Hello, After looking over all the documentation I could find (datasheet, source primer, etc.), I couldn’t easily find how I’m meant to connect IR LED (s) for Ir DA communication with an STM32WB55. The image I attached is a screenshot from ...Read more
Hi, For enabling the automatic password sequencing you can write 1 to bit PAR of WDTCPUyCON1 (or WDTSCON1 for safety watchdog) Register. For example, if you want to enable automatic password sequencing for CPU0 you can do it like this (IfxScuWdt_getCpuWatchdogPassword()); = 1; (IfxScuWdt_getCpuWatchRead more
Hi,
For enabling the automatic password sequencing you can write 1 to bit PAR of WDTCPUyCON1 (or WDTSCON1 for safety watchdog) Register. For example, if you want to enable automatic password sequencing for CPU0 you can do it like this
(IfxScuWdt_getCpuWatchdogPassword()); = 1; (IfxScuWdt_getCpuWatchdogPassword());
After enabling this point the password changes automatically after each password check and follows a pseudorandom sequence based upon a 14-bit Fibonacci LFSR with characteristic polynomial x14 x13 x12 x2 1 as you said. So each time you have to calculate the new password grounded on this sequence.

Hello, IrDA has hardly been used for a long time, which is also marked in discontinued IrDA transceivers. However, since basically everything except the TIA and visual factors is included in the STM32 IrDA SIR ENDEC, it's possible to recreate IrDA with an IR LED plus driver transistor and an IR photRead more
Hello,
IrDA has hardly been used for a long time, which is also marked in discontinued IrDA transceivers. However, since basically everything except the TIA and visual factors is included in the STM32 IrDA SIR ENDEC, it’s possible to recreate IrDA with
RX and TX are switched to the IrDA function so that the LED driver and TIA can be connected directly.
