HiCan you tell me how I can calculate a value for ARR for timer 2(32bit timer) and timer3(16bit timer)I am using STM32F407 APB1 timer clock is 12MHz prescaler is 6

HiMy board is STM32F407G so I want to understand the tx mailbox callback once interrupt hit I am sharing project in which I am sending CAN1 to CAN2 and CAN2 to CAN1 in loop back mode same ID.So rxindication is working fine and this is the project I g...

Hi I am using STM32F407 evb in which I have configured both CAN1 and CAN2 ,I am sendind CAN1(3 ids 501,502,503) and vice versa from CAN2 same I am sending but I am ble to recive all three id on CAN2 Rx but only one ID iam receving on CAN1(501) .I am ...

HiI have recheked my configuration and found it was 84mhz timer clock instead of 72Mhzso for 10 second I am loading 0x98967F in ARR and 83 i have loaded in PSC register but still timer is generating UIF flag sometimes in 7 seconds 4 seconds 2 seconds...

hiCan you suggest me a code in which there is generated interrupt using any timer

I am trying to run timer5 create interrupt for one minute .I have loaded 59,999,999 in ARR register and 71 in pSC prescaler register is it correct?I am sharing you screenshot of tim5 register at runtime but my timer is expiring at 50(approx.) second...

Hican you explain me this part ARR = 10000 - 1 and does this mean (PSC = 72 - 1) 71 value I have to load in prescaler register
