I am very new to embedded programming and I have to modify some code from other developers.I have to disable the outputs for a PWM and add a callback to get the state of the pulse instead of sending the pulse to the outputs.I was able to disable the ...
Hello, I'm using a stm32F103 to read 10 channel from the ADC in continuos mode. The ADC clock is 12Mhz and the sampling time is 28.5 cycles for all channels. the convertion time for one channel is ((28.5+12.5)/12Mhz) = 3.41 us. Since i'm using adc in...
Hello,I am developing a CAN bus application.I am new to the FDCAN peripheral and I haven't understood the difference between nominal bit time parameters and data bit time parameters.Which of these two groups of parameters should I configure to obtain...
Hello Team,I want to add external memory to NUCLEO-H745ZI board. In that board i have configured 2SPI, Ethernet (without RTIOS) and Timmer for that I need huge memory. This there any configuration or steps to add external memory to board. Best Regard...
I am using CANFD with an STM32H7 and a transceiver that is compatible with CANFD and CAN 2.0 (ISO1044BDR).I can see that in the configuration the CANFD can be used as a CAN 2.0. What I want to know is what is the easiest way to integrate the flexibil...
Hi everyone!I found the following diagramm in AN2606 and my understanding was, that the bootloader will be executed when there is no valid content in flash memory.I know that boot pins or a jump from user code can be used to enter the ST bootloader, ...
Hello,I am using an STM32F407G-DISC1 to run an open source program called Picovoice. More specifically their project at the following link (https://github.com/Picovoice/picovoice/tree/master/demo/mcu/stm32f407/stm32f407g-disc1). Unfortunately they do...
Edit: I found the problem, and it is of course my own fault. Careful reading of the transceiver chip datasheet reveals that the Rx pin follows the Tx pin by design on some models, including mine. Leaving this post up for posterity. I'm having an issu...
Hello,I'm a bit confused about stack management on Cortex M7.In my SW I only use the MSP.I understood that the MSP can only be modified with a MSR instruction. However the SP can be modified with a "simple" LDR instruction.Does that mean that when I ...
This is not a discussion on the 'U0 as such (that'd need some time to sink in); just comment on the 'L0->'U0 migration document, AN6091. It's a very detailed and extensive document, and following items are just relatively insignificant minor issues/t...
