STM32H745 - Code is sometimes slow, but can be fixed by NOP
Hello,I have a rather strange problem on the CM7, where code executes with half or third the speed it should.I have no idea what is causing this, but I know how to fix it: by adding one or several NOPs somewhere in the code.Example: an ISR is taking ...
Resolved! What is the default timer clock frequency of APBx bus?
What is the default timer clock frequency of the APBx buses on an STM32F410RB? I've been considering it to be 16MHz to calculate the frequency of my PWM wave, but it turns out I get half the frequency on scope (is the default clock at 8MHz for timers...
STM32G030 Usart2 Overrun stops further reception
On G030 if an overrun occurs on usart2 (no FIFO available) the reception of further bytes stops.Is this intentional or an known error?
Resolved! Simulate a quadrature encoder on STM32F446RE
Noob here. Using HAL and as much generated code as possible. Ive run into an issue on how to self learn, I've identified what I believe is the solution but nowhere( that I can figure out) in the reference document does it point to this in what I ...
FDCAN_CCCR.Init bit is not getting cleared STM32H723ZG
Hi,I am trying to initialize FDCAN for my project. After the initialization I am clearing INIT bit in CCCR Register. The output what I can see is only CCE bit gets cleared but INIT bit is stuck at 1.Below is my code snippet.void Can_driver_init (void...
STM32U575 ADC1 Manually selecting ADC channel with regular rank.
Hi all,Currently I am working on a project using STM32U575ZG with both ADC1 and ADC4 enable.1. On both ADCs I have multiple channels enabled and every loop cycle the module will start single conversion on all of them.2. A second ADC task I would like...
Need suitable External Flash Loader - STM32F423ZHT6 GD25S512MDYIGR
Hi,I'm creating a project on GUI using an embedded wizard. While I'm trying to flash the code to my STM32F423ZHT6 custom board. It shows an error: failed to erase memory.I'm using STM32CubeProgrammer and I successfully erased the entire flash. But st...
I2C master quarter clock pulse
I am working with an STM32F405 and have the I2C1 peripheral set up as a master in standard mode with a clock speed of 100 kHz. The i2c bus has about 5 devices attached to it, none of which are capable of running in master mode. I'm using the HAL_I2...
H7 migration, send SPI without using HAL
Hello dear community!I've migrated from F7 to H7, everything fine so far.To save CPU time I don't want to use HAL for sending two SPI bytes.My F7 transmit SPI code was very simple and perfectly working :SPI6->DR = byte_0; SPI6->DR = byte_1;But on the...
