Clearing USART (UART) interrupt flags in an STM32?
I am using an STM32F105 to communicate with a Linx GPS chip using a UART.
If I don't use interrupts (if I just poll the RX flag) then it works just fine. But I'm getting unexpected results when trying to use interrupts.
For example, if I only…

Turn on a microcontroller using a high-side Mosfet switch
I am using a P-Channel Mosfet to control the power of an STM32F103VETE ARM microcontroller (MCU1). The source of the Mosfet is connected to 3.3 V and the drain goes to the MCU1 Vdd pins. The gate of the Mosfet is controlled by another…

STM32F103 - Single pin shorted to VDD?
I have a custom STM32F103C8T6 board. Long story short, the MCU works fine, I can connect to it, program it, read sensors, toggle GPIO etc. The problem is that, one of the crucial pins seems to be shorted to VDD. The pin is PA9, which I wanted use…

How to (best) use a SPI SD card with STM32F1 or STM32F4?
Below, is the SD card reader I would like to use. It's using SPI.
On an Arduino I got it to work (using SPI).
However, I want to test it on a STM32F103C8T6, and later use it in STM32F407VET6. However, I see both the F1 and F4 can use the FATFS file…
