INVSTATE hard fault with SPI interrupt handler. STM32F405

I'm attempting to have my program run some code when a SPI transfer is complete using the RXNE flag. Setting the RXNEIE bit invokes SPI2_IRQHandler() as expected but it always results in a hard fault (CFSR register = 0x20000), without any additions t...

Source Code for STM32G071R External Loader

There is an external loader for the G0 series MCUs that comes with the M01 display kit. Does anyone know where the source code to that external loader is located at?

MCO capability

I'm working on a board redesign due to supply chain issue with a NXP MK70 MCU. The previous design clocked both the MK70 and a Spartan 6 FPGA with an external 50MHz crystal oscillator.The new design is using the STM32L4R9AII6 MCU -- max HSE input fre...

I want to measure the number of impulse for signal so I use a timer en mode ETR (signal like a horloge en extern de timer) But I don't know how Create this task

SPI data transfer is not working when using registers to initialize the SPI unit

I used this function to initialize and setup STM32H743IIT6 uC to work with SPI in master mode:void InitSPI(void) { RCC->APB2ENR=0x00102000; //Enabling SPI45 clock (default: rcc_pclk2=25MHz) SPI4->CFG1=0x30070007; //Baud rate = SPI clock / 16 = 1....

Measuring capacitance STM32L0-Disco

I'm trying to measure capacitance with my STM32L053-DiscoI'm using ADC and one output pin to charge the capacitor. I tried measuring time it takes for capacitor to charge to 62.3%.The problem that I'm facing is that the values that I'm getting from A...

Periodic Interrupt Timer with dynamic period set (programmatically) not being generated

Im in the process of configuring a STM32L432KC to talk with an AFBR-S50 sensor. This sensor needs a periodic interrupt to trigger measurements periodically. In the example they are using a timer with down counting direction to generate the interrupt ...

Hello, I want to use FMC with an adc AD7606. I don't know yet how FMC works; so my question is how i can read fmc_data ? can i consider fmc data bus as simple gpios and read them with Gpio_ReadPin?

STM32G070 as the alternative to STM32G081

ST has confirmed that STM32G070 uses same silicon as STM32G081, thus we're considering use it as the alternative to STM32G081 due to availability problems.STM32G070 lacks BOR feature and CEC hw block acc. to datasheet but we have proven by trial that...
