Hello,I'm working with a STM32F446 and I configured the SPI as slave.In my process I receive x bytes of data in interruption. But during the process, this size of data changes to y. But the function HAL_SPI_TransmitReceive_IT(x) has already been call...
I'm writing some code with PWM and I'm using very high number of periods in short time causing my LED's to dim very choppy. I think it's not working properly because timer is to fast and counting in milliseconds and I need it to count in microseconds...
Hi, I'm working with a STM32F446ZET6. In this case, I configured my SPI as slave, and I use the HAL_SPI_TransmitReceive function.The problem is that when the slave shoud respond with the value 0x11, I receive 0x22 on the master side.I have checked th...
I have a brand new P-NUCLEO-IHM002 out of box. I configured it according to the instruction. however, when power up, D11 on IHM07M1 is not light at all. when i push the blue button, no response. LD3 on Nucleo-F302R8 is on, LD1 is flashing. Can you he...
I would be more than willing to participate regardless of time, but due to health reasons I can't stay up all night. I really need the workshop to get up to speed on the STM32H7 for a project I am working on. Thanks!
Right now the Hardware Acceleration Crypto Library only compiled for the F7 not F7, even though the H7 has more advanced Arch and Clock and can potentially better demonstrate the power of STM32 MCU. Is there a reason why ST discourage using H7 for c...
I have developed a dynamic loader that works in an STM32 (cortex-m4) microcontroller. Basically, the base firmware is in charge of writing new dynamic code into flash, and executing it. It works as expected. but I am trying to make the execution of t...
Hello,I am in the process of writing some code to drive WS2812B Leds with PWM via DMA. Unfortunately there are usually three pulses too much.Does anyone have an idea what this could be. Attached are a few excerpts from my program code. Thanksmain.cin...
