Hi, I'm testing a custom STM32WB09TEF7TR board. To communicate with the analog front end, I need to use SPI.However, SPI communication requires 17 us setting time, which means around 60 kHz.This speed is very slow.So, the Initiation of SPI becomes th...

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...

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...
