Hi,I found that TIMx_RCR functionality reversed w.r.t timer counter started from F103 to L475 as per the article. Here, I just want to know whether this bug is in the manual or is it reversed when comparing F103 to L475.Please find below two screensh...

Hi,I have a project which is based on the STM32L475RC and now I want to upgrade to the STM32L475RE controller. I have changed the device from STM32L475RC to STM32L475RE in options for the target of the Keil environment. But the new project based on t...

I am using the timer interrupt and currently, it has priority 3 once I get into the ISR then I want to change the priority to 2. I have used like below but the priority not changing.NVIC->IPR[6] |= NVIC_IPR6_PRI_25 & 0x22222222;__dsb(0);In above, __d...

Here below is the detail of my application.I am running the PWM timer1 at 5Khz in up-down mode. Two interrupts, one in timer counter equal to zero and ADC fast conversion done.Interrupt generates at every timer counter equal to zero then I start the ...

Hi, There is a feature provided by ST in the L475 controller that Modbus/RTU communication using USART. Can we ignore the USART RX interrupt as the end of block detection interrupt provided by this feature to collect the data?Is this block detection ...

No, I have tested in L475 but it is not working like that. I have written the odd value to RCR after launching the counter the UEV is occurring on underflow interrupt(when the counter starts up count).

I have tested in L475 and found that working like the description mentioned in the F103.

I agree. ST need to revise both the manuals with the correct solution.

I enabled the FPU module just after the main() in the RC project. It is working in RC but not working in RE. When I have disabled the FPU in RE then it is working fine. These are a few inputs along with the above. If I find any others I will share th...

I made a small mistake that's why it is not working and it is working now.Thank you all.
