finished programming one time.I found that it is due to the SPI3 (PA3) and one GPIO pin (PA2) sharing the pin fo...

Hi. I have a problem with the STM32WB09KE board.I'm trying to activate Bluetooth LE using this developer board but the BLE init function returns this error massage. Success: aci_hal_write_config_data command - CONFIG_DATA_PUBADDR_OFFSETSuccess: aci_h...

I'm trying to use STM32WB09KE for the BLE application. However, unlike STM32WB55, this microcontroller must activate PKA and RNG for the BLE module.So, I did.However, after generating the BLE code, I tried to build the project in the IDE and it showe...

In the case of Espressif, when we write the main() function and build the project, all the necessary components start being set up from that point. Unlike CubeMX, which requires structuring everything beforehand, Espressif’s approach significantly re...

TDK's comment suggests that the SPI pins can also be used as interrupts. This was mentioned in a previous thread as well. The problem is that when I try to configure the SPI MISO pin with a GPIO interrupt, the microcontroller freezes, and I cannot de...

Sorry. I gave up. :(I'll use a timer-interrupted SPI. :( :(STM32 is wasting my time a lot.They should learn how Espressif does.CubeMX is the source of evil because it generates code that we need to modify :(, which means that we have to understand ST...

I tried to set the MISO pin as the GPIO Interrupt pin in the MX_GPIO_Init(). ---------------GPIO_InitStruct.Pin = GPIO_PIN_8; // -> this is actual interrpt pin using MISO pinGPIO_InitStruct.Mode = GPIO_MODE_IT_FALLING;GPIO_InitStruct.Pull = GPIO_NOPU...
